Description

本発明は、油圧クラッチ及びブレーキを用いて制御する自動変速機に関し、特に入力軸と中継軸及び出力軸の3軸が平行に配置され、入力軸に変速用部材を配置した前進6速から10速を有する前輪駆動用の多段自動変速装置に関する。 The present invention relates to an automatic transmission that is controlled using a hydraulic clutch and a brake, and in particular, from the 6th forward speed to the 10th forward speed in which three axes of an input shaft, a relay shaft, and an output shaft are arranged in parallel, and a speed change member is arranged on the input shaft. The present invention relates to a multi-stage automatic transmission for front wheel drive having a high speed.

周知の如く、近年地球環境問題のため自動車の省燃費の要求は強く、車両用自動変速装置の前進6速以上への多段化が進められている。特に多用されている前輪駆動用の自動変速装置においては、現状の変速装置以上に軸方向を長くすることは許されなく、機構をシンプルにすると同時に軸方向がコンパクトになる構造が求められている。前進6速後進1速のシンプルなギアトレンとして、4個の構成要素を持った2個の遊星歯車列の、3個の構成要素に選択的に減速回転と非減速回転を入力し、そのうちの2個の構成要素にブレーキを配し、残りの1個の構成要素を出力するシンプルな前進6速後進1速の車両用自動変速装置が考案されている。1個の構成要素に減速回転を入力し、他の2個の構成要素に非減速回転を入力した特許文献1と、2個の構成要素に減速回転を入力し、他の1個の構成要素に非減速回転を入力した特許文献2である。 As is well known, in recent years, there has been a strong demand for fuel efficiency of automobiles due to global environmental problems, and multistage stages of automatic transmissions for vehicles to 6 or more forward speeds are being promoted. Especially in the automatic transmission for driving the front wheels that is frequently used, it is not allowed to make the axial direction longer than the current transmission, and there is a demand for a structure that simplifies the mechanism and at the same time makes the axial direction compact. . As a simple gear train of 6 forward speeds and 1 reverse speed, selectively input decelerated rotation and non-decelerated rotation to 3 components of 2 planetary gear trains with 4 components. There has been devised a simple automatic forward 6-speed reverse vehicle 1-speed vehicular transmission in which a brake is arranged on each component and the remaining one component is output. Patent Document 1 in which deceleration rotation is input to one component and non-deceleration rotation is input to the other two components, and deceleration rotation is input to the two components, and one other component It is patent document 2 which input the non-decelerated rotation.

前輪駆動用の車両に実用化された前進6速後進1速の自動変速装置としては特許文献2で提案された方式のSAE TECHNICAL PAPER に記載された非特許文献がある。このギアトレンの速度線図及び適切な変速比を本願記載の図26に示す。図26の4個の構成要素A、B、C、Dを持った2個の遊星歯車列を示す速度線図において、2個の構成要素に減速して入力する入力軸の減速比を1.5前後とし、前進減速段におけるクラッチC1から入力する要素をDとし、出力要素をCとし、ブレーキB1及びB2を有する要素をそれぞれB、Aとすると、各要素の位置関係を示すB−C間に対するC−D間及びA−B間の距離比を1.6及び2.2前後とすれば適切な変速比が得られる。ここで従来用いられてきた2個の遊星歯車列を検証すると、このような比率がとれる速度線図を有した4個の構成要素からなる2個の遊星歯車列として、リングギアを出力としたラビニョー遊星歯車を用いる特許文献と、互いの遊星キャリアとリングギアを連結した2個の遊星歯車列を用いる特許文献がある。この2種の遊星歯車列は上記比率がとれる遊星歯車列のうち最も欠点が少なく、現在前進4速後進1速の自動変速装置として最も多く実用されているものである。 Non-Patent Document 1 described in SAE TECHNICICAL PAPER of the method proposed in Patent Document 2 is an automatic transmission device of 6 forward speeds and 1 reverse speed that has been put to practical use in a vehicle for driving front wheels. A speed diagram of this gear train and an appropriate gear ratio are shown in FIG. 26 of the present application. In the velocity diagram showing the two planetary gear trains having the four components A, B, C, and D in FIG. 26, the reduction ratio of the input shaft that is decelerated and input to the two components is 1. Between 5 and 5 indicating the positional relationship of each element, assuming that the element input from the clutch C1 in the forward deceleration stage is D, the output element is C, and the elements having the brakes B1 and B2 are B and A, respectively. If the distance ratio between CD and AB is about 1.6 and 2.2, an appropriate gear ratio can be obtained. Here, when two planetary gear trains that have been conventionally used are verified, the ring gear is output as two planetary gear trains composed of four components having a velocity diagram that can take such a ratio. There are Patent Document 3 using Ravigneaux planetary gears and Patent Document 4 using two planetary gear trains in which each planet carrier and ring gear are connected. These two kinds of planetary gear trains have the fewest disadvantages among the planetary gear trains having the above ratios, and are most practically used as automatic transmissions for forward 4 speeds and reverse 1 speeds.

特許文献2に記載の図14及び非特許文献に記載された入力軸と同軸に配された前進6速後進1速の自動変速装置は、この前進4速後進1速の自動変速装置と同じ形態を採っている。つまり、入力におけるクラッチの接続構成要素はA、B、Dであり、ブレーキの接続構成要素はA、Bであり、出力構成要素はCであり且つ又速度線図におけるB−C間に対するC−D間及びA−B間の距離比も同じとなる。入力軸の減速回転は1個のピニオン遊星歯車を有した3個の構成要素からなる減速用遊星歯車によって得られ、1個の構成要素に入力し、他の1個の構成要素を固定することにより残りの1個の構成要素が減速して出力される。この入力軸の減速回転の構成要素A、Dへの連結のため、特許文献で用いられる互いの遊星キャリアとリングギアを連結した2個の遊星歯車列は各クラッチ及びブレーキの連結が成立せず、特許文献に用いられたリングギアを出力するラビニョー遊星歯車のみ前進6速後進1速の自動変速装置として成立する。 The automatic transmission of 6 forward speeds and 1 reverse speed arranged coaxially with the input shaft described in FIG. 14 described in Patent Document 2 and Non-Patent Document 1 is the same as the automatic transmission apparatus of 4 forward speeds and 1 reverse speed. It takes a form. That is, the clutch connection components at the input are A, B, and D, the brake connection components are A and B, the output component is C, and C- The distance ratio between D and AB is also the same. Deceleration rotation of the input shaft is obtained by a planetary gear for reduction consisting of three components with one pinion planetary gear, input to one component and fix the other one component The remaining one component is decelerated and output. In order to connect the input shaft to the components A and D of the reduced speed rotation, the two planetary gear trains connected to each other and the planetary gear used in Patent Document 4 are connected to each clutch and brake. However, only the Ravigne planetary gear that outputs the ring gear used in Patent Document 3 is established as an automatic transmission for 6 forward speeds and 1 reverse speed.

ラビニョー遊星歯車は周知の如くロングピニオンギアを共有したシングルピニオンとダブルピニオン遊星歯車からなり、遊星キャリアを共有するため軸方向にコンパクトでシンプルに配列できるが、2列の遊星歯車間でロングピニオンギアが異なるベクトルで噛合うため、ロングピニオンギアが傾き歯面の当たり方が悪くなる基本的な欠点を有する。非特許文献の前進6速後進1速の自動変速装置では前進1、2、3、4速段で歯面の当たり方が悪くなる状態となる。加えて、ダブルピニオン遊星歯車を用いるためスペース的に通常サンギアと噛合うピニオン遊星歯車が3個、工夫をしても4個が限界となり、サンギアの入力トルクのピニオン遊星歯車への分散に限界が生じる。又、リングギアの歯数を、クラッチC1を介して入力するサンギアの歯数で割った値が2.6程度と比較的大きな値となり、実際のスペースにおいてサンギアの径を大きくすることができなくトルクが入力するサンギアの歯面荷重が大きくなる。非特許文献の前進6速後進1速の自動変速装置では前進の1〜4速段において入力軸トルクが1.5倍前後に増幅されこのサンギアに入力するため、さらに不利となる。又、前進6速後進1速の自動変速装置では前進1速段の変速比を前進6速段の変速比で割った値が燃費及び牽引特性向上のため、非特許文献における6前後以上となる大きな値を要求される場合がある。しかし、ラビニョー遊星歯車ではリングギアの歯数をサンギアの歯数で割った値をさらに大きくしなければならなく実用に即さない。尚、ラビニョー遊星歯車では最も質量が大きくアンバランスとなる遊星キャリアの軸支も片持ちで不安定とならざるを得ない。 The Ravigneaux planetary gear consists of a single pinion and a double pinion planetary gear that share a long pinion gear, as is well known. Are engaged with different vectors, the long pinion gear has a basic disadvantage that the inclination of the tooth surface becomes slanted. In the automatic transmission of the sixth forward speed and the first reverse speed of Non-Patent Document 1, the contact of the tooth surface becomes worse at the first, second, third, and fourth speeds. In addition, because of the use of double pinion planetary gears, there are three pinion planetary gears that mesh with the sun gear in space, and four even if devised, there is a limit to the dispersion of the input torque of the sun gear to the pinion planetary gears. Arise. Moreover, the value obtained by dividing the number of teeth of the ring gear by the number of teeth of the sun gear input via the clutch C1 is a relatively large value of about 2.6, and the diameter of the sun gear cannot be increased in an actual space. The tooth load on the sun gear to which torque is input increases. In the automatic transmission of the sixth forward speed and the reverse first speed of Non-Patent Document 1 , the input shaft torque is amplified by about 1.5 times and input to the sun gear at the first to fourth forward speeds, which is further disadvantageous. In addition, in an automatic transmission of 6 forward speeds and 1 reverse speed, a value obtained by dividing the transmission ratio of the first forward speed by the transmission ratio of the sixth forward speed is about 6 or more in Non-Patent Document 1 in order to improve fuel efficiency and traction characteristics. May be required to be a large value. However, in Ravigneaux planetary gears, the value obtained by dividing the number of teeth of the ring gear by the number of teeth of the sun gear must be further increased, which is not practical. In the Ravigneaux planetary gear, the planetary carrier, which has the largest mass and is unbalanced, must be cantilevered and unstable.

