ABSTRACT:
The axial load of the mechanically spring-supported drive axle of a lifting axle structure aggregate is defined by the compression of the suspension spring and the pressure of the lifting bellows. A two-dimensional contour of a signal body is employed to engage a signal pin. The signal pin is axially shiftable based on the pressure and rotatable based on the spring support. A two-dimensional contour (20, 21) is disposed at the signal body. The shiftability of the stator (25) of the distance path sensor (24) is provided depending on the pressure of the lifting bellows (1). The pressure-dependent setting of the immersion depth is superposed to the setting of the immersion depth of the signal pin (22) by the contour (20, 21).
