a braking system

Abstract

The invention discloses a brake system. The brake system comprises a motor shaft, a hydraulic clamp and a brake oil cylinder. The hydraulic clamp is connected with the motor shaft. The brake oil cylinder comprises an energy storage cylinder body, a disc spring, a thrust shaft, a hydraulic cylinder body, a lead screw and a common piston, wherein the disc spring is arranged in the energy storage cylinder body; the thrust shaft is arranged on the inner side of the disc spring and can be driven by the disc spring to move; the hydraulic cylinder body is connected with the energy storage cylinder body, and an inner cavity of the hydraulic cylinder body communicates with an inner cavity of the energy storage cylinder body; the lead screw is connected with the thrust shaft, penetrates through thehydraulic cylinder body and can stretch out of the hydraulic cylinder body to apply force to the hydraulic clamp; and the common piston is located in the inner cavity of the hydraulic cylinder boy andarranged on the lead screw in a sleeving mode. According to the brake system, after brake force is applied to the motor shaft, large brake force can be provided for a vehicle through gear transmission ratio amplification, and the requirement for large speed reduction of the vehicle is met; and in addition, large brake force does not need to be provided for the hydraulic clamp, and brake force canbe provided by the disc spring with a small size, so that the size of the brake oil cylinder is reduced, and the problem of difficult assembling is solved.

Description

technical field [0001] The invention relates to the technical field of urban rail transit, in particular to a braking system suitable for vehicles. Background technique [0002] Urban rail transit vehicles such as trams and subways need to carry a large passenger flow, so they need to have a large passenger space. A design method in the prior art is to set the floor of the vehicle lower. for more passenger space. [0003] As the passenger space increases, the installation space of the braking system of the vehicle decreases accordingly. The existing braking system mainly includes a motor shaft, a gear transmission mechanism, a hydraulic clamp, a brake cylinder, a shaft disc and a wheel disc, etc. Since the vehicle runs on urban roads with complex road conditions, the vehicle needs to have a greater deceleration requirement, and the brake cylinder must be able to output a greater braking force, so that the hydraulic clamp can fully clamp the axle disc and the wheel disc to ...