2個の構成要素に減速回転を入力する特許文献2の方式において、入力軸と同軸に配すことができ、リングギアを出力するラビニョー遊星歯車以外に本願記載の図26の速度線図と同様のA、B、C、Dの位置関係を有した4個の構成要素からなる2個の遊星歯車列は、本願記載の図27に示したサンギアとリングギア及び遊星キャリア同士を連結した組み合わせが存在する。この遊星歯車列はラビニョー遊星歯車における強度面での難点が克服できるが、前進5,6速の高速段において動力が2個の遊星歯車を通過し、増速されて後減速される伝達効率の悪い状態となる。特に高速走行では高速段に変速比を固定した連続走行となるため伝達効率が直接燃費に影響し、このような遊星歯車列は不適切となる。 In the method of Patent Document 2 in which reduced rotation is input to two components, it can be arranged coaxially with the input shaft, and is the same as the velocity diagram of FIG. 26 described in the present application except for the Ravigneaux planetary gear that outputs a ring gear. The two planetary gear trains composed of the four components having the positional relationships of A, B, C, and D of FIG. 27 are a combination of the sun gear, the ring gear, and the planet carriers shown in FIG. Exists. This planetary gear train can overcome the difficulties in strength of Ravigneaux planetary gears. However, the transmission power of two or more planetary gears in the forward 5th and 6th speed stages is increased and then reduced. It will be in a bad state. In particular, in high-speed running, since continuous running is performed with the gear ratio fixed at a high speed, transmission efficiency directly affects fuel consumption, and such a planetary gear train is inappropriate.

軸方向のコンパクトさが必須となる前輪駆動用の自動変速装置においては、クラッチの配置が重要となり、油圧サーボ機構をコンパクトにすること及び摩擦部材を遊星歯車の外周に配置することが有効な手段となる。2個のクラッチを出力カウンターギア前部の減速用遊星歯車に配し、1個のクラッチを出力カウンターギア後部の2個の遊星歯車列に配したコンパクトな構造となる手段が特許文献で提案されている。しかし、この配置は2個のクラッチを出力カウンターギア前部に配し、1個のクラッチを出力カウンターギア後部の2個の遊星歯車列に配した前進4速の特許文献と、2個のクラッチを減速用遊星歯車の近傍に配する前進6速の特許文献2に記載の図14、さらには、2個のクラッチを2個の遊星歯車列の前部に配し、1個のクラッチを後部に配した前進4速の特許文献から類推可能である。つまり、特許文献2の図14の非減速回転を伝達する1個のクラッチを特許文献の如く2個の遊星歯車列の後部に配置転換し、出力を特許文献のように中央からカウンターギアで出力したものである。又、これら特許文献2、3、5、6に用いられている入力軸と同軸に配された2個の遊星歯車列の実施例はリングギアを出力とするラビニョー遊星ギア列に限られており、このタイプの前進6速と従来の前進4速とのギアトレンの類似性は前述した通りである。 In an automatic transmission for front wheel drive where axial compactness is essential, the arrangement of the clutch is important, and it is effective to make the hydraulic servo mechanism compact and to place the friction member on the outer periphery of the planetary gear. It becomes. Patent Document 5 proposes a compact structure means that two clutches are arranged on the reduction planetary gear at the front of the output counter gear and one clutch is arranged on the two planetary gear trains at the rear of the output counter gear. Has been. However, this arrangement is disposed on the output counter gear front two clutches, and Patent Document 6 forward fourth speed which arranged one clutch two planetary gear trains of the output counter gear rear, two FIG. 14 described in Patent Document 2 of 6-speed forward where the clutch is arranged in the vicinity of the planetary gear for reduction, and further, two clutches are arranged at the front part of the two planetary gear trains, and one clutch is arranged. It can be inferred from Patent Document 3 of forward four-speed arranged in the rear part. That is, one clutch that transmits the non-decelerated rotation in FIG. 14 of Patent Document 2 is rearranged at the rear part of two planetary gear trains as in Patent Document 3 , and the output is counter gear from the center as in Patent Document 6. Is the output. Further, the embodiments of the two planetary gear trains arranged coaxially with the input shaft used in these Patent Documents 2, 3 , 5 , and 6 are limited to Ravigne planetary gear trains that output ring gears. The similarity of the gear train between this type of forward 6th speed and the conventional forward 4th speed is as described above.

尚、特許文献では減速用遊星歯車をボス部の先端に配し、その両側にクラッチの油圧サーボを配したため、後方側クラッチの油圧サーボへの油の供給が入力軸を通す形態となる。したがって、油の通過穴の形成上入力軸を2体化し、後部の1個のクラッチに連結しなければならず複雑でコスト高な構造となる。 In Patent Document 5 , the planetary gear for reduction is arranged at the tip of the boss portion, and the hydraulic servo of the clutch is arranged on both sides thereof, so that the oil supply to the hydraulic servo of the rear clutch passes through the input shaft. Therefore, in order to form an oil passage hole, two input shafts must be formed and connected to one rear clutch, resulting in a complicated and expensive structure.

この2個の構成要素に減速回転を入力し、他の1個の構成要素に非減速回転を入力した前進6速後進1速のギアトレンをベースにさらなる多段化を図ったものが提案されている。上記前進6速後進1速のギアトレンの構成要素Aに、減速回転に加え非減速回転を入力して前進8速とした特許文献と、構成要素Dに、減速回転に加え非減速回転を入力して前進10速とした特許文献である。これらに用いられている2個の遊星歯車列はリングギアを出力とするラビニョー遊星ギア列となっており、前輪駆動用としての実施例が示された特許文献ではリングギアを出力とするラビニョー遊星ギア列以外に本願記載の図27に示したサンギアとリングギア及び遊星キャリア同士を連結し、共有する遊星キャリアを出力したものが記載されている。しかし、前述した如くこのギアトレンはオーバドライブとなる高速段において遊星ギアの伝達効率の悪い不適切なギアトレンとなる。尚、前進段を6速からさらに増やす変速段を有した上記自動変速装置では、前進1速段の減速比をさらに大きくとる必要があるため遊星歯車列への負荷は増し、強度的な欠点を有したラビニョー遊星歯車列は益々不利となる。 There has been proposed a multi-stage gear train based on a forward 6-speed reverse 1-speed gear train in which a deceleration rotation is input to the two components and a non-deceleration rotation is input to the other component. . Patent Document 7 in which non-decelerated rotation is input in addition to decelerated rotation to component A of the forward 6-speed reverse 1-speed gear train, and non-decelerated rotation in addition to decelerated rotation is input to component D Patent Document 8 in which the forward speed is 10th. The two planetary gear trains used in these are Ravigneaux planetary gear trains that output ring gears, and in Patent Document 8 showing an embodiment for driving front wheels, Ravigneaux that output ring gears are used. In addition to the planetary gear train, the sun gear, the ring gear and the planet carrier shown in FIG. 27 described in the present application are connected to each other and the shared planet carrier is output. However, as described above, this gear train is an inappropriate gear train with poor transmission efficiency of the planetary gear at a high speed stage that is overdriven. Incidentally, in the above automatic transmission having a gear stage that further increases the forward gear from the sixth speed, it is necessary to further increase the reduction ratio of the first forward gear, so the load on the planetary gear train is increased and the strength disadvantage is reduced. The Ravigne planetary gear train that we have becomes increasingly disadvantageous.

前進6速後進1速のもう一つのシンプルなギアトレンとして、前述した4個の構成要素を持った2個の遊星歯車列の、1個の構成要素に減速回転を入力し、他の2個の構成要素に非減速回転を入力した特許文献1の方式がある。この4個の構成要素の速度線図では、本願記載の図26における速度線図のAとD及びBとCを入れ替えた組み合わせの位置関係とすれば適切な変速比を得ることができる。ラビニョー遊星歯車を用いれば本願記載の図28に示したような遊星キャリアを出力するギアトレンで書き表せる。この構造では前進5,6速の高速段において動力がダブルピニオン遊星歯車を通過し、シングルピニオン遊星歯車を通過するリングギアを出力するラビニョー遊星歯車に比べダブルピニオン遊星歯車が高速回転となり伝達効率が悪化する不適切な遊星歯車列となる。尚、適切な変速比とするにはリングギアの歯数をサンギアの歯数で割った値を3程度と大きな値にしなければならず実用上問題となる。通常リングギアの歯数をサンギアの歯数で割った値は1.5〜2.8が好ましい。 As another simple gear train of 6 forward speeds and 1 reverse speed, the reduced rotation is input to one component of the two planetary gear trains having the four components described above, and the other two There is a method of Patent Document 1 in which non-decelerated rotation is input as a component. In the velocity diagrams of these four components, an appropriate gear ratio can be obtained if the positional relationship is a combination of A and D and B and C in the velocity diagram in FIG. If a Ravigneaux planetary gear is used, it can be expressed by a gear train that outputs a planet carrier as shown in FIG. In this structure, the double pinion planetary gear rotates at a higher speed than the Ravigne planetary gear that outputs the ring gear that passes through the single pinion planetary gear and outputs the ring gear through the single pinion planetary gear at the high speed stages of the forward 5th and 6th speeds. It becomes an inappropriate planetary gear train that gets worse. In order to obtain an appropriate gear ratio, the value obtained by dividing the number of teeth of the ring gear by the number of teeth of the sun gear must be set to a large value of about 3, which is a practical problem. Usually, the value obtained by dividing the number of teeth of the ring gear by the number of teeth of the sun gear is preferably 1.5 to 2.8.

しかしながら、この前進6速後進1速のギアトレンでは、本願記載の図28における速度線図が示すように前進1速から4速段において構成要素Dへの入力が減速用遊星歯車を介さないため効率がよく、しかもトルク増幅がないため強度的に減速用遊星歯車を介する方式の前進6速後進1速のギアトレンより有利となる。加えて、前進4速段では動力が全く遊星歯車を通らない減速比1:1の状態ができること、及び前進段で減速用遊星歯車を通過する入力側トルクは前進3速と5速段で入力軸トルクの3割以下となり、減速用遊星歯車が軽負荷となることも有利な点となる。 However, in this forward 6-speed reverse 1-speed gear train, as shown in the speed diagram in FIG. 28 of the present application, the input to the component D does not go through the planetary gear for reduction in the forward 1st to 4th gears. In addition, since there is no torque amplification, it is more advantageous than the gear train of the sixth forward speed and the reverse first speed using the planetary gear for reduction. In addition, at the fourth forward speed, a reduction ratio of 1: 1 can be achieved in which the power does not pass through the planetary gear at all, and the input side torque passing through the reduction planetary gear at the forward speed is input at the third forward speed and the fifth speed stage. The shaft torque is 30% or less, and the reduction planetary gear is lightly loaded.

