Abstract
The present invention is drawn to a structure for supporting suspension arms connected with a wheel supporting member on a vehicle body having a main frame and a side sill, which extend in the longitudinal direction of the vehicle body side by side. The structure includes a bracket which pivotally supports a swing arm on the main frame and the side sill, whereby load on the swing arm is distributed to the main frame and the side sill. And, the rigidity of the vehicle body is improved by the connection of the main frame to the side sill with the bracket.
Claims14
In a vehicle having a vehicle body, and front and rear wheels rotatably supported on the vehicle body, a suspension system comprising:
- a main frame connected to the vehicle body and extending longitudinally of the vehicle body;
- a side sill connected to the vehicle body, disposed at a lower part of the side of the vehicle body between the front and rear wheels of the vehicle body, located outwardly of said main frame with respect to the widthwise direction of the vehicle body, and extending longitudinally of the vehicle body;
- a wheel supporting member connected to the vehicle body, one of the wheels being rotatably mounted to said wheel supporting member;
- a support bracket extending transversely of and connected to said main frame and said side sill;
- and
- a swing arm extending longitudinally of the vehicle body, having first and second end portions, pivotally supported by said support bracket at said first end portion and connected to said wheel supporting member at said second end portion.
A rear wheel suspension system for a vehicle comprising:
- a main frame extending in the longitudinal direction of the vehicle;
- a sub-frame extending longitudinally along said main frame and attached thereto;
- a side sill extending longitudinally along said main frame between a front wheel and a rear wheel of the vehicle, said side sill being located outwardly of said main frame and laterally spaced therefrom;
- a wheel supporting member for rotatably supporting a wheel;
- a plurality of laterally extending suspension arms pivotally connected at opposite ends to said wheel supporting member and said sub-frame;
- a transversely extending support bracket connected at one end to said main frame and at an opposite end to said side sill;
- and
- a swing arm connected at a forward end to said support bracket and at a rearward end to said wheel supporting member, said swing arm extending longitudinally between said main frame and said side sill for pivotally supporting said wheel supporting member relative to said support bracket.
