Embodiment Construction

[0028] according to figure 1 The air spring arrangement consists essentially of an outer tube 1 with an upper retaining ring 2 opposite a rolling tube 3 with a corresponding lower retaining ring 4 . The fastening ring 4 is here a component part of a hydraulic damper 5 which is coaxially surrounded by the outer tube 1 and the roller tube 3 . An air spring bellows made of elastomer material extends between the outer tube 1 and the rolling tube 3 , which air spring bellows expand on the outer surface of the rolling tube 3 according to the air spring travel. A pressure chamber 7 is formed by the outer tube 1 , the rolling tube 3 and the air spring bellows 6 , which is acted upon with compressed air, thereby fulfilling the air spring function of the air spring arrangement. In order to pressurize the pressure chamber 7 , an internal control valve 8 is provided, which here is designed as a 3 / 3-way directional valve and has switching positions, namely exhaust, closed and inlet.

Abstract

The invention relates to an air spring arrangement having at least one integrated control valve (8) for charging a pressure chamber (7), which is formed between an outer tube (1), a rolling tube (3) and an air spring bellows (6) which connects said tubes, with compressed air, wherein the control valve (8), which has a plurality of switching positions, can be actuated by means of likewise integrated mechanical actuating means as a function of the air spring stroke for the purpose of ride height adjustment, wherein the mechanical actuating means comprises a compression spring (10) which is fastened on the end side to the outer tube (1) or rolling tube (3), the distal end of which compression spring interacts with an actuating plunger (9) of a control valve (8) which is arranged opposite on the rolling tube (3) or outer tube (1) respectively.

Description

technical field [0001] The invention relates to an air spring arrangement with at least one integrated control valve for charging a pressure chamber formed between an outer tube, a rolling tube and an air spring bellows arranged between the outer tube and the rolling tube with compressed air, In this case, the control valve can be actuated by means of a likewise integrated mechanical actuating element for level adjustment as a function of the air spring stroke with a plurality of switching positions. Background technique [0002] The field of application of the invention extends in particular to automotive technology. For example, in the context of the chassis of commercial vehicles, shock absorbers are used which comprise mostly hydraulic damping elements and a gas spring arrangement interacting therewith. In the sense of an integrated design, the damping element usually has a container tube, which is connected to the rolling tube of the air spring, wherein the rolling tub...
