Abstract

A multipurpose construction vehicle bears on its vehicle frame, which is realized as an axle-link pivot or center pivot type, a front swing loading device and a rear-mounted excavator. The swing loading device is permanently connected above the front axle (3) to a front subframe (22) which forms part of the vehicle frame, and the rear-mounted excavator is permanently connected to a rear subframe (32) which is connected to the rear axle (5) and forms part of the vehicle frame, both subframes (22, 32) being connected to one another at a suitable point along the longitudinal center axis of the vehicle by means of a self-aligning bearing (34) which can swivel about this longitudinal axis to a limited degree and by means of cylinders arranged at a distance from the self-aligning bearing on both sides, so that the two subframes can be locked with respect to one another at any desired swivel position. By means of wheel load sensors on the front axle or rear axle and via control devices, in each case the cylinder on that side of the vehicle with the greater wheel load can be actively supplied with pressure as a function of the difference between the measured wheel loads on both sides (FIG. 5).
