An installation structure of a wheel disc brake and a bogie using the installation structure

Abstract

The invention relates to an installation structure of a wheel disc brake and a bogie employing the installation structure. The installation structure comprises wheel disc brakes, a frame, and a wheel set connected with the frame, the frame comprises side beams at two sides and a crossbeam for fixing the side beams at the two sides, two sides of wheels of the wheel set are provided with brake discs, the wheel disc brakes are provided with a front suspension device and a rear suspension device, the side beams are provided with installing seats, and the front suspension device and the rear suspension device are suspended and fixed on the installing seats. According to the installation structure, larger brake heat can be born, the installation structure is fixed on the side beams in a hinged suspension manner, the movement of the brakes is not influenced, the bearing intensity of the crossbeam is reduced, the internal structure of the bogie is more reasonable, the structure is compact, and the installation of the brakes is facilitated; besides, a rear installing seat employs a hollow round steel tube so that the weight of the rear installing seat is reduced, and the stress of vertical plates of the side beams can be reduced.

Description

technical field [0001] The invention relates to an installation structure, in particular to an installation structure of a disc brake and a bogie using the installation structure. Background technique [0002] The bogie of a subway vehicle is an important part of the entire vehicle, and its performance directly affects the overall safety, stability, and running speed of the vehicle. Metro vehicles are mainly divided into three types: Type A, Type B and Type C. The main difference between them is the width of the car body. Among them, the width of the car body of the type A car is the largest, the maximum passenger capacity, and the corresponding axle load of the bogie is also The larger, but basically below 16t. The A-type subway vehicle in the prior art has a designed axle load of only 16t and a limited passenger capacity, which can no longer meet the demand for subway passenger capacity during urban traffic peaks, and cannot well relieve urban transportation pressure. ...

AI Technical Summary

Problems solved by technology

The A-type subway vehicle in the prior art has a designed axle load of only 16t and a limited passenger capacity, which can no longer meet the demand for subway passenger capacity during urban traffic peaks, and cannot well relieve the pressure of urban transportation.

[0003] The braking system of the bogie is related to the braking capacity of the entire vehicle and is an important part of the entire bogie. The existing braking system is installed on the beam, which is not conducive to the layout and design of the internal equipment of the bogie when the space is tight. , and in order to improve the transport capacity, when the axle load is increased, the motor and the gearbox will have an excessive load on the beam, and the installation of the braking system on the beam is not conducive to reducing the load of the beam
