Suspension stop device for MacPherson strut in motor vehicle, has self-lubricating element in contact over its entire surface with complementary surfaces of upper and lower caps, and absorbing axial and radial forces of suspension spring

摘要

The device (30) has an upper cap (32) mounted on a chassis of a motor vehicle, and a lower cap (33) having a lower surface (39c) forming a support surface for a suspension spring (31) intended to exert axial and radial forces on the device. A self-lubricating element (35) is arranged between the upper cap and the lower cap for forming a slider bearing. The self-lubricating element is in contact over its entire surface with complementary surfaces of the upper cap and the lower cap, and absorbs axial and radial forces of the suspension spring.
