Description
Technical field:
The present invention relates to a kind of change-speed box for stroke lengthening hybrid power automobile, for carrying extended-range (Range Extender, RE) hybrid vehicle, belonging to hybrid electric vehicle power art drive systems field.
Background technology:
Along with the progress of electric vehicle engineering, especially battery technology progress, and Abgasgesetz is increasingly strict, among the people and government department grows with each passing day to the business-like expectation of electronlmobil.But the high complexity of strong hybrid electric and high cost, and the short continual mileage of pure electric automobile and high cost are the business-like obstacle of electronlmobil all the time.In order to overcome above-mentioned obstacle, accelerate electronlmobil commercialization process, simultaneously improve car load fuel consumption and emission to greatest extent, a kind of for satisfied most of user's user demand novel electric vehicle---stroke lengthening hybrid power automobile enters the visual field of people.
Stroke lengthening hybrid power automobile for target market refinement more, its development idea is, based on the investigation of private car use habit, statistics, analysis, for the present situation of the every daily car kilometer of most people lower than certain numerical value, travel with pure electronic (EV) pattern in design given travel mileage, for the service condition exceeding pure motorized designs mileage once in a while, then engine power is adopted to drive vehicle to travel, with the operating needs of satisfied great majority or most user.
The advantage of RE car is, structure is general simpler than strong mix-configuration automobile in parallel with control, and fuel-economizing is more remarkable with discharge improvement.
Current, modal RE configuration is plug-in serial configured (Plug-in SeriesHybrid Electric Vehicle, PSHEV) hybrid vehicle, this kind of configuration is on the hybrid vehicle of serial configured, repacking great-capacity power battery, car load adopts electric quantity consumption (Charge Deplete, CD) control policy, to the control thought reaching first pure motor driving, rear series connection travels.But this kind of configuration needs two electric systems, and one of them uses as electrical generator, and cost and arrangement are all the huge obstacles of powertrain platform and car load commercialization.
Summary of the invention:
The object of the present invention is to provide a kind of change-speed box for stroke lengthening hybrid power automobile, is be divided into two by an axle of traditional saloon car transmission, therefore claims " dichotomic type one axle " change-speed box; For the hybrid vehicle of single motor RE configuration, adopt selector device manually or automatically all can realize powershift.Compared with plug-in serial configured, reduce the technical risk of system cost and master layout.
Technical scheme of the present invention is achieved in that the change-speed box for stroke lengthening hybrid power automobile, it is characterized in that: by left input one axle, left input one axle one grade of gear, left input one axle second speed gear, right input one axle, right input one axle one grade of gear, right input one axle second speed gear, right input one axle reverse gearwheel, two axles, left input two axle one grade of gear, left input two axle second speed gear, right input two axle one grade of gear, the composition such as right input two axle second speed gear, right input idle reverse gear, main reduction gear, diff, shifting operation mechanism; Motor is connected with change-speed box by left input one axle, and driving engine is connected with change-speed box by power-transfer clutch, right input one axle; The power of motor passes to driving wheel through left input one axle, two axles, main reduction gear, diff, transmission shaft; The power of driving engine passes to driving wheel through power-transfer clutch, right input one axle, two axles, main reduction gear, diff, transmission shaft.
It is implemented as follows:
Pure electronic (EV) pattern travels
When on-vehicle battery group state of charge (State of Charge, SOC) is not too low, battery pack be in can mode of operation time, car load can travel on EV pattern.Now engine system is closed, and right input one axle does not engage with two axles (being in neutral state).
When vehicle travel initiation or the speed of a motor vehicle lower time, power is through left input one axle one grade of gear and left input two axle one grade of gear transmission, and machine operation is in forward electric model.When the speed of a motor vehicle is higher, power transmits through left input one axle second speed gear and left input two axle second speed gear, and machine operation is in forward electric model.When car retardation or braking, no matter which grade gear above-mentioned combines, if battery pack also underfill, then motor all works in forward power generation mode; If battery pack is full of, then motor is not electronic does not also generate electricity, and is in rotary-die type.
When vehicle backing, power is through left input one axle one grade of gear and left input two axle one grade of gear transmission, and machine operation is in reverse electric model.When vehicle backing is braked, if battery pack also underfill, then machine operation is in reverse power generation pattern; If battery pack is full of, then motor is not electronic does not also generate electricity, and is in rotary-die type.
Engine drive mode travels
When the car load front travelled distance that again charges is longer, cause that battery pack SOC is too low, battery pack be in can not mode of operation time, car load travels on engine drive mode.Now electric system is closed, and left input one axle does not engage with two axles (being in neutral state).
When vehicle travel initiation or the speed of a motor vehicle lower time, engine power is through right input one axle one grade of gear and right input two axle one grade of gear transmission, and driving engine drives separately vehicle to advance.When the speed of a motor vehicle is higher, power transmits through right input one axle second speed gear and right input two axle second speed gear, and change-speed box changes to second gear, and motor-powered vehicle travels.When vehicle needs to slow down or brake, driving engine is counter to be dragged or motor vehicle braking system work, and car retardation is stopped.
When vehicle backing, right input one axle reverse gearwheel engages with idle reverse gear, and engine drive car load completes reverse travel operation.
Good effect of the present invention is the input by motor and driving engine, is integrated on a change-speed box, achieves the design philosophy of single motor stroke lengthening hybrid power automobile, reduces integral vehicle cost, also reduce the technical risk of car load calculation for layout.
