Title:
ANTI-DERAILING DEVICE FOR RAIL VEHICLE BOGIE AND RAIL VEHICLE BOGIE
Document Type and Number:
WIPO Patent Application WO/2017/063315
Kind Code:
A1
Abstract:
An anti-derailing device for a rail vehicle bogie of the present invention comprises at least one mounting base (1) mounted at the bottom of a rail vehicle bogie (9). The mounting base (1) is provided with an anti-derailing sliding plate (2) stretching to ground rails (8). Transverse positioning and vertical-direction stretching length of the anti-derailing sliding plate (2) on the mounting base (1) simultaneously meet the following requirements: 1), the anti-derailing sliding plate (2) is located at the inner side of the ground rails (8) when a rail vehicle runs normally; 2), when at least one wheel set (6) of the rail vehicle climbs on rail, the anti-derailing sliding plate (2) will interact with the ground rails (8) to form transverse limiting junctures to limit the freedom degree of the rail vehicle, so that the rail vehicle is still restrained by the ground rails (8). The anti-derailing device of the present invention can avoid derailing of a rail vehicle bogie during operation, and in particular, can avoid derailing probably occurring after a wheel set climbs on rail, so that train safety and transporting efficiency are improved.
