A wave gear apparatus comprises a spline having top, bottom, exterior, and interior surfaces. A plurality of spline teeth extend from the interior surface toward a center axis. A wave generator is rotatably disposed in the spline. A belt assembly extends about the wave generator and includes a plurality of belt teeth extending radially outwardly, whereby a total number of the belt teeth is less than a total number of the spline teeth. An output member defines a recess receiving the wave generator and the belt whereby, in response to a rotational movement from the wave generator, the output member rotates in a direction same or opposite of the wave generator. A bearing assembly is disposed between the wave generator and the belt assembly and includes a plurality of needles each extending parallel to the center axis. A vehicle lifting system including the wave gear apparatus is also disclosed herein.

A valve assembly for an air spring includes a body having an opened end disposed in communication with a first tank and a closed end. The body defines a cavity separated by a divider into an upper and a lower portion. The body defines at least one upper orifice in communication with the cavity and a second tank; and at least one lower orifice in communication with the cavity and a third tank. An actuator is disposed in communication with the first, the second, and the third tank. The actuator is rotatable from a first position wherein the actuator is in communication with the first tank alone to a second position allowing communication between the first and the second tank, a third position allowing communication between the first and the third tank, and a fourth position allowing communication between the first, the second, and the third tank.

Rotating three way valve for switchable air springs

An air suspension assembly includes a top and a piston. A bellows connects the top and the piston defining a first chamber. The piston includes an upper portion defining a bore in communication with the first chamber. A body extends outwardly from the upper portion to a proximal end defining a second chamber. A decoupler is disposed in the bore in communication with the first chamber and the second chamber. The decoupler includes a partition member extending across the decoupler isolating the first chamber from the second chamber for changing pressure in response to a pressure applied to the air suspension assembly. The decoupler includes a cap portion disposed in the bore, defining a hole, and an extension portion extending outwardly from the cap portion to a distal end defining a third chamber in communication with the hole, the first chamber, and the second chamber to receive the partition member.

Air suspension assembly

The invention provides for a power steering apparatus comprising of a housing that extends along a longitudinal axis. A rack is disposed within the housing and supported for movement along the longitudinal axis by a bearing. A pinion supported by the housing is in meshing engagement with the rack. The bearing disposed around the rack includes a wall of a continuous varying radial thickness that circumferentially surrounds the rack. An adjustment device supported by the housing is connected to the bearing and rotatably adjusts the bearing relative to the longitudinal axis. The continuous varying radial thickness of the wall positions the rack as the bearing is rotated by the adjustment device relative to the pinion ensuring proper meshing engagement between the rack and the pinion.
