Abstract

A lifting system for generating a lifting force on a portion of a vehicle includes a vehicle wheel and a force-generating mechanism structured to be received inside a rim cavity of the wheel. The force-generating mechanism is also structured to be operably connected to a frame of a vehicle. A bearing member is operably connected to the force-generating mechanism. The bearing member is structured to transmit a force generated by the force-generating mechanism to a surface in physical contact with the bearing member. The bearing member is also structured for operably connecting the wheel to the force-generating mechanism. Force applied by the force-generating mechanism may be sufficient to lift a portion of the vehicle off of a ground surface, or the force may only be sufficient to apply a parking brake force without lifting the vehicle.

First claim

What is claimed is:

1. A system for generating a lifting force on a portion of a vehicle, the system comprising:
a vehicle wheel;
a force-generating mechanism structured to be operably connected to a frame of a vehicle; and
a bearing member operably connected to the force-generating mechanism and structured to transmit a force generated by the force-generating mechanism to a surface in physical contact with the bearing member,
the bearing member also being structured for operably connecting the wheel to the force-generating mechanism,
the system being structured so that the bearing member is enabled to physically contact a ground surface when the system is mounted on a vehicle and the wheel is connected to the force generating mechanism along a first side of the bearing member.

2. The system of claim 1 further comprising
a processor; and
a memory communicably coupled to the processor and storing a control module including instructions that when executed by the processor cause the processor to, responsive to a parking brake control command, control operation of the force-generating mechanism to lower the bearing member toward a ground surface on which the vehicle resides until a predetermined level of bearing force is applied to the surface.

3. The system of claim 1 further comprising
a processor; and
a memory communicably coupled to the processor and storing a control module including instructions that when executed by the processor cause the processor to, responsive to a lifting control command, control operation of the force-generating mechanism to move the bearing member into contact with a ground surface and generate a force sufficient to lift the portion of the vehicle to a location spaced apart from the ground surface.

4. The system of claim 3 including instructions that when executed by the processor cause the processor to, responsive to the lifting control command, and prior to controlling the force-generating mechanism to move the vehicle wheel toward the ground surface, control operation of a vehicle transmission to shift the transmission to a parking mode.

5. The system of claim 1 further comprising:
a processor; and
a memory communicably coupled to the processor and storing a control module including instructions that when executed by the processor cause the processor to, responsive to a wheel access control command, control the force-generating mechanism to move the vehicle wheel toward a ground surface to a location spaced apart from the ground surface.

6. The system of claim 1 further comprising a housing structured for attachment to the frame and structured to receive the wheel therein, the housing defining an opening structured to receive the vehicle wheel therein and to face in a direction toward the ground surface when the housing is attached to the frame.

7. The system of claim 1 wherein the vehicle wheel has a rim defining a rim cavity, and wherein the bearing member is connected to the force-generating mechanism inside the rim cavity.

8. The system of claim 7 wherein the force-generating mechanism is structured to push the bearing member against the rim to force the wheel into contact with a ground surface during operation of the force-generating mechanism.

9. The system of claim 1 wherein the bearing member is connected to the force-generating mechanism along an exterior of the rim cavity.

10. The system of claim 1 , structured so that the bearing member is prevented from physically contacting a ground surface when the wheel is connected to the force generating mechanism along a second side of the bearing member opposite the first side.
