Document Type and Number:
WIPO Patent Application WO/2020/077687
Kind Code:
A1
Abstract:
A micro-rail vehicle, and a braking system and a braking method therefor. The braking system comprises a central control device (11), a control unit (12), a hydraulic device (13) and a braking device (14). The central control device (11) is used for acquiring braking distance information, weight information and speed information of a micro-rail vehicle, and calculating a braking force required by the micro-rail vehicle according to the acquired braking distance information, weight information and speed information. The control unit (12) is used for calculating the rotation speed of an electric motor (131) according to information of the braking force, and sending information of the rotation speed to the electric motor (131). The hydraulic device (13) comprises a hydraulic pump (132) and the electric motor (131) for driving the hydraulic pump (132). The braking device (14) is used for generating the braking force by means of hydraulic oil provided by the hydraulic pump (132). The braking system is applicable to the micro-rail vehicle, and has the characteristics of a simple structure, a small volume, a light weight, a high control accuracy and a short braking response time.
