A tire inflation system comprising a tire inflation apparatus having an inflation head, a pressurized gas source, and a controller, with the inflation head being positioned at a tire and wheel assembly inflation location at which a tire and wheel assembly is received to inflate the tire and wheel assembly. The tire and wheel assembly includes a tire pressure monitoring (TPM) valve stem that detects and transmits inflation pressure data of the tire and wheel assembly. The inflation head defines a tire inflation cavity that seals with the tire of the tire and wheel assembly when engaged with the inflation head. Pressurized gas is delivered from the pressurized gas source through an outlet in the tire inflation cavity for inflation of the tire and wheel assembly. The controller receives inflation pressure data from the TPM valve stem and controls operation of the tire inflation apparatus in response thereto.

Modular tire inflator

A tire inflation apparatus for inflating a tire mounted on a rim comprises an inflation head mounted to a moveable inflation shaft of a head position cylinder and an assist cylinder mounted to a frame member, with the frame member and assist cylinder positioned above the inflation location. The assist cylinder includes a moveable assist shaft operatively connected to the inflation shaft by a moveable cross member whereby the head position cylinder and assist cylinder cooperatively operate to selectively position the inflation head. The inflation head is positioned in a retracted position by vertical upward extension of the assist shaft and positioned in a tire engaging position by vertical downward retraction of the assist shaft. A fluid passage in the inflation shaft may deliver pressurized gas into a tire inflation cavity of the inflation head for inflating a tire when the inflation head is sealed against the tire.

A vehicle toe set adjustment device and method for adjusting a vehicle tie rod includes an adjustment head adapted to be received over a tie rod. The adjustment head includes a surface for engaging a tie rod fastener, a plurality of moveable collet keys mounted on the adjustment head, and a drive member engaging surface. An actuator on the adjustment head moves the collet keys to engage the tie rod after the tie rod is received in the adjustment head. A method is also provided for engaging moveable collet keys on an adjustment head to engage the tie rod for rotation of the tie rod to adjust the toe set of a vehicle wheel. The device and method are useful with a variety of tie rod assemblies on various vehicles having different sized tie rod assemblies.

An apparatus for determining wheel assembly alignment comprises a contact assembly, a light source, and a light beam receiving assembly. The contact assembly engages the wheel assembly to define a plane of orientation of the wheel assembly and the light source projects a beam of light with respect to the contact assembly. The light beam receiving assembly receives the light beam and forms an image of the light beam indicating the orientation of the wheel assembly with respect to a predetermined position. The receiving assembly may include a Fresnel lens for directing the received light beam to a target and a camera device for imaging the light beam on the target, with the camera device adapted to provide toe and camber information of the wheel assembly based on the location at which the light beam impinges upon the target. The contact assembly may be pressed against the wheel assembly without being secured thereto.

A vehicle testing apparatus for subjecting a vehicle to a compound force includes a support disposed in a plane for supporting the vehicle, and a mechanism coupled to the support for moving the support along at least one of three perpendicular axes. The mechanism subjects the vehicle to the compound force resulting from simultaneous movements along any combination of the axes. The mechanism includes a first platform constrained for rectilinear movement along a first axis, and a second platform constrained for rectilinear movement along a second axis, with the support preferably also being movable along a third axis. The support preferably also includes actively or passively controlled contact surfaces in all three axes with an optional trip mechanism. In addition, a first actuating device is preferably coupled to the first platform and a second actuating device is preferably coupled to the second platform.
