Abstract

A device for measuring axle geometry at the wheel axles of motor vehicles with the wheels turning. The device has at least two frames. A driven pair of rotating cylinders is positioned in each frame. A wheel of the vehicle can rest on the cylinders. The frame can rotate freely in a horizontal plane around a pivot that is positioned away from the pair of cylinders along the length of the vehicle. The frame can also slide freely on the base plate in a direction parallel to the longitudinal axis of the vehicle. A sensing component can be placed against the side of the wheel. The sensing component has a goniometer that measures the position of the sensing component against the wheel and compares it to a reference that is fixed with respect to the device. '
