Abstract

The invention relates to the technical field of rail vehicles, in particular to a micro-rail vehicle and a braking system and method thereof. The braking system comprises a hydraulic device, a brakingdevice, a motor and a control device. The control device is used for obtaining braking distance information, weight information and speed information of the micro-rail vehicle, calculating braking force needed by the micro-rail vehicle and the rotating speed and torque, corresponding to the braking force, of the motor according to the obtained braking distance information, weight information andspeed information, and sending the rotating speed and torque information obtained through calculation to the motor. The motor is used for driving the hydraulic device according to the rotating speed and torque information; and the braking device is in fluid communication with the hydraulic device and used for generating braking force through hydraulic oil provided by the hydraulic device. The braking system can meet the requirement of the micro-rail vehicle for the braking performance and has the advantages of being simple in structure, small in size, light in weight, flexible in control and short in braking response time.

Description

technical field [0001] The present application relates to the technical field of rail vehicles, in particular to a micro-rail vehicle and its braking system and braking method. Background technique [0002] As a light, low-speed, medium-to-low volume, point-to-point, customized, fully automatic driverless new type of public transportation, micro-rail vehicles are an integral part of an integrated, multi-modal, three-dimensional public transportation system. Public transportation, rail transit and other other public transportation methods are developed in dislocation and complement each other. They are beneficial supplements and improvements to other public transportation methods, and have outstanding advantages in terms of humanization, environmental matching, construction period and cost. [0003] As the core component of the micro-rail vehicle, the braking system is the key system to ensure the safe operation and reliable stopping of the vehicle. For micro-rail vehicles, ...
