Abstract:
1. A device for simulating slip of a wheel on a vehicle test bench according to the equation F R =F A ×C, wherein F R is a frictional force, F A is a contact force of the wheel, and C is a coefficient of friction, the device comprising: a movable test surface to simulate rolling conditions of a wheel which contacts said test surface with a contact force F a lifting and lowering device changing the contact force F a wheel adapter operable to couple said lifting and lowering device to said wheel while the wheel is mounted on a vehicle and so as to rotate with said wheel relative to said lifting and lowering device, whereby said wheel is tested in a mounted location on the vehicle; a bearing unit rotatable about a pivot axis extending transversely to an axis of rotation of the wheel adapter so as to change the track of the wheel, the wheel adapter being rotatably arranged in and coupled to the bearing unit; a mount pivotably mounted to joint blocks; a plurality of connecting arms connecting the bearing unit to the mount, said lifting and lowering device comprising
