Problems solved by technology

However, when the side frame swings laterally, the existing lateral limit device of the pendulum bogie is in rigid contact, and the high resistance protection for the fully compacted lateral impact is not enough, and the improvement of the lateral motion performance is limited, resulting in damage to the wheel wear

Abstract

The invention discloses a transverse elastic limiting device and a bogie. The transverse elastic limiting device comprises a swing bolster assembly, a lower swing assembly and a central spring assembly. The swing bolster assembly comprises a swing bolster body, and swing bolster cylinders are arranged at the two ends of the bottom of the swing bolster body respectively. The lower swing assembly comprises a spring supporting plate, and spring trays arranged corresponding to the swing bolster barrel are arranged at the two ends of the top of the spring supporting plate respectively. The top of the central spring assembly is installed in a swing bolster barrel of the swing bolster assembly, and the bottom of the central spring assembly is installed in a spring tray of the lower swing assembly. The bottom of the swing bolster body is further provided with two first transverse elastic stoppers which are symmetrically arranged. The top of the spring supporting plate is further provided with two second transverse elastic backstops arranged corresponding to the first transverse elastic backstops. According to the transverse elastic limiting device, the rigidity between the side frame and the swing bolster is enhanced, the side frame is prevented from transversely moving, the transverse flexibility of the vehicle is improved, and the transverse dynamic performance of the vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of bogies, in particular to a transverse elastic limiting device and a bogie. Background technique [0002] Freight car bogies generally adopt three-piece bogies, which are mainly composed of side frames, bolsters, wheelsets, wedge damping devices, foundation braking devices, anti-diamond devices, and side bearings. Compared with the traditional three-piece bogie, the oscillating bogie has greatly improved lateral motion performance, especially the wheel-rail lateral force and the lateral running quality of the car body. [0003] The existing pendulum bogie realizes the lateral spacing through the lower stop on each side of the bolster and the stop of the spring support plate. However, when the side frame swings laterally, the existing lateral limit device of the pendulum bogie is in rigid contact, and the high resistance protection for the fully compacted lateral impact is not enough, and the improvement o...
