Abstract:

An improved motorcycle suspension system comprising a substantially straight torsion bar having a first end and a second end; a rear wheel axle support attached rotatably and pivotally to the motorcycle frame; means for holding the first end of the torsion bar fixed to prevent rotation thereof; a multiplying linkage for reversibly converting a substantially vertical motion of the rear wheel axle support caused by irregularities in the surface over which the motorcycle is ridden into a torque applied to the second end of the torsion bar causing the torsion bar to provide a progressively larger opposing torque in reaction to the applied torque and requiring progressively more force to apply an equivalent torque to the torsion bar for progressively larger upward misplacements thus damping the motions of the rear wheel axle support. A tension winder is attached to the torsion bar adjacent to the first end of the torsion bar to provide a means for adjustably twisting the torsion bar controlling thereby the damping of the motions of the rear wheel axle support.

Abstract:

A hydraulic shock absorber for a motorcycle employs a jacket which surrounds the damping chamber of the shock absorber. The damping chamber contains damping fluid and a damping piston for providing reciprocating axial damping displacement in accordance with axial forces exerted on a shaft connecting the damping piston. The jacket forms an annular outer chamber. Fluid circulates through the outer chamber to stabilize the temperature of the damping fluid in the damping chamber. The outer chamber is connected for fluid communication with the cooling system of the vehicle engine.
