Abstract

The invention discloses an integral hoisting fusion traction device and a railway vehicle. The traction device comprises a traction seat, a traction rod assembly, a traction connecting seat, a central pin bush and a cover plate; a center pin is arranged on the lower portion of the traction base and connected with the center pin sleeve through the cover plate. One end of the traction rod assembly is hinged to the traction connecting seat; the traction connecting seat is of an integrated structure, an integral lifting seat and a transverse shock absorber mounting seat are arranged on the traction connecting seat, a central pin bush mounting hole is formed in the central position of the traction connecting seat, the central pin bush penetrates through the central pin bush mounting hole, and the central pin bush is arranged on the central pin in a sleeving manner; the outer ring of the central pin bush is pressed on the inner hole of the traction connecting seat. The traction device is simpler in structure.

Description

technical field [0001] The invention relates to an integral lifting fusion traction device and a rail vehicle, which belongs to the field of rail vehicles and is especially suitable for A-type subways. Background technique [0002] The traction device is a key component connecting the bogie and the car body in urban rail vehicles. Its main functions are: 1. To adapt to the rotation of the bogie relative to the car body; 2. To transmit traction and braking forces. [0003] At present, the traction devices used in urban rail vehicle bogies mainly have two structural forms, which are generally divided into Z-shaped double-tie-rod traction devices and single-tie-rod traction devices. Among them, the Z-shaped double pull-rod traction device is a low-position traction device. For example, the traction device disclosed in China Utility Model Patent No. CN201610149U includes a traction seat and a traction connection seat. One end of the double traction rod is connected to the tracti...
