Power regeneration type braking and boosting integrated device used for locomotive

Abstract

The invention discloses a power regeneration type braking and boosting integrated device used for a locomotive. The kinetic energy of the locomotive is recycled by virtue of a gear set, and the recycled kinetic energy of the locomotive is converted into air potential energy to be stored by virtue of a double screw air compressor. When the compressed air reaches a certain pressure, a generated counter acting force inhibits the action of the double screw air compressor, and finally the locomotive brakes. When the locomotive starts, the compressed air is released and expands to do work and then drive a high pressure air engine, thus the locomotive is driven. The dead weight of the device in the invention can be controlled in a lighter range, and the braking is safe and stable when a frictiontype braking is combined; and the energy recycling efficiency is high, the application range is wide, and the device can be applied to multiple locomotives and other traffic tools.

Description

technical field [0001] The present invention relates to the field of power regeneration and energy-saving devices for locomotives, in particular to a power regenerative brake and booster integrated for a locomotive that utilizes the form of pressure potential energy of compressed air to store converted kinetic energy and can assist the locomotive to move forward when the locomotive is started. device. [0002] Background technique [0003] At present, there are related technologies that use compressed air as a power source to drive automobiles and other means of transportation, and there are also related technologies that use compressed air as an energy storage medium; at the same time, the braking method of locomotives is based on friction brakes Mainly, such a braking mode has the advantage of fast braking, but has the disadvantage of energy waste; the existing regenerative braking converts kinetic energy into electric energy, which is suitable for electrified railway tra...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to add motor power generation equipment and power storage for the locomotive through friction braking, the waste of heat dissipation energy of friction braking and the conversion of kinetic energy to electric energy in the prior art to recover the heat energy generated by friction braking. The high equipment cost and the defect of increasing the locomotive’s own weight provide a method that uses the reaction force of air compression as the braking force and stores the energy converted from the kinetic energy of the locomotive in the form of its pressure potential energy, and regenerates the energy as power when the locomotive starts.
