Patent DE-19742596-A1 (DE)
Title: Damper for friction disc of friction clutch
Inventor: NAGANO TAMIO
IPC: F16F15/129
Filed: 1997-09-26
Abstract: The damper is made up of a hub (2), a separate flange (5) with limited rotational displacement between the two and connected via a spring (6). This flange (5) is held between a retaining plate (3) and a clutch plate (4) to which is fixed the clutch disc (12). Torque is transmitted between the flange (5) and the clutch plate (4) via springs (7). Three friction thrust bushes are provided (16,18,20). The first is placed between the retaining plate (3) and the hub (2). The second (18) is placed between the retaining plate (3) and the flange (5), both being connected to the retaining plate (4). The third is placed on the other side of the flange (5) between it and the clutch plate (4) to which it is connected. This thrust bush (20) acts on both the flange (5) and the hub (2). The coefficients of friction the between the bushes (16,18) are different while the part (22) of the bush (20) acting on the flange (5) has the same coefficient of friction at the second friction thrust bush (18) while that of the first bush (16) is the same as that of the third bush acting on the hub (2).
