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.
