  • 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.

  • Patent number: 4365685
    Abstract: Equipment influencing the jacknifing angle of an articulated motor vehicle, when the vehicle units are in articulated coupling with each other, has a hydraulic piston device with two working spaces arranged outside the longitudinal centerline of the motor vehicle, the piston of which is connected to one unit, while its cylinder is connected to the other vehicle unit. Each working space is connected through a hydraulic valve unit to the hydraulic space of the hydropneumatic energy source, the valve unit has a parallel connected check valve and choke valve closing from the direction of the working space toward the hydropneumatic energy source. An adjustable transfer cross sectional closing element of the choke valve is in functional connection with the sensor element sensing the steering angle and direction of the front axle and the actuating signal of the sensor element is concomitant with the position of one of the choke valves bringing about increased choking.
