上記文献の変速機の操作装置は、作動部からの衝撃が弾性部材によって吸収され、第２伝動部材から第１伝動部材に伝わることが抑制される一方で、衝撃を吸収した弾性部材がその後に振動し、この振動によって、手動でのシフト操作又はシフト操作時のフィーリングの悪化や、アクチュエータの電力制御の悪化や、制御性の悪化等を招く場合がある。   In the transmission operating device of the above-mentioned document, the elastic member that absorbs the impact from the operating portion and is suppressed from being transmitted from the second transmission member to the first transmission member is used. The vibration may cause manual shift operation or feeling during a shift operation, power control of the actuator, controllability, and the like.

本発明は、弾性部材の振動を効率的に防止する変速機用シフトダンパ構造を提供することを課題とする。   It is an object of the present invention to provide a transmission shift damper structure that efficiently prevents vibration of an elastic member.

上記課題を解決するため、手動又はアクチュエータによるシフト操作又はセレクト操作の操作力が伝動されて回転する第１伝動部材と、前記第１伝動部材と異なる位置に配置され且つ前記第１伝動部材と相対回転可能に設けられる第２伝動部材と、前記第１伝動部材と第２伝動部材との間に形成された収容室に収容され且つ前記第１伝動部材の動力を前記第２伝動部材に伝動して該第２伝動部材の回転を許容する弾性部材と、第２伝動部材の回転によってシフト作動又はセレクト作動する作動部とを備え、前記収容室には、前記弾性部材の作動を規制する流体が充填され、該流体が前記収容室へ流入及び前記収容室から流出することを許容する選択機構を備えることを特徴とする。   In order to solve the above-mentioned problem, a first transmission member that is rotated by transmission of an operation force of manual or actuator shift operation or selection operation is disposed at a position different from that of the first transmission member and relative to the first transmission member. A second transmission member provided rotatably and a storage chamber formed between the first transmission member and the second transmission member and transmitting the power of the first transmission member to the second transmission member. An elastic member that allows rotation of the second transmission member, and an operation unit that performs a shift operation or a selection operation by the rotation of the second transmission member, and fluid that regulates the operation of the elastic member is contained in the storage chamber. A selection mechanism that is filled and allows the fluid to flow into and out of the storage chamber is provided.

前記収容室は、前記第１伝動部材及び第２伝動部材によって形成されたものとしてもよい。   The storage chamber may be formed by the first transmission member and the second transmission member.

前記選択機構は、前記第１伝動部材と前記第２伝動部材との間に回転差が生じた場合、前記収容室内からの流体の流出及び該収容室内への流体の流入を規制し、前記第１伝動部材と前記第２伝動部材との間に回転差が生じていない場合には該規制を解除するものとしてもよい。   The selection mechanism regulates the outflow of fluid from the storage chamber and the inflow of fluid into the storage chamber when a rotational difference is generated between the first transmission member and the second transmission member, When there is no rotational difference between the first transmission member and the second transmission member, the restriction may be released.

前記流体が溜る流体溜り部が形成され、前記流体溜り部に溜った流体が前記収容室に供給されるものとしてもよい。   A fluid reservoir for storing the fluid may be formed, and the fluid stored in the fluid reservoir may be supplied to the storage chamber.

収容室に充填された流体によって、弾性部材の作動を規制することができるため、作動部からの衝撃を弾性部材によって吸収させた場合でも、該弾性部材の振動を効率的に抑制することが可能である。これによって、手動でのシフト操作又はシフト操作時のフィーリングの悪化や、アクチュエータの電力制御の悪化や、制御性の悪化等を効率的に防止できる。   Since the operation of the elastic member can be regulated by the fluid filled in the storage chamber, it is possible to efficiently suppress the vibration of the elastic member even when the impact from the operating portion is absorbed by the elastic member. It is. As a result, it is possible to efficiently prevent manual shift operation or feeling deterioration during shift operation, actuator power control deterioration, controllability deterioration, and the like.

