Abstract

PURPOSE:To improve a feeling of driving and reduce noise through reducing not only the quantity of lateral movement but also resisting force against a vertical movement by forming a trailing arm with a member which has sufficient elasticity in the left and right directions of a car body and high rigidity in the vertical direction. CONSTITUTION:The front edge of a trailing arm 1 is pivoted through a rubber bush 2 on a body frame so as to freely sway vertically, while a knuckle arm 3 is fitted on the rear end of said arm 1. A spindle 5 projected outward from the knuckle arm 3 rotatably supports a wheel 6. The arm 1 is formed by a member which has sufficient elasticity in the left and right directions of a car body and high rigidity in the vertical direction. Lateral movement is borne by lateral deflection of the arm 1 and deflection of the bush 2, thereby reducing the resisting force against vertical movement of the arm 1 generated in the bush 2. Deterioration of the feeling of driving and generation of a noise and the like due to said resisting force are prevented.

ができる。Therefore, the toe change caused by the vertical movement of the wheel 6 is corrected by the lateral movement of the trailing arm 1 due to the restraining action of the correction link 9, but the trailing arm 1 is deflected by the correction link 9 as shown in FIG. Therefore, the lateral movement is borne by the lateral deflection of the trailing arm 1 and the flexure of the bushing 2. As a result, the amount of lateral movement of the bushing 2 is reduced by the lateral deflection of the trailing arm 1 compared to the conventional one. Therefore, the resistance force generated in the bush 2 portion against the vertical movement of the trailing arm 1 is also reduced, and it is possible to effectively prevent a reduction in ride comfort, generation of noise, etc. due to this resistance force.
