1. An axle-lifting device for lifting an axle of a vehicle, comprising:
a function mechanism for generating a force component in an axle-lifting direction, wherein the function mechanism is a bellows and is configured to generate the force component in the axle-lifting direction having a first force component to provide a first functionality and having a second force component in the axle-lifting direction to lift the axle; wherein the function mechanism includes a separating piston, wherein a variation in at least one of an internal fluid pressure and an internal fluid quantity distribution in the function mechanism causes a displacement in a resting position of the separating piston, the force component in the axle-lifting direction being generated as a function of the displacement, wherein a load state is proportional to the fluid pressure to provide direct control of the axle-lifting device, wherein the function mechanism is configured to provide another force component against the axle-lifting direction for providing the first functionality, wherein the function mechanism is configured as the bellows having a shock absorber, the first functionality being a shock-absorbing effect of the shock absorber and the first force component being a shock-absorbing force of the shock absorber, wherein the shock absorber houses the separating piston and is configured to induce the second force component by the displacement of the resting position of the separating piston, and wherein the bellows is connected to a chassis of the vehicle and to one end of a suspension arm, which is opposite the other end of the suspension arm, which is connected to a trestle connected to the chassis. |
