Embodiment Construction

[0037] figure 1 and figure 2 An air spring damper 10 according to the invention is shown arranged between a load bearing portion (not shown) and a connecting rod 76 of a commercial vehicle.

[0038] The air spring damper 10 has a rolling piston 12 according to the invention, an end element 14 and an air spring bellows 16 . In particular, as figure 2 As shown, the air spring bellows 16 is connected at a first free end 18 to the rolling piston 12 and at a second free end 20 to the end element 14 in order thus to form a fluid-filled working space 22 .

[0039] In the present case, the terminal element 14 is configured as a flat plate with a collar portion 23 for fastening the second end 20 and with a support portion 24 for supporting the bearing portion. The second end 20 is clamped to the collar portion 23 by the clamping ring 21 . Furthermore, the terminal element 14 is provided with connection means 26 for connecting a fluid source (not shown). The pressure in the worki...

Abstract

The invention relates to a rolling piston (12) for an air spring damper (10) in the field of commercial vehicles, comprising a piston part (28) and a container part (32) having a hollow design and being fluidly connected to each other and a cover element (34), which is connected to the container part (32) to form an additional volume container (36).

Description

technical field [0001] The invention relates to a rolling piston for an air spring damper in the commercial vehicle sector. Furthermore, the invention relates to an air spring damper with a rolling piston of this type. Background technique [0002] Air springs or rolling leaf springs are used to suspend two vehicle parts that are movable relative to each other, but are also used to change the ride height position of the vehicle. In order to form a gas-tightly closed working space, this type of air spring has an air spring bellows made of rubber and connected to an upper terminal element, usually in the form of a plate, and a rolling piston. During compression and rebound, the rolling vane rolls on the outer surface of the rolling piston. Furthermore, the connection of the air spring to vehicle parts such as support arms or linkages takes place via rolling pistons. [0003] In addition to the aforementioned suspension function, it is also possible to design the air spring ...
