ABSTRACT:
A device for testing vehicle wheels, tires, hubs, bearings and bolts therr under service-like load conditions, includes (a) a mounting device for fastening a vehicle wheel in a rotatable manner and for swivelling the latter into different camber angles; (b) a drum, which is disposed in such a manner around the vehicle wheel that the vehicle wheel may, via a tire situated thereon, be brought into rolling contact with the inner peripheral surface of the drum; (c) a vertical or radial loading device, which for applying a vertical or radial force onto the mounting device is connected to the latter; (d) a lateral or axial loading device for applying a lateral or axial force acting in the lateral or axial direction of the vehicle wheel, the lateral or axial loading device for applying the lateral or axial force onto the mounting device being connected to the latter; (e) at least one ring, which is disposed on the inner peripheral surface of the drum and arranged as a stop ring adjacent to the tire and the flank of the vehicle wheel; and (f) a device for rotating the drum; the vertical or radial loading device and the lateral or axial loading device each being independently connected in an articulated manner to the mounting device, wherein the mounting device is supported in such a displaceable manner that the vehicle wheel, for automatic camber adjustment, is capable of swivelling about the wheel contact point.
