Emergency Brake System for Light Rail Transit Vehicles

Abstract

The invention relates to an emergency braking system for a light-duty rail transit vehicle, comprising an emergency braking wheel, an emergency braking arm, a hydraulic system and an emergency braking control system. The wheel center of the emergency braking wheel is provided with a wheel shaft, and one end of the emergency braking arm is connected to the The other end of the emergency brake arm is connected to the wheel shaft; the hydraulic system is the power mechanism of the emergency brake system, which includes a hydraulic cylinder and a hydraulic pump. One end of the hydraulic cylinder is connected to the vehicle body, and the other end is connected to the vehicle through the hydraulic cylinder shaft. Between the midpoint of the emergency brake arm and the connection point between the emergency brake arm and the wheel shaft; the emergency brake control system can control the hydraulic pump to drive the hydraulic cylinder to move downward, and then drive the emergency brake wheel to move downward to the surface of the driving track through the emergency brake arm. The frictional force with the driving track makes the vehicle brake urgently. The invention shortens the braking distance of the vehicle, improves the safety performance of the vehicle, and has a simple and easy solution and strong practicability.

Description

technical field [0001] The invention relates to the field of light rail transit, in particular to an emergency braking system for light rail transit vehicles. Background technique [0002] At present, with the rapid growth of the urban population, the urban transportation system is becoming more and more complex. Light rail transportation such as trams, light rails, subways, etc. are fast, punctual, energy-saving and safe transportation methods in many cities in the world. widely used. The increase of stations, the increase of vehicle speed, and the complexity of traffic conditions all put forward higher requirements for the driving of light rail transit vehicles. For example, in many cases, emergency braking is required to deal with emergencies. However, the emergency braking system of the existing light rail transit vehicles is realized by the common braking system of the vehicle. The emergency braking speed is low, the braking distance is long, the safety is poor, the em...
