Friction coupler for coupling drive shaft of engine of motor car with transmission input shaft, has return spring provided with certain angles formed between attachment points transverse to bending direction

摘要

The coupler (10) has a centrifugal force pendulum (36) comprising a pendulum mass (46), and a plate spring-like return spring (54) comprising two attachment points (58). One of the attachment points is connected with a counter plate (12) and/or a gear box-side coupler cover (18) on a radial height similar to the centrifugal force pendulum. The other attachment point is connected with a pressing plate (14) on a radial height smaller to the centrifugal force pendulum. The return spring is provided with certain angles formed between the attachment points transverse to a bending direction. The attachment points are designed as distant bolts i.e. rivets.
