Description of the Related Art As a rear wheel suspension system for a front-wheel drive vehicle, left and right wheel support members are connected by a torsion beam, and both ends of this torsion beam are rigidly connected to the other end of a trailing arm whose one end is pivotally attached to a vehicle body. A known torsion beam suspension system is known. In this type of suspension system, the trailing arm alone cannot secure sufficient lateral rigidity.Therefore, for example, connect the right end of the vehicle body and the left end of the torsion beam with a lateral member called a Panhard rod. Is common.

好ましいことではない。However, in this type, since the Panhard rod is attached asymmetrically, when the torsion beam moves up and down together with the wheels and the Panhard rod turns in a vertical plane, the vehicle body and the axle are relatively laterally displaced. Will cause. This is not preferable because it adversely affects straight running stability.

う。Further, the lateral force input to the wheels becomes a component force that is transmitted through the Panhard rod to lift or sink the vehicle body. However, since the influence of this component force varies depending on the turning direction, left and right The turning characteristics become uneven.

It swings in a vertical plane with the connecting end with the vehicle body 5 as a fulcrum.
Therefore, the ends of the two lateral rods 6 connected to the torsion beam 1 are displaced in the left-right direction when viewed from the plane (dimension r in FIG. 2). This displacement is absorbed by the turning movement of the connecting link 8 in the horizontal plane (see FIG. 3). Since both lateral rods 6 are symmetrically extended with respect to the center of the vehicle body, the behavior of the vehicle body becomes uniform regardless of the lateral force at the time of turning acting from either the left or right direction, and the lateral rods do not shift to one side.
