摘要： A retainer retaining a plurality of rollers therein so as to permit their slight movement in a radial direction is disposed between cam grooves provided on the outer periphery of an inner cam secured to a rotary shaft and a roller abutment surface formed on the inner periphery of a gear relatively rotatably carried on the rotary shaft, and a dowel-admission groove is defined in a side of the retainer. A dowel provided in a sleeve can enter the dowel-admission groove. The groove is defined between the adjacent rollers retained in the retainer, or at least part of the inner cam, the rollers and the retainer are disposed in a recess made in the gear, thereby achieving a reduction in axial dimension of a roller synchro mechanism. In addition, the retainer is comprised of two components: a body portion and a cover plate, thereby facilitating their machining, and a slide contact portion is formed on the outer periphery of the body portion and is tightly fitted to the roller abutment surface of the gear, so that the retainer may be dragged by the gear, thereby providing a prompt engagement of the rotary shaft with the gear.

摘要： A vehicle transmission of the type having a main shaft and a parallel counter shaft with a plurality of selectable gear trains therebetween. The axis of the engine crankshaft is disposed perpendicular to intermediate portions of the main shaft and the counter shaft, with the low speed gear trains and high speed gear trains positioned on opposite lateral sides of the crankshaft. This results not only in a reduced size of the transmission in the axial direction of the crankshaft but also in a reduced lateral size of the transmission, as compared with a transmission in which the crankshaft is connected in series to the transmission main shaft. A synchro mechanism is mounted on the counter shaft and a shift drum for operating the synchro mechanism is positioned parallel to the counter shaft. This insures a space for disposition of the synchro mechanism between gears of the relatively large diameter gears on the counter shaft and ensures a smooth shifting operation, without an increase in the lateral size of the transmission due to the shift drum.

摘要： An electronically controlled transmission in which a shift actuator for driving a sleeve of a roller synchro mechanism and a throttle actuator for an engine are electronically controlled. The shift actuator is comprised of a drum type actuator of a simple structure comprising a shift drum and a shift fork. The use of the roller synchro mechanism ensures that only a small driving force for the shift drum is required, which makes it possible to provide a reduction in size of the shift actuator. In addition, a shift lever for operating a shift switch for producing the shifting instruction signal is mounted on either left or right side of the steering wheel. This ensures that the shifting-up and shifting-down signals can be produced by one of the driver's hands, leading to an improvement in operability of the shift lever.

摘要： A shift control system for a vehicle transmission with multiple gear trains and a main shaft connected to an engine crankshaft through a clutch. The shift control system allowing shifting without disengaging the clutch. In conducting a shifting operation through a roller synchro mechanism associated with a gear train, the number of revolutions per minute of the engine crankshaft is promptly decreased through at least one of an ignition control device and a fuel supply control means to synchronize the number of revolutions per minute of a main shaft and a counter shaft of the transmission when the number of revolutions per minute of the main shaft is larger than the number of revolutions per minute for synchronizing with the counter shaft and the number of revolutions per minute of the engine crankshaft is increased to synchronize the number of revolutions per minute of the main shaft and the counter shaft when the number of revolutions per minute of the main shaft is less than the number of revolutions per minute for synchronizing with the counter shaft. This enables a prompt shifting.

摘要： A multi-speed transmission having a plurality of forward speed gear trains and at least one reverse speed gear train wherein two parallel shafts, one fixed and the other movable along its axial direction, are mounted within the transmission casing. Shifting forks are mounted on said shafts to selectively engage the forward and reverse speed gear trains. For example, for a multi-speed transmission having five forward speeds and one reverse speed, a first shift fork is slidably mounted on a stationary shaft to selectively engage the first and second gear trains, a second shift fork is slidably mounted on the slidable shaft to selectively engage the third and fourth gear trains and a third shift fork is mounted on the slidable shaft so as to be slidable in only one direction to engage the fifth speed gear train. Movement of the slidable shaft in the direction opposite that which engages the fifth speed gear train acts to engage the reverse speed gear train. The shift forks are retained in their selective position by retaining mechanisms which have retractable protrusions engageable with notches in the shafts.

摘要： A motor vehicle such as a four-wheel drive vehicle having a first axle shaft which is driven by a drive source and a second axle shaft which is driven by the same drive source, each of a pair of wheels associated with the second axle shaft being powered by way of individual variable torque transmitting devices, further comprising: a steering condition sensor; and a control unit which reduces a torque transmission ratio of one of the variable torque transmitting devices corresponding to the inner one of the wheels of the second axle shaft when the steering condition sensor has detected a steering angle greater than a prescribed value. Thereby, the problem of the tight turn braking can be avoided without losing the advantages of four-wheel drive. Other driving conditions such as braking and acceleration as well as an excessive temperature increase in each of the variable torque transmitting devices may be taken into consideration in carrying out the control of the variable torque transmitting devices which preferably consist of viscous couplings. Each of the viscous couplings is provided with means for externally varying the torque transmission ratio thereof and transmits torque between input and output thereof at a level which is substantially proportional to the speed difference between input and output thereof.
