  • Publication number: 20200171905
    Abstract: The purpose of the present invention is to improve the driving stability of a vehicle in which a double wishbone type or multi-link type suspension is adopted. A double wishbone type suspension has a sliding bearing disposed between a coil spring provided coaxially with a shock absorber and an upper support for mounting the coil spring to the body of the vehicle along with the shock absorber, the sliding bearing permitting the coil spring and the upper support to rotate relative to each other. The sliding bearing permits the coil spring and the upper support to rotate relative to each other with torque lower than torque generated by the torsion of the coil spring caused by the load of the vehicle acting on a damper assembly.
