TRAILING ARM TYPE SUSPENSION WITH LATERAL LINK

PURPOSE:To improve the control stability of a car by reducing the backward angle of a line connecting the camber direction elastic center to a pivot point between a lateral link and a trailing arm against a vertical plane in the car body longitudinal direction in case of the suspension device for independently suspending rear wheels inscribed in the heading. CONSTITUTION:Non-padding parts on both ends of an outside elastic bushing 2 for supporting a trailing arm are made shallower in their depth than the non- padding parts of an inside elastic bushing 3, and the rigidity of the inside bushing 2 is made larger. Accordingly, a camber direction elastic center P shifts to the outside bushing 2 side due to the rigidity difference between both bushings 2, 3, allowing the backward angle alpha of a movement center axis 9 against the vertical plane 10 in the car body longitudinal direction to be reduced. Hereby, when turning force F is applied to rear wheels 5, the difference between the traveling radii of the points A, B is reduced, allowing the change of a toe angle of the car wheels 5 in toe-out direction to be reduced. Consequently, it is possible to improve the control stability of a car.
