Embodiment Construction

[0022] figure 1 An embodiment of a device 1 according to the invention is schematically shown in , which has an air spring 2 comprising two parts and fixed on figure 1 on bogies that are not visible in . The carriage body, also not shown, is supported on air springs 2 , wherein, in addition to a primary spring system, for example consisting of coil springs, the air spring 2 is arranged on the bogie to provide a spring and damping effect for the carriage body.

[0023] The air spring communicates via a compressed air line 3 with a compressed air source 4 which is only schematically shown in the figure. The weight or load of the vehicle body is detected by the measuring sensor 5, whereby the pressure in the air spring can be determined. By means of said pressure, the load of the pushed-out carriage can be returned. An air spring valve 6 is provided for regulating the pressure and volume of compressed air in the air spring 2 , wherein the air spring 2 is evacuated via the inle...

Abstract

A device (1) having a pneumatic spring (2) for supporting a load on a bogie of a rail vehicle having a compressed air supply (4) which is pneumatically connected to the air spring (2) via an air spring valve (6) in order to vent and to fill the air spring (2) with compressed air, and having a control unit which is designed to adjust the air volume and / or the air pressure in the air spring (2), a compressed air line (3) making available the pneumatic connection between the compressed air supply (4), air spring (2), air spring valve (6) and control unit - in which unnecessary filling and venting of the air spring (2) is prevented, means are proposed for limiting the volume flow (7) into the compressed air line (3) as a function of the speed of the rail vehicle.

Description

technical field [0001] The invention relates to a device with an air spring for supporting a load on a bogie of a rail vehicle, a source of compressed air connected pneumatically to the air spring via an air spring valve for use in for emptying or filling the air spring with compressed air; and an adjustment unit for adjusting the air volume and / or air pressure in the air spring, wherein the air spring is charged and emptied via at least one compressed air line . [0002] The invention also relates to a method for regulating the air pressure and the air volume of an air spring of a rail vehicle, wherein the regulating unit is directed to an air spring valve which communicates with the air spring and with a source of compressed air, at least one of which compresses the air Lines are provided for inflating and emptying the air spring. Background technique [0003] Such devices and such methods are known from the usual prior art. Accordingly, the springs of passenger rail ve...
