Problems solved by technology

[0003] Studies have shown that the hub motor provides low resistance torque at high speeds, and the energy recovery effect is poor. At low speeds, the braking energy recovery efficiency of the hub motor is high, and the braking torque provided is stable.
On the contrary, at high speed

Abstract

Provided is a vehicle hydraulic and hub motor combined braking energy recycling system. A storage battery is connected with hub motors installed on front wheels. The hub motors are connected with an input shaft on a vehicle body through a suspension; a dynamic coupler is connected with a driving axle through a first transmission shaft. The dynamic coupler is connected with a secondary element pump/motor through a second transmission shaft. The second transmission shaft is provided with an electromagnetic clutch; the secondary element pump/motor is connected with a hydraulic oil tank through a pipeline; an energy storage device is connected with the secondary element pump/motor through a three-position four-way directional control valve, and the energy storage device and the three-position four-way directional control valve as well as the secondary element pump/motor and the three-position four-way directional control valve are both connected through hydraulic pipes; and a secondary element pump/motor variable pump is installed on the hydraulic oil tank through the hydraulic pipes.

Description

technical field [0001] The invention relates to a vehicle hydraulic pressure and hub motor compound braking energy recovery system. Background technique [0002] In recent years, the national demand for automobiles has been increasing, and the number of automobiles in my country has continued to increase. The resulting energy crisis and environmental protection problems have also become increasingly severe. New energy vehicles emerged as the times require, and pure electric vehicles have become a hot research topic. The braking energy recovery system can effectively increase the mileage of electric vehicles and improve the power of electric vehicles for electric vehicles that brake frequently in urban roads. A large number of researches have been carried out on braking energy recovery technology abroad, and remarkable results have been obtained. Current research mainly focuses on in-wheel motor braking energy recovery and hydraulic braking energy recovery. [0003] The re...
