Patent attributes
A clutch for a belted transmission comprises a sheave, a first torque ramp member, a second torque ramp member, a drive ring and an electromagnet. The first torque ramp member is attached to the sheave and has a ramp face. The second torque ramp member is spaced apart from the first torque ramp member and has a ramp face opposing the ramp face of the first torque ramp. A drive ring is disposed between the first and second torque ramp members and has a button slider engaged between the ramp face of the first torque ramp member and the ramp face of the second torque ramp member. The electromagnet is configured for one of repelling the first torque ramp member from the second torque ramp member along a reference axis and attracting the first torque ramp member toward the second torque ramp member along the reference axis.
