Embodiment Construction

[0058] figure 1 A schematic plan view of a bogie 1 is shown in FIG. 1 , including part of a device 2 for fault monitoring of chassis components of a rail vehicle according to a first embodiment of the invention.

[0059] The bogie 1 is arranged rotatably about a vertical axis of rotation 36 relative to a car (not shown) and includes a bogie frame 4 by means of a secondary spring, also not shown, since it is not essential for the invention The system is supported on the carriage of the rail vehicle.

[0060] The bogie frame 4, on the other hand, is supported via a primary spring arrangement on four wheel bearing housings 6, 8, 10, 12, in which each wheel bearings 14, 16, 18 and 20 are mounted for supporting an axle 22, 24, the axle supports two wheels 26 at the end. A total of two axles 22 , 24 are present for each bogie 1 .

[0061] For monitoring the bogie 1 and its components 4 to 20 a device 2 for fault monitoring is provided, wherein the figure 1 and figure 2 Only ...

Abstract

The invention relates to a device (2) for monitoring errors in undercarriage components of rail vehicles, having at least one acceleration sensor (28, 28', 28'') which works with an evaluation unit (32). At least one acceleration sensor (28, 28', 28'') is arranged on the undercarriage of the rail vehicle in such a manner that its direction of detection (30, 30', 30'') has at least one component parallel to the vertical axis (z-direction) of the rail vehicle. The invention proposes that the acceleration sensor (28, 28', 28'') is constructed in such a manner that it delivers a measuring signal which contains the signal portion corresponding to a ground acceleration, or represents a signal corresponding to a ground acceleration, and that the evaluation unit (32) has a routine for testing functions of the acceleration sensor (28, 28', 28''), the routine controlling an error signal if the measuring signal delivered by the acceleration sensor (28, 28', 28'') contains no signal portion corresponding to a ground acceleration. The routine also suppresses the error signal if this is not the case.

Description

technical field [0001] The invention relates to a device and a method for fault monitoring of chassis components of rail vehicles. Background technique [0002] Monitoring systems for chassis are obtained in rail vehicle traffic of increasing importance. On the one hand, these monitoring systems are required to be normative or compliant for safety reasons. By way of example the following systems are listed here, which are European-wide requirements for high-speed trains in terms of TSI (Technical Specification for International Operability - Official Journal of the European Union): [0003] On-Boad-System for derailment detection, [0004] On-board systems for detection of hot parts or identification of bearing damage, [0005] On-board system for the identification of instability or damaged shock absorbers. [0006] Chassis monitoring systems on the other hand are used for diagnosis and early identification of damaged components, critical conditions or other failures in...
