Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, to the technical side in this utility model embodiment Case is clearly and completely described, it is clear that described embodiment is only that this utility model part is real Execute example rather than whole embodiments.Based on the embodiment in this utility model, ordinary skill people The every other embodiment that member is obtained under not making creative work premise broadly falls into this utility model The scope of protection.
Referring to Fig. 1 and Fig. 2, this utility model provides a kind of power-driven system 100, and this power drives Dynamic system 100 includes: the first precursor motor 1 and the second precursor motor 2, the first precursor motor 1 and second Precursor motor 2 connects one to one with two front-wheels.In the present embodiment, the first precursor motor 1 and second Precursor motor 2 is wheel hub motor, is directly installed in corresponding front-wheel wheel rim.Use this kind of mode so that Not having intermediate mechanical drive mechanism between two front-wheels, the independence that therefore can realize two front-wheels drives control, Control mode is more flexible, and uses wheel hub motor direct drive of wheel, and response is faster, in hgher efficiency.
Rear-guard motor 3, rear-guard motor 3 is taken turns with first round side reducer 5 and second by a differential mechanism 4 Side reducer 6 connects respectively, and first round side reducer 5 and the second hub reduction gear 6 and two trailing wheels are one by one Corresponding connection.Specifically, in the present embodiment, rear-guard motor 3 is arranged on chassis of vehicle body, is joined by axle Device 12 is connected with differential mechanism 4, differential mechanism 4 again by jack shaft 13 respectively with first round side reducer 5 And second hub reduction gear 6 be connected.First round side reducer 5 and the second hub reduction gear 6 respectively with accordingly The trailing wheel wheel rim 14 of trailing wheel is connected.Rear-guard motor 3 is arranged on chassis of vehicle body, does not increase the non-of suspension Spring carried mass, can promote vehicle performance further.
The first order reducing gear that the power of rear-guard motor 3 output consists of differential mechanism 4, and the first round After the deceleration of the second level reducing gear of side reducer 5 and the second hub reduction gear 6 composition, can significantly carry High power output moment of torsion, thus the climbing of car load, the demand of the high pulling torque such as cross-country can be met.Wherein differential mechanism 4, first round side reducer 5 and the second hub reduction gear 6, is planetary gear or eccentric gear composition No-clutch form, so can be with free of losses energy regenerating.Jack shaft 13 also have transmission moment of torsion and Absorb first round side reducer 5 and the second hub reduction gear 6 function of beating relative with car body.
Offroad vehicle has when running at a low speed the demand needing high pulling torque output power to get rid of poverty, and this practicality is new First precursor motor the 1, second precursor motor 2 used in the power-driven system 100 of type and rear-guard electricity The machine 3 power regulating and controlling exportable low-speed big by power electronic controller, thus can fully meet more The requirement of wild automobile, and by power electronic controller, can accurately regulate each moment of torsion driving motor output, So that the control to moment of torsion is the most accurate, and then improve vehicle performance further.
Supply module 7 and high-tension distribution box 8, supply module 7 electrically connects with high-tension distribution box 8, high pressure Distribution box 8 is electrically connected with first precursor motor the 1, second precursor motor 2 and rear-guard motor 3.Tool Body ground, in the present embodiment, supply module 7 is high voltage power set of cells, by high voltage power set of cells, Be capable of pure power drive mode, can according to user need select battery capacity.
Additionally, power-driven system 100 of the present utility model also includes: electromotor 9 and electromotor 10, Electromotor 9 is connected with electromotor 10, and electromotor 10 is by AC/DC modular converter 11 and a high voltage power distribution Case 8 electrically connects.Electromotor 9 can drive electromotor 10 to operate, thus produces electric power, it is provided that to high pressure Distribution box 8 uses.Therefore by electromotor 9 and electromotor 10, the course continuation mileage of vehicle can be improved, Realize increasing journey drive pattern.
Power-driven system 100 of the present utility model, can pass through entire car controller, believes according to accelerator pedal Number and current vehicle speed signal, control each drive motor, it is achieved acceleration and deceleration.Can also according to current vehicle speed, Battery electric quantities etc. judge whether to start pure power mode.I.e. when high voltage power battery power abundance, The high voltage power set of cells that can be used alone realizes pure electric drive, when high voltage power battery power deficiency, then Starting electromotor 9 drives electromotor 10 to generate electricity so that electromotor 10 is powered with high voltage power set of cells simultaneously.
Such as, vehicle is when urban road travels, if now high voltage power battery power is sufficient, then and can be single Solely use high voltage power set of cells to realize pure electric drive, 4 wheel drive or 2 wheel drive can be realized.And at high pressure Power battery pack electricity is low or can start electromotor 9 when cross-country road conditions and works, electromotor 9 under this kind of pattern Simply drive electromotor 10 work generating, best effective can be maintained at by vehicle control unit controls electromotor 9 Rate operation interval, thus the fuel economy of electromotor 9 is greatly improved, and first round side reducer 5 and The application of the second hub reduction gear 6, can make rear-guard motor 3 in very large range be operated in efficient district, thus Realize energy and use maximization.
This utility model also provides for a kind of automobile, and this automobile includes above-mentioned power-driven system 100.
Power-driven system of the present utility model uses motor to export as power, can meet the little moment of torsion of low speed Traveling demand;After rear-guard motor is by differential mechanism and hub reduction gear double reduction, power can be greatly improved defeated Go out moment of torsion, thus meet car load climbing, cross-country demand, and power consumption is relatively low.And the first precursor motor and Two precursor motors all use wheel hub motor, are directly driven front-wheel, can meet higher speed demand, And owing to not having mechanical link between two front-wheels, the independence that therefore can realize two front-wheels drives control, Control mode is more flexible.Additionally, engine driven generators generating can be started when supply module electricity is low, Thus drive motor to provide electric power for each.
