Abstract
The present invention relates to a suspension system in a vehicle body assembly which is used in common for a four-wheel-steering vehicle and a two-wheel-steering vehicle. In the present invention, a front suspension system installed in a four-wheel-steering vehicle is set to have a higher lateral rigidity than when installed in a two-wheel-steering vehicle, so that the front suspension system can withstand the lateral forces acting on the front wheels of the four-wheel-steering vehicle, said lateral forces being larger than those in a two-wheel-steering vehicle. Further, the suspension system is set to have a lowered rigidity against rolling of the vehicle body where it is installed in a four-wheel-steering vehicle, whereby the riding comfort can be maintained as that of the two-wheel-steering vehicle. In addition, a front steering mechanism installed in a four-wheel-steering vehicle is set to have a steering ratio which is smaller than where it is installed in a two-wheel-steering vehicle, by which even when the rear wheels are steered in the same direction as the front wheels, the four-wheel-steering vehicle can be handled in the same manner as the two-wheel-steering vehicle.
