LOCOMOTIVE AXLE MOUNTED CAB SIGNALING SENSOR LOCOMOTIVE AXLE MOUNTED CAB SIGNALING SENSOR

摘要

A sensing device mounted on a railway locomotive vehicle axle assembly to sense signalling currents conducted through the axle. The device also serves to protect the critical traction motor support bearing from contamination by foreign substances. The device comprises mounting means at least partially covering the bearing and maintaining a core member in position encircling the axle. The core member conducts magnetic flux caused by the flow of current through the axle. Sensing means associated with the core member detect the presence of the flux. Securing means maintain the mounting means in position about the axle.
