 一般に、エンジンが車両の前側に配置された前輪駆動車両では、エンジンの出力軸が車両の幅方向に沿うように配置される。M/Tの入力軸は、クラッチを介してエンジンの出力軸と同軸上に配置されて接続される。このため、M/Tは、M/Tの入力軸が車両の幅方向に沿うようにクラッチを介してエンジン付近に配置される。即ち、エンジン・クラッチ・M/Tのアッセンブリは、車両のエンジンルーム内において比較的狭い左右のサイドフレーム間に配置される。従って、M/Tの軸方向の全長を短縮することが望まれる。 Generally, in a front-wheel drive vehicle in which the engine is disposed on the front side of the vehicle, the engine output shaft is disposed along the width direction of the vehicle. The input shaft of the M / T is disposed coaxially with and connected to the output shaft of the engine via a clutch. For this reason, M / T is arrange | positioned in the engine vicinity through a clutch so that the input shaft of M / T may follow the width direction of a vehicle. That is, the engine / clutch / M / T assembly is disposed between the left and right side frames which are relatively narrow in the engine room of the vehicle. Therefore, it is desired to shorten the total length of the M / T in the axial direction.
 更には、近年、車両のコンパクト化、及び、車両の衝突安全性の向上等を目的としてサイドフレームの大型化の傾向がある。また、動力源としてエンジンと電動モータとを備えた所謂ハイブリッド車両も増加している。これらの結果、M/Tの搭載スペースは更に狭くなってきている。即ち、M/Tの軸方向の全長の短縮化がますます望まれる。 Furthermore, in recent years, there is a tendency for the size of the side frame to be increased in order to make the vehicle compact and improve the collision safety of the vehicle. In addition, so-called hybrid vehicles including an engine and an electric motor as power sources are also increasing. As a result, the mounting space for the M / T is further narrowed. That is, it is increasingly desired to shorten the overall length of the M / T in the axial direction.
 以下、本発明においては、説明の便宜上、軸に相対回転可能に設けられ、その軸と係脱可能に連結されるギヤを遊転ギヤと定義し、一つのスリーブに係合可能な一対の遊転ギヤを、「ギヤセット」と称することにする。 Hereinafter, in the present invention, for convenience of explanation, a gear that is provided so as to be rotatable relative to a shaft and is detachably connected to the shaft is defined as an idler gear, and a pair of idlers that can be engaged with a single sleeve. The rolling gear will be referred to as “gear set”.
 図9に示す従来の六速M/Tでは、本発明において定義された遊転ギヤに相当する前進用の六つの被動ギヤG1o、G2o、G3o、G4o、G5o、G6oが、二本の中間軸に振り分けられて配置されている。この結果、特に第一中間軸A1には、二つのギヤセット(即ち、四つの被動ギヤG1o、G2o、G3o、G4o)が配置されている。このように一つの中間軸に配置される被動ギヤの個数が多いことが、このM/Tの軸方向長さが長くなる大きな要因の一つになっていた。軸方向長さを短縮化できる車両用手動変速機の到来が望まれている。 In the conventional six-speed M / T shown in FIG. 9, six driven gears G1o, G2o, G3o, G4o, G5o, and G6o corresponding to the idle gears defined in the present invention have two intermediate shafts. It is distributed and arranged. As a result, two gear sets (that is, four driven gears G1o, G2o, G3o, G4o) are arranged on the first intermediate shaft A1. Thus, the large number of driven gears arranged on one intermediate shaft is one of the major factors that increase the axial length of the M / T. The arrival of a manual transmission for vehicles that can shorten the axial length is desired.
 本発明は、入力軸、出力軸、及び、複数の中間軸を備え、軸方向長さを短縮化できる車両用手動変速機を提供することを目的とする。 An object of the present invention is to provide a vehicle manual transmission that includes an input shaft, an output shaft, and a plurality of intermediate shafts, and that can reduce the axial length.

 上記のように構成された実施形態に係る車両用手動変速機M/Tにおいて、前進用の六つの被動ギヤGo1、Go2、Go3、Go4、Go5、Go6と、後進用の変速段の被動ギヤGr2と、は、本発明において定義された遊転ギヤである。この七個の遊転ギヤは、三本の中間軸A1、A2、A3に振り分けられて配置される。具体的には、第一中間軸A1には、被動ギヤGo5と被動ギヤGo6と後進用の変速段の被動ギヤGr2との遊転ギヤ三個が振り分けられている。また、第二中間軸A2には、被動ギヤGo3と被動ギヤGo4との遊転ギヤ二個が振り分けられている。また、第三中間軸A3には、被動ギヤGo1と被動ギヤGo2との遊転ギヤ二個が振り分けられている。 In the vehicle manual transmission M / T according to the embodiment configured as described above, the six driven gears Go1, Go2, Go3, Go4, Go5, Go6 for forward movement, and the driven gear Gr2 for the reverse gear stage. Are idle gears as defined in the present invention. The seven idler gears are distributed and arranged on three intermediate shafts A1, A2, and A3. Specifically, three idle gears of a driven gear Go5, a driven gear Go6, and a reverse gear driven gear Gr2 are distributed to the first intermediate shaft A1. In addition, two idle gears, a driven gear Go3 and a driven gear Go4, are distributed to the second intermediate shaft A2. In addition, two free-wheeling gears of a driven gear Go1 and a driven gear Go2 are distributed to the third intermediate shaft A3.
