Tracking device for a vehicle with rubber tires has a guard rail and guide wheels to maintain contact with the vehicle's steering device

摘要

A guard rail (2) has a groove (3) stretching lengthwise in one of its side edges. Linked to a guide wheel's (1) non-rotating mounting, a curved arm (4) engages in a groove (3). The guide wheel has an active link with this groove on a guard rail so that the guide wheel can slide sideways with only little play.
