Abstract
The present invention concerns a suspension thrust bearing device adapted to receive a shock absorber piston rod along a main axis (X1), the device including a single bearing forming an axial thrust bearing and including an inner race, an outer race and rolling members disposed between the inner race and the outer race, and at least one intermediate member adapted to transmit to the inner race essentially axial forces exerted on the device by a suspension spring. One of the inner race and the intermediate member extend(s) radially beyond the outer race in the direction of the main axis (X1), forming a bearing surface for fixing and centering the shock absorber piston rod relative to the device. The invention also concerns a motor vehicle McPherson strut including a shock absorber and a suspension thrust bearing device as referred to above.
