Abstract
A transmission clutch including: a carrier; a clutch pack; friction plates; a compression plate including a portion; and a first ramp ring including: a first portion in contact with the portion of the compression plate; and a second portion. The clutch includes a second ramp ring including a third portion axially aligned with the second portion; a lever spring; and a piston. The piston displaces the spring in an axial direction such that: the spring applies a force to the second portion; the first ramp ring rotates in a circumferential direction and axially displaces in the axial direction; and the first ramp ring urges the compression plate in the axial direction to contact the clutch pack. The piston displaces the lever spring further in the axial direction such that the compression plate clamps pressure plates and friction plates in the clutch pack to rotationally fix the carrier to the housing.
