Abstract
A suspension system is provided with a suspension cross member 12 for rear wheels, a suspension member supported on the suspension cross member 12, elastic mounts 19 to 21 for mounting the suspension cross member 12 on the vehicle body, the elastic mounting means 19 to 21 being provided at three positions along forward and backward directions in such a manner as to form a triangle when the vehicle body is viewed sideways. Thus, a change in wheel alignment can be effectively suppressed without reducing a vehicle's comfort to ride.
Claims8
A suspension system for a vehicle comprising:
- a suspension cross member;
- a suspension member for a rear wheel supported on the suspension cross member;
- first type elastic mounting means for mounting the suspension cross member on a vehicle body, the first type elastic mounting means being mounted at three positions along forward and backward directions of the vehicle body and forming a triangle when the vehicle body is viewed sideways;
- a rigid frame for coupling a power unit provided at a front part of the vehicle body to a differential provided at a rear part of the vehicle body;
- and
- second type elastic mounting means for mounting the differential on the suspension cross member, a spring constant of the second elastic mounting means being set smaller than that of the first type elastic mounting means.
