Description
The utility model relates to the electronlmobil propelling unit of being travelled by drive wheel before and after the alternating-current motor/AC motor driving.
Be in the automobile of drive source with the combustion engine, using gasoline or light oil to make the automobile of fuel, deal with at aspects such as the preservation of fuel, transportations than being easier to, but it is having aerial contamination and noise pollution etc. to cause the destruction problem of environment conversely; In the automobile that liquefied natural gas is acted as a fuel, aerial contamination has reduced, but the danger of comparing the fuel blast with gasoline increased, and the problem of the inconvenience handled is arranged.In addition, any fuel allowable exploitation is limited, any all problems that nature exhaustion etc. is all arranged.
With respect to this, electrification drives the electronlmobil travel, needn't worry about air pollution at all, and storage source is also guaranteed in the peace and quiet of travelling easily.
But, variety of issue is also arranged in such electronlmobil.Promptly utilizing DC motor to carry out under the situation of driving of drive wheel,, making current loss become big, can not travel for a long time owing to come control rate by changing current value; On the other hand, strengthen accumulator capacity for wanting to travel for a long time, it is heavy that storage battery becomes, and the electric automobile during traveling performance reduces, and, because the increasing of storage battery is difficult to guarantee the space is set, interior space is narrowed down.
In addition, the invalid stream of the charging current of storage battery changes in travel, and for using frugally, also must improve the effective rate of utilization of storage battery.
The utility model promptly because the problems referred to above that prior art exists make, its purpose be to provide with alternating-current motor/AC motor drive drive wheel, can be in travelling to battery charge, seek effectively to utilize the electronlmobil propelling unit of storage source.
In order to solve above-mentioned problem, it is constructed as follows electronlmobil propelling unit of the present utility model: the axle drive shaft of the DC motor 2 that is electrically connected with storage battery 1 is connected with the S. A. of alternating current generator 3, power at the load terminal of the supply electro-motive force of this alternating current generator 3 and to connect the AC side loop of rectifier 4 and alternating-current motor/AC motor 5, this rectifier 4 is connected with storage battery, when driving alternating-current motor/AC motor 5 with this electro-motive force, and an electro-motive force part is passed through rectifier 4 charge, drive wheel before and after the driving power of alternating-current motor/AC motor 5 passes to by change gear set 6 to storage battery 1.
Electronlmobil propelling unit of the present utility model preferably disposes four alternating-current motor/AC motors 5 corresponding to each drive wheel of front and back, and can drive respectively separately; Be more preferably, in this case, drive an alternating-current motor/AC motor 5 during starting; The starting back drives one or more alternating-current motor/AC motor 5 according to condition of road surface and travels.
Fig. 1 is the skeleton diagram of the formation of expression the utility model electronlmobil propelling unit one embodiment.
Borrow description of drawings the utility model one most preferred embodiment.
The formation of one of the utility model propelling unit example represented in Fig. 1 summary, symbol 1 is that a plurality of polyphones of single battery that will have the capacitance of storage of 12 volts or 24 volts get up to be formed on the storage battery that can obtain 100 volts of vdcs between mouth among the figure, by making the action of not shown charger, and the electric current that the power supply machine outside car of can charging is supplied with.
The 2nd, DC motor, it is by the current drives rotation of supplying with from storage battery 1 by control panel 7 described later, and its axle drive shaft is connected with the turning cylinder of alternating current generator 3; The 3rd, with that rotate, that generate electricity the synchronously alternating current generator of axle drive shaft of DC motor 2; The 4th, the rectifier that is electrically connected with the load terminal of alternating current generator 3, being transformed to the straight-though induced electric motive force with this rectifier can be to above-mentioned storage battery 1 charging.
The 5th, but be electrically connected with the load terminal of above-mentioned alternating current generator 3 and individual drive before and after drive wheel and be located at alternating-current motor/AC motor on each drive wheel; The 6th, the propulsive effort of alternating-current motor/AC motor 5 is delivered to the change gear set of wheel, it is designed to: by one of each wheel or each individually the gear that is connected of proper transformation alternating current generator 5 can obtain desired drive torque.Also can drive all drive wheels by an alternating-current motor/AC motor 5.
The 7th, the control circuit of built-in each machine, with automatic or manual operation each machine is carried out as the control panel of controlling.Though not shown, in fact the various operation signals of running operation portions such as the power switch of electronlmobil and handle, accelerator, drg are also imported control panel 7; Corresponding to these signal design above-mentioned each machine is carried out automatic start control.
Each machine is such as the use that the alternating-current motor/AC motor 5 that connects the rectifier 4 of alternating current generator 3,20KW of DC motor 2, the 100KW of storage battery 1, the 15KW of 9 12 volts single battery formation and 25 horsepowers can be combined.
Propelling unit of the present utility model is made of above-mentioned each member, the power switch of closed electric power input electronlmobil, drive DC motor 2 by control panel 7, and the load terminal of the alternating current generator 3 that is connected of DC motor 2 between produce AC electromotive force, drive alternating-current motor/AC motor 5 with this induced electric motive force, drive drive wheel by change gear set 6.
In this case, when being output as 100KW such as the electric power of alternating current generator 3, the 15KW in the available output to storage battery 1 charging, successively drives four alternating-current motor/AC motors 5 with remaining 85KW by rectifier 4.That is, Yi Bian drive drive wheel, Yi Bian, synthetically protect storage battery 1 thus simultaneously to storage battery 1 supply capability side by side; Particularly when parking or downhill braking, can realize that the rotational energy that absorbs drive wheel becomes to storage battery 1 electrically-charged regenerative brake, can improve the degree of utilization of storage source.
In addition,,, make exciting current become big, can obtain starting the moment of necessary enough sizes because the electric power with 85KW drives an alternating-current motor/AC motor 5 during starting if establish four alternating-current motor/AC motors 5; Then, owing to drive other alternating-current motor/AC motors 5 successively in travelling, can suppress the generation of excess current on one side, but smooth starting is on one side travelled.Moreover, by being provided with four alternating-current motor/AC motors 5 that can drive independently, when advance in the level land can with two, can be with four alternating-current motor/AC motors 5 when advance in the ramp.Can obtain comfortable rideability corresponding to the road surface situation.
Propelling unit of the present utility model, owing to be to drive drive wheel with alternating-current motor/AC motor, the excess current in the time of can not producing by the starting under the DC motor driving situation can make the storage battery of equal capacity use the longer time.
As use electronlmobil propelling unit of the present utility model, and when can effectively utilizing storage battery, also can realize comfortable walking performance corresponding to the road surface situation, extremely practical.
