Abstract
An apparatus is provided for raising and lowering a vehicle that is supported by a wheel suspended from a frame of the vehicle by a suspension component. The apparatus includes a linear actuator that is vertically oriented to move the wheel of the vehicle relative to the frame of the vehicle. A compression device is arranged to compress the suspension component of the vehicle in response to movement of the wheel by the linear actuator.
Claims18
An apparatus for raising and lowering a vehicle that is supported by a wheel suspended from a frame of the vehicle by a suspension component, said apparatus comprising:
- a linear actuator that is vertically oriented to move the wheel of the vehicle relative to the frame of the vehicle;
- a compression device arranged to compress the suspension component of the vehicle responsive to the movement of the wheel by the linear actuator;
- and
- wherein the linear actuator comprises (i) a base portion configured to attach at the suspension component and (ii) a movable portion movably coupled with the base portion and configured for mounting the wheel.
An apparatus for raising and lowering a vehicle that is supported by a wheel suspended from a frame of the vehicle by a suspension component, said apparatus comprising:
- a linear actuator that is vertically oriented to move the wheel of the vehicle relative to the frame of the vehicle;
- a compression device arranged to compress the suspension component of the vehicle responsive to the movement of the wheel by the linear actuator;
- and
- wherein the compression device comprises a flexible connector attached between the linear actuator and the frame of the vehicle.
An apparatus for raising and lowering a vehicle that is supported by a wheel suspended from a frame of the vehicle by a suspension component, said apparatus comprising:
- a linear actuator having a base portion configured to attach at a suspension component of the vehicle and a movable portion operably coupled with the base portion and configured to mount a wheel;
- and
- a flexible connector having a first end attached at the movable portion of the actuator and a second end configured to attach at the frame of the vehicle, wherein the flexible connector engages a coupling configured to be disposed at the suspension component;
- wherein the linear actuator is operable to generally vertically move the wheel toward the chassis to a first lowered position, and wherein, when the flexible connector is placed in tension, the suspension component is compressed toward the chassis to move the wheel further toward the chassis to a second lowered position.
A system for raising and lowering a vehicle that is supported by a wheel suspended from a frame of the vehicle by a suspension component, said system comprising:
- a linear actuator attached at the suspension component of the vehicle, wherein the linear actuator comprises a movable portion that supports the wheel;
- a flexible connector attached between the movable portion of the actuator and the frame of the vehicle, wherein the flexible connector is movably engaged with a coupling disposed at the suspension component;
- wherein the linear actuator is operable to generally vertically move the wheel assembly toward the frame to a first lowered position, and wherein the linear actuator is operable to place the flexible connector in tension to compress the suspension component to move the wheel assembly further toward the frame to a second lowered position.
