An infinitely variable belt-drive transmission for a vehicle, having a clutch for transmitting engine power to wheels of the vehicle, a drive pulley having a hydraulically shiftable disc and a hydraulic cylinder for shifting the disc, a driven pulley having a hydraulically shiftable disc and a hydraulic cylinder for shifting the disc, and a belt engaged with said both pulleys. The transmission comprises an input shaft connected to a driven member of the clutch, a main shaft connected to the drive pulley and a drive gear secured to the input shaft. A synchronizer is securely provided on the main shaft to be engaged with the drive gear, and a counter gear engage with the drive gear. An idler gear is provided to be engaged with a gear on the synchronizer and with a gear of the counter gear so as to provide a reverse drive transmission.

Infinitely variable belt-drive transmission

A parking system for a vehicle having a fluid operated clutch or electromagnetic clutch. A shifter arm is rotatably and axially slidably mounted on a shaft and a link mechanism is provided for transmitting the operation of the gear shaft lever to the shifter arm for rotating and sliding it. In a transmission of the vehicle, a parking shifter rail provided for parking operation is connected to the shifter arm by a fork. A parking pawl operatively engages the parking shifter rail, and a parking gear in the transmission engages the parking pawl. When the gear shift lever is shifted to the parking position, the parking pawl is rotated by the movement of the parking shifter rail and engaged with the parking gear. Thus, the transmission system of the vehicle is locked by the parking pawl.

Parking system for a vehicle

A transmission apparatus for a motor vehicle having an internal combustion engine transversely disposed in the vehicle at an end portion thereof, a transmission transversely disposed and connected to the crankshaft of the engine at one end portion of the transmission, a final reduction gear engaged with an output gear of the transmission, the output gear being mounted on an output shaft of the transmission adjacent an end of the engine, a differential secured to a side of the final reduction gear, and an axle connected to the differential for one pair of the vehicle wheels. A transfer device is connected to another portion of the output shaft of the transmission. The transfer device comprises a transfer shaft, a gear train provided at the other end portion of the transmission, and a clutch device for engaging the gear train with the output shaft of the transmission. A propeller shaft is connected to the transfer device for driving other axles of the vehicle for the other pair of vehicle wheels for four-wheel drive.

Transmission apparatus for a four-wheel drive motor vehicle

A transmission apparatus for a motor vehicle having an internal combustion engine transversely disposed in the vehicle, a transmission transversely disposed and connected to the crankshaft of the engine through a clutch, a final reduction gear engaged with an output gear of the transmission, a differential secured to a side of the final reduction gear and disposed at a substantially central position of the vehicle, and an axle connected to the differential. A transfer device is connected to the final reduction gear and disposed adjacent the differential. The transfer device comprises a supporting shaft, a gear engaged with the final reduction gear, a clutch, and a first bevel gear. A second bevel gear is engaged with the first bevel gear, and a centrally located propeller shaft is operatively connected to the second bevel gear for driving another axle for the four-wheel drive.

Transmission apparatus for four-wheel drive motor vehicle

A control mechanism for a transmission apparatus for a four-wheel drive motor vehicle comprising an auxiliary change-speed transmission adapted to transmit power from the engine to a main transmission, a final reduction device for transmitting the output of the main transmission to the front axle and to the rear axle, a clutch connected to the final reduction device for transmitting the output of the main transmission for selectively connecting or disconnecting transmission of the output to one of the axles. An operation rod is longitudinally and slidably provided for swinging first and second guide plates. Each guide plate has a guide groove with which a part of a fork engages. By operating the operation rod, first and second guide plates are swung to cause the forks to shift with engagement with the guide grooves. The guide grooves are so arranged as to establish two-wheel high speed range driving, four-wheel high speed range driving and four-wheel low speed range driving.

Control mechanism for a transmission of a four-wheel drive vehicle

A transmission apparatus for four-wheel drive motor vehicle comprising a sub-transmission adapted to transmit power of the engine to a main transmission, means for transmitting the output of the main transmission to the front axle and to the rear axle, clutch device provided in the means for transmitting the output of the main transmission for selectively connecting or disconnecting the transmission of the output to either of the front or rear axle, a shift rod shifting the clutch mechanism in the sub-transmission, an actuating rod slidably provided in parallel with the shift rod, a shift lever connected to the actuating rod, and a shift fork slidably mounted on the actuating rod and engaged with the clutch device. There is provided with first engaging mechanism for causing the actuating rod and shift fork to come into fixed engagement relation to each other within a first moving range of the shift lever, and second engaging mechanism provided for causing the actuating rod and shift rod to come into fixed engagement relation to each other within a second moving range of the shift lever adjacent the first moving range, whereby the motor vehicle may be driven at an economical higher speed range and at a powerful lower speed range.
