摘要： A transmission system has a housing including a wall and a gear support extending from the wall. The gear support has an outer surface and an inner surface defining a passage. The outer surface includes a seal receiving portion and a seal support axially spaced from the seal receiving portion. A seal is positioned about the gear support at the seal receiving portion. A sleeve is arranged on the outer surface of the gear support between the wall and the seal and a pump drive gear is mounted on the gear support and is supported by the sleeve. The pump drive gear includes an outer toothed surface, an inner surface, and a bushing arranged on the inner surface, the bushing extending about the sleeve.

摘要： An automatically-shiftable transaxle includes an input member configured to receive an external power-source torque and rotate about a first axis. The transaxle also includes torque transmitting device(s) and a gear-train, each operatively connected to the input member for selecting transaxle speed ratios, and a first transfer gear operatively connected to the gear-train and rotatable about the first axis. The transaxle also includes an intermediate shaft rotatable about a second axis, and a second transfer gear rotatably fixed to the intermediate shaft and meshed with the first transfer gear. The transaxle additionally includes an electric motor arranged on a third axis for providing a torque input to the second transfer gear. Furthermore, the transaxle includes a differential assembly operatively connected to the intermediate shaft and rotatable about a fourth axis to thereby transmit a transaxle output torque to drive the load. All four transaxle rotational axes are arranged in parallel.

摘要： A final drive unit for a motor vehicle includes a sprocket driven by a transmission, a first planetary gear set where one of the rotational members is connected to the sprocket, a second planetary gear set where one of the rotational members is connected to the first planetary gear set, and an actuator moveable between a low range position and a high range position. The actuator is rotationally coupled to a differential. When the actuator is in the low range position, the actuator rotationally couples one of the rotational members of the second planetary gear set to the differential. When the actuator is in the high range position, the actuator rotationally couples another of the rotational members of the second planetary gear set to the differential.

摘要： A continuously variable transmission (CVT) for a motor vehicle includes a transmission input shaft rotatably connected to an engine by a torque converter, the transmission input shaft defining a first CVT axis. A continuously variable unit connected for rotation by the transmission input shaft includes a first pulley assembly, a second pulley assembly, and a flexible member wrapped around the first pulley assembly and the second pulley assembly. A two mode transfer gear assembly is connected to the second pulley assembly and is coaxially aligned for rotation on a second CVT axis. A clutch assembly having at least one clutch is connected to the transfer gear assembly. A final drive unit connected to the transfer gear assembly is co-axially aligned with respect to the second CVT axis.

摘要： A multi-mode continuously variable transmission in a powertrain of a motor vehicle includes a continuously variable unit connected to a planetary gear set arrangement. The planetary gear set arrangement generally includes two planetary gear sets, two brakes, and one clutch and provides multiple modes of ratio selection between the continuously variable unit and a transmission output member. The transmission output member is connected to a chain driven final having only three axes of rotation.

摘要： A transmission is provided having a housing, a plurality of planetary gear sets, a structural member, a sprocket member, an annular drum, a band, and an actuator. The sprocket member is rotationally supported by the structural member. The annular drum is adjacent the structural member and is continuously rotationally coupled with a member of the one of the plurality of planetary gear sets. The band circumscribes the annular drum and includes at least a first position and a second position. In the first position the band is substantially separated from the drum and in the second position the band contacts the drum. The actuator selectively positions the band between at least the first position and the second position to transfer torque between the structural member and the annular drum.