The operating device shown in FIG. 1 includes a shift and select shaft 1, a selection actuator 2 that performs a selection operation by sliding the shift and select shaft 1 in the axial direction, and the shift and select shaft 1 about its axis. And a shift actuator 3 that performs a shift operation by rotating the lens to the right.

セレクト操作によって、シフトアンドセレクトシャフト１に装着されたインナーレバー（作動部）４が該シフトアンドセレクトシャフト１と共に軸方向に一体でスライド作動し、変速機６においてシフト対象となる図示しないシフトフォークを選択する。   As a result of the select operation, the inner lever (operating portion) 4 mounted on the shift and select shaft 1 is integrally slid in the axial direction together with the shift and select shaft 1, and a shift fork (not shown) to be shifted in the transmission 6 is moved. select.

シフト操作によって、シフトアンドセレクトシャフト１と共にインナーレバー４が一体で揺動され、シフト対象として選択したシフトフォークをスライド移動し、変速機６の変速させる。   As a result of the shift operation, the inner lever 4 is pivoted together with the shift and select shaft 1, and the shift fork selected as the shift target is slid to shift the transmission 6.

セレクト用のアクチュエータ２はモータによって構成される。このモータ２の出力軸２ａに設けられたギヤ７と、該ギヤ７と常時噛合うギヤ８と、該ギヤ８と一体回転する伝動軸９に設けられたピニオン１１と、該ピニオン１１と噛合うようにシフトアンドセレクトシャフト１に形成されたラック１ａとによって、前記モータ２の回転動力がセレクト操作力に変換される。   The selection actuator 2 is constituted by a motor. The gear 7 provided on the output shaft 2 a of the motor 2, the gear 8 that always meshes with the gear 7, the pinion 11 provided on the transmission shaft 9 that rotates integrally with the gear 8, and the pinion 11 mesh Thus, the rotational power of the motor 2 is converted into the select operation force by the rack 1a formed on the shift and select shaft 1 as described above.

シフト用のアクチュエータ３もモータによって構成される。このモータ３の出力軸３ａに設けられたギヤ１２と、該ギヤ１２と常時噛合うギヤ１３と、該ギヤ１３と共に一体的に回転する伝動軸１４に設けられたギヤ１６と、ギヤ１６と常時噛合うとともにシフトアンドセレクトシャフト１に一体回転可能且つ軸方向にスライド可能にスプライン結合されて支持されたギヤ１７とによって、前記モータ３の回転動力がシフト操作力に変換される。ギヤ１７に対してシフトアンドセレクトシャフト１が軸方向にスライドすることにより、前記セレクト操作が許容される。   The shift actuator 3 is also constituted by a motor. The gear 12 provided on the output shaft 3 a of the motor 3, the gear 13 that is always meshed with the gear 12, the gear 16 that is provided on the transmission shaft 14 that rotates integrally with the gear 13, The rotational power of the motor 3 is converted into a shift operation force by the gear 17 that is engaged with and supported by the spline coupling so as to be able to rotate integrally with the shift and select shaft 1 and slide in the axial direction. When the shift and select shaft 1 slides in the axial direction with respect to the gear 17, the select operation is allowed.

シフト用のアクチュエータ３とシフトアンドセレクトシャフト１との間にはダンパー装置１８が設けられている。このダンパー装置１８によって、変速機６からの衝撃が吸収され、その衝撃力がモータ３に伝わることが抑制される。   A damper device 18 is provided between the shift actuator 3 and the shift and select shaft 1. By this damper device 18, the impact from the transmission 6 is absorbed and the impact force is prevented from being transmitted to the motor 3.

次に、図１乃至図４に基づいて、ダンパー装置１８の構成を詳述する。   Next, the configuration of the damper device 18 will be described in detail with reference to FIGS.

