Arrangement for limiting uncontrolled articulation movements at a pivot between vehicle units

摘要

An arrangement in articulated vehicles for avoiding uncontrolled articulation movements between participating vehicle units. A transducer, sensing instantaneous speed of at least one driven vehicle wheel on the trailing vehicle unit, sends a signal in response thereto to a comparator circuit where the signal is compared with a reference signal representing a normal value for the wheel speed. If a predetermined speed difference is indicated, the comparator circuit activates means such as an operating power control means and/or an articulation brake, for limiting the articulation movement.
