Description

変速機用シフトダンパ構造Transmission shift damper structure
　この発明は、変速機用シフトダンパ構造に関する。 The present invention relates to a shift damper structure for a transmission.
　例えば、特許文献１は、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する第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、前記第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た変速機の操作装置を開示している。 For example, Patent Document 1 discloses a first transmission member that is rotated by transmission of an operation force of shift operation or selection operation by a manual operation or an actuator, and a position different from the first transmission member and relative to the first transmission member.

　上記文献の変速機の操作装置の場合、作動部からの衝撃は弾性部材によって吸収されるため、その衝撃が第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、衝撃を吸収した弾性部材がその後に振動する。この振動によって、手動でのシフト操作又はセレク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 case of the operating device for the transmission of the above document, the impact from the actuating portion is absorbed by the elastic member, so that the transmission of the impact from the second transmission member to the first transmission member is suppressed. On the other hand, the elastic member that has absorbed the impact vibrates thereafter. This vibration may cause a deterioration in the feeling at the time of a manual shift operation or a select operation, a deterioration in power control of the actuator, a deterioration in 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。 An object of the present invention is to provide a shift damper structure for a transmission that efficiently prevents the 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 subject, the 1st transmission member which powers and rotates the operation force of shift operation or selection operation by a manual operation or an actuator, it is arranged in a different position from the 1st transmission member, and is relative to the 1st transmission member. A second transmission member rotatably provided, and a storage chamber formed between the first transmission member and the second transmission member, the power of the first transmission member being transmitted to the second transmission member An elastic member for allowing the rotation of the second transmission member, and an actuating portion for performing a shift operation or a selection operation by the rotation of the second transmission member, wherein a fluid for restricting the operation of the elastic member is contained in the storage chamber It is characterized by comprising a selection mechanism which is filled and which allows the fluid to flow into and out of the storage chamber.
　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 restricts the outflow of fluid from the accommodation chamber and the inflow of fluid into the accommodation chamber when a rotation difference occurs between the first transmission member and the second transmission member. The restriction may be released when there is no rotational difference between the first transmission member and the second transmission member.
　前記流体が溜る流体溜り部が前記第１伝動部材に形成され、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。 The fluid storage portion in which the fluid is stored may be formed in the first transmission member, and the fluid stored in the fluid storage portion may be supplied to the storage chamber.
　収容室に充填された流体が、弾性部材の作動を規制することができる。このため、作動部からの衝撃を吸収した弾性部材の振動を効率的に抑制することが可能である。この振動の抑制によって、手動でのシフト操作又はセレク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。 The fluid filled in the storage chamber can regulate the operation of the elastic member. For this reason, it is possible to suppress efficiently the vibration of the elastic member which absorbed the impact from the operation part. By suppressing the vibration, it is possible to efficiently prevent the deterioration of the feeling at the time of the manual shift operation or the selection operation, the deterioration of the power control of the actuator, the deterioration of the controllability, and the like.

By injecting oil (fluid) into the storage chamber 22, it is possible to restrict the expansion and contraction operation of the compression spring 23.
　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 rotational direction of the first transmission member 19 and the second transmission member 21. The second transmission member 21 has an operating portion 26 which is radially formed from the side of the rotation center of the second transmission member 21 and which divides the storage chamber 22 in the rotational 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 operation portion 26 in a posture directed tangentially to the arc shape of the accommodation chamber 22. The compression springs 23, 23 are disposed on both sides in the rotational direction of the actuating portion 26, and resiliently bias the actuating portion 26 in both directions. It is held. According to this structure, the first transmission member 19 and the second transmission member 21 are elastically connected by the compression spring 23, and power can be transmitted 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 (a first transmission member 19 and the second transmission member 21 causes a rotation difference), and the actuating portion 26 is displaced to one side in the rotational 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 portion (fluid reservoir portion) 27 recessed downward is recessed 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 by 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。 The oil in the transmission case accommodating the transmission is supplied to the oil reservoir 27. The means for this supply may directly receive the oil scattered from the liquid surface by a gear or the like, 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 accumulation portion 27 in this manner flows into the accommodation chamber 22 through the flow hole 28, and the inside of the accommodation chamber 22 into which the oil is injected due to the expansion / contraction operation of the compression spring 23 or the like. When the pressure increases, oil flows out of the flow holes 28.
　この流動孔２８はオイル溜り部２７毎に２つずつ設けられる。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. In plan view, between the two flow holes 28, the working portion 26 in a neutral state is located in the storage chamber 22. When a difference in rotation occurs between the first transmission member 19 and the second transmission member 21, the actuating portion 26 relatively rotates from the neutral position of the storage chamber 22, and either of the two flow holes 28, 28 It is closed by the operating portion 26 and the inflow of oil from the oil reservoir 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 actuating portion 26 is held at the neutral position of the storage chamber 22, and the two flow holes 28, 28 are both open. It will be in a dry condition.
　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 for selectively opening and closing the flow holes 28 is provided by the two flow holes 28 and the operation unit 26 for opening and closing the flow holes 28. The closing operation of the flow holes 28 regulates the inflow and outflow of the oil in the storage chamber 22, while the opening operation cancels such regulation.
　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 is increased. Along with the pressure increase, the expansion and 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 excessively high pressure, the oil in the storage chamber 22 is discharged from the oil passage 29 for discharge 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 transmission shift damper structure configured as described above, the elastic force of the damper device 18 efficiently absorbs the impact force, 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。 The present invention is also applicable 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 coupled 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, 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 a transmission shaft 9 or the like disposed between the actuator 2 for selection and the shift and select shaft 1. Alternatively, the damper device 18 may be provided on the shift and select shaft 1 itself.
