Torsion damping device, especially clutch friction and torque transmission device incorporating such a damper

摘要

Improvement to a torsion damper, especially clutch friction for a motor vehicle. According to the invention, the torsion damper comprises elastic means with circumferential action constituted by a first disc made from elastomeric material 18 interposed between the hub 12 and the friction disc 11 and a viscous damping arrangement 16 confined inside a sealed chamber 17, the disc made from an elastomeric material 18 contributing to the sealing of the said chamber. Application to the motor industry. <IMAGE>
