  • Patent number: 5306034
    Abstract: A suspension system for connecting a wheel mount to a frame of a vehicle wherein the wheel mount is provided with a rigid extension above the wheel spindle on the wheel mount extending into proximity of the chassis and overlapping the chassis, the linkages connected between the end of the rigid extension and the frame using parallel pin means at each end. Both the extension and the linkage may be made double or otherwise more rigid. A second generally horizontal linkage is connected by similar parallel rotation-permitting pins at one end to the wheel support and at the other to the frame. Suspension systems are usually symmetrical so that wheels on opposite sides of the frame are connected by similar linkages.