そこで、本願発明者は特許文献でサンギアとリングギア及び互いの遊星キャリアを連結した2個の遊星歯車列を用いた1個の構成要素に減速回転を入力し、他の2個の構成要素に非減速回転を入力した前進6速後進1速の自動変速装置を提案した。この2個の遊星歯車列の組み合わせでは前進の減速段で2個の遊星歯車列を動力が通過するため効率的には1個の遊星歯車列を通過する方式より不利となるが、リングギアの歯数をサンギアの歯数で割った値が2.2前後と大きくしなくても適切な変速比を得ることができる。尚、この構造では本願記載の図27に示した同じ組み合わせの2個の遊星歯車列と比べ入出力の構成要素が異なるため、前進5,6速の高速段において動力は1個の遊星歯車列しか通過せず伝達効率の悪化はない。特許文献の提案は減速用遊星歯車と2個の遊星歯車列を出力カウンターギアの保持部材で分離させ、2個の遊星歯車列側に非減速回転を入力する2個のクラッチを配したものである。又、本願発明者は特許文献10で前進6速から10速の多様な後輪駆動用自動変速装置を提案している。車両用自動変速装置の前進6速以上への多段化にあたっては単に多段化をすればよいのではなく、変速比、伝達効率、シンプル・コンパクトを満足し耐及性に優れたものが要求される。本発明は本願発明者による特許文献9、10をベースに、強度的に問題のあるリングギアを出力するラビニョー遊星歯車列に代わり、2個のシンプル遊星歯車列を用いて前述した2種のタイプの前進6速と前進8速及び前進10速の多様な用途に対応可能でコンパクトな前輪駆動用多段自動変速装置を提案するものである。 Therefore, the inventor of the present application inputs a reduced speed rotation to one component using two planetary gear trains in which a sun gear, a ring gear, and each planetary carrier are connected in Patent Document 9 , and the other two components. Proposed an automatic transmission with 6 forward speeds and 1 reverse speed in which non-decelerated rotation was input. The combination of the two planetary gear trains is more disadvantageous than the method of passing through one planetary gear train because the power passes through the two planetary gear trains at the forward reduction stage. An appropriate gear ratio can be obtained even if the value obtained by dividing the number of teeth by the number of teeth of the sun gear does not increase to around 2.2. In this structure, the input / output components are different from those of the two planetary gear trains of the same combination shown in FIG. 27 described in the present application. Therefore, the power is one planetary gear train at the forward fifth and sixth speeds. However, the transmission efficiency does not deteriorate. In the proposal of Patent Document 9, a planetary gear for reduction and two planetary gear trains are separated by a holding member of an output counter gear, and two clutches for inputting non-decelerated rotation are arranged on the two planetary gear trains. It is. Further, the inventor of the present application has proposed various automatic transmissions for driving rear wheels ranging from 6 to 10 forward speeds in Patent Document 10 . When the automatic transmission for a vehicle is to be multi-staged to 6 or more forward speeds, it is not necessary to simply make multi-stage, but a gear ratio, transmission efficiency, simple and compact, and excellent durability are required. . The present invention is based on Patent Documents 9 and 10 by the inventor of the present application. Instead of the Ravigne planetary gear train that outputs a ring gear having a problem in strength, the two types described above are used by using two simple planetary gear trains. The present invention proposes a compact multi-stage automatic transmission for front wheel drive that can be used for various applications such as forward 6-speed, forward 8-speed and forward 10-speed.

本発明の第1の課題は、前進6速から10速までをなし得る多段自動変速装置に関し、燃費を考慮しなければならない高速連続走行状態のオーバドライブとなる高速段において1個のシンプル遊星歯車しか動力が通過しなく、且つリングギアとサンギアの歯数比を大きくしなくてもワイドな変速比を得ることのできる強度的に有利な、4個の構成要素を有した2個のシンプル遊星歯車からなる共通の遊星歯車列を提供することである。 A first object of the present invention relates to a multi-speed automatic transmission that can achieve 6 to 10 forward speeds, and one simple planetary gear in a high-speed stage that is an overdrive in a high-speed continuous running state where fuel consumption must be considered.

Since the input side torque passing through the reduction planetary gear 40 at the forward speed is less than 30% of the input shaft torque at the third forward speed and the fifth speed stage, a large thrust force is also applied to the ring gear R0 serving as the helical gear. A simple ring gear R0 holding method is established as described above.

A1の変速形態は図5の速度線図で示されるように、前進1速から4速段において構成要素Dへの入力が減速用遊星歯車を介さない点、前進4速段では動力が全く遊星歯車を通らない減速比1:1の状態ができる点、前進段で減速用遊星歯車を通過する入力側トルクは前進3速と5速段で入力軸トルクの3割以下となり減速用遊星歯車が軽負荷となる点等、効率及び強度やトルク容量の両面で優れた形態を有している。この変速形態を有効に活かすには第1、第2遊星歯車列20、30の構成要素A、B、C、Dの位置関係が重要となる。尚、最高速段となる前進6速段で動力はシンプル遊星歯車列のみを通過するのが効率上の条件となることより必然的に構成要素A、B、Cが第1遊星歯車列20のサンギアS1、遊星キャリアP1、リングギアR1となる。また、牽引力の関係上前進6速と5速の変速比の比率を1.2倍とし前進5速と4速の変速比の比率を1.3倍程度とするのが望ましく、前進4速段の変速比が1に固定されるため前進6速段の変速比が1.2×1.3=1.56の逆数となる0.64、前進5速段の変速比が0.64×1.2=0.77と自ずと決定される。前進6速段の変速比を0.64とするには構成要素A、B間を構成要素B、C間の1.8倍程度とすればよく、第1遊星歯車列20のリングギアとサンギアの歯数をZR1、ZS1とするとZR1/ZS1=1.8となる。また、前進5速段の変速比を0.77にするための減速用遊星歯車40のリングギアとサンギアの歯数をZR0、ZS0とするとその歯数比も自ずと決定される。実際の遊星歯車では歯車が噛み合うための条件があるため、図5の如くZR1/ZS1=1.8、ZR0/ZS0=1.938として前進6速段の変速比0.643、前進5速段の変速比0.777を得ることができる。 As shown in the speed diagram of FIG. 5, the speed change mode of A1 is that the input to the component D does not go through the reduction planetary gear at the first forward speed to the fourth speed, and the power is completely planetary at the fourth forward speed. A reduction ratio of 1: 1 that does not pass through the gears can be achieved, and the input side torque that passes through the reduction planetary gear at the forward speed is less than 30% of the input shaft torque at the third forward speed and the fifth speed, and the reduction planetary gear is It has an excellent form in terms of efficiency, strength, and torque capacity, such as a light load. In order to make effective use of this speed change mode, the positional relationship between the components A, B, C, and D of the first and second planetary gear trains 20 and 30 is important. It should be noted that since it is an efficient condition for the power to pass through only the simple planetary gear train at the sixth forward speed, which is the highest speed, the components A, B, and C are inevitably included in the first planetary gear train 20. The sun gear S1, the planet carrier P1, and the ring gear R1. Further, it is desirable that the ratio of the speed ratio between the 6th forward speed and the 5th speed is 1.2 times and the ratio of the speed ratio between the 5th forward speed and the 4th speed is about 1.3 times because of the traction force. Is fixed at 1, so that the speed ratio of the sixth forward speed is 0.64 which is the reciprocal of 1.2 × 1.3 = 1.56, and the speed ratio of the fifth forward speed is 0.64 × 1. .2 = 0.77. In order to set the gear ratio of the sixth forward speed to 0.64, the distance between the components A and B may be about 1.8 times between the components B and C, and the ring gear and sun gear of the first planetary gear train 20 If the number of teeth is ZR1, ZS1, ZR1 / ZS1 = 1.8. Further, if the number of teeth of the ring gear and the sun gear of the reduction planetary gear 40 for setting the gear ratio of the fifth forward speed to 0.77 is ZR0, ZS0, the gear ratio is also automatically determined. In actual planetary gears, there are conditions for the gears to mesh with each other. Therefore, as shown in FIG. 5, ZR1 / ZS1 = 1.8, ZR0 / ZS0 = 1.938, the forward gear 6 speed ratio is 0.643, and the forward fifth gear. A gear ratio of 0.777 can be obtained.

前進の1速から3速段の減速段における変速比は構成要素B、C間と構成要素C、D間の比率で決まり、その比率を2.7から3.3とすると前進1速を前進6速段の変速比で除したギアレンジが5.8のクロスなものから6.8のワイドなものまで選定できる。実際の自動変速装置における遊星歯車においては、スペースの関係上リングギアの歯数をサンギアの歯数で割った値が1.5〜2.8の範囲内とするのが好ましく、構成要素B、C間と構成要素C、D間の比率を2.7から3.3にした場合構成要素B、C、Dをシンプル遊星歯車にはできなく、図5のように第2遊星歯車列30のリングギアR2を構成要素Aとし、遊星キャリアP2を構成要素Bとし、サンギアS2を構成要素DとすればリングギアR2とサンギアS2の歯数比ZR2/ZS2=2〜2.4の比較的小さな値で構成要素B、C間と構成要素C、D間の比較的大きな比率2.7〜3.3を得ることができる。図5では歯数比ZR2/ZS2=2.25の中間値をとりギアレンジを6.3とした。 The gear ratio in the first to third forward speeds is determined by the ratio between the components B and C and the components C and D. If the ratio is changed from 2.7 to 3.3, the first forward speed is advanced. The gear range divided by the 6th gear ratio can be selected from a cross range of 5.8 to a wide range of 6.8. In the planetary gear in an actual automatic transmission, the value obtained by dividing the number of teeth of the ring gear by the number of teeth of the sun gear is preferably in the range of 1.5 to 2.8 because of space, and the component B, When the ratio between C and the components C and D is changed from 2.7 to 3.3, the components B, C, and D cannot be simple planetary gears, and the second planetary gear train 30 of FIG. If the ring gear R2 is the component A, the planet carrier P2 is the component B, and the sun gear S2 is the component D, the gear ratio ZR2 / ZS2 = 2 to 2.4 of the ring gear R2 and the sun gear S2 is relatively small. By value, a relatively large ratio of 2.7 to 3.3 between the components B and C and between the components C and D can be obtained. In FIG. 5, an intermediate value of the gear ratio ZR2 / ZS2 = 2.25 is taken and the gear range is set to 6.3.

