ABSTRACT:
The axial load of the mechanically spring-supported drive axle of a lifting axle structure aggregate is defined by a compression of a respective suspension spring and the pressure of the lifting bellows. A two-dimensional contour is disposed at a signal body which determines for each disposition of the rotary angle the position of a first end piece of a tappet, which position of the end piece of the tappet represents a value corresponding to the axial load signal to be obtained. The two-dimensional contour is employed to engage the tappet and deliver a distanace signal. The tappet is shiftable in a direction disposed parallel to its axis based on the contour curve of the cam. The tappet is also shiftable based on the spring support. The setting of the position of the a second end piece (26) of the tappet (22, 24, 26) is superposed to a setting of the position depending on the tappet length by the contour (20, 21).
