Abstract

A pulley assembly for raising and lowering an associated vehicle body is provided. A pulley assembly for raising and lowering an associated vehicle body includes a housing including an outer sleeve extending along an axis. At least one top pulley is operably connected to the outer sleeve, and at least one bottom pulley is operably connected to the outer sleeve and is movable relative to the at least one top pulley along an axis. The cable is interwoven between the at least one top pulley and the at least one bottom pulley. An actuator is operably connected to the cable to reel in the cable and pull the at least one top pulley toward the at least one bottom pulley to lower the associated vehicle body. The actuator further releases the cable to allow the at least one top pulley to move away from the at least one bottom pulley to raise the associated vehicle body.

Description

technical field [0001] The present invention generally relates to a pulley assembly for raising and lowering the height of a vehicle. Background technique [0002] It is often beneficial to adjust the height of the vehicle body. For example, by raising the body to an extended position or lowering it to a retracted position, ground and roof clearance can be adjusted, allowing driving in conditions that would otherwise not be possible or desirable. Devices that facilitate such adjustments are traditionally provided in or around the suspension struts of motor vehicles. Typically, such devices comprise a lifting housing arranged on a central axis, the lifting housing defining a chamber. A support tube is disposed in the chamber, wherein the lift housing is movable relative to the support tube along the central axis. Movement of the lift housing is typically driven using hydraulic actuators. While these hydraulic actuators provide the functionality described above, there are ...