クラッチC1とブレーキB1を締結し、構成要素D(S2)に非減速回転を入力し構成要素B(P1、P2)を固定する。実際の遊星歯車列における動力の伝達は、第2遊星歯車列30のサンギアS2に入力された動力は遊星キャリアP2が固定されるためリングギアR2が逆転し減速され第1遊星歯車列20のサンギアS1に入力され、遊星キャリアP1が固定されるためさらにリングギアR1が正回転に減速され出力される。したがって、大きな減速比が得られる。尚、図5には示されていないが、ブレーキB1の代わりにワンウェイクラッチOWCで構成要素B(P1、P2)を固定しても同じとなる。
The operation and reduction ratio from 1st (first forward speed) to 6th (sixth forward speed) and Rev (reverse speed) in the A1 speed change mode will be described with reference to FIG.
<1st>
The clutch C1 and the brake B1 are engaged, and non-decelerated rotation is input to the component D (S2) to fix the component B (P1, P2). In the actual transmission of the planetary gear train, the power input to the sun gear S2 of the second planetary gear train 30 is fixed to the planet carrier P2, so that the ring gear R2 is reversely rotated and decelerated and the sun gear of the first planetary gear train 20 is transmitted. Since it is input to S1 and the planet carrier P1 is fixed, the ring gear R1 is further decelerated to the forward rotation and output. Therefore, a large reduction ratio can be obtained. Although not shown in FIG. 5, it is the same even if the component B (P1, P2) is fixed by the one-way clutch OWC instead of the brake B1.

The clutch C1 and the brake B2 are engaged, and non-decelerated rotation is input to the component D (S2) to fix the component A (S1, R2). In the actual transmission of the planetary gear train, the planetary carrier P2 is decelerated because the power input to the sun gear S2 of the second planetary gear train 30 is fixed to the ring gear R2, and the planet carrier of the first planetary gear train 20 is thus decelerated. Since the sun gear S1 is fixed, the speed is increased and the total speed is reduced and output from the ring gear R1.

Clutch C1 and clutch C3 are engaged, non-decelerated rotation is input to component D (S2), and decelerated rotation is input to component A (S1, R1). In the transmission of power in the actual planetary gear train, the non-reduced rotation is input to the sun gear S2 of the second planetary gear train 30 and the reduced rotation is input to the ring gear R2, so that the planet carrier P2 is decelerated and the first planetary gear train is transmitted. The ring gear R1 of the gear train 20 is slightly increased by the sun gear S1 and the planet carrier P1, and is totally decelerated and output.

<4th>
クラッチC1とC2を締結し、構成要素D(S2)と構成要素B(P1、P2)に非減速回転を入力する。実際の遊星歯車列における動力の伝達は、第2遊星歯車列30のサンギアS2と遊星キャリアP2が連結され、リングギアR2は入力回転と同じ回転となる。したがって、第1遊星歯車列20のサンギアS1と遊星キャリアP1も連結され、リングギア23は入力回転と同じ回転で出力される。
<4th>
The clutches C1 and C2 are engaged, and non-decelerated rotation is input to the component D (S2) and the component B (P1, P2). For transmission of power in the actual planetary gear train, the sun gear S2 of the second planetary gear train 30 and the planet carrier P2 are connected, and the ring gear R2 has the same rotation as the input rotation. Therefore, the sun gear S1 of the first planetary gear train 20 and the planet carrier P1 are also connected, and the ring gear 23 is output at the same rotation as the input rotation.

<5th>
クラッチC2とクラッチC3を締結し、構成要素B(P1、P2)に非減速回転を入力し、構成要素A(S1、R2)に減速回転を入力する。実際の遊星歯車列における動力の伝達は、第1遊星歯車列20の遊星キャリアP1に非減速回転が入力され、サンギアS1に減速回転が入力されるため、リングギアR1は少し増速されて出力される。この場合、第2遊星歯車列30は動力の伝達はしない。
<5th>
Clutch C2 and clutch C3 are engaged, non-decelerated rotation is input to component B (P1, P2), and decelerated rotation is input to component A (S1, R2). The actual transmission of power in the planetary gear train is such that the non-reduced rotation is input to the planet carrier P1 of the first planetary gear train 20 and the reduced rotation is input to the sun gear S1, so that the ring gear R1 is slightly accelerated and output. Is done. In this case, the second planetary gear train 30 does not transmit power.

The actual transmission of power in the planetary gear train is output by speeding up the ring gear R1 because the non-reducing rotation is input to the planet carrier P1 of the first planetary gear train 20 and the sun gear S1 is fixed. In this case, the power second planetary gear train 30 does not transmit power.

ブレーキB1とクラッチC3を締結し、構成要素A(S1、R2)に減速回転を入力し、構成要素B(P1、P2)を固定する。実際の遊星歯車列における動力の伝達は、第1遊星歯車列20のサンギアS1に減速回転が入力され、遊星キャリアP1が固定されるため、リングギアR1が減速され逆回転で出力される。
<Rev>
The brake B1 and the clutch C3 are engaged, the decelerated rotation is input to the component A (S1, R2), and the component B (P1, P2) is fixed. The transmission of power in the actual planetary gear train is output by decelerating rotation to the sun gear S1 of the first planetary gear train 20 and fixing the planet carrier P1, so that the ring gear R1 is decelerated and output by reverse rotation.

A1の変速形態において、減速比が大きくとれる前進1速段では第2遊星歯車列30で約2.25倍に減速された動力が第1遊星歯車列20のサンギアS1に入力されサンギアS1には大きなトルクが加わる。そこで、図21と図22に示すように第2遊星歯車列30ではピニオン遊星歯車の個数を4個としたのに対し、第1遊星歯車列20ではピニオン遊星歯車の個数を1.5倍の6個としサンギアの径を1.2倍とすれば歯面荷重が減少し歯幅の増加を押さえることができる。 In the speed change mode of A1, at the first forward speed where the reduction ratio can be increased, the power decelerated about 2.25 times by the second planetary gear train 30 is input to the sun gear S1 of the first planetary gear train 20 and is input to the sun gear S1. A large torque is applied. Therefore, as shown in FIGS. 21 and 22, the number of pinion planetary gears in the second planetary gear train 30 is four, whereas in the first planetary gear train 20, the number of pinion planetary gears is 1.5 times. If the number of sun gears is six and the diameter of the sun gear is 1.2 times, the load on the tooth surface is reduced and the increase in the tooth width can be suppressed.

2個の構成要素に減速回転を入力し、他の1個の構成要素に非減速回転を入力した前進6速後進1速の多段自動変速装置の特許文献2と同じ変速形態をA2とし図11から図13に示す。図11の速度線図の構成要素A、B、C、Dは変速形態をA1とする図5と同じ第1、第2遊星歯車列20、30の構成要素である。したがって、第1、第2遊星歯車列20、30とクラッチC2、ブレーキB1及びワンウェイクラッチOWCの配置はA1の変速形態と同じくできる。入力軸3の回転は直接クラッチC2を介して第2構成要素B及びシングルピニオン遊星歯車からなる減速用遊星歯車40のリングギアR0に入力され、サンギアS0を固定した減速用遊星歯車40の遊星キャリアP0を介した入力軸3の減速回転はクラッチC1、C3を介して第4、第1構成要素D、Aに入力され、第1、第2構成要素A,BはブレーキB2、B1で制動される。ここで、多様な形態をとる第1と第4構成要素の入力装置部REは減速用遊星歯車40と、クラッチC1、C3と、ブレーキB2とからなっている。図11の模式図及び図12は図1、図3の空白となる入力装置部REにA2タイプの構造を挿入したものである。 The same speed change form as in Patent Document 2 of the multi-speed automatic transmission of 6 forward speeds and 1 reverse speed in which reduced rotation is input to two components and non-decelerated rotation is input to the other one component is designated as A2. To FIG. The components A, B, C, and D in the velocity diagram of FIG. 11 are the components of the first and second planetary gear trains 20 and 30 that are the same as those in FIG. Therefore, the arrangement of the first and second planetary gear trains 20, 30 and the clutch C2, the brake B1, and the one-way clutch OWC can be the same as the transmission mode of A1. The rotation of the input shaft 3 is directly input to the ring gear R0 of the reduction planetary gear 40 comprising the second component B and the single pinion planetary gear via the clutch C2, and the planetary carrier of the reduction planetary gear 40 to which the sun gear S0 is fixed. The reduced speed rotation of the input shaft 3 via P0 is input to the fourth and first components D and A via the clutches C1 and C3, and the first and second components A and B are braked by the brakes B2 and B1.

A2の変速形態は図11の速度線図で示されるように、前進1速から4速段において構成要素Dへの入力が減速用遊星歯車を通過するので、A1の変速形態と比べ効率及び強度やトルク容量の面で不利となる。この変速形態において第1、第2遊星歯車列20、30の構成要素A、B、C、Dの位置関係はA1の変速形態のように前進1速段の変速比を前進6速段の変速比で割った値が6前後とクロスな変速比を得るのには不向きではあるが、さらなる燃費及び牽引特性向上のため大きな値を要求される場合に適している。構成要素A、B間と構成要素B、C間の比率と構成要素C、D間と構成要素B、C間の比率を1.9前後とし、減速用遊星歯車40の歯数比を1.5前後にとればワイドで適切な変速比を得ることができる。したがって図11のようにZR1/ZS1=1.897、ZR2/ZS2=1.535、ZR0/ZS0=1.809にとれば前進1速段4.523から前進6速段0.655の前進1速を前進6速段の変速比で除したギアレンジが6.91となるA1の変速形態以上のワイドなものが選定できる。 As shown in the speed diagram of FIG. 11, the speed change mode of A2 is more efficient and stronger than the speed change mode of A1 because the input to the component D passes through the reduction planetary gear at the first forward speed to the fourth speed. And disadvantageous in terms of torque capacity. In this speed change mode, the positional relationship between the components A, B, C, and D of the first and second planetary gear trains 20 and 30 is the same as that of the speed change mode A1. Although it is not suitable for obtaining a cross ratio with a value obtained by dividing the ratio by about 6, it is suitable when a large value is required to further improve fuel consumption and traction characteristics. The ratio between the constituent elements A and B and the constituent elements B and C and the ratio between the constituent elements C and D and the constituent elements B and C are about 1.9, and the gear ratio of the reduction planetary gear 40 is 1. If it is around 5, a wide and appropriate gear ratio can be obtained. Therefore, as shown in FIG. 11, when ZR1 / ZS1 = 1.897, ZR2 / ZS2 = 1.535, ZR0 / ZS0 = 1.809, the forward 1st forward speed 4.523 to the forward 6th speed 0.655 forward 1 A gear wider than the A1 speed change mode in which the gear range obtained by dividing the speed by the gear ratio of the sixth forward speed is 6.91 can be selected.

