A second motor operates when a vehicle normally starts and travels, so that the daily operating requirement of a vehicle can be met; the first motor requires high power when the vehicle travels outdoors, a first clutch is switched off, a second clutch is engaged, and the battery pack provides a voltage and a current and operates together with the motor, so that the real-time four-wheel drive pattern is realized; and when the electric quantity of the battery pack is not enough, the first clutch is engaged, the second clutch is switched off, and the first motor is driven to reversely rotate by the engine so as to be taken as a generator and used for charging the battery pack.
Description
Technical field
The present invention relates to a kind of in good time four wheel drive pattern of later-model hybrid power, be specifically related to the actuating device of hybrid power vehicle under different operating modes, automobile drives the field.
Background technology
Automobile is the rich and influential family of energy resource consumption and environmental pollution; Under the situation of energy shock that is on the rise and environmental crisis; Energy-conservation and environmental protection has more and more become two hang-ups of current society; Pure electric automobile has become the inexorable trend of auto trade development, but that is that all right is ripe for the technical merit of the battery of present stage, so the hybrid power vehicle has become the transitional product that an automobile enterprise falls over each other to develop.
The electrical motor of the hybrid power vehicle of comparative maturity is still as accessory power system in the market, and main power system or driving engine belong to Weak hybrid power.
Summary of the invention
The technical matters that the present invention will solve is to overcome existing defective, and a kind of in good time four wheel drive pattern of later-model hybrid power is provided.It can satisfy the pure motorized motions pattern of in good time 4 wheel driven under pure electrically operated back-wheel drive pattern, outdoor operating mode under the operating mode of city; In this process if the battery deficiency can't in time reach charging zone when charging again; Two-cycle engine can drive first electrical motor counter-rotating generating, and can adopt the back-wheel drive pattern this moment.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
A kind of in good time four wheel drive pattern of later-model hybrid power is characterized in that:
Comprise wheel, second electrical motor, rear-end gear reduction, rear axle shaft, two-cycle engine, first clutch, first electrical motor, second clutch, change-speed box, front axle propeller shaft, battery pack, switch box, power supervisor, charger, fuel tank,
Said second electrical motor is connected with rear-end gear reduction, and rear-end gear reduction is connected with rear axle shaft, and rear axle shaft is connected with rear wheel,
The said two-cycle engine and first electrical motor break off through first clutch or engage; First electrical motor engages two-cycle engine through first clutch under the situation of battery deficiency, being driven as electrical generator by two-cycle engine is batteries charging;
Disconnection or the joint of said first electrical motor through second clutch is connected with change-speed box or breaks off; First electrical motor vehicle power not enough situation under through the second clutch joined speed variator; Through change-speed box and front axle propeller shaft drive wheels; Work with second electrical motor, get into the four wheel drive pattern;
Said battery pack is that first electrical motor and second electrical motor provide operating voltage and electric current through switch box, and stores the electric weight that two-cycle engine drives first electrical motor counter-rotating generating generation through switch box.
The development level of battery makes the ability of storage electric weight of battery not have to reach the continuation of the journey mileage requirement of satisfying pure electric automobile in view of present stage, and it is batteries charging in economic working condition work that the driving engine that the present invention sets up one two stroke makes it.Both increase the continuation of the journey mileage ability of battery, also reached the purpose of energy-conserving and environment-protective.
Specifically; The invention provides a kind of in good time four wheel drive pattern of later-model hybrid power; It can satisfy the pure motorized motions pattern of in good time 4 wheel driven under pure electrically operated back-wheel drive pattern, outdoor operating mode under the operating mode of city; If the battery deficiency can't in time reach again when charging is electric charges, two-cycle engine can drive first electrical motor counter-rotating generating in this process, and can adopt the back-wheel drive pattern this moment.
Second electrical motor is worked when the normal starting of vehicle is gone, and satisfies the daily operating needs of vehicle
First electrical motor goes when needing big power at vehicle out of doors, and first clutch breaks off, and second clutch engages, and provides voltage and current and electrical motor to work together by battery pack, realizes the pattern of in good time 4 wheel driven driving; When battery was not enough, first clutch engaged, and second clutch breaks off, and first electrical motor is batteries charging by the engine drive counter-rotating as electrical generator.
Two direct motor drive that the main forward back of going of vehicle is arranged; Driving engine can be worked under a both economical operating mode just as an auxiliary generating plant always, and power directly is not provided; The tail gas that produces can be fewer, also can be than higher to the service efficiency of fuel oil.Compare with the drive pattern of present hybrid power, the power resources of this drive pattern are the front and back electrical motors of arranging, driving engine as auxiliary generating set, is a kind of strong hybrid electric pattern only.
