Embodiment Construction

[0054] Figure 1a A part of a first exemplary embodiment of an air spring module is shown, which is known to comprise a shock absorber 2 and an air spring 1 for vibration isolation and damping of the chassis of a motor vehicle, preferably In a motor vehicle, the first end can be fixed relative to the body and the second end can be fixed to the wheel suspension. The air spring 1 comprises an air spring cover 3 fixed relative to the vehicle body, a first end of a rolling airbag 5 , which is fastened gas-tight to the air spring cover by means of a clamping element 4 , the coil The dynamic bladder at least partially delimits a first working or pressure chamber 6 filled with compressed air. The second end of the rolling airbag 5 is airtightly connected to the rolling piston 7 . The rolling airbag 5 can roll on this rolling piston 7, which is connected to the cylinder tube 8 of the shock absorber 2, wherein the cylinder tube 8 is preferably fixed to the shock absorber fork 9 of the...

Abstract

An air spring module including an air spring and a shock absorber for springing and damping vibrations of a motor vehicle chassis, including—at least two working chambers filled with compressed air and connectable via at least one valve, an air spring cover, a rolling bellows fixed to the air spring cover in an air-tight manner and at least partly delimits a first working chamber filled with compressed air, and a rolling piston, which is fixed to a cylindrical tube of the shock absorber and on which the rolling bellows rolls. A second and a third working chamber are arranged one above the other in the rolling piston so as to surround the cylindrical tube. The working chambers are separated from each other by an intermediate floor provided in the rolling piston and can be connected to the first working chamber via switchable valves arranged in the rolling piston.

Description

technical field [0001] The invention relates to an air spring module comprising a shock absorber and an air spring for damping and damping vibrations of the chassis of a motor vehicle, the air spring module having at least two working parts filled with compressed air chamber, said working chamber can be connected by at least one valve; an air spring cover plate; an airtight rolling airbag fixed on the air spring cover plate, said rolling airbag at least partially delimiting a first compressed air-filled working chamber; rolling piston fixed on the cylinder tube of the shock absorber and on which the rolling airbag rolls. Background technique [0002] In the basic known having a plurality of volumes (volume and V 1 to V i ) In the air spring module of the working chamber, the total air spring volume is divided into individual volumes (Vgesamt=∑V i ). [0003] Thus, for example, an air spring with two working chambers is available from DE 102 00 632 A1, in which a second w...
