Abstract
An air spring for damping and controlling a level position of a driver's cab or of a motor vehicle includes a lid, a rolling piston and at least one air spring bellows. At least one damping device is integrated into the air spring. A level control system is integrated into the air spring and is configured to at least one of supply and discharge compressed air, gas or a compressible medium so as to control the level position of the driver's cab or of the motor vehicle.
Claims14
An air spring for damping and controlling a level position of a driver's cab or of a motor vehicle, the air spring comprising:
- a lid;
- a rolling piston;
- at least one air spring bellows;
- at least two damping devices integrated into the air spring;
- and
- a level control system integrated into the air spring and configured to at least one of supply and discharge compressed air, gas or a compressible medium so as to control the level position of the driver's cab or of the motor vehicle,
- wherein the level control system comprises a compressed-air inlet device configured to supply the compressed air, gas or the compressible medium, and a compressed-air outlet device configured to discharge the compressed air, gas or the compressible medium, and
- wherein the inlet valve is integrated into the rolling piston.
An air spring for damping and controlling a level position of a driver's cab or of a motor vehicle, the air spring comprising:
- a lid;
- a rolling piston;
- at least one air spring bellows;
- at least one damping device integrated into the air spring;
- and
- a level control system integrated into the air spring and configured to at least one of supply and discharge compressed air, gas or a compressible medium so as to control the level position of the driver's cab or of the motor vehicle,
- wherein the at least one damping device includes a first damping device having a first chamber with a variable volume, a second chamber whose volume remains constant and a first damping channel device connecting the two chambers with each other.
An air spring for damping and controlling a level position of a driver's cab or of a motor vehicle, the air spring comprising:
- a lid;
- a rolling piston;
- at least one air spring bellows;
- at least one damping device integrated into the air spring;
- and
- a level control system integrated into the air spring and configured to at least one of supply and discharge compressed air, gas or a compressible medium so as to control the level position of the driver's cab or of the motor vehicle,
- wherein the level control system comprises a compressed-air inlet device configured to supply the compressed air, gas or the compressible medium, and a compressed-air outlet device configured to discharge the compressed air, gas or the compressible medium,
- wherein the compressed-air outlet device has at least one outlet valve and a valve control device, and
- wherein the valve control device has a compression spring and a control rod connected to the compression spring.