A2の変速形態における1st(前進1速段)から6th(前進6速段)及びRev(後進段)の作動と変速比を示す図11において、全ての変速段におけるクラッチ、ブレーキの締結要素はA1の変速形態と同じとなる。A1の変速形態と異なるのは前進1速から前進4速段まで構成要素Dへの入力が減速用遊星歯車40を通過することである。従って前進3速段では第1、第2遊星歯車列20、30の歯車が固定され、前進4速段では回転することがA1の変速形態と異なる。前進5,6速段及び後進段はA1の変速形態と同じとなる。 In FIG. 11 showing the operation and the gear ratio from 1st (first forward speed) to 6th (6th forward speed) and Rev (reverse speed) in the speed change mode of A2, the engagement elements of the clutches and brakes at all speed stages are A1. This is the same as the speed change mode. The difference from the A1 speed change mode is that the input to the component D passes through the reduction planetary gear 40 from the first forward speed to the fourth forward speed. Therefore, the gears of the first and second planetary gear trains 20 and 30 are fixed at the third forward speed, and the gears of the first and second planetary gear trains are rotated at the fourth forward speed. The fifth and sixth forward speeds and the reverse speed are the same as the shifting mode of A1.

A2の変速形態において、減速比が大きくとれる前進1速段では減速用遊星歯車40で入力トルクが1.55倍に増幅され第2遊星歯車列30のサンギアS2に加わる。しかし、A1の変速形態のZR2/ZS2=2.25に対しA2の変速形態ではZR2/ZS2=1.535であるためリングギアの径を同じとすればサンギアS2の径は2.25/1.535=1.46倍となり強度的にはA1の変速形態とほぼ同じとなる。さらに、図23に示すようにピニオン遊星歯車の個数をA1の変速形態の図21に示す4個の1.5倍の6個としているので強度的にはA1の変速形態より有利になる。第1遊星歯車列20のサンギアS1には減速用遊星歯車40で入力トルクが1.55倍に増幅されさらに第2遊星歯車列30で約1.535倍の1.55×1.535=2.38倍に入力トルクが増幅される。A1の変速形態では2.25倍に入力トルクが増幅されA2の変速形態の1.55倍より大きなトルクがサンギアS1に加わり、ZR1/ZS1の比率もほぼ同じため、A1、A2の両変速形態とも第1遊星歯車列20の強度は同じにできる。このように、A2の変速形態はA1の変速形態と比べ減速用遊星歯車40を通過する頻度が増え効率の面で不利となるが、強度に有利な第1、第2遊星歯車列20,30の歯数となるのでA1の変速形態と強度面ではかわらない。 In the speed change mode A2, the input torque is amplified 1.55 times by the reduction planetary gear 40 and applied to the sun gear S2 of the second planetary gear train 30 at the first forward speed where the reduction ratio is large. However, since ZR2 / ZS2 = 1.535 in the A2 transmission mode as compared to ZR2 / ZS2 = 2.25 in the A1 transmission mode, the diameter of the sun gear S2 is 2.25 / 1 if the diameter of the ring gear is the same. .535 = 1.46 times, and the strength is almost the same as the shifting mode of A1. Furthermore, as shown in FIG. 23, the number of pinion planetary gears is six, which is 1.5 times the four shown in FIG. The input torque of the sun gear S1 of the first planetary gear train 20 is amplified by 1.55 times by the reduction planetary gear 40 and 1.55 × 1.535 = 2, which is about 1.535 times by the second planetary gear train 30. The input torque is amplified by 38 times. In the A1 speed change mode, the input torque is amplified by 2.25 times, and a torque larger than 1.55 times that of the A2 speed change mode is applied to the sun gear S1, and the ratio of ZR1 / ZS1 is substantially the same. In both cases, the first planetary gear train 20 can have the same strength. As described above, the speed change mode of A2 is disadvantageous in terms of efficiency because the frequency of passing through the reduction planetary gear 40 is increased compared to the speed change mode of A1, but the first and second planetary gear trains 20 and 30 are advantageous in terms of strength. Therefore, the speed change mode and strength of A1 do not change.

A2の変速形態の構成要素Aに、減速回転に加え非減速回転を入力して前進8速とした特許文献と同じ変速形態をA3とし図14から図16及び図24に示す。図14の速度線図の構成要素A、B、C、Dは変速形態をA1とする図5と同じ第1、第2遊星歯車列20、30の構成要素である。したがって、第1、第2遊星歯車列20、30とクラッチC2、ブレーキB1及びワンウェイクラッチOWCの配置はA1の変速形態と同じくできる。入力軸3の回転は直接クラッチC2を介して第2構成要素B及びダブルピニオン遊星歯車からなる減速用遊星歯車40の遊星キャリアP0に入力されると同時に遊星キャリアP0からクラッチC4を介して第1構成要素Aに入力され、サンギアS0を固定した減速用遊星歯車40のリングギアR0を介した入力軸3の減速回転はクラッチC1、C3を介して第4、第1構成要素D、Aに入力され、第1、第2構成要素A,BはブレーキB2、B1で制動される。ここで、多様な形態をとる第1と第4構成要素の入力装置部REは減速用遊星歯車40と、クラッチC1、C3、C4と、ブレーキB2とからなっている。図14の模式図及び図15は図1、図3の空白となる入力装置部REにA3タイプの構造を挿入したものである。 FIG. 14 to FIG. 16 and FIG. 24 show A3 as the same speed change form as in Patent Document 7 in which the non-decelerated rotation is input in addition to the reduced speed rotation to the component A of the speed change form A2, and the forward speed is 8th. Components A, B, C, and D in the velocity diagram of FIG. 14 are components of the first and second planetary gear trains 20 and 30 that are the same as those in FIG. Therefore, the arrangement of the first and second planetary gear trains 20, 30 and the clutch C2, the brake B1, and the one-way clutch OWC can be the same as the transmission mode of A1. The rotation of the input shaft 3 is directly input to the planetary carrier P0 of the reduction planetary gear 40 comprising the second component B and the double pinion planetary gear via the clutch C2, and at the same time, the rotation from the planetary carrier P0 to the first via the clutch C4. Deceleration rotation of the input shaft 3 input to the component A through the ring gear R0 of the reduction planetary gear 40 with the sun gear S0 fixed is input to the fourth and first components D and A via the clutches C1 and C3. The first and second components A and B are braked by the brakes B2 and B1. Here, the input device section RE of the first and fourth constituent elements taking various forms includes a reduction planetary gear 40, clutches C1, C3 and C4, and a brake B2. The schematic diagram of FIG. 14 and FIG. 15 are obtained by inserting an A3 type structure into the blank input device unit RE of FIGS.

A3タイプの入力装置部REを多段自動変速装置前方に配した図15と図15の詳細を示す図16において、トルクコンバータケース1aとチャージングポンプを保持する保持部材2aが変速機ケース1bにボルト締めされ、ボス部が変速機ケース1b中央のL字型の側壁側に円筒状に延材され流体継ぎ手10及び入力軸3を軸支する保持部材2cを圧入する保持部材2bが保持部材2aにボルト締めされ、基本形態はA1と同じとなる。保持部材2bのボス部外周には保持部材2a側から順にクラッチC3、C4の2連クラッチと減速用遊星歯車40及びクラッチC1が配される。保持部材2bのボス部外周に配された減速用遊星歯車40は、保持部材2bのボス部外周にスプラインで固定されるサンギアS0(41)と、リティニングリング48で係止される側板47及びスラストニードルベアリングにより軸方向が保持されるリングギアR0(43)と、サンギアS0とリングギアR0との間を噛み合い連結するピニオン遊星歯車42a、42bのダブルピニオン遊星歯車を軸支する遊星キャリアP0からなり、遊星キャリアP0のサイド部材45aが保持部材2bのボス部外周に沿って延材され入力軸3と芯出しのための嵌め合い部を設けて連結部材X(46)として入力軸3にスプライン連結される。 15 and FIG. 16 showing details of FIG. 15 in which an A3-type input device RE is arranged in front of the multi-stage automatic transmission, a holding member 2a for holding the torque converter case 1a and the charging pump is bolted to the transmission case 1b. The holding member 2b is tightened and the holding member 2b is press-fitted into the holding member 2c that supports the fluid joint 10 and the input shaft 3 by extending the boss portion into a cylindrical shape on the L-shaped side wall in the center of the transmission case 1b. It is bolted and the basic form is the same as A1. On the outer periphery of the boss portion of the holding member 2b, a double clutch of clutches C3 and C4, a planetary gear 40 for reduction, and a clutch C1 are arranged in this order from the holding member 2a side.

Thus, the side member 45a of the planet carrier P0 extends along the outer periphery of the boss portion of the holding member 2b and is provided with a fitting portion for centering with the input shaft 3, and is splined to the input shaft 3 as a connecting member X (46).