図２は、ダンパー装置の構成を示す平面図であり、図３は、図２のＡ−Ａ断面図であり、図４は、図２のＢ−Ｂ断面図である。ダンパー装置１８は、図示する例では、伝動軸１４に設けられている。この伝動軸１４は、同一軸心をなし且つ別体形成された第１回転軸１４ａ及び第２回転軸１４ｂによって構成されている。   2 is a plan view showing the configuration of the damper device, FIG. 3 is a cross-sectional view taken along the line AA in FIG. 2, and FIG. 4 is a cross-sectional view taken along the line BB in FIG. The damper device 18 is provided on the transmission shaft 14 in the illustrated example. The transmission shaft 14 is composed of a first rotating shaft 14a and a second rotating shaft 14b that have the same axis and are formed separately.

変速機用シフトダンパ構造としてのダンパー装置１８は円盤状に成形され、厚み方向が上下方向に向けられた状態で支持されている。このダンパー装置１８は、第１回転軸１４ａと一体で回転作動する第１伝動部材１９と、第２回転軸１４ｂと一体で回転し且つ前記第１伝動部材１９と相対回転可能なように該第１伝動部材１９が上側から重ねられる第２伝動部材２１と、互いに異なる位置に配置された第１伝動部材１９と第２伝動部材２１との間に形成された複数の収容室２２にそれぞれ収容された圧縮スプリング２３とを備えている。   A damper device 18 as a shift damper structure for a transmission is formed in a disk shape and is supported in a state where the thickness direction is directed in the vertical direction. The damper device 18 includes a first transmission member 19 that rotates integrally with the first rotation shaft 14a, and a first transmission member 19 that rotates integrally with the second rotation shaft 14b and can rotate relative to the first transmission member 19. The first transmission member 19 is accommodated in each of a plurality of accommodation chambers 22 formed between the second transmission member 21 stacked from above and the first transmission member 19 and the second transmission member 21 arranged at different positions. And a compression spring 23.

各収容室２２は、第１伝動部材１９の下面に形成され且つ上方に窪んだ凹部２４と、該凹部２４の下方側に開口した部分を塞ぐ第２伝動部材２１とによって全体が形成されている。この収容室２２は、平面視で、第１伝動部材１９及び第２伝動部材２１の回転方向に沿う円弧状に成形されている。収容室２２内にオイル（流体）を注入させることにより、圧縮スプリング２３の伸縮作動を規制させることが可能である。   Each storage chamber 22 is formed entirely by a concave portion 24 formed on the lower surface of the first transmission member 19 and recessed upward, and a second transmission member 21 that closes a portion opened to the lower side of the concave portion 24. . The storage chamber 22 is formed in an arc shape along the rotation direction of the first transmission member 19 and the second transmission member 21 in plan view. By injecting oil (fluid) into the storage chamber 22, the expansion / contraction operation of the compression spring 23 can be restricted.

複数の収容室２２は、第１伝動部材１９及び第２伝動部材２１の回転方向に所定間隔毎に配置されている。第２伝動部材２１は、自身の回転中心部側から放射状に形成され且つ前記収容室２２を回転方向に仕切る作動部２６を有している。   The plurality of storage chambers 22 are arranged at predetermined intervals in the rotation direction of the first transmission member 19 and the second transmission member 21. The second transmission member 21 has an operation portion 26 that is formed radially from the rotation center side of the second transmission member 21 and partitions the storage chamber 22 in the rotation direction.

