Framework for steering and bogie

Abstract

The invention relates to a framework for a steering system and a bogie with the framework. The framework comprises two side beams which extend in parallel with each other; and two cross beams which are perpendicular to the side beams. The middles of the side beams are connected with the side beams, the lower sides of the side beams are provided with first installation assemblies, the middles of the side beams are provided with second installation assemblies, and the ends of the side beams are provided with end assemblies; and the cross beams further include third mounting assemblies in the outer sides facing away from each other and fourth mounting assemblies in the lower sides. The bogie includes the framework, an axle box, a primary suspension device, a secondary suspension device, a driving transmission device, a wheel pair and a brake device, wherein the axle box and primary suspension device is arranged on a side beam of a framework; the secondary suspension device is arranged in the middle of a side beam of the framework; the wheel pair is arranged between the side beams of the framework; the driving transmission device is arranged between the wheel pair and a cross beam of the framework; and the braking device is arranged at the end part of the side beam of the framework. According to the invention, the problem of limited space is solved, the vehicle operation performance is improved, and the cable terminal is prevented from being broken.

Description

technical field [0001] The invention relates to the field of urban rail transit, in particular to a steering system of a rail vehicle, in particular to a steering frame and a bogie. Background technique [0002] At present, the standard configuration of the primary spring and braking method of the bogie of the domestic standard-gauge A-type subway vehicle is as follows: the primary spring of the A-type car with a speed of 80km / h adopts a conical metal rubber spring, and the braking method is a tread braking method; The 120km / h Type A car uses round steel springs as the primary spring, and the braking method is wheel disc braking. [0003] For the 80km / h A-type car, the advantage of using conical metal rubber springs for the primary springs is that it is easy to install and maintain, has its own damping characteristics, and reduces the configuration of primary shock absorbers, so it is very popular with subway companies. However, due to the limitation of the installation siz...

AI Technical Summary

Problems solved by technology

[0006] The method of installing the brake unit on the bogie end beam is limited by the installation space of the vehicle underframe traction beam. The end beam cannot be installed and arranged at the end of the bogie at the coupler position. The frame end beam will interfere, which will affect driving safety

[0007] Therefore, it is necessary to propose an improved bogie, so as to effectively solve the problems existing in the above-mentioned prior art due to the arrangement of the wheel brake unit at the end of the bogie, which interferes with the traction beam of the car body chassis under some working conditions, and the shaft end There is no place to fix the equipment cables on the bogie and they are directly mounted on the vehicle, resulting in broken terminals and limited space in traditional installation methods.
