Limited slip differential mechanism for an automotive vehicle and method for making the same

摘要

A limited slip differential assembly 100. The differential assembly 100 includes first and second housing portions 104, 106 which are formed by use of a flow-forming or spin-forming process and which respectively include an integrally formed splined inner surface 154, 156. The integrally formed splined inner surfaces 154, 156 are used to mate with clutch plates 146 which cooperate with clutch plates 144 to form clutch packs 150, 152. The novel splined engagement of clutch plates 146 and surfaces 154 and 156 provide improved durability, stiffness and torque capacity relative to prior designs.
