VEHICLE WITH ONE FRONT AXLE AND AT LEAST TWO SUSPENDED REAR AXLES

Abstract: for a vehicle with a front axle () and at least two suspended rear axles (), a level relative to the roadway can be adjusted by t controlling pressurized suspension elements () arranged on the rear axles (), where the rear axles () are each driven electrically by an electric motor () controlled by at least one control unit (). a separate transmission () with a shifting element that operates with interlock is associated with each rear axle (), and at least one control device () is associated with the rear axles (). the control device is designed to detect the occurrence of a shifting process at one of the rear axles (), and as a function of the occurrence of the shifting process, to reduce the pressure of the pressurized suspension elements () of the rear axle () being shifted and to increase the pressure of the pressurized suspension elements () of the other rear axle ().
