Abstract

The invention discloses a wireless sensor wheel set bearing device for a railway vehicle. The wireless sensor wheel set bearing device obtains a power supply and a transmission signal by utilizing a wireless coupling mode. The wheel set bearing device can perfectly solve the problem that an existing cable is prone to breaking down, and the interface of the sensor module is kept consistent with the current design.

Description

technical field [0001] The present application relates to the technical field of bearings, in particular to a wireless sensor wheel set bearing device for rail vehicles. Background technique [0002] In view of the development trend of high technology and safety considerations, wheel set bearing devices equipped with temperature sensors and speed sensors have become almost standard configurations for subways and high-speed trains. With the help of these sensors, the state of each bearing can be continuously monitored, so that the occurrence of bearing failure can be predicted or detected in time and measures can be taken at a given time, thereby avoiding the catastrophic consequences that may result from bearing failure and enhancing the safety of rail vehicles. safety. [0003] Currently, the solution for wheel set bearing units equipped with temperature and speed sensors is to integrate the temperature sensor, speed sensor and sealing cover into one body. Wherein, the wh...
