Abstract
The driving member of this torsional impulse damper is a disc-like plate, coaxially securable at its peripheral portions to an engine flywheel. The driven member comprises two carrier elements, at opposite sides of the driving member, rigidly connected at bosses that are spaced from the rotational axis and extend through larger holes in the driving member. Friction surfaces on inner faces of the carrier elements engage the opposite flat faces of the driving member. Cooperating with the friction surfaces to maintain the driving and driven members coaxial is a coaxial trunnion on one carrier element projecting into a bearing fitted in a central hole in the driving member. The carrier elements cooperate to enclose springs that react between the driving and driven members. A universal joint at one end of a drive shaft is directly connected to one of the carrier elements.
