Abstract
A torsion damping device (10) of an automotive temporary coupling system, comprising: a torque input element (12A, 12B) and a torque output element (18); an upstream circumferentially acting elastic member (36A) capable of being loaded by or of loading the input element (12A, 12B); a downstream circumferentially acting elastic member (36B) capable of loading or of being loaded by the output element (18); a radial phase washer (40A, 40B) arranged so that the two elastic members (36A, 36B) are mounted in series; each elastic member (36A, 36B) is received circumferentially between a phasing face (50A, 50B) and an oppositely located radial retention face (52B, 52A) of the phase washer (40A, 40B), the circumferential distance (D) between said faces (50A, 50B, 52B, 52A) being equal at most to the circumferential length of the elastic member at rest.
