An axle box structure compatible with two speed sensors

Abstract

The present invention discloses an axle box structure compatible with two speed sensors, which relates to the technical field of locomotive axle box structures. The present invention includes a bearing seat and a bearing cover. Grooves are machined in the bearing seat and the bearing cover. The bearing seat and the bearing cover are fixedly connected by bolts and jointly enclose a bearing installation cavity. A car axle and a bearing are installed in the bearing installation cavity, and the bearing is sleeved on the car axle. A speed measurement gear is installed at the end of the car axle through a fastening bolt. Moreover, a fork lever interface is provided on the disc of the speed measurement gear, and a Hall sensor is radially and matchingly installed on the speed measurement gear, and / or a fork speed sensor is axially arranged on the speed measurement gear. The present invention has installation interfaces for two speed sensors, can be compatible with two speed sensors, and provides more sensor selection schemes for locomotive users.