圧縮スプリング２３は、収容室２２の円弧形状に対して接線方向を向いた姿勢で、該収容室２２の内壁面と、前記作動部２６との間に圧縮状態で収容されている。圧縮スプリング２３，２３は、作動部２６の回転方向の両側に配置され、該作動部２６を両方向から弾性的に付勢するため、この作動部２６は収容室２２内の中立位置で弾力的に保持される。該構造によれば、第１伝動部材１９及び第２伝動部材２１は、圧縮スプリング２３によって、弾力的に接続され、一方から他方に動力を伝動させることが可能になる。   The compression spring 23 is accommodated in a compressed state between the inner wall surface of the accommodation chamber 22 and the operating portion 26 in a posture oriented in a tangential direction with respect to the arc shape of the accommodation chamber 22. The compression springs 23, 23 are arranged on both sides in the rotational direction of the operating portion 26, and elastically bias the operating portion 26 from both directions, so that the operating portion 26 is elastic at a neutral position in the storage chamber 22. Retained. According to this structure, the first transmission member 19 and the second transmission member 21 are elastically connected by the compression spring 23 and can transmit power from one to the other.

ちなみに、第２伝動部材２１に大きな衝撃力が作用した場合、該圧縮スプリング２３の弾性力に抗して、第２伝動部材２１が第１伝動部材１９に対して相対回転し（第１伝動部材１９及び第２伝動部材２１の回転差が生じ）、作動部２６が収容室２２の回転方向の一方寄りに変位する。   Incidentally, when a large impact force acts on the second transmission member 21, the second transmission member 21 rotates relative to the first transmission member 19 against the elastic force of the compression spring 23 (the first transmission member). 19 and the second transmission member 21 cause a rotation difference), and the operating portion 26 is displaced toward one side in the rotation direction of the storage chamber 22.

第１伝動部材１９の上面における平面視で収容室２２と重複する位置には、下方に窪んだオイル溜り部（流体溜り部）２７が凹設されている。言換えると、収容室２２毎にオイル溜り部２７が設けられている。このオイル溜り部２７と前記収容室２２とは、上下方向に延びる流動孔２８によって連通している。   An oil reservoir (fluid reservoir) 27 that is recessed downward is provided at a position overlapping the storage chamber 22 in plan view on the upper surface of the first transmission member 19. In other words, an oil reservoir 27 is provided for each storage chamber 22. The oil reservoir 27 and the storage chamber 22 communicate with each other through a flow hole 28 extending in the vertical direction.

オイル溜り部２７には、変速機を収容したミッションケース内のオイルが供給される。この供給の手段は、ギヤ等で、液面から飛散したオイルを直接的に受止めるようにしてもよいし、或いは、ポンプ等でオイル溜り部２７に強制的にオイルを供給してもよい。   Oil in the transmission case housing the transmission is supplied to the oil reservoir 27. The supply means may be a gear or the like that directly receives the oil scattered from the liquid surface, or the oil may be forcibly supplied to the oil reservoir 27 by a pump or the like.

このようにしてオイル溜り部２７に溜ったオイルは、流動孔２８を介して収容室２２内に流入する一方で、圧縮スプリング２３の伸縮作動等に起因してオイルが注入された収容室２２内の圧力が高まると、流動孔２８からオイルが流出する。   The oil accumulated in the oil reservoir 27 in this way flows into the accommodation chamber 22 through the flow hole 28, while the oil is injected into the accommodation chamber 22 due to the expansion and contraction operation of the compression spring 23. When the pressure increases, the oil flows out from the flow hole 28.

この流動孔２８はオイル溜り部２７毎に２つづつ設けられる。平面視で、この２つの流動孔２８，２８の間に、収容室２２内で中立な状態の作動部２６が位置している。第１伝動部材１９と第２伝動部材２１との間に回転差が生じた場合、作動部２６が収容室２２の中立位置から相対的に回転し、２つの流動孔２８，２８の何れかが作動部２６によって閉じられ、オイル溜り部２７から収容室２２内へのオイルの流入が規制される。一方、第１伝動部材１９と第２伝動部材２１との間に回転差が生じていない場合、作動部２６が収容室２２の中立位置で保持され、２つの流動孔２８，２８は両方とも開かれた状態になる。   Two flow holes 28 are provided for each oil reservoir 27. The operation part 26 in a neutral state in the storage chamber 22 is located between the two flow holes 28 in a plan view. When a rotation difference is generated between the first transmission member 19 and the second transmission member 21, the operating portion 26 rotates relatively from the neutral position of the storage chamber 22, and one of the two flow holes 28, 28 is It is closed by the operating part 26, and the inflow of oil from the oil reservoir part 27 into the storage chamber 22 is restricted. On the other hand, when there is no rotational difference between the first transmission member 19 and the second transmission member 21, the operating portion 26 is held in the neutral position of the storage chamber 22, and the two flow holes 28, 28 are both opened. It will be in the state.

