Abstract

The invention provides a bogie of a railway vehicle and the railway vehicle. The bogie of the railway vehicle comprises two sets of wheel pairs, load bearing saddles arranged on the rotation shafts of the wheel pairs, and side frames arranged on two load bearing saddles at the same side. Elastic pads are arranged between the load bearing saddles and the side frames. The elastic pads are distributed around the upper surface and the side surface of the load bearing saddles. The bogie with the elastic pad structure having certain angle and large deflection can significantly enhance the curve negotiation performance of the bogie, reduce the abrasion of the wheel, realize the low driving power effect of the wheel track, and reduce the damage to the route.

Description

technical field [0001] The invention relates to a railway vehicle manufacturing technology, in particular to a railway vehicle bogie and a railway vehicle. Background technique [0002] Rail transit is an important mode of transportation in my country, and the railway freight car bogie is an important component of the railway freight car. As the loading requirements of railway wagons are getting higher and higher, in order to ensure the stability of the wagons and reduce the damage to the railway tracks, the requirements for the bogies of railway wagons are also getting higher and higher. [0003] The K2 type railway freight car bogies commonly used in the prior art generally include wheelsets, bearing saddles and side frames, wherein the bearing saddles are mounted on the bearing outer edges of the wheelsets, the side frames are mounted on the bearing saddles, and the two opposite sides The frame is fixedly connected by the lower cross support device to connect the front a...