 従って、本実施形態に係る車両用手動変速機M/Tは、背景技術の欄で述べた従来のM/T(前進用の六つの被動ギヤが二本の中間軸に振り分けられて配置される。図9を参照)と比べて、各中間軸当たりに振り分けられる遊転ギヤの最大個数を減らすことができる。具体的には、図9に示す従来のM/Tでは、第一中間軸A1にて二つの「ギヤセット」(即ち、4個の遊転ギヤ)が配置されているのに対し、本第実施形態の車両用手動変速機M/Tでは、遊転ギヤの最大個数の配置が、第一中間軸A1において、遊転ギヤの最大個数一つ半の「ギヤセット」(即ち、三個の遊転ギヤ)となる。この結果、本実施形態に係る車両用手動変速機M/Tは、従来と比べて、車両用手動変速機の軸方向長さをより一層短くすることができる。 Therefore, the vehicle manual transmission M / T according to the present embodiment is arranged with the conventional M / T (six driven gears for forward movement distributed to the two intermediate shafts described in the background art section. 9 (see FIG. 9), the maximum number of idle gears assigned to each intermediate shaft can be reduced. Specifically, in the conventional M / T shown in FIG. 9, two “gear sets” (that is, four idle gears) are arranged on the first intermediate shaft A1, whereas this first embodiment In the vehicle manual transmission M / T having the configuration, the arrangement of the maximum number of idle gears in the first intermediate shaft A1 is a “gear set” (ie, three idle gears) of the maximum number of idle gears. Rolling gear). As a result, the vehicular manual transmission M / T according to the present embodiment can further reduce the axial length of the vehicular manual transmission compared to the related art.
 また、上記実施形態の車両用手動変速機M/Tでは、後進用の変速段の被動ギヤGr2と常時噛合する後進用の変速段の駆動ギヤGr1は、一速の被動ギヤGo1(=遊転ギヤ)と一体固定された例を示す。しかしながら、この例に限ることなく、後進用の変速段の被動ギヤGr2と常時噛合する後進用の変速段の駆動ギヤGr1は、二速の被動ギヤGo2(=遊転ギヤ)と一体固定する変更も可能であることは明らかである。この場合、後進用の変速段を成立するためには、同様にスリーブS4が後進用の変速段の被動ギヤGr2の接続状態とされ、その他のスリーブS1、S2、S3は非接続状態とされる。これにより、後進時において、車両用手動変速機M/T内において、(入力軸Ai→二速の駆動ギヤGi2→二速の被動ギヤGo2→後進用の変速段の駆動ギヤGr1→後進用の変速段の被動ギヤGr2→第十一連結ピース42→スリーブS4→第十連結ピース41→第一中間軸A1→第一最終駆動ギヤGfi1→最終被動ギヤGfo→出力軸Ao)という動力伝達系統が形成される。 Further, in the vehicle manual transmission M / T of the above embodiment, the drive gear Gr1 for the reverse gear that is always meshed with the driven gear Gr2 for the reverse gear is the first-speed driven gear Go1 (= idling). An example of being fixed integrally with a gear) is shown. However, the present invention is not limited to this example, and the drive gear Gr1 for the reverse gear that is always meshed with the driven gear Gr2 for the reverse gear is changed to be fixed integrally with the second-speed driven gear Go2 (= idling gear). Obviously, it is possible. In this case, in order to establish the reverse gear, the sleeve S4 is similarly connected to the driven gear Gr2 of the reverse gear, and the other sleeves S1, S2, S3 are not connected. . As a result, during reverse travel, in the vehicle manual transmission M / T, (input shaft Ai → second speed drive gear Gi2 → second speed driven gear Go2 → reverse gear drive gear Gr1 → reverse gear The power transmission system of the gear driven gear Gr2 → the eleventh connecting piece 42 → the sleeve S4 → the tenth connecting piece 41 → the first intermediate shaft A1 → the first final drive gear Gfi1 → the final driven gear Gfo → the output shaft Ao). It is formed.
 また、上記実施形態の車両用手動変速機M/Tでは、第三グループの変速段(一速及び二速)が、第一グループの変速段(五速、六速)及び第二グループの変速段(三速、四速)と比べて低速側の変速段に設定されている。加えて、上述のように、第三グループの変速段のうちの一つの変速段のギヤ(一速の被動ギヤGo1又は二速の被動ギヤGo2)が後進用の変速段(リバース)に使用される。従って、後進用の変速段における減速比を低速側(ローギヤード)にすることができ、低速での後進走行時に必要な大きなトルクを確保することができる。 In the vehicle manual transmission M / T according to the above-described embodiment, the third group shift speeds (first speed and second speed) are the first group shift speeds (fifth speed, sixth speed) and the second group shift speeds. The speed is set to a lower speed than that of the third speed (fourth speed). In addition, as described above, the gear of one of the third group of gears (first-speed driven gear Go1 or second-speed driven gear Go2) is used for the reverse gear (reverse). The Therefore, the reduction gear ratio in the reverse gear can be set to the low speed side (low geared), and a large torque required for reverse travel at low speed can be secured.
 なお、本発明は、前述の実施形態に限定されることはなく、本発明の範囲内において種々の態様を採用することができる。上記の実施形態では、前進用に六つ変速段(一速~六速)、後進用に一つの変速段(リバース)を備えた車両用手動変速機M/Tの例を説明したが、しかしながら、これに代えて、変速段を増やしたり、あるいは、変速段を減らす態様が可能であることは明らかである。 In addition, this invention is not limited to the above-mentioned embodiment, A various aspect can be employ | adopted within the scope of the present invention. In the above embodiment, the example of the vehicle manual transmission M / T provided with six shift speeds (first speed to sixth speed) for forward movement and one shift speed (reverse) for backward movement has been described. Instead of this, it is obvious that a mode in which the gear stage is increased or the gear stage is decreased is possible.
