Hybrid power bus braking system

Abstract

The invention relates to a hybrid power bus braking system. The hybrid power bus braking system comprises an engine inflating pump, an electric inflating pump, a bi-pass one-way valve, a four-circuit protection valve, a relay valve, a differential relay valve, a left front-axle air chamber, a right front-axle air chamber, a left rear-axle air chamber, a right rear-axle air chamber, a main foot braking valve, a hand braking valve, a front braking air reservoir, a rear braking air reservoir, a hand braking air reservoir, an auxiliary air reservoir, a regenerative air reservoir and a dryer. According to the technical scheme, the hybrid power bus braking system has the advantages that since two kinds of braking air sources provided by the conventional inflating pump and the electric inflating pump are designed in a full vehicle, stable full-vehicle baking performance can be guaranteed, and the requirements on energy conservation and environment protection can be met.

Description

technical field [0001] The invention relates to the technical field of passenger cars, in particular to a braking system of a hybrid electric passenger car. Background technique [0002] With the development of society and the continuous progress of the bus industry, energy conservation has increasingly become an important reference factor for bus design. The market share of new energy and hybrid buses is also increasing, and people's requirements for the braking performance of buses are getting higher and higher. Most of the brake systems of existing models use the engine with an air compressor (that is, a conventional engine air pump) to compress and supply air to provide the source of air brakes for the whole vehicle. Usually, when designing the braking system of the whole vehicle, it is necessary to provide auxiliary conditions and technical requirements: the connection between the air compressor and the dryer needs a metal pipe and keep it above 5m to prevent the rub...

AI Technical Summary

Problems solved by technology

Usually, when designing the brake system of the whole vehicle, it is necessary to provide auxiliary conditions and technical requirements: the connection between the air compressor and the dryer needs a metal pipe and keep it above 5m to prevent the rubber in the dryer from being damaged due to the high temperature of the gas. Early failure of components; especially to avoid oil leakage of the air compressor, oil leakage of the air compressor will lead to failure of the dryer or poor drying effect

The existing braking system of passenger cars cannot meet the requirements of energy saving and environmental protection, and when there is a braking failure, the whole vehicle cannot run stably
