Patent ID: 8262100

Claim:
A vehicle height adjustment suspension device for raising and lowering a supported portion of a frame of a vehicle relative a ground surface upon which a wheel of the vehicle connected to a wheel section frame below the supported portion is disposed and dampening force shocks received at the wheel, the device comprising: a suspension assembly having a shock absorber including a cylinder containing fluid for connection on a bottom cylinder end of the cylinder to the wheel section frame, and a piston rod defining an axis and extending into the cylinder with a piston housed therein, and a spring mounted proximal a top rod end of the rod and proximal the bottom cylinder end and coiled around the cylinder and rod; a threaded screw rotatably mounted in a housing top of a housing, the housing top being connected to the supported portion, the screw extending along said axis into a threaded portion, adjacent said top rod end, of a screw channel extending into said rod along said axis; and a motor connected to the threaded screw for rotating the screw in opposing first and second directions to move the assembly and wheel connected thereto and the housing top and frame connected thereto, respectively away from and towards one another between a raised configuration distal one another, the supported portion being thereby higher relative the ground surface, and a lowered configuration proximal one another, the supported portion being thereby lower relative the ground surface, the assembly dampening said shocks when said device is in said raised configuration, said lowered configuration and between said raised configuration and said lowered configuration.
