Device for controlling the drawbar load for multi-axle trailers

The device has one or more axles (I,II) of a trailer (1), which are lifted or lowered by a computing unit depending on the loading- or driving situation of the trailer, such that the drawbar load remains constant in the predetermined boundaries. The height position of the front axle of the trailer is variable for adjusting the drawbar load. The computing unit is operatively coupled with hydraulic components of the front axle for the trailer with a chassis.
