Abstract

The invention discloses an air spring fault detecting system. Detection for air spring faults is realized by connecting an air spring pressure switch and an electric level detecting unit; according to difference of pressure intensity in an air spring air path, a movable contact of the air spring pressure switch is closed with a first stationary contact or a second stationary contact, so that electric level signals detected by the electric level detecting unit are different; and the electric level detecting unit emits fault signals according to the electric level signals. According to the scheme disclosed by the invention, electric level signals detected by the electric level detecting unit are different according to changes of pressure intensity in the air spring, so that different fault signals are emitted to judge that whether the air spring has faults or not, and therefore, an urban rail vehicle has an air spring fault detecting function.

Description

technical field

[0001] The invention relates to the field of fault detection, in particular to an air spring fault detection system and an urban rail vehicle air spring detection system. Background technique

[0002] At present, the secondary suspension devices of urban rail vehicles usually use air springs. During the operation of the train, when the air spring fails and cannot be inflated, the comfort of the train will be affected.

[0003] At present, most of the urban rail trains do not have the air spring fault detection function, and the fault detection of the air springs on the bottom of the urban rail trains cannot be realized, so that the faults of the air springs cannot be solved in time. Contents of the invention

[0004] In view of this, the present invention provides an air spring fault detection system to solve the problem that urban rail trains do not have the air spring fault detection function in the prior art. The specific scheme is as follows:
