摘要： A system for lubricating a transmission for a vehicle includes an auxiliary oil reservoir placed in the transmission case apart from transmission gears, an oil pump in the transmission case operated interlockingly with an output shaft of the transmission for pumping lubricating oil stored in the bottom of the case into the auxiliary oil reservoir, and a circulating means provided in the auxiliary oil reservoir for regulating the amount of oil circulated from the auxiliary oil reservoir into the transmission case, such that the amount of oil in the auxiliary oil reservoir is increased or decreased in accordance with a respective increase or decrease in the amount of oil discharged from the oil pump. This system allows the amount of lubricating oil stored in the transmission case to be reduced in accordance with an increase in vehicle speed, while ensuring the transmission is lubricated to a sufficient extent at all times by an oil splash scattered from the gears over the vehicle's full operating range, while avoiding attendant power loss and excessive rise in oil temperature which may otherwise result during high speed operation.

摘要： A multiple-disk clutch apparatus including an input-side rotatable member having a clutch disk pressing surface, a pressure plate attached to the input-side rotatable member and disposed on an axially rear side opposing the pressing surface, a plurality of clutch disks disposed between the pressing surface and the pressure plate with an intermediate plate being interposed between the clutch disks, and a stopper member for restricting an axially rearward return position of the intermediate plate at the time of clutch disengagement. The stopper member is mounted on the input side rotatable member via a one-way mechanism which allows an axially forward movement of the stopper member but which restricts an axially rearward movement thereof. A holder for holding the one-way mechanism can be mounted on the input side rotatable member so as to be movable axially rearward against a spring. A restriction portion for restricting an axially forward movement of the holder can be formed in the input side rotatable member. A shock absorbing member can be interposed between the restriction portion and the holder.

摘要： A changing system in a manual transmission is provided. An interlock plate is mounted on a shift-selecting shaft capable of being moved axially in response to a selecting operation and turned about an axis in response to a shifting operation, so that the interlock plate cannot be turned about an axis of the shift-selecting shaft. The interlock plate has a pair of side plate portions which are provided at locations spaced apart from each other in an axial direction of the shift-selecting shaft and through which the shift-selecting shaft extends. A shifting arm disposed between the side plate portions is fixed to the shift-selecting shaft. In such changing system, the shifting arm and an interlock member operatively connected to the shifting arm are interposed between the side plate portions of the interlock plate. Thus, the shifting arm can be used commonly in manual transmissions, in despite of a difference in number of forward speed stages between the manual transmissions, thereby providing a reduction in cost and avoiding an increase in weight due to a variation in number of forward speed stages.

摘要： A gear shift apparatus for a manual transmission utilizes an actuator to prevent a miss shift manipulation from a forward gear stage to a reverse gear stage. The gear shift apparatus permits the driver to forcedly release a mis-shift preventing state with a smaller force. In the gear shift apparatus for a manual transmission, a select cam is responsive to a selecting manipulation to pivotally move to forward positions corresponding to forward select positions and a reverse position corresponding to a reverse select position. A restraint cam is driven to a prohibiting position by a plunger when a solenoid is energized to prohibit the select cam from pivotally moving to the reverse position. In this prohibiting state, as the select cam is pivotally moved toward a forward position in response to a manipulation for selecting a forward select position, a release protrusion of the select cam presses the restraint cam to pivotally move the same from the prohibiting state to a permitting position.

摘要： A vehicular transmission having multiple gear trains including an ultra-low speed for all-wheel operation. A gear train selecting and shifting mechanism includes a select shaft and a shift shaft rotatably mounted perpendicular to each other. A shift piece slidably mounted on another shaft for engaging the shift forks for establishing the selected gear train. An arm is mounted on the select shaft for pivoting thereby and engages the shift piece for selecting the desired shift fork. Another arm is mounted on the shift shaft for pivoting thereby and engages the shift piece for causing shifting of the gear trains. Push-pull wires are provided from the driver's position for causing rotation of the select and shift shafts through external levers. An interlock plate prevents selection of the shift fork for the ultra-low speed unless a transfer gear clutch is engaged for all-wheel vehicle operation.

摘要： A multi-stage gear shift transmission comprising a plurality of forward stage gear trains capable of being alternatively established, and a reverse stage gear train having an idle gear portion meshed with a reverse input gear and a reverse output gear. The forward stage and reverse stage gear trains are provided between an input shaft and an output shaft parallel to the inut shaft. A reverse stage establishing clutch mechanism is interposed in the middle of the reverse stage gear train. The idle gear portion is divided into a first idle gear meshed with the reverse input gear, and a second idle gear meshed with the reverse output gear and capable of being connected to the first idle gear through the reverse stage establishing clutch mechanism. The reverse stage establishing clutch mechanism comprises a sleeve which is engaged with the first idle gear for relative non-rotation and for axial relative movement and which is capable of being meshed with the second idle gear, a braking member which is disposed between the first and second idle gears for axial movement so that it may be urged toward the second idle gear in response to the movement of the sleeve toward the second idle gear and which is capable of being rotated in unison with the first idle gear, and a stationary part fixedly disposed to temporarily frictionally engage with the braking member when the braking member is moved toward the second idle gear.

摘要： A shifting apparatus for a transmission of a vehicle comprising a shift lever operable left and right for travel to selection positions and front and rear for shifting gears, the shift lever being shiftable in one of the selection positions between a forward gear position and a reverse gear position. A projection is movable with the shift lever vertically in the selection operation and horizontally in the shift operation. A pivotable lock member is positioned in the vertical path of travel of the projection and the lock member and projection are provided with cam surfaces such that the lock member is pivoted, when the projection is moved, from a neutral position to an inoperative position. The lock member is held in its neutral position by a spring and in the inoperative position the shift lever is movable to the forward gear position and to the reverse gear position. When the projection is moved to the selection position, the cam surfaces are cooperatively engaged to pivotably move the lock member to its inoperative position and if the shift lever should then be moved to the forward gear position, the lock member is then pivotably moved by the spring to its neutral position at which any movement of the shift lever to the reverse gear position will cause the projection to engage a claw on the lock member. A stop member is fixed in the path of travel of the lock member to prevent pivotal movement of the lock member in this position and thereby prevent travel of the shift lever to the reverse gear position.
