A pack includes a set of first friction disks interleaved with a set of second friction disks to form a stack. An annular pressure plate has an engagement side disposed against the stack. The engagement side includes an outer circumferential edge, an inner circumferential edge, a flat face extending radially inward from the outer edge, a step axially recessed into the engagement side relative to the face, and a tapered face extending from the step to the inner circumferential edge. The tapered face is disposed against an end one of the first friction disks, and the flat face is radially outboard of the first friction disks.

Clutch assembly pressure plate with tapered face

A vehicle transmission includes a transmission shaft, a friction element assembly mounted on the transmission shaft, a piston assembly for actuating the friction element assembly, a snap ring for retaining the friction element assembly and a mounting groove formed in the transmission shaft. The snap ring is installed into the mounting groove by expanding the snap ring and then allowing the snap to contract and enter the mounting groove. The mounting groove is located such that the snap ring could exit the mounting groove upon expansion of the snap ring due to a centrifugal force. Accordingly, various arrangements are provided to prevent the snap ring from leaving the mounting groove after installation.

Vehicle transmission and method of assembling vehicle transmission

A vehicle transmission includes a first rotating element, second rotating element, first retainer ring, and second retainer ring. The first rotating element has an exterior surface that defines a first ring groove. The second rotating element is configured to limit movement of friction plates during clutch engagement. The second rotating element is disposed about the exterior surface and has an interior surface that defines a second ring groove. The first retainer ring is disposed in the first ring groove. The second retainer ring is disposed in the second ring groove and thereby restricts movement of the first retainer ring in a radially outward direction.

Transmission and transmission clutch system

The present disclosure relates to a vehicle transmission clutch assembly with squawk reduction techniques, having: a clutch component configured to rotate with respect to a transmission shaft; and a plurality of multi-directional mass dampers coupled to the clutch component, configured to alter a mode of vibration for the clutch component during clutch engagement.

Transmission clutch assemblies with squawk reduction techniques

A clutch assembly includes a hub rotatable about an axis and at least partially surrounding a cavity, a damper ring within the cavity, able to revolve about the axis, rotatable relative to the hub, a spring, a friction disc, forced elastically by the spring into contact with the damper ring, and a second friction disc contacting the damper ring and providing a reaction to the force of the spring.
