Embodiment Construction

[0014] Such as figure 1 and figure 2 As shown, the light rail transit vehicle emergency braking system of the present invention includes an emergency braking wheel 120, an emergency braking arm 130, a hydraulic system and an emergency braking control system. The emergency brake wheel 120, the emergency brake arm 130, and the hydraulic system are all arranged at the bottom of the vehicle body, and the emergency brake control system is arranged in the vehicle cab, so that the driver of the vehicle can directly start the emergency brake control system to realize fast emergency braking when encountering an emergency.

[0015] The wheel center of emergency brake wheel 120 is provided with wheel axle 150, and the wheel of emergency brake wheel 120 is the metal wheel that comprises friction material, has larger coefficient of friction between its wheel surface and driving track 110; One end of emergency brake arm 130 passes through A rotating shaft 140 is connected to the vehicle b...

Abstract

The invention relates to an emergency braking system of a light rail transportation vehicle, comprising an emergency brake wheel, an emergency brake arm, a hydraulic system and an emergency brake control system, wherein the center of the emergency brake wheel is provided with an axle, one end of the emergency brake arm is connected to the vehicle body through a rotating shaft, the other end of the emergency brake arm is connected to the axle; the hydraulic system is the power mechanism of the emergency braking system, and comprises a hydraulic cylinder and a hydraulic pump, wherein one end of the hydraulic cylinder is connected to the vehicle body, the other end is connected between the midpoint of the emergency brake arm and the midpoint of the emergency brake arm and the axle through a hydraulic cylinder shaft; and the emergency brake control system can control the hydraulic pump to drive the hydraulic cylinder to move downwards, thus the emergency brake arm further drives the emergency brake wheel to move downwards to the surface of a vehicle rail, and frictional force is generated between the emergency brake wheel and a travelling rail to emergently brake the vehicle. The system of the invention shortens the brake distance of the vehicle, improves the safety performance of vehicle travelling, and has simple, convenient and flexible scheme and stronger 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...
