摘要： A method for controlling an air suspension system of a vehicle includes: a) determining a bellows pressure-time characteristic curve for air admission to and release from the bellows of one air spring or the bellows of a plurality of air springs, the characteristic curve being normalized with the value of a supply pressure in a reservoir for compressed air, b) sensor measurement of a current pressure in the spring bellows of the air springs as well as the current supply pressure immediately before air admission thereto or air release therefrom, c) determining, from the normalized characteristic curve, the opening duration for the associated shutoff valve using the ratio of the measured bellows pressure to the measured supply pressure and the ratio of the provided target pressure to the measured supply pressure, d) opening the associated shutoff valve for the determined opening duration in order to set the provided target pressure.

摘要： A compressed air supply installation for operating an air suspension installation of a vehicle includes an air supply unit configured to supply air, an air compression unit configured to compress air, a bleeding line, and a compressed air supply line. The bleeding line includes a bleeding valve arrangement in the form of a controllable solenoid valve arrangement comprising a magnetic part and a pneumatic part actuatable directly via the magnetic part, and a bleeding port for bleeding air. The compressed air supply line includes an air dryer, and a compressed air port for supplying the pneumatic installation with compressed air. The pneumatic part is open in an unactivated state of the magnetic part of the solenoid valve arrangement. The pneumatic part is open in a branch line of the compressed air supply line between a pressure-side valve port and a control-side valve port of the branch line.

摘要： A regenerative shock absorber that include a housing and a piston that moves at least partially through the housing when the shock is compressed or extended from a rest position. When the piston moves, hydraulic fluid is pressurized and drives a hydraulic motor. The hydraulic motor, in turn, drives an electric generator that produced electric energy. The electric energy may be provided to a vehicle, among other things. The regenerative shock absorber may also provide ride performance that comparable to or exceeds that of conventional shock absorbers.

摘要： A gas spring assembly includes a first end member and a second end member spaced from the first end member. A flexible wall extends between the first end member and the second end member such that a spring chamber is at least partially defined therebetween. A biasing assembly is operative to urge an end of the flexible wall into abutting engagement with the second end member and operative to permit the end of the flexible wall to be separated a distance from the second end member while in the assembled condition. A gas suspension system is also included.
