Problems solved by technology

[0006] In the known steering wheel design, which uses multiple sliding plates GLP on the gas spring LUF for emergency operation in the event of gas spring LUF failure, its lateral stiffness is almost completely eliminated, so the wagon body WKA in the case of sliding friction hysteresis Lateral movement cannot be determined
[0007] This means that the upper and lower bezels BF1, BF2 can assume any undetermined position relative to each other in the case of lateral sliding friction hysteresis (Fig. 3), so that the rideability of the rail vehicle SFZ will degrade or destroy the admissible bounding shape

Embodiment Construction

[0031] according to Figure 4 , a rail vehicle SFZ based on the present invention has a steering wheel DRE and a wagon body WKA arranged on it. An inflatable spring LUF according to the invention is arranged between the wagon body WKA and the steering wheel, under the inflatable spring is an emergency spring NOT, for example a rubber membrane spring. In the event of failure of the gas-filled spring LUF, the emergency spring NOT makes the longitudinal spring suspension of the wagon body WKA, and in order to limit the maximum lateral deviation, a centrally arranged pin ANS is provided, whose lateral deviation is controlled by the two transverse buffers QPU, QPU' limit.

[0032] As shown in FIG. 6, the gas-filled spring LUF according to the present invention has two opposite bladders BF1, BF2, which are connected to each other by an air bladder LBA. Such gas-filled spring LUF or gas-filled spring systems are known to experts in many different forms, so no more detailed explanati...

Abstract

A pneumatic spring (LUF) for a rail vehicle (SFZ), comprising two bellow rims (BF 1 , BF 2 ) mounted one above the other and interconnected by pneumatic-suspension bellow (LBA). One of the bellow rims (BF 1 ) comprises a groove (NUT) and the other rim (BF 2 ) comprises a counterpart (GGS) for the groove (NUT), which permit an automatic centering of the two bellow rims (BF 1 ,BF 2 ) in relation to one another in the transversal direction (Q) of the vehicle, if the pneumatic spring (LUF) fails.

Description

field of invention [0001] The invention relates to a gas-filled spring for rail vehicles, which has two bellows, one of which is arranged on top of the other and which are connected to each other in the assembled state by means of an airbag. [0002] The invention further relates to a rail vehicle having a steering wheel or bogie and a wagon body arranged thereon. Background technique [0003] A gas spring LUF of the type mentioned at the outset is usually arranged between the steering wheel DRE and the wagon body WKA of a rail vehicle SFZ. Arrangements of gas springs known from the prior art may be shown by way of example in FIG. 1 . The spring LUF can of course also be filled with a gaseous medium other than air. This is why the term "gas spring" in this article is quite commonly referred to as a gas spring. [0004] The known gas-filled spring LUF has an air bellows LBA which is arranged between two bellows BF1 , BF2 , usually made of steel. The inflatable spring LUF ...