The clutch drum 74 of the clutch C3 having a portion, the friction member 71 extending the outer periphery of the ring gear 43 toward the holding member 2a and being locked to the outer peripheral spline, and the friction member 71 are arranged alternately. 74, a friction member 72a locked to the inner cylindrical spline of the outer peripheral cylindrical portion 74 by the end plate 72b and the retaining ring 73, and a plurality of stud pins 75 at a fixed distance from the side wall of the clutch drum 74. And the clutch drum 84 of the clutch C4 provided on the inner circumferential direction inner side of the outer peripheral extending portion of the ring gear 43, and the clutch drum 84 An outer peripheral spline of the clutch hub 45c that is alternately disposed between the friction member 82a and the friction member 82a that are engaged with the cylindrical inner spline by the end plate 82b and the retaining ring 83 and welded to the side member 45b of the planet carrier P0. A hydraulic chamber is formed between the friction member 81 locked to the clutch drum 74 and the plurality of stud pins 75 between the clutch drums 74 and 84 so as to be movable in the axial direction and press the friction member 72c. A piston 76 that forms a hydraulic chamber between the piston 76 and presses the friction member 82a, and a centrifugal hydraulic canceller chamber is formed between the piston 85 and is locked to the cylindrical member 77 by the retaining ring 88. Between the piston 85 and the canceller plate 86, and the pistons 85 and 7 The clutch C3 is a ring gear R0, and the clutch C4 is a first configuration of the first and second planetary gear trains 20 and 30 via a planet carrier P0 and a clutch drum 74. It is responsible for fastening and releasing the connecting member Z (12) connected to one sun gear S1 forming the element.

尚、クラッチC3、C4のクラッチドラム74、84はリングギア43の外周延材部を挟んで円周方向に2段となるクラッチドラムとしてスタッドピン75により一体形成され、クラッチドラム74とピストン76との間及びピストン76とピストン85との間、ピストン85とキャンセラープレート86との間に形成される油圧室には保持部材2bのボス部外周から作動油が供給され油圧サーボを形成する。本案では2連クラッチC3、C4のクラッチドラム74、84をスタッドピン75で一体的に連結したが請求項6における2連クラッチC3、C4では本案に限らず別の方式でリングギアR0の外周延材部を挟んで円周方向に2段となるよう連結しピストン85、76及びキャンセラープレート86を重ね合わせて配してもよいとしている。 The clutch drums 74 and 84 of the clutches C3 and C4 are integrally formed by a stud pin 75 as a clutch drum having two stages in the circumferential direction across the outer peripheral extending portion of the ring gear 43. Hydraulic oil is supplied to the hydraulic chambers formed between the piston 76 and the piston 85 and between the piston 85 and the canceller plate 86 from the outer periphery of the boss portion of the holding member 2b. In this plan, the clutch drums 74 and 84 of the double clutches C3 and C4 are integrally connected by the stud pin 75. However, the double clutches C3 and C4 in claim 6 are not limited to this plan and may be extended to the outer periphery of the ring gear R0 by another method. It is said that the pistons 85 and 76 and the canceller plate 86 may be superposed and arranged so as to have two stages in the circumferential direction with the material part interposed therebetween.

クラッチC1はクラッチC3のクラッチドラム74と相対抗する開口部を有し連結部材Y(11)に溶着するクラッチドラム54と、リングギアR0の外周スプラインに係止される摩擦部材51と、摩擦部材51との間に交互に配されクラッチドラム54の外周円筒部内側スプラインにエンドプレート52bとリティニングリング53で係止される摩擦部材52aと、クラッチドラム54との間に油圧室を形成し摩擦部材52aを押圧するピストン56と、ピストン56との間に遠心油圧キャンセラー室を形成しリティニングリング59で連結部材Yに係止されるキャンセラープレート57と、ピストン56とキャンセラープレート57との間に配されピストン56を開放状態に戻すリターンスプリング58とからなっており、クラッチC1は遊星キャリアP0と第1、第2遊星歯車列20、30の第4構成要素を形成するサンギアS2と連結する連結部材Yとの締結及び開放をつかさどる。 The clutch C1 has an opening opposed to the clutch drum 74 of the clutch C3 and is welded to the connecting member Y (11), a friction member 51 locked to the outer peripheral spline of the ring gear R0, and a friction member Between the clutch drum 54 and the friction member 52a, which is alternately arranged between the friction plate 52 and the friction member 52a engaged with the end plate 52b and the retaining ring 53 on the inner peripheral spline of the clutch drum 54. A piston 56 that presses the member 52a, a centrifugal hydraulic canceller chamber formed between the piston 56 and a canceller plate 57 locked to the connecting member Y by a retaining ring 59, and between the piston 56 and the canceller plate 57 And a return spring 58 for returning the piston 56 to an open state, and the clutch C1. It governs the engagement and release of the coupling member Y which connects the sun gear S2 of forming a planet carrier P0 the fourth component of the first, second planetary gear train 20 and 30.

クラッチドラム54とピストン56との間及びピストン56とキャンセラープレート57との間に形成される油圧室には保持部材2bのボス部外周から減速用遊星歯車40の遊星キャリアP0のサイド部材45aと一体となる連結部材Xを介して作動油が供給され油圧サーボを形成する。尚、クラッチドラム54は入力軸3と一体としてスプライン連結される連結部材Xのスプラインボス上で軸受け4hにより回転自在に軸支され、クラッチC3のクラッチドラム74と第1遊星歯車列20のサンギアS1を連結する連結部材Zはクラッチドラム74の外周にスプライン連結されクラッチC1のクラッチドラム54の外周径方向外側を変速機ケース1b中央のL字型の側壁まで筒状に延材され側壁とクラッチドラム54の間を内周方向に延材しサンギアS1の延材部とスプライン連結するとともに連結部材Y上で軸受け4jにより回転自在に軸支される。 A hydraulic chamber formed between the clutch drum 54 and the piston 56 and between the piston 56 and the canceller plate 57 is integrated with the side member 45a of the planetary carrier P0 of the planetary gear 40 for reduction from the outer periphery of the boss portion of the holding member 2b. The hydraulic oil is supplied through the connecting member X to form a hydraulic servo. The clutch drum 54 is rotatably supported by a bearing 4h on a spline boss of a connecting member X that is splined together with the input shaft 3, and the clutch drum 74 of the clutch C3 and the sun gear S1 of the first planetary gear train 20 are supported. The connecting member Z is connected to the outer periphery of the clutch drum 74 by a spline, and the outer side in the outer peripheral radial direction of the clutch drum 54 of the clutch C1 extends in a cylindrical shape to the L-shaped side wall at the center of the transmission case 1b. 54 is extended in the inner circumferential direction and spline-connected to the extended portion of the sun gear S1, and is rotatably supported on the connecting member Y by the bearing 4j.

ブレーキB2は連結部材Zの外周スプラインの変速機ケース1b中央のL字型の側壁側に係止される摩擦部材101と、摩擦部材101との間に交互に配され変速機ケース1bの内周部に形成されたスプライン形状の複数の歯に係止される摩擦部材102aと、側壁側端に配されたエンドプレート102bと、保持部材2aに配されクラッチドラム74の外周径方向外側に延材して摩擦部材101、102aを押圧するピストン103と、リティニングリング106で保持部材2aに係止されるプレート105と、ピストン103を開放状態に戻すリターンスプリング104からなっており、第1、第2遊星歯車列20、30の第1構成要素を形成する一方のサンギアS1と連結する連結部材Zの制動及び開放をつかさどる。 The brake B2 is alternately disposed between the friction member 101 and the friction member 101 that are locked to the L-shaped side wall side in the center of the transmission case 1b of the outer peripheral spline of the connecting member Z, and the inner periphery of the transmission case 1b. Friction member 102a latched by a plurality of spline-shaped teeth formed in the section, end plate 102b disposed on the side wall side end, and extended to the outer circumferential radial direction of clutch drum 74 disposed on holding member 2a The piston 103 presses the friction members 101 and 102a, the plate 105 locked to the holding member 2a by the retaining ring 106, and the return spring 104 that returns the piston 103 to the open state. It controls the braking and release of the connecting member Z connected to one sun gear S1 forming the first component of the two planetary gear trains 20,30.

A3の変速形態は図14の速度線図で示されるように、前進8速のため前進1速段の減速比が大きくさらに前進8速段を小さくとれるよう減速用遊星歯車40の減速比を2前後とし、第1、第2遊星歯車列20、30の構成要素A、B、C、Dの位置関係を構成要素A、B間と構成要素B、C間の比率と構成要素C、D間と構成要素B、C間の比率を1.6前後としたものである。尚、一般車両では変速装置の変速比は変速装置からタイヤまでに配される終減速比も考慮し6〜0.6が適切とされる。したがって図14のようにZR1/ZS1=1.636、ZR2/ZS2=1.571、ZR0/ZS0=2.063にとれば前進1速段4.991から前進8速段0.621の前進1速を前進8速段の変速比で除したギアレンジが8.04となるA1、A2の変速形態以上のワイドなものが選定できる。 As shown in the speed diagram of FIG. 14, the speed change mode of A3 is that the reduction ratio of the planetary gear 40 for reduction is 2 so that the reduction ratio of the first forward speed is large and the eighth forward speed is smaller because of the eighth forward speed. The positional relationship between the constituent elements A, B, C and D of the first and second planetary gear trains 20 and 30 is the ratio between the constituent elements A and B and the constituent elements B and C and the constituent elements C and D. The ratio between the components B and C is about 1.6. In general vehicles, a transmission gear ratio of 6 to 0.6 is appropriate in consideration of a final reduction ratio arranged from the transmission to the tire. Therefore, as shown in FIG. 14, if ZR1 / ZS1 = 1.636, ZR2 / ZS2 = 1.571, ZR0 / ZS0 = 2.063, forward 1st speed 4.991 to forward 8th speed 0.621 forward 1 A gear range wider than the A1 and A2 gear shifting modes in which the gear range obtained by dividing the speed by the gear ratio of the eighth forward speed is 8.04 can be selected.

A3の変速形態における1st(前進1速段)から8th(前進8速段)及びRev(後進段)の作動と変速比を示す図14において、A2の前進6速の変速形態にクラッチC4を介して入力軸3の非減速回転を構成要素Aに入力したもので、クラッチ、ブレーキの締結要素はC1、C4とC2、C4の締結による2種の変速段が追加される。したがって、締結要素はC1、C4の締結が前進4速段となりC2、C4の締結が前進6速段となる。つまり、A2の変速形態の前進4速段は前進5速段となり、前進5,6速段が前進7、8速段となる。尚、B1、C4の締結でも後進の高速段が得られるが、通常車両では利用する必要がないためここでは記さなかった。 In FIG. 14 showing the operation and the gear ratio from 1st (first forward speed) to 8th (eight forward speed) and Rev (reverse speed) in the speed change mode of A3, the shift speed mode of A2 is changed to 6th speed forward via the clutch C4. Thus, the non-decelerated rotation of the input shaft 3 is input to the component A, and the clutch and brake engaging elements are added with two types of gears by engaging C1, C4 and C2, C4. Therefore, the fastening elements C1 and C4 are fastened to the fourth forward speed, and C2 and C4 are fastened to the sixth forward speed. That is, the fourth forward speed of the A2 speed change mode is the fifth forward speed, and the fifth and sixth forward speeds are the seventh and eighth forward speeds. In addition, although the reverse high-speed stage is obtained even if B1 and C4 are fastened, it is not described here because it is not necessary to use it in a normal vehicle.

