Abstract
A suspension stop device, for a motor vehicle driving wheels, including a filtering block, having an upper housing fixed relative to the vehicle body and co-operating with a lower housing mobile in rotation about a shock absorber rod and supporting a suspension spring, and a ball bearing. The upper and lower housings are made of thermoplastic material and have opposite surfaces hollowed out in a circle, about the rotation axis of the shock absorber rod, to receive a raceway for the ball bearing. The upper housing further incorporates an impact stop molded around the leading stop of the shock absorbing device, and the thermoplastic structure of the upper housing is reinforced by a ring made of overmolded elastomer.
