Description
Technical field
The present invention relates to electric vehicle manufacturing technology field, especially a kind ofly be applicable to the electronlmobil that family and city low speed are ridden instead of walk.
Background technology
Along with the fast-developing of world economy with to the attention of environmental consciousness, the popularity rate of automobile is more and more higher, and simultaneously motor vehicle exhaust emission being required also more and more higher, energy-conservation, safe, free of contamination ideal " zero-emission " pure electric automobile is the development tendency in future.At present on the market electronlmobil mostly adopt the type of drive that is connected with rear driving axle by transmission shaft by DC machine, propons is Transmission Bridge.In use there is following deficiency in this electronlmobil: because this electronlmobil only has single bridge propulsive effort of rear driving axle, bad adaptability to road, on sliding wet bad road surface or when bend travels, skidding or breakking away easily appears in wheel, vehicle can't be left voluntarily, cause travelling dangerous, turn to dumb.
Summary of the invention
It is independent suspension that the technical problem to be solved in the present invention provides a kind of wheel, front-wheel, the drivable electronlmobil of trailing wheel, this electric automobile during traveling safely, turn to flexibly, can solve existing electronlmobil to the problem of the bad adaptability of road.
The technical scheme that technical solution problem of the present invention adopts is: this electronlmobil comprises the vehicle frame that front-wheel and trailing wheel are housed and is located at car load control setup on the described vehicle frame, it is characterized in that: the front end of described vehicle frame is equipped with three described front-wheels by three front-end equipments respectively, have at least two described front-wheels to be electrically connected with respectively front drive unit, the before driving motor that has electrokinetic cell before each described front drive unit and be electrically connected with described electrokinetic cell by forerunner's controller; Three described front-end equipments are by pull bar and car load control setup mechanical connection;
Three trailing wheels are equipped with by a plurality of rear linkages respectively in the rear end of described vehicle frame, have at least two described trailing wheels to be electrically connected with respectively rear drive unit, the rear drive motor that each described rear drive unit has electrokinetic cell and is electrically connected with described electrokinetic cell by the rear-guard controller; Described forerunner's controller and described rear-guard controller all are electrically connected with the car load control setup;
The front rake a of described front-end equipment and described vehicle frame is 75 degree～78 degree, and the casterangle b of described rear linkage and described vehicle frame is 80 degree～82 degree; Described front rake a be described front-end equipment axis towards and the place ahead of the baseplane of described vehicle frame towards between angle, the axis that described casterangle b is described rear linkage towards and the rear of the baseplane of described vehicle frame towards between angle.
In the technical scheme of above-mentioned electronlmobil, technical scheme can also be more specifically: described front-end equipment has the front fork that is located at described vehicle frame front end, and the both sides of described front fork are equipped with bumper, and described bumper is connected with described front-wheel by front axle.
Further, described rear linkage has the bumper that is located at described vehicle frame rear end, and described bumper is connected with described trailing wheel by rear axle; The back vent that supports described trailing wheel is housed between described trailing wheel and described vehicle frame.
Further, described electrokinetic cell and described electrokinetic cell are lead-acid batteries, and each described battery pack all is connected with a charger that is used for the access civil power.
The side that the operator's compartment of electronlmobil is faced is the place ahead.
Owing to having adopted technique scheme, the present invention compared with prior art has following beneficial effect:
1, because electronlmobil all is equipped with three front-wheels and three trailing wheels, two front-wheels and two trailing wheels of being contained in the electronlmobil both sides are the drive wheel that is connected with respectively drive motor, each drive wheel can carry out stepless time adjustment, middle front-wheel and middle trailing wheel are motorless secondary row travelling wheel, can stablize vehicle body; Wheel in the middle of when travelling like this or turning can play the effect of balance, make electric automobile during traveling safer, turn to more flexible, can carry out 360 degree racings and not turning on one's side, safety is stronger, if six take turns in any one wheel be out of order and do not affect normally travelling of electronlmobil.Act as and can stablize vehicle body, can prevent again because certain or a plurality of wheel when breaking down, vehicle is unlikely to cast anchor or the accident such as rollover.
2, because the wheel of electronlmobil is independent suspension, and respectively forward and backward suspension gear is provided with front rake a and casterangle b, can improve like this ability of wheel across obstacle, each wheel all can be beated in the larger context and do not affect the transmission of power, strong adaptability, stationarity to road are good, therefore, no matter run into which kind of road conditions, each wheel is can both ground connection firm and drive Vehicle Driving Cycle.
3, simple in structure, installation and maintenance are convenient, can effectively reduce the weight of electric automobile chassis, thereby reduce the weight of electric automobile whole, reduce the resistance in the electric automobile during traveling process, reduce energy consumption, 180 kilometers of 8 hours wheeleds of all lead-acid batteries chargings on the electronlmobil.