A3の変速形態の特色として構成要素Aの同一要素に入力軸3の減速回転と非減速回転の2種がクラッチC3、C4を介して入力する点にある。構成要素Aに2種の回転が同時に入力することは有得ないことより、クラッチドラムを共通の出力としピストンを重ね合わせた2連クラッチC3、C4の適用が考えられる。本発明ではリングギア43の外周延材部を挟んで円周方向に2段となるクラッチドラムとしたことでより一層のコンパクト化を実現している。ピストンを重ね合わせる方式では遠心油圧キャンセラー室とリターンスプリングが共用化できシンプル・コンパクトとなるが、これにとどまらず変速特性が良くなる利点がある。前進3速段と4速段及び前進6速段と7速段の変速ではクラッチC3とクラッチC4の切り換えで変速が行われる。クラッチC4の油圧室はクラッチC4のピストン85とクラッチC3のピストン76とで形成されるためクラッチC4の油圧室の作動油圧が両ピストンに作用する。つまりクラッチC4の締結力を加えるようピストン85に作用する作動油圧はクラッチC3の締結力を減少するようピストン76に作用する。クラッチC3を開放してクラッチC4を締結する場合クラッチC4の油圧を上げることで自動的にクラッチC3を開放し、クラッチC4を開放してクラッチC3を締結する場合クラッチC4の油圧を下げることで自動的にクラッチC3を締結してクラッチC3とC4を切り換えて変速する前進3速と4速の間及び前進6速と7速の間のスムースな変速制御が可能となる。この変速制御特性は本件発明者が特願2006−180590の図29で詳細説明をしている。 A characteristic of the speed change mode of A3 is that two types of rotation of the input shaft 3, decelerated rotation and non-decelerated rotation, are input to the same element of the component A via the clutches C3 and C4. Since two types of rotation cannot be input to the component A at the same time, it is conceivable to apply the double clutches C3 and C4 in which the clutch drum is used as a common output and the pistons are overlapped. In the present invention, the clutch drum having two stages in the circumferential direction with the outer peripheral extending portion of the ring gear 43 interposed therebetween realizes further downsizing. The method of superposing pistons makes the centrifugal hydraulic canceller chamber and return spring shared, making it simple and compact, but there is an advantage that the speed change characteristics are not limited to this. In the forward third speed and the fourth speed and the forward sixth speed and the seventh speed, the shift is performed by switching between the clutch C3 and the clutch C4. Since the hydraulic chamber of the clutch C4 is formed by the piston 85 of the clutch C4 and the piston 76 of the clutch C3, the hydraulic pressure in the hydraulic chamber of the clutch C4 acts on both pistons. That is, the hydraulic pressure acting on the piston 85 so as to apply the fastening force of the clutch C4 acts on the piston 76 so as to reduce the fastening force of the clutch C3. When the clutch C3 is released and the clutch C4 is engaged, the clutch C3 is automatically released by increasing the hydraulic pressure of the clutch C4. When the clutch C4 is released and the clutch C3 is engaged, the clutch C4 is automatically decreased by lowering the hydraulic pressure. Thus, smooth shift control between the forward 3rd speed and the 4th speed and the forward 6th speed and the 7th speed in which the clutch C3 is engaged and the clutches C3 and C4 are switched can be performed. This shift control characteristic is described in detail by the present inventor in FIG. 29 of Japanese Patent Application No. 2006-180590.

A3の変速形態において、減速比が大きくとれる前進1速段では減速用遊星歯車40で入力トルクが1.94倍に増幅され第2遊星歯車列30のサンギアS2に加わる。しかし、A1の変速形態ではZR2/ZS2=2.25に対しA3の変速形態ではZR2/ZS2=1.571であるためリングギアの径を同じとすればサンギアS2の径は2.25/1.571=1.43倍となる。しかし、図23に示すようにピニオン遊星歯車の個数をA1の変速形態の図21に示す4個の1.5倍の6個としているので強度的には1.43×1.5=2.14と入力トルクが1.94倍となってもA1の変速形態より有利になる。第1遊星歯車列20のサンギアS1には減速用遊星歯車40で入力トルクが1.94倍に増幅されさらに第2遊星歯車列30で約1.571倍の1.94×1.571=3.05倍に入力トルクが増幅される。2.25倍に入力トルクが増幅されサンギアS1に加わるA1の変速形態より1.35倍強度が足りなくなる。ピニオン遊星歯車の個数を8個にすれば強度的には同等となるが、ギアレンジが8.04と十分牽引力が確保できる大きさのためトルクコンバータによるトルク増幅が必要なくなる。減速用遊星歯車40で入力トルクが1.94倍に増幅されるためクラッチC1、ブレーキB1のトルク容量も増やさねばならないが、トルクコンバータによる通常1.8倍前後のストールトルク比特性を持つトルク増幅をなくすと容量も押さえることができる。 In the speed change mode of A3, at the first forward speed where the reduction ratio is large, the input torque is amplified 1.94 times by the reduction planetary gear 40 and applied to the sun gear S2 of the second planetary gear train 30. However, ZR2 / ZS2 = 2.25 in the A1 speed change mode and ZR2 / ZS2 = 1.571 in the A3 speed change mode. Therefore, if the diameter of the ring gear is the same, the diameter of the sun gear S2 is 2.25 / 1. .571 = 1.43 times. However, as shown in FIG. 23, the number of pinion planetary gears is six times 1.5 times the four shown in FIG. 21 of the A1 speed change mode, so that 1.43 × 1.5 = 2. 14 and an input torque of 1.94 times are more advantageous than the A1 speed change mode. The input torque of the sun gear S1 of the first planetary gear train 20 is amplified 1.94 times by the planetary gear 40 for reduction, and further 1.94 × 1.571 = 3, which is about 1.571 times greater by the second planetary gear train 30. The input torque is amplified by .05 times. The input torque is amplified 2.25 times, and the strength of 1.35 times is less than that of the A1 speed change mode applied to the sun gear S1. If the number of pinion planetary gears is eight, the strength is equivalent, but the gear range is 8.04, which is a size that can secure a sufficient tractive force, so that torque amplification by a torque converter is not necessary. The torque capacity of the clutch C1 and the brake B1 must be increased because the input torque is amplified 1.94 times by the reduction planetary gear 40. However, the torque amplification is usually about 1.8 times by the torque converter and has a stall torque ratio characteristic. If you eliminate, you can reduce the capacity.

そこで、図15に示すようにトルクコンバータに代えてインペラとタービンの2個の羽根車からなるトルク増幅のない流体継ぎ手10を流体伝導装置に用いる。流体継ぎ手はトルクコンバータにおけるトルク増幅のためのリアクタ羽根車及びワンウェイクラッチがないためその分軸方向が短縮できる。加えてリアクタ羽根車によるインペラ羽根車への入力トルクの減少作用が働かないため羽根車のトーラス断面も小さく出来、重量及びコスト面で有利となる。円周方向に2段となるクラッチドラムとピストンを軸方向に重ね合わせてコンパクト化とコストダウンを図り前進8速段としたが、前進6速段と比べクラッチC4を追加したため軸方向の長さとコスト及び重量面では不利となる。当然クラッチ4に繋がる第1構成要素のイナーシャも増え、変速に際しては変速装置における回転部位のイナーシャを吸収する必要があるため、各クラッチ及びブレーキの容量も前進6速に比べ大きくしなければならない。しかし、流体継ぎ手では入力軸3と一体となるタービンのトーラス断面が小さくできタービンのイナーシャが小さくなるためトルクコンバータを用いる前進6速と比べ各クラッチ及びブレーキのイナーシャ吸収容量を大きくする必要はない。流体継ぎ手10を流体伝導装置に用いることで軸方向の長さ及び重量は前進6速段より有利となりコストは油圧制御部のみ高くなるだけで済む。当然ギアレンジが8.04と大きく各変速段の段間差も小さくなるため発進以外のフルロックアップによる原動機直結も可能となり燃費の向上が図れる。 Therefore, as shown in FIG. 15, instead of the torque converter, a fluid joint 10 having two torque impellers and an impeller without a torque amplification is used for the fluid conduction device. Since the fluid coupling does not have a reactor impeller and a one-way clutch for torque amplification in the torque converter, its axial direction can be shortened. In addition, since the reactor impeller does not reduce the input torque to the impeller impeller, the torus cross section of the impeller can be made small, which is advantageous in terms of weight and cost. The clutch drum and piston, which have two stages in the circumferential direction, are overlapped in the axial direction to achieve compactness and cost reduction to achieve the eighth forward speed. However, compared to the sixth forward speed, the clutch C4 is added, so the axial length This is disadvantageous in terms of cost and weight. Naturally, the inertia of the first component connected to the clutch 4 also increases, and it is necessary to absorb the inertia of the rotating part of the transmission when shifting, and therefore the capacity of each clutch and brake must be larger than that of the sixth forward speed. However, in the fluid joint, the torus cross section of the turbine integrated with the input shaft 3 can be reduced, and the inertia of the turbine can be reduced. Therefore, it is not necessary to increase the inertia absorption capacity of each clutch and brake compared to the sixth forward speed using the torque converter. By using the fluid joint 10 in the fluid transmission device, the axial length and weight are more advantageous than the sixth forward speed, and the cost is only increased for the hydraulic control unit. Naturally, the gear range is as large as 8.04, and the difference between the gears is also small, so that it is possible to directly connect the prime mover by full lock-up other than starting, and the fuel efficiency can be improved.

