Abstract
An angular damping device (10) for a motor vehicle temporary wet coupling system comprises two radial guide washers (24) which are positioned axially one on each side of a web (12),at least two elastic members (38) with circumferential action which are circumferentially interposed in series between the web (12) and the guide washers (24), and a phase member (42) which comprises at least one radial phase lug (48). The phase member (42) further comprises two friction pads which can parted axially against each of the guide washers (24). Each of the friction pads comprises a retaining face (54) for retaining an elastic member (38) against the action of centrifugal force. The elastic member (38) is partially inserted between the two retaining faces (54)in the manner of a wedge.
