  • System for limiting relative angular movement between the tractor and semi-trailer
    Patent number: 5135248
    Abstract: A system and method for blocking a relative angular movement between a semi-trailer and a traction vehicle so as to limit the angular movement to a predetermined angle. A lock of a locking system in a guide plate is inserted in a central angle of a fifth wheel that supports the semi-trailer. The lock is electro-pneumatically actuated by an electric signal signifying brake actuation. This prevents an involuntary angular movement between the semi-trailer and the tractor from taking place mainly upon actuation of the brakes because of an imbalance occurring between friction forces acting on the tires.
