  • Patent number: 4494765
    Abstract: The invention relates to an anti-jackknifing device for an articulated motor vehicle, mainly for an articulated bus, where the torque influencing the jackknifing angle is brought about by a friction brake mechanism around the articulated coupling. The anti-jackknifing device has sensor elements sensing the run-dynamic characteristics connected to a control unit that controls the brake actuating unit of the brake mechanism. One of the elements of the friction brake mechanism braked in relation to each other is connected to one of the two or three vehicle units coupled to each other--i.e. front vehicle, trailer and intermediate vehicle unit--while the other element is connected to at least one of the further two vehicle units. One of the friction elements of the friction brake mechanism according to the invention is formed as brake rod connected to one of the vehicle units, the other friction element i.e.
