Bogie

Abstract

The invention provides a bogie which comprises a bogie framework and a wheel set assembly. The bogie framework is arranged on the wheel set assembly which comprises an axle and wheels. The two ends ofthe axle are connected with wheel seats of the wheels, and a driving device is arranged on the bogie framework and used for transmitting control signals output by a control device of a locomotive tothe wheel set assembly to drive the wheels to rotate. The bogie further comprises a hydraulic control device, a damping assembly, a grounding device, a traction rod and a braking assembly. All components of the bogie provided by the invention are compact in structure and reasonable in layout, the effects of locomotive automatic centering and self-guiding are achieved, and thus the bogie has good transverse comfort and anti-snaking capacity when travelling on a straight route and a curve.

Description

technical field [0001] The invention relates to the technical field of railway vehicle manufacture and assembly, in particular to a bogie. Background technique [0002] In the field of railway vehicle manufacturing and assembly technology, the multi-articulated 100% low-floor modern tramcar has a relatively low purchase cost, so its application range is relatively wide. The bogie is the most important part of the multi-articulated 100% low-floor modern tram, which supports the car body, bears and transmits various loads and forces from the car body to the wheel pair or from the wheel rail to the car body , to further distribute the axle load evenly. Ensure the safe operation of the vehicle, and flexibly run along the straight line and pass the curve smoothly. [0003] Most of the commonly used multi-articulated bogies are produced abroad. For example, Flexity 2 is a new generation of 100% low-floor trams launched by Bombadier. The biggest feature of FLEXXUrban 3000 is the...

AI Technical Summary

Problems solved by technology

[0005] In order to solve at least one of the problems mentioned in the background technology, the present invention provides a bogie with compact structure and reasonable layout, which solves the problems of automatic centering and self-guiding of the locomotive, so that the bogie can operate on straight lines and curves It has good lateral comfort and anti-snake ability in driving, which makes up for the vacancy of independent research and development and preparation of bogies in my country.
