Abstract

The embodiment of the invention provides a traction device, a bogie and a railway vehicle, the traction device comprises a first traction pin and a second traction pin which are rotationally connected, and the sides, deviating from each other, of the first traction pin and the second traction pin are used for being connected with two adjacent carriages correspondingly; the first traction pin is matched with the cross beam to transmit longitudinal force. According to the traction device, the bogie and the railway vehicle, the self weight of the vehicle is reduced, and the traction efficiency is improved.

Description

technical field [0001] The application relates to vehicle running technology, in particular to a traction device, 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 technical defects, an embodiment of the present application provides a traction device, a bogie and a rail vehicle. [0005] According to th...
