摘要： An apparatus and method is provided for measuring the caster angle of a steerable wheel assembly without contact with the vehicle. An image capture device, preferably a CCD type video camera or sensor, views a vehicle wheel mounting and steering assembly that is illuminated by a light source. Information from the captured image is transmitted to a computer based control, such as a computer or processor, that determines the angle of a preformed line or preselected physical features on the wheel assembly in the captured image, and determines the caster angle of the steering axis based on the fixed angular relationship of the line or physical features to the steering axis that is stored or accessed by the control. Preferably, the image capture device is mounted below the vehicle on a vehicle alignment machine that supports the vehicle.

摘要： A compact, modular and versatile vehicle testing assembly for testing at least the brakes of an assembled vehicle comprises a pair of rollers adapted to support a tire of a tire and wheel assembly of a vehicle positioned on the testing assembly, with the pair of rollers being moveable relative to one another to alter the spacing there between. A drive system is connected to one of the rollers to operate as a drive roller for selectively imparting rotational motion to a tire of a vehicle tire and wheel assembly, with the other roller comprising a freewheeling roller to which rotational motion is imparted by a vehicle tire. A brake member is engageable with the freewheeling roller to selectively inhibit rotation of the freewheeling roller.
