Abstract: An air spring includes a closing member, a rolling piston, and an air spring bellows connected to the rolling piston and the closing member to form a fluid-filled pressure chamber. A level control system for supplying and/or discharging fluid may be integrated into the pressure chamber to control level position based on air spring stroke. The level control system may have a control valve and an actuator connected to the control valve. The actuator may include a guide tube coupled to the rolling piston or closing member, and movably arranged within the pressure chamber. An actuating member may include a pin member and may operate the control valve. A compression spring may have a central spring and a biasing spring, and the guide tube may include a control flange coupled to the pin member, and the biasing spring may be supported to press the pin member against the control valve.

Abstract: An air spring for a motor vehicle or a driver's cab of a motor vehicle has a cover, a rolling piston and at least one air spring bellows. At least two damping devices are integrated into the air spring.

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.

Abstract: An air spring includes a rolling piston having a fastening section. An air spring bellows has at least a first one-sided bead portion and a buffer element. The first bead portion bears against an outer side of the fastening section. The buffer element is fixed onto the outer side of the fastening section via a snap-lock connection.

Abstract: An air spring assembly or air spring damper with an integrated valve control for controlling a level position of a vehicle or of a driver's cab includes a rolling tube, a lid and an air spring bellows which together delimit a pressure chamber with compressed air. A control valve includes an actuation device for feeding compressed air into the pressure chamber or for discharging compressed air from the pressure chamber. A compression spring device has a first end operatively connected to the rolling piston or the lid and a second end operatively connected to the actuation device. The compression spring device is configured with at least two parts including a central spring facing towards the rolling piston or the lid and a control valve biasing spring facing towards the control valve. The central spring is biased to a greater extent than the control valve biasing spring.

Abstract: A pneumatic spring for utility vehicles comprising a rolling bellows and a rolling piston. The rolling bellows has at least one bead-like plug-on edge. The rolling piston is of unipartite form and includes an interior space constantly exchanging air with an air chamber enclosed by the rolling bellows. At the plug-on edge, the rolling bellows has a sealing bead with an inelastic bead core for connection to the rolling piston. The fastening of the plug-on edge to the rolling piston, with position securing action and sealing action, is disposed on an inner side of a rolling piston edge.

Abstract: An air spring attachment system for motor vehicles. The air spring attachment system includes at least one air spring and at least one link for the suspension of a wheel on a chassis. The air spring attachment system also includes a plug-in connection connecting the air spring to the link.

Abstract: An air spring for a vehicle with a lifting function includes an upper rolling piston and a lower rolling piston disposed opposite to each other. A rolling bellows encloses a compressed air space and has double rolling folds. The pressure effective surfaces of the rolling folds are coordinated with each other in such a manner that, during dynamic spring operation of the air spring over a predetermined spring travel, the pressure effective surface of the rolling fold on the lower rolling piston is larger than the pressure effective surface of the rolling fold on the upper rolling piston.
