Description

Range-extended electric car novel on-vehicle generator

Technical field

The utility model belongs to a kind of portable generator of electrocar, relates in particular to the range-extended electric novel on-vehicle generator that a kind of small-sized electric car is used.

Background technique

There are all disadvantages in the current fuel engine automobile that generally uses, and statistics shows that under the road conditions that accounts for more than 80% general car has only utilized 40% of power potential, also can fall to 25% in the urban district, and even more serious is the discharging waste gas befouling environment.Since the nineties in 20th century, grow to even greater heights to the cry that improves environmental protection in countries in the world, and various electric vehicles are shown one's talent.

Because the energy density of battery and gasoline is the ratio hundreds of times mutually, reach the desired numerical value of people far away, the expert estimates also can't replace the fuel engine automobile in 10 years with interior electric vehicle, and reality forces engineers to find out a way that makes the best of both worlds, and has developed a kind of mixed power plant.Exactly motor and auxiliary power unit are combined on the automobile and do driving force, auxiliary power unit is actually a small-sized engine fuel or dynamic power unit.Image a bit says, exactly conventional engines done as far as possible for a short time, allows a part of power be born by battery-electric motor system.It is long that this mixed power plant had both been brought into play the motor continuous working period, the advantage of good dynamic property, can bring into play pollution-free, the low noise benefit of motor again, the two " is fought side by side ", learn from other's strong points to offset one's weaknesses, the thermal efficiency of automobile can improve more than 10%, and toxic emission can improve more than 30%, has produced hybrid vehicle thus.

At present, hybrid vehicle has tandem, parallel, series-parallel structural type.

Tandem power is made up of motor, generator and motor three part power assemblies, forms the power unit system of SHEV between them with the mode of series connection.Load hour drives wheel by battery driven motor, loads then to drive the generator for electricity generation drive motor by motor when big.When electric motor car place as start, quicken, during the operating mode of climbing, motor-motor unit and battery pack provide electric energy to motor jointly; When electric motor car place low speed, slide, during the operating mode of idling, then by the battery driven motor, by the Engine-Generator group to batteries charging.This tandem electric motor car finally all will come driving wheel by motor no matter under what operating mode.

The motor of parallel device and motor drive automobile in the mode of mechanical energy stack, and motor and motor adhere to two cover systems separately, can provide moment of torsion to automotive transmission independently respectively, not only can drive jointly but also can single driving on different road surfaces.Motor not only can be made motor but also can make generator and use, and is called the electric-generating unit again.Owing to there is not independent generator, motor can directly pass through the driving mechanism driving wheel, so the more approaching traditional automobile driving system of this device, obtains using more widely.

Series-parallel power claims series parallel type power again: comprised tandem and parallel characteristics.

The shortcoming of prior art is: have electric vehicle now owing to comprise motor, generator and motor three part power entities, and its complex structure, and battery has occupied a large amount of spatial position, the spatial arrangement of whole power system is the problem that is difficult to solution.

The model utility content

At the characteristics of small-sized serial type hybrid automobile spatial structure compactness, at left bent axle and each integrated generator of right bent axle of motor, the power supply of two-terminal generator output converts battery or the required power supply of main motor after treatment to.

Motor starts the back and works in a constant speed range under ECU control, and left bent axle and right bent axle are exported certain rotating speed and moment of torsion simultaneously, and pass to left end rotor and right-hand member rotor respectively; The magnetic field that the left end rotor of rotation and right-hand member rotor produce rotation respectively, thus allow the multistage coil of left end stator and right-hand member stator produce electric current respectively, promptly get left end electric current and right-hand member electric current; Left end electric current and right-hand member electric current convert out-put supply to after importing the power supply adaptor processing simultaneously---battery or the required power supply of main motor.

Because motor and generator are become one, under the situation of equal generated output, its space geometry size is littler, be convenient to the layout of small-sized electric car, and manufacture cost is lower.

The power output end of described left and right generator is connected on same the power supply adaptor.

The electric current that motor left and right sides two-terminal generator produces by the different adjusting of power supply adaptor, can be suitable for the demand of multiple vehicle.

Described rotor is the magnetic cylinder, and the stator of described left and right generator is installed in the magnetic cylinder, and described stator fixedlys connected with motor 1 housing, and this stator is connected with described power supply adaptor by wire harness.

After described left bent axle and right bent axle pass described stator respectively, fixedly connected with described rotor, the center line of described left bent axle, right bent axle, rotor and stator is on same straight line.

Owing on motor left side bent axle and right bent axle, arrange generator symmetrically, help the balance of engine crankshaft, reduce engine luggine, improve the car load travelling comfort.

Also be provided with starting electrical machinery, start reducing gear and free wheel device, the output shaft double as of described starting electrical machinery starts the input shaft of reducing gear, the output gear of this startup reducing gear is engaged with and surmounts starter receiver, this surmounts the starter receiver sky and is enclosed within on the described left bent axle, free wheel device is fixed on the described left bent axle, and the roller that surmounts of this free wheel device is connected with the described axle journal that surmounts starter receiver.

Be fixed with driving gear on the described right bent axle, this driving gear is engaged with oil pump driven gear and water pump driven gear simultaneously.

Remarkable result of the present utility model is:

1, because motor and generator are become one, under the situation of equal generated output, its space geometry size is littler, be convenient to the layout of small-sized electric car, and manufacture cost is lower;

2, owing to arrange generator symmetrically, help the balance of engine crankshaft, reduce engine luggine, improve the car load travelling comfort at the two ends, the left and right sides of engine crankshaft;

3, the electric current of motor left and right sides two-terminal generator generation by the different adjusting of power supply adaptor, can be suitable for the demand of multiple vehicle.
