Braking energy storage device for pure electric bus and working method thereof

Abstract

The invention discloses a braking energy storage device for a pure electric bus and a working method thereof. The braking energy storage device for the pure electric bus comprises an air compressor, acopper coil tube, a condenser, a dryer, a four loop, a foot operated brake valve, a hand brake valve, a regenerated air reservoir, a front braking air reservoir, an auxiliary air reservoir, a hand braking air reservoir, a rear braking air reservoir and a controller; the air compressor, the copper coil tube, the condenser, the dryer and the regenerated air reservoir are connected with each other in sequence through copper pipes and mutually form a main air source pipeline; the four loop, the front braking air reservoir, the auxiliary air reservoir, the hand braking air reservoir, the rear braking air reservoir, the foot operated brake valve, the hand brake valve and the controller are connected with each other through nylon pipes to form a braking energy supply assembly; and according to the working method, condensation and sewage draining of the pipeline are realized in an electric controlled and temperature controlled manner; and the controller controls the air compressor to start and stop. According to the braking energy storage device for the pure electric bus and the working method thereof, the working efficiency of a braking system is enhanced on the basis of guaranteeing thesafety and reliability of the whole braking system, and the energy utilization efficiency is enhanced.

Description

technical field [0001] The invention relates to the technical field of pure electric passenger car braking, in particular to a pure electric passenger car braking energy storage device and a working method thereof. Background technique [0002] Compared with the configuration of traditional buses, pure electric buses use battery packs as the power source. The load of the whole vehicle is heavier, and the requirements for braking performance of the whole vehicle are higher. A reliable energy storage device is an important guarantee. However, the use of electric air compressors to replace traditional air pumps requires a complete set of technical solutions based on their technical characteristics and the energy-saving features of new energy vehicles. The vehicle's multi-configuration air suspension can improve the comfort of the vehicle, and its power source also comes from the air compression device. With the gradual popularization and application of pure electric buses, the...

AI Technical Summary

Problems solved by technology

[0003] The existing pure electric passenger car brake energy storage device has poor removal effect on water and oil in the compressed air, and lacks heating function, which leads to an increase in the invalid working time of the air compressor, which not only reduces the service life of the air compressor, but also reduced energy efficiency
