Document Type and Number:
WIPO Patent Application WO/2019/019781
Kind Code:
A1
Abstract:
An axle box structure having both anti-slip and monitoring functions for a railway vehicle, comprising: an axle box body (1) sleeved, by means of a bearing, on the axle end, an axle box gland (6) fixed outside the axle end, and a gear (7) fixed on the exterior end of the axle box gland (6); an axle box cover (8) is fixed on the exterior end of the axle box body (1), and a speed sensor mounting interface (19) away from the center of a bogie and a signal sensor mounting interface (20) close to the center of the bogie are provided in the axle box cover (8). Observed from the axle end, an angle a is formed downward between the central line of the speed sensor mounting interface (19) and the horizontal line, and an angle b is formed downward between the central line of the signal sensor mounting interface (20) and the horizontal line, the value range of angle a being 7°-11°, and the value range of angle b being 8.5°-11.5°. Said axle box structure keeps the dimensions of a labyrinth groove of the axle box cover (8), at the position cooperating with the axle box body (1), unchanged, and enables a boss interface for an anti-slip device and a boss interface for a signal device to be integrated on the axle box cover (8), thereby realizing the purpose that both an anti-slip device and a signal device can be mounted on one axle box cover (8).
