PURPOSE:To attempt improvement of running stability particularily at high speed where a front link is adapted to secure a rear wheel to a car body side via elastic members in such a way as to be freely oscillated up and down by providing the elastic members while they are revolvingly displaced whereby changing a spring constant in the load input direction depending on car speed. CONSTITUTION:In a parallel link type rear suspension, the links 2 and 3 of a front wheel extending in the car width direction are adapted to secure a rear wheel 1 to the member 5 on a car body side via elastic members in such a way as to be freely oscillated up and down. The structure is constituted to be such that a spring constant in the load input direction from the links is changed by revolving the elastic members 7, which are provided respectively for the mounting sections of each link 2 and 3 to the member 5 on the car body side, around the oscillating center of the links. And displacement in revolution of said elastic members 7 is effected through a link mechanism 11 with an electric motor 9 actuated. And the electric motor 9 is controlled by a controller 20 receiving the output from a car speed sensor 19 in such a way that the spring constant of a rear side elastic member 7 is made lower than that of a front side elastic member 7 in case of running at high speed. |