A2の変速形態の構成要素Dに、減速回転に加え非減速回転を入力して前進10速とした特許文献と同じ変速形態をA4とし図17から図19及び図25に示す。図17の速度線図の構成要素A、B、C、Dは変速形態をA1とする図5と同じ第1、第2遊星歯車列20、30の構成要素である。したがって、第1、第2遊星歯車列20、30とクラッチC2、ブレーキB1及びワンウェイクラッチOWCの配置はA1の変速形態と同じくできる。入力軸3の回転は直接クラッチC2を介して第2構成要素B及びダブルピニオン遊星歯車からなる減速用遊星歯車40の遊星キャリアP0に入力されると同時に遊星キャリアP0からクラッチC4を介して第4構成要素Dに入力され、サンギアS0を固定した減速用遊星歯車40のリングギアR0を介した入力軸3の減速回転はクラッチC1、C3を介して第4、第1構成要素D、Aに入力され、第1、第2構成要素A,BはブレーキB2、B1で制動される。ここで、多様な形態をとる第1と第4構成要素の入力装置部REは減速用遊星歯車40と、クラッチC1、C3、C4と、ブレーキB2とからなっている。図17の模式図及び図18は図1、図3の空白となる入力装置部REにA4タイプの構造を挿入したものである。

The rotation of the input shaft 3 is directly input to the planetary carrier P0 of the reduction planetary gear 40 comprising the second component B and the double pinion planetary gear via the clutch C2, and at the same time, the rotation from the planetary carrier P0 to the fourth via the clutch C4.

Therefore, as in the gear shift mode A3, the gear range obtained by dividing the first forward speed from the first forward speed 4.991 to the forward 10th speed stage 0.621 by the reduction ratio of the forward 10th speed stage is 8.04. Can be selected.

A4の変速形態における1st(前進1速段)から10th(前進10速段)及びRev(後進段)の作動と減速比を示す図17において、A2の前進6速の変速形態にクラッチC4を介して入力軸3の非減速回転を構成要素Dに入力したもので、クラッチ、ブレーキの締結要素はC4、B1とC4、B2及びC4、C3さらにC4、C2の締結による4種の変速段が追加される。したがって、締結要素はC4、B1の締結が前進3速段となりC4、B2の締結が前進5速段となりC4、C3締結が前進7速段となりC4、C2の締結が前進8速段となる。つまり、A2の変速形態の前進3速段が前進4速段となり、前進4速段が前進6速段となり、前進5,6速段が前進9、10速段となる。また、A4の変速形態はA1とA2の変速形態を合わせたものであり、両方の変速形態の特性を有する。 In FIG. 17 showing the operation and the reduction ratio from 1st (first forward speed) to 10th (10th forward speed) and Rev (reverse speed) in the A4 speed change mode, the A6 speed change mode of 6th speed is connected via the clutch C4. The non-decelerated rotation of the input shaft 3 is input to the component D, and the clutch and brake engagement elements are C4, B1 and C4, B2 and C4, C3, and C4 and C2 are further engaged. Is done. Therefore, the fastening elements C4 and B1 are the third forward speed, C4 and B2 are the fifth forward speed, C4 and C3 are the seventh forward speed, and C4 and C2 are the eighth forward speed. In other words, the third forward speed of the A2 speed change mode is the fourth forward speed, the fourth forward speed is the sixth forward speed, and the fifth and sixth forward stages are the forward 9, 10th speed stages. The A4 speed change mode is a combination of the A1 and A2 speed change modes, and has characteristics of both speed change modes.

通常変速は変速特性悪化を避けるため2個の締結要素の1個を切り換えることで行われる。図17のA〜Eの変速パターンを示した表は、クラッチC1から始まるA2の変速形態をA1の変速形態であるクラッチC4に切り換えるその変速段位置を変えたものである。クラッチC1は1st、2nd、4th、6thのA2変速形態の4変速段で締結し、クラッチC4は3rd、5th、7th、8thのA1変速形態の4変速段で締結しそれぞれ締結要素の1個を切り換えることで変速が行われる。変速パターンAではA2変速形態の1stからA1変速形態の3rd、5th、7th、8thに変速し、変速パターンBではA2変速形態の1st、2nd、4thからA1変速形態の6th、8thに変速し、変速パターンCではA2変速形態の1st、2ndからA1変速形態の5th、7th、8thに変速し、変速パターンDではA2変速形態の1st、2nd、4thからA1変速形態の7th、8thに変速し、変速パターンEでは3rdの締結要素クラッチC4とブレーキB1のブレーキB1の代わりに自動的に切り換わり変速特性のよいワンウェイクラッチOWCを用いたものを変速パターンAに追加し、A1、A2変速形態共通の9th、10thを含めて1stの変速比を10thの変速比で割った値が8.04とワイドになる前進7速段又は8速段とした。 The normal shift is performed by switching one of the two fastening elements to avoid deterioration of the shift characteristic. The table showing the shift patterns A to E in FIG. 17 is obtained by changing the shift position for switching the shift mode A2 starting from the clutch C1 to the clutch C4 which is the shift mode A1. Clutch C1 is engaged at 4th gear stage of 1st, 2nd, 4th, 6th A2 speed change mode, and clutch C4 is engaged at 4th speed stage of 3rd, 5th, 7th, 8th A1 speed change mode, and each one of the engaging elements is engaged. Shifting is performed by switching. In the shift pattern A, the gear shifts from 1st in the A2 shift mode to 3rd, 5th, 7th, 8th in the A1 shift mode, and in the shift pattern B, shifts from 1st, 2nd, 4th in the A2 shift mode to 6th, 8th in the A1 shift mode, In the shift pattern C, the A2 shift mode 1st, 2nd shifts to the A1 shift mode 5th, 7th, 8th, and in the shift pattern D, the A2 shift mode 1st, 2nd, 4th shifts to the A1 shift mode 7th, 8th, In the shift pattern E, a one-way clutch OWC having a good shift characteristic is automatically added instead of the 3rd engagement element clutch C4 and the brake B1 of the brake B1, and is added to the shift pattern A. The value obtained by dividing the 1st transmission ratio including 9th and 10th by the 10th transmission ratio is 8.04. It was the seventh forward speed or 8-speed stage to become a de.

A4の変速形態の特色として構成要素Dの同一要素に入力軸3の減速回転と非減速回転の2種がクラッチC1、C4を介して入力する点にある。構成要素Dに2種の回転が同時に入力することは有得ないことより、クラッチドラムを共通の出力としピストンを重ね合わせた2連クラッチC1、C4の適用が考えられる。前項で述べたAからEの変速パターンはクラッチC1とC4をどの変速段で切り換えるかにより5種類のパターンが生じるもので、クラッチC1とC4の切り換え以外の変速はA1、A2の変速形態と同じとなる。クラッチC1とC4の切り換えはA3の変速形態で述べたクラッチC3とC4の切り換えと同じく独立したクラッチの切り換え制御より簡単でスムースな変速が可能となる。 A feature of the speed change mode of A4 is that two types of rotation of the input shaft 3, reduced speed rotation and non-reduced speed rotation, are input to the same element of the component D via the clutches C1 and C4. Since two kinds of rotations cannot be input to the component D at the same time, it is conceivable to apply the double clutches C1 and C4 in which the clutch drum is used as a common output and the pistons are overlapped. The shift patterns from A to E described in the previous section are generated in five patterns depending on the shift speed at which the clutches C1 and C4 are switched. Shifts other than the switching between the clutches C1 and C4 are the same as the shift modes of the A1 and A2. It becomes. The switching of the clutches C1 and C4 enables a simpler and smoother shifting than the independent clutch switching control similar to the switching of the clutches C3 and C4 described in the shifting mode of A3.

A4の変速形態において、減速比が大きくとれる前進1速段では減速用遊星歯車40で入力トルクが1.94倍に増幅され第2遊星歯車列30のサンギアS2に加わり、A3の変速形態で述べた如くA3の変速形態と同じ力が各歯車に作用するため説明は省略する。但しクラッチC1からC4に切り換わった後は動力が減速用遊星歯車40を通過しないため各歯車に作用する力が減少する。加えてA1の変速形態ではZR2/ZS2=2.25に対しA4の変速形態ではZR2/ZS2=1.571であるためリングギアの径を同じとすればサンギアS2の径は2.25/1.571=1.43倍となりA1の変速形態より1.43倍強度的に有利となる。A3及びA4の変速形態における変速比は類似しているがA4の変速形態の方が強度的には有利となる。尚、ギアレンジが8.04と十分牽引力が確保できる大きさのためトルクコンバータによるトルク増幅が必要なくなる点A3の変速形態と同じでありトルクコンバータを用いる必要もなくなる。 In the A4 speed change mode, at the first forward speed with a large reduction ratio, the input planetary gear 40 amplifies the input torque by 1.94 times and is added to the sun gear S2 of the second planetary gear train 30, and is described in the A3 speed change mode. As described above, since the same force as that in the A3 speed change mode acts on each gear, the description is omitted. However, since the power does not pass through the reduction planetary gear 40 after switching from the clutch C1 to C4, the force acting on each gear decreases. In addition, ZR2 / ZS2 = 2.25 in the A1 speed change mode and ZR2 / ZS2 = 1.571 in the A4 speed change mode, so if the ring gear diameter is the same, the diameter of the sun gear S2 is 2.25 / 1. .571 = 1.43 times, which is 1.43 times stronger than the A1 speed change mode. The transmission ratios in the A3 and A4 transmission modes are similar, but the A4 transmission mode is advantageous in terms of strength. The gear range is 8.04, which is a size that can secure a sufficient traction force, and therefore, it is the same as the speed change form of point A3 in which torque amplification by the torque converter is not necessary, and it is not necessary to use a torque converter.

そこで、図18に示すようにトルクコンバータに代えてインペラとタービンの2個の羽根車からなるトルク増幅のない流体継ぎ手10を流体伝導装置に用いることで、軸方向の長さと重量面でA1、A2の前進6速段の変速形態より有利にすることができる。又、各クラッチ及びブレーキの変速時のイナーシャ吸収容量もA3の変速形態と同じで大きくする必要はない。当然ギアレンジが8.04と大きく各変速段の段間差も小さくなるため発進以外のフルロックアップによる原動機直結も可能となり燃費の向上が図れる。 Therefore, as shown in FIG. 18, instead of the torque converter, a fluid coupling 10 including two impellers of an impeller and a turbine without torque amplification is used in the fluid conduction device, so that A1 in terms of axial length and weight, This can be more advantageous than the A6 forward sixth speed. Further, the inertia absorption capacity at the time of shifting of each clutch and brake is the same as the shifting mode of A3 and does not need to be increased. Naturally, the gear range is as large as 8.04, and the difference between the gears is also small, so that it is possible to directly connect the prime mover by full lock-up other than starting, and the fuel efficiency can be improved.
