摘要： An integrated launch clutch and drive sheave for a continuously variable transmission (CVT) is provided. The integrated launch clutch and drive sheave includes a drive sheave, a launch clutch and an integrated hydraulic system. The drive sheave includes a fixed sheave member that is statically mounted on and rotationally fixed to a drive sheave post and a movable sheave member that is slidably mounted on the drive sheave post. The launch clutch is in rotational communication with a motor. The launch clutch is configured to selectively couple engine torque from the motor to the drive sheave post of the drive sheave. The integrated hydraulic system is configured to both activate the launch clutch to selectively couple engine torque between the motor and the drive sheave and to axially move the movable sheave member on the drive sheave post of the drive sheave in relation to the fixed sheave member.

摘要： A locking angle gear box is provided. The locking angle gear box includes a torque transfer assembly, a ring gear, at least one connection drive assembly and an actuator. The torque transfer assembly is configured to communicate torque between the torque transfer assembly and a pair of outputs to halfshafts. The ring gear is rotationally supported on the torque transfer assembly. The ring gear is configured to transfer torque between at least a portion of a driveline and the torque transfer assembly. The at least one connection drive assembly is configured to selectively lock rotation of the torque transfer assembly with the rotation of the ring gear to selectively couple torque between the torque transfer assembly and the ring gear. The actuator is in communication with the at least one connection drive assembly to selectively manipulate the at least one connection drive assembly.

摘要： A clutch assembly for driveline components is provided. The ball ramp having first and second ball ramp members and at least one ball is provided. The first ball ramp member of the ball ramp is in operational communication with an input member to the clutch assembly. A first set of plates of a clutch pack are in operational communication with the input member and a second set of plates of the clutch pack are in operational communication with an output member. A sprag clutch assembly that is operationally coupled to the second ball ramp member of the ball ramp, only allows the second ball ramp member of the ball ramp to rotate in first direction. A thrust bearing that is in operational communication with the second ball ramp member of the ball ramp selectively disengages the clutch pack when the output member rotates in a second direction.

摘要： A dual clutch transaxle is provided that includes a dual clutch assembly, an input shaft assembly, a counter shaft assembly, a shift assembly and at least one output assembly. The dual clutch assembly has a dual clutch axis and includes a first clutch shaft and a second clutch shaft. The input shaft assembly includes a nested first inner input shaft and a second outer input shaft that are operationally coupled to the first clutch shaft and a second clutch shaft. An input shaft axis is offset from the dual clutch axis of the dual clutch assembly. A plurality of drive gears of the input shaft assembly are operationally coupled to a plurality of driven gears of the counter shaft assembly. The shift assembly is operationally coupled to select. The at least one output assembly is operationally coupled to the counter shaft assembly.

摘要： A primary clutch of a continuously variable transmission with a launch mechanism is provided. The primary clutch includes a central post, a fixed sheave assembly, a movable sheave assembly and a locking mechanism. The central post is configured to receive rotational torque from a motor. The fixed sheave assembly is statically mounted on the central post. The movable sheave assembly is mounted on the central post. The movable sheave assembly includes a movable sheave system that is configured to move axially on the central post towards the fixed sheave assembly as RPM of the primary clutch increase. The locking mechanism is configured and arranged to selectively prevent movement of the movable sheave system independent of the RPM of the primary clutch.

摘要： A drive clutch including a primary post, a fixed sheave, a movable sheave, an activation assembly is provided. The fixed sheave is statically coupled to the primary post. The movable sheave is slidably mounted on the primary post. The activation assembly is in operational communication with the movable sheave to move the movable sheave on the primary post away from and towards the fixed sheave based on a centrifugal force experienced by the drive clutch. The activation assembly includes a spider, at least one trunnion slidably mounted on a spider arm and a main activation biasing member. The at least one trunnion has opposable extending trunnion arms. A roller is rotationally mounted on each trunnion arm. Each roller is positioned to engage a ramp profile associated with a sheave post extending from the movable sheave. The main activation biasing member is positioned to assert a biasing force on the spider.
