Problems solved by technology

[0004] However, this braking method has the disadvantage of low conversion efficiency. Generally, regenerative braking can only regenerate about 30% of the kinetic energy, and the rest of the kinetic energy is still turned into heat; the technical content is high; the building volume is large energy storage device; and this braking method can only be limited to electric vehicles

Abstract

The invention discloses a method and a device for storing and utilizing train brake energy. Speed reducing is performed through three-lever gear transmission, gear rotation is changed into gear translation through gear rack transmission, and spring contracting energy storage and extending energy discharge are achieved by connection of a rack and a spring. A train energy-saving brake device which utilizes spring contraction to store energy during brake and utilizes spring extension to output power during travelling is provided, and is simple in structure, low in production cost, energy-saving and efficient. By the device, train brake energy storage and utilization are achieved conveniently, flexibly and reliably, and promising popularization prospect is achieved.

Description

technical field [0001] The invention relates to a train braking method and its device, in particular to a storage and utilization technology of train braking energy. Background technique [0002] With the rapid development of science and economy and the continuous improvement of people's living standards, rail transit has become an important means of transportation. Trains are massive, run fast, and require a lot of braking energy when they brake. [0003] Regenerative braking is currently a braking method that can achieve braking energy recovery. The kinetic energy generated by the useless or unnecessary or harmful inertial rotation of the electric machinery is converted into electrical energy, and fed back to the grid, and at the same time, a braking torque is generated to make the electric machinery quickly stop the useless inertial rotation. An electromechanical machine is a device with moving parts, usually rotary motion, that converts electrical energy into mechanica...
