    摘要: A suspension assembly (10) for mounting a wheel assembly (14) to any wheel position of a vehicle, the suspension assembly (10) being pneumatically controlled to adjust both the ground clearance of the vehicle and its wheel-track width, the suspension (10) assembly also being mountable at any wheel position whether the wheel at that position is to be steerable or nonsteerable. The suspension system includes upper (20) and lower (22) control arms connected between a frame (12) attachable to the vehicle and a kingpin assembly (18) to provide a parallelogram linkage. It also includes at least one pneumatically actuated linear actuator (24) to control the angular disposition of the lower control arm (22) with respect to the frame and thereby control the ground clearance and wheel-track width of the vehicle. The parallelogram geometry provides the upper (20) and lower (22) control arms with at least 120 degrees of angular travel. When in a stowed position, the control arms are nearly vertical and fit, with the kingpin (18), within a space effectively equal to that occupied by the linear actuators (24) and the frame (12). The disposition of the suspension assembly components is such that wheels are drivable with wheel-mounted electric drives (52), inboard-mounted electric drives (74), or a conventional engine drive.

    摘要: A suspension system for the ground engaging powered wheels (3) and/or caster wheels (4) of a power wheelchair (1) comprises three links, two of which (6) are universally pivotally connected between the frame (2) of the wheelchair (1) and a wheel mounting transaxle housing or subframe (5) so that the wheels (3) can tilt relative to the frame (2) of the wheelchair (1) in a vertical plane. A third link (7) is connected between the vehicle frame (2) and the wheel mounting structure which can only pivot in a vertical plane, thus restraining the wheels (3) from any lateral displacement relative to the vehicle frame (2). Fluid cylinders (13, 13) operable between the links (6, 7) and the vehicle frame (20) provide cushioning of the frame (2) and also, by subtraction of fluid from the fluid cylinders (13), can lower the entire frame of the wheelchair (2) relative to the ground engaging wheels (3) to permit the wheelchair (1) and occupant to drive into the side door opening of a conventional van.
