The shock absorber (50), designed to act as a stop (42) in a double damping flwheel of a motor vehicle transmission system is made at least partly from an elastomer material with a resistance to heat aging of between 125 and 175 degrees C and a swelling in oil of less than 60, and preferably less than 45 per cent. The elastomer material is selected from the group comprising fluoroelastomers, acrylic ethylene rubbers, perfluoridated elastomers, acrylic rubbers, hydrogenated nitrile rubbers and mixtures of these, including Viton (RTM - fluoroelastomer)), Vamac (RTM - acrylic ethlene terpolymers and dipolymers) and Kalrez (RTM). |
