ABSTRACT:
A suspension system for a vehicle having frame, a wheel and a movable support for said wheel is disclosed. The suspension system comprises a first shock absorbing member functionally connected to the wheel support. The first shock absorbing member is connected in parallel to a first spring means which is also connected to the wheel support. The first spring means and first shock absorbing member are connected in series to a second shock absorbing member which in turn is functionally connected to the vehicle frame. A second spring means, preferably having a lower spring stiffness than said first spring means, is employed in a parallel configuration with said second shock absorbing member and can either be in parallel with said first shock absorbing member and first spring means or in series with these latter elements.
The first shock absorbing member further contains upper and lower fluid chambers separated by a piston for further control. As a preferred embodiment, the second shock absorbing member also contains upper and lower fluid chambers for altitude control.
