TECHNICAL FIELD

[0001] The utility model relates to the field of rail vehicles, concretely is a kind of transverse stop for rail vehicle bogie. BACKGROUND

[0002] Transverse stop is an important component in the secondary suspension system of rail vehicle, usually connected by vulcanization process by base, rubber, wear-resistant plate etc., and the transverse stop of rail vehicle is a mechanical device installed between bogie and car body, and its structure design closely surrounds the demand of ensuring the safe and stable operation of rail vehicle.

[0003] Transverse stop plays a key role in the operation process of rail vehicle, when rail vehicle is running, due to the unevenness of track, curve driving and the interference of various external forces, vehicle will produce lateral displacement and vibration, the main role of transverse stop is to limit the lateral relative displacement between car body and bogie, prevent car body from excessive inclination or deviating from track center line, so as to ensure the safe operation of vehicle, when the lateral displacement between car body and bogie reaches the set threshold, the contact parts of transverse stop will interact, and the further expansion of displacement is limited by rigid blocking.

[0004] Due to the differences between various urban rail line operation conditions and design requirements, and the overrunning of rail vehicle, the existing transverse stop is easily subjected to great impact force of car body, which causes the damage of transverse stop, and seriously affects the running quality of urban rail vehicle. UTILITY MODEL CONTENTS
