A method for regulating the level of a vehicle body of a motor vehicle, and level control system of a motor vehicle

摘要

The present invention relates to a method for controlling the level of a vehicle body of a motor vehicle and to a level control system of a motor vehicle for controlling the level of a vehicle frame with air springs (1), which, by means of valves (3) with a pressure reservoir (4) can be connected or the environment, so that compressed air from an air bellows (2) of the air springs (1) can be discharged and can be lowered, the level of the vehicle body, and wherein the level of the vehicle body is lifted, in that a of an electric motor (5) driven compressor (6) from the environment draws in air and the air bellows (2) of the air springs (1) is acted on by compressed air or by a pressure reservoir (4) with the interior of the bellows (2) of the air springs (1) is connected with compressed air and these.The present invention provides that during the raising of the vehicle body with the aid of the pressure accumulator (4) the compressed air via a turbine (7) which is connected in the generator mode with the electric motor (5) is connected and electrical energy is generated. In addition, the invention provides that the compressed air during the lowering of the vehicle body via the turbine (7) is guided and electrical energy is generated. By means of the invention, the energy, which contain in the compressed air is effectively used.
