Elastic torque transmission unit

摘要

An elastic damper of a clutch disc comprises a middle disc and two side discs. Helical compression springs are accommodated in overlapping windows of the middle disc and the side discs. The angular deflection of the side discs with respect to the middle disc is limited by a radially outer projection of the middle disc engaging recesses in axially approached lugs of the side discs projecting beyond the radially circumferential edges of the side discs.
