Four-wheel-driving hybrid power system

Abstract

The invention discloses a four-wheel-driving hybrid power system, and aims to overcome the problems that the current four-wheel-driving hybrid electric vehicle cannot realize the optimal control of anengine and the parking electricity generation cannot be realized. The four-wheel-driving hybrid power system comprises an engine, a planetary row, a number one motor, a number two motor, a number oneclutch, a number two clutch, a number three clutch, a number four clutch, a number one brake, a number two brake, a gear I, a gear II, a gear III, a gear IV, a gear V and a gear VI. According to thefour-wheel-driving hybrid power system disclosed by the invention, the engagement / separation condition of different clutches and a brake is controlled, different modes can be realized.

Description

technical field [0001] The present invention relates to the technical field of hybrid vehicles, more precisely, the present invention particularly relates to a four-wheel drive hybrid power system. Background technique [0002] Due to the dual pressure of energy shortage and environmental pollution, governments of various countries are formulating policies to develop energy-saving and new energy vehicles. Because of the advantages of low fuel consumption, low emissions and long driving range, hybrid power has been widely recognized and has become a research hotspot for automobile companies and research institutes in various countries. Among them, the hybrid hybrid vehicle combines the advantages of series and parallel, and is the focus of research among the three. [0003] Four-wheel drive vehicles have better power and passability than two-wheel drive vehicles, while traditional four-wheel drive vehicles consume more fuel and emit more pollutants. Applying hybrid technolo...

The Chinese patent publication number is CN102381177A, an electric four-wheel drive hybrid power system and its control method, which discloses a parallel four-wheel drive hybrid power system. In this configuration, one motor drives the rear wheel, and the engine and another motor pass through the planetary The front wheels are driven by the platoon, this configuration does not allow optimal control of the engine

The Chinese patent publication number is CN204398847U, a four-wheel drive hybrid power system, which discloses a four-wheel drive hybrid power system. There are two hub motors on the two rear wheels of this configuration to realize the rear wheel drive, and the engine and another motor The front wheels are driven by a planetary gear device. In this configuration, the planetary gear ring gear is connected to the differential of the front drive axle, so that the torque of the engine is not decoupled from the road load, and the optimal control of the engine cannot be achieved. At the same time, this configuration cannot Realize the function of parking power generation
