Abstract

The invention provides a traction device, a bogie and a vehicle. The traction device comprises a traction beam, an elastic traction piece and a traction pin. The elastic traction piece is mounted on the traction beam and used for being connected with a frame of the bogie. The traction pin is mounted on the traction beam and used for being connected with a vehicle body and comprises a box body part and a pin body part which are connected mutually. The traction pin is connected with the traction beam through the pin body part and connected with the vehicle body through the box body part. According to the traction device, the problem that a traction device in the prior art is complex is solved.

Description

technical field [0001] The invention relates to the field of rail vehicles, in particular to a traction device, a bogie and a vehicle. Background technique [0002] The existing traction device usually has a traction rod. The traction device with this structure has many parts, the production process is complicated, and the assembly time is relatively long. In addition, the traction device has a complicated structure and many parts, so that its weight is relatively heavy. [0003] In order to further realize the lightweight design requirements of urban rail bogies, it is necessary to simplify the structure of the bogie traction device and reduce the weight of the traction device. Contents of the invention [0004] The main purpose of the present invention is to provide a traction device, a bogie and a vehicle to solve the problem that the structure of the traction device in the prior art is relatively complicated. [0005] In order to achieve the above object, according t...
