Abstract:
A suspension strut (1a) used in a wheel suspension of an automotive vehicle comprising a shock absorber (20) and a coil spring (21) arranged substantially coaxially around the shock absorber (20), said suspension strut (1a) being connected to a steering knuckle (5) and a vehicle body (4) at articulation points (2, 3), a bearing (6a) being mounted sealed between the suspension strut (1, 1a) and a vehicle body (4) while being surrounded by a first carrier element (10a) associated to the vehicle body (4) and a second carrier element (11a) oriented toward the shock absorber (20), one of which carrier elements cooperates with a damping element (24) for forming an elastic end stop, characterized in that the bearing (6a) is supported by one bearing ring (7, 8) directly on each carrier element (10a, 11a) and the first and second carrier elements are made of different materials, the first carrier element (11a) being made of plastic and the second carrier element (10a) being made of steel sheet, both carrier elements are rigid and comprise rims (12a, 13a, 14a) which point axially towards each other and on which at least one bearing ring (7, 8) is centered and each bearing ring (7, 8) is supported on the carrier elements (10a, 11a) by a flat annular surface extending at right angles to a longitudinal axis of the suspension strut (1a).
