Abstract

A vehicle braking kinetic-energy regenerative device relates to a petrol-saving attachment for reclaiming the vehicle braking kinetic-energy, and aims to solve the problem of poor energy-saving effect in the prior vehicle braking kinetic-energy regenerative device. In the vehicle braking kinetic-energy regenerative device, a first brake and a slippage pump are respectively arranged at two ends of a first driven shaft; a second brake and a hydraulic pump motor are respectively arranged at two ends of a second driven shaft; a control oil-channel hydraulic pump is arranged at the middle part of the second driven shaft; an electrohydraulic change valve is connected with a high-pressure hydraulic accumulator; and a central control unit is respectively connected with the brakes, the second brake, the hydraulic pump motor and the electrohydraulic change valve. The vehicle braking kinetic-energy regenerative device recycles the vehicle braking kinetic-energy when the vehicle brakes, and drives the vehicle by releasing the recycled energy when the vehicle starts. The work efficiency of the energy is improved by the active stamping of the slippage pump. The vehicle braking kinetic-energy regenerative device is applicable to city buses and engineering vehicles, and can improve the kinetic performance and the braking performance of vehicles only by slightly reforming the prior vehicles.

Description

technical field [0001] The invention relates to a fuel-saving additional device for recovering braking kinetic energy of a vehicle, which can be used in various urban public transport vehicles and engineering vehicles to recover and reuse the braking kinetic energy of the vehicle, and can automatically adjust the fuel-saving device for operating conditions of the engine. Background technique [0002] As the number of vehicles increases year by year, the energy consumption and exhaust emissions of urban buses, which start and brake frequently, are becoming more and more serious, which has caused huge pressure on my country's energy security and environmental protection. Traditional automobiles use the frictional resistance generated by the mechanical braking system to achieve deceleration or parking, and the braking kinetic energy of the vehicle is converted into heat and wasted in vain. Existing vehicle braking kinetic energy recovery adopts fuel-saving booster device, altho...
