    Abstract: A transmission includes a drive force transmission/interruption mechanism that restricts the rotation of a propeller shaft. By operating a shift lever, the shift operation of the transmission and the operation of the drive force transmission/interruption mechanism can be performed, and a lock operation and an unlock operation of a differential lock mechanism can be performed. When a driver wants to bring a vehicle into a parking state, by operating a shift lever, a state is provided where a drive force transmission/interruption mechanism is locked so that the rotation of a propeller shaft is restricted, and the vehicle can be held in a stopped state by bringing a differential lock mechanism into a locked state. Since the vehicle can be brought into a parking state using the shift lever, a so-called parking lever becomes unnecessary so that the number of operation elements can be reduced.

  • Patent number: 8821334
    Abstract: A multi-speed power transmission device includes an input shaft, first and second output shafts and a planetary gearset. An axially moveable sleeve fixes the first output shaft and the input shaft for rotation when in a first position and the sleeve fixes the sun gear and the input shaft for rotation when in a second position. A hub is axially moveable and free to rotate relative to the first output shaft when in the first position. The hub is fixed for rotation with the first output shaft when in the second position. A cam plate is continuously fixed for rotation with the carrier and urges the hub toward its second position when in a second axial position. The input shaft drives the first output shaft at a reduced speed via the planetary gearset when the sleeve, hub and cam plate are at their second positions.

  • Publication number: 20140179480
    Abstract: Construction of a continuously variable transmission device for a vehicle is achieved that, when a shift lever is shifted to a selection position for a direction opposite the traveling direction at that time, it is capable of preventing the vehicle from continuing to travel at high speed in a direction opposite the direction intended by the operator. When the shift lever is shifted to a selection position of a direction opposite the traveling direction at that time, and the vehicle speed is faster than a specified speed (V1), the connection of a clutch device that transmits power between a continuously variable transmission mechanism and a differential gear mechanism is disconnected, and the drive force from the drive source is prevented from being further transmitted to the wheels.
