Abstract
A vehicle lift assembly having an input shaft, a first ball screw coupled to rotate with the input shaft, a ball screw nut coupled to a first bracket and configured to selectively move a lifting member based on rotation of the first ball screw, and a power unit coupled to the input shaft, the power unit having a wireless transponder and configured to be selectively powered based on wireless signals received by the transponder from a remote device.
Claims5
A vehicle lift assembly, comprising:
- an input shaft;
- a first ball screw coupled to rotate with the input shaft;
- a ball screw nut coupled to a first bracket and configured to selectively move a lifting member based on rotation of the first ball screw, the first bracket coupled to a first ball bearing nut such that rotary motion of the first ball screw moves the first bracket to raise or lower a first support;
- and
- a power unit coupled to the input shaft, the power unit having a wireless transponder and configured to be selectively powered based on wireless signals received by the transponder from a remote device;
- and
- an anti-reversing locking mechanism comprising a clutch that selectively prevents the lifting member from lowering unless a torque is input through the input shaft
- a first gear box configured to transfer rotary motion from the input shaft to a first output coupled to the first ball screw and a second output coupled to a second ball screw;
- a first lift base and a second lift base each having slots defined longitudinally along inner walls;
- and
- a second bracket coupled to a second ball bearing nut such that rotary motion of the second ball screw moves the second bracket to raise or lower a second support.
