LOCK-UP CLUTCH FOR A HYDROKINETIC POWER TRANSMISSION APPARATUS FOR A MOTOR VEHICLE

摘要

A lock-up clutch for a hydrokinetic power transmission apparatus comprises firstly a coupling element, and secondly a torsion damping device comprising two coaxial parts which are mounted for relative rotation of one with respect to the other against the action of circumferentially acting resilient members, with one of the said coaxial parts comprising two retaining members so shaped as to retain the resilient members in position. The coupling element constitutes one of the retaining members, by virtue of an outer flange formed for this purpose on its outer periphery. This outer flange is so shaped as to receive within it part of the resilient members in such a way that the coupling member constitutes a guide ring.
