Abstract
A clutch assembly, a torque converter clutch assembly, and a brake assembly for a vehicle are disclosed. The clutch assembly and the brake assembly may have at least one reaction plate comprising an internal cavity containing a phase change material. The torque converter clutch assembly may have a front cover plate comprising an internal cavity containing a phase change material. The phase change material may be capable of absorbing at least some friction-induced heat generated at a friction interface of the reaction plate or front cover plate when the clutch assembly, the torque converter assembly, or the torque converter assembly is shifted to a closed position, such as when the clutch is activated or when the brakes are applied.