図２および図４に示すように、２つの流動孔２８，２８と、これを開閉する作動部２６とによって、流動孔２８を選択的に開閉する選択機構１００が備えられる。この流動孔２８の閉作動によって、収容室２２のオイルの流入・流出が規制される一方で、開作動によって、このような規制が解除される。   As shown in FIGS. 2 and 4, a selection mechanism 100 that selectively opens and closes the flow hole 28 is provided by the two flow holes 28, 28 and an operation unit 26 that opens and closes the flow hole 28. While the flow hole 28 is closed, the inflow / outflow of the oil in the storage chamber 22 is restricted, while such restriction is released by the opening operation.

この選択機構１００がダンパー装置１８によって衝撃力が吸収される際に閉作動するため、収容室２２内に充填されたオイルの圧力が上昇する。この圧力上昇に伴って、圧縮スプリング２３の伸縮作動が規制され、それに起因した振動が抑制される。ちなみに、収容室２２内の圧力が必要以上に高圧になることを防止するため、所定以上の圧力になると、収容室２２内のオイルが排出用の油路２９からミッションケースへ排出される。   Since the selection mechanism 100 is closed when the impact force is absorbed by the damper device 18, the pressure of the oil filled in the storage chamber 22 increases. As the pressure rises, the expansion / contraction operation of the compression spring 23 is restricted, and the vibration caused thereby is suppressed. Incidentally, in order to prevent the pressure in the storage chamber 22 from becoming higher than necessary, the oil in the storage chamber 22 is discharged from the discharge oil passage 29 to the transmission case when the pressure exceeds a predetermined level.

以上のように構成される変速機用シフトダンパ構造によれば、ダンパー装置１８の弾力によって衝撃力が効率的に吸収されるとともに、衝撃力を弾力的に吸収させたことに起因して生じる振動を、収容室２２内のオイルによって抑制できる。   According to the shift damper structure for a transmission configured as described above, the impact force is efficiently absorbed by the elastic force of the damper device 18, and the vibration caused by the elastic absorption of the impact force. Can be suppressed by the oil in the storage chamber 22.

なお、本発明は、シフトアンドセレクトシャフト１を手動によってセレクト操作及びシフト操作されるものにも適用可能である。この場合は、２つのアクチュエータ２，３が省略され、シフトアンドセレクトシャフト１が手動操作用の図示しない変速レバーに機械的に連結される。   Note that the present invention can also be applied to those in which the shift and select shaft 1 is manually selected and shifted. In this case, the two actuators 2 and 3 are omitted, and the shift and select shaft 1 is mechanically connected to a shift lever (not shown) for manual operation.

また、流体はオイルに限定されるものではなく、圧縮スプリング２３の振動を規制可能な粘性を有するものであればよい。   Further, the fluid is not limited to oil, and any fluid may be used as long as it has a viscosity capable of regulating the vibration of the compression spring 23.

また、セレクト用のアクチュエータ２とシフトアンドセレクトシャフト１との間に配置された伝動軸９等にダンパー装置１８が設けられてもよい。或いはシフトアンドセレクトシャフト１自体にダンパー装置１８が設けられてもよい。   In addition, a damper device 18 may be provided on the transmission shaft 9 or the like disposed between the select actuator 2 and the shift and select shaft 1. Alternatively, the damper device 18 may be provided on the shift and select shaft 1 itself.
