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 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 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 continuously variable transmission that includes an input assembly, an output assembly, an input/output planetary ratio assembly and a torque feedback control is provided. The input assembly is coupled to receive input rotational motion. The output assembly is rotationally coupled to a load. The input/output planetary ratio assembly sets an input to output speed ratio. The input/output ratio assembly has a first portion that is in rotational communication with the input assembly and a second portion that is in rotational communication with the output assembly. The torque feedback control assembly provides an axial load force in response to a torque of a load coupled to the output assembly. A differential assembly sets the input to output speed ratio of the input/output planetary ratio assembly based at least in part on an axial load force of the torque feedback control assembly.
