Support spring i.e. plate spring, for starting clutch for coupling engine drive shaft with transmission input shaft of motor car, has inner sections extending in radial direction to midpoint of spring, and cup provided in axial direction

摘要

The spring (1) has a wire including ends connected with each other by material engagement. The spring is annularly formed. Inner sections (3) extend in a radial direction to a midpoint (M) of the annular support spring, and deviate from an annular circumferential contour (2). A cup is provided in an axial direction. The spring includes an inner radius (Ri) and an outer radius (Ra) along the annular circumferential contour, where a ratio of the outer radius to the inner radius lies in an interval of greater than 1.01 and lesser than 1.50, preferably greater than 1.02 and lesser than 1.35. An independent claim is also included for an actuating device.
