Abstract

The embodiment of the invention provides a bogie and a railway vehicle, and the bogie comprises a framework; the framework comprises two side beams extending in the longitudinal direction and a cross beam arranged between the two side beams. The wheel pairs are arranged below the two ends of the side beams; the wheel pair comprises an axle, wheels symmetrically arranged on the axle and an axle box. A traction device; the traction device comprises a first traction pin and a second traction pin which are rotationally connected, and the first traction pin is matched with the cross beam to transmit longitudinal force; the first traction pin and the second traction pin are respectively used for being connected with two adjacent carriages; the primary suspension device is arranged between the end part of the side beam and the axle box; and the secondary suspension device is arranged on the framework. The bogie and the railway vehicle provided by the embodiment of the invention are beneficial to reducing the self weight of the vehicle and improving the traction efficiency.

Description

technical field [0001] The present application relates to vehicle running technology, in particular to a bogie and a rail vehicle. Background technique [0002] Rail vehicles are an important transportation link connecting cities, and have gradually become the main means of transportation in cities. Rail vehicles are also the main carrier for cargo transportation. A rail vehicle mainly includes: a car body and a bogie arranged under the car body. The bogie is used to carry the car body and realize the running and steering functions. [0003] In the traditional scheme, two bogies are arranged at the bottom of a carriage, and the number of bogies in the vehicle is twice the number of carriages, so that the weight of the vehicle itself is relatively large. Contents of the invention [0004] In order to solve one of the above-mentioned technical defects, an embodiment of the present application provides a bogie and a rail vehicle. [0005] According to a first aspect of an e...
