Abstract
A vehicle suspension system which uses a beam spring capable of substantial elastic deformation in two planes to provide for independent wheel suspension and to commonize suspension mounting systems in a vehicle chassis.
Claims21
An automotive suspension system comprising:
- a chassis;
- a beam spring capable of substantial, elastic deformation in at least two planes, said beam spring having a first and second end, said beam spring further fixedly attached on said first end to said chassis, whereby said beam spring provides suspension to said chassis through substantial, elastic deformation in said at least 2 planes of said beam spring between said first end and said second end of said beam spring, and;
- a wheel end attached to said beam spring, whereby said wheel end is capable of mounting a road wheel.
An automotive suspension system comprising:
- a chassis;
- a beam spring capable of substantial, elastic deformation in at least two planes, whereby said beam spring provides suspension to said chassis through substantial, elastic deformation in said at least 2 planes of said beam spring between a first suspension point and a second suspension point on said beam spring, said beam spring having a first end and a second end, further wherein said beam spring is attached to said chassis at said first suspension point and said second suspension point, and;
- a wheel end attached to said beam spring, whereby said wheel end is capable of mounting a road wheel.
A system comprising:
- a frame member;
- a suspension member having a first longitudinal section and at least other longitudinal section, wherein said first longitudinal section is less stiff than said at least one other longitudinal section, said suspension member capable of substantial, elastic deformation in at least two orthogonal planes, and further having a first end and a second end, and;
- a fitting attached to said suspension member, said fitting capable of rotatably attaching to a wheel.
