ABSTRACT:
A vehicle travels along a rail and, driven by an onboard motor. The vehicle includes an auxiliary guide wheel mounted in a floating arrangement on a component acted upon by a helical spring. A shaft on which the wheel is mounted is disposed in an elongated slot in a lever. The lever is articulated at a place on the vehicle body and its other end is acted upon by a second spring. Rotation of the lever is limited by a stop which is secured to the vehicle. When the auxiliary guide wheel makes contact with the guide rail, the two springs are compressed, so that the two wheels touch. Consequently, contact between the outer peripheral surfaces of the two wheels occurs only when the vehicle is moving underneath the guide rail. At other times during operation, there is no contact and no wear on the material forming the outer peripheral surfaces of the two wheel.
