The present invention relates to a device for continuously regulating the erection of a tandem axle of a vehicle or a self-moving working machine having a vehicle frame and at least one drive axle, wherein a tandem drive axle with a movable tandem axle housing is respectively disposed at the ends of the drive axle, and the torque introduced by the drive axle is mechanically distributed to the wheels disposed in the tandem axle housing through the drive tandem axle. Therein, the drive axle is coaxially connected to the drive tandem axle through a ball ramp device, wherein the ball ramp device is comprised of a first ball ramp disk connected to an end of the drive tandem axle opposing an end of the drive axle, and a second ball ramp disk disposed in an axially displaceable manner at the end of the drive tandem axle, and the distance L between the second ball ramp disk and the first ball ramp disk is increased by a torque of the drive tandem axle counteracting the drive torque, wherein the second ball ramp disk is operatively connected to a piston, and a pressure with a value of P 1 is produced in a volume by the axial movement of the second ball ramp disk, wherein P 1 is passed to a control valve, and the control valve controls the level of a system pressure P 3 or P 4 depending on P 1 , and a resulting pressure with the value of P 2 serves for controlling a compensating device for achieving a compensating torque counteracting the erection effect. The invention further relates to a method for continuously regulating the erection of a tandem axle of a vehicle or a self-moving working machine.
