High performance automotive clutch with modified pressure plate for sustained increased spring force

摘要

Belleville spring pressure plate of increased height for use in a high performance clutch assembly exerts a greater force than the original height plate, is usable without modification of the original clutch and is longer lasting in service after being thermally conditioned to a martensitic state to lose the memory of its original, lower height and stress tempered before being set in a new, increased height shape.
