Description
Technical field
The utility model belongs to electric four-wheel vehicle field, relates to a kind ofly having the battery-driven car entirely turned to real-time 4 wheel driven function.
Background technology
Along with day by day serious atmospheric contamination and energy shock; battery-driven car obtains research and development more and more widely, and current most of battery-driven car is all the type of drive of front two-wheeled or rear two-wheeled, but; compare the automobile of 4 wheel driven, simple two-wheel drive can seem that the dynamic property of battery-driven car is not enough.Meanwhile, existing battery-driven car major part is front-wheel steering, can not adjust cornering properties in real time, because minimum turning radius is excessive, can not realize turning to of safety, cannot adapt to complex road condition in narrow space; When battery-driven car turns to when running at high speed, cornering properties can trend towards negative understeer, thus easily causes whipping.
Therefore, some scholars begin one's study can the battery-driven car of four wheel drive and four-wheel steering, such as " a kind of four motorized wheels, independent steering electric car coordination control system " notification number: CN103434506A patent of invention, this technology refer to torque and the four-wheel independent steering of coordinated allocation four-wheel, if but the pattern of 4 wheel driven is still taked when Smaller load travels, the energy ecology of automobile can be deteriorated, continual mileage shortens, simultaneously, the cornering properties of automobile can not adjust in real time, and automobile cannot be made to have good rideability when low speed and high speed.Also such as " vehicle high-speed four-wheel steering stabilizing device and control method thereof " notification number: CN201310720765.8 patent of invention, this technology refer to automobile trailing wheel when high speed turns to has appropriate angle of following to be tending towards understeer characteristics to make vehicle, the generation of whipping accident can be reduced, but but can not solve the problem that automobile low speed needs the large turning of minor radius, cannot complex road condition be adapted to.
Utility model content
The utility model mainly solves the technical matters existing for prior art; Provide a kind of battery-driven car that can make and have good dynamic property, traveling comfort and road-holding property, that can also improve electric vehicle energy service efficiency has the battery-driven car entirely turned to real-time 4 wheel driven function simultaneously.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals:
There is the battery-driven car entirely turned to real-time 4 wheel driven function, it is characterized in that, comprise chassis, the wheel be arranged on chassis, be the near front wheel, off front wheel, left rear wheel and off hind wheel respectively; Described four inside wheels are all equipped with wheel hub motor, and each wheel hub motor all drives corresponding wheel; Four wheels are all provided with the steering swivel, track arm and the tierod that connect successively; Tierod one end connection that front tooth bar one end is corresponding with the near front wheel, tierod one end that the front tooth bar other end is corresponding with off front wheel connects; The tierod that tierod one end corresponding with left rear wheel, rear tooth bar one end connects, the rear tooth bar other end is corresponding with off hind wheel is connected; The front gear engaged with front tooth bar is connected with bearing circle by transmission shaft, and the backgear engaged with rear tooth bar is connected with stepper motor output shaft; Described wheel hub motor and stepping motor control by controller.
Therefore, the utility model tool has the following advantages: the cornering properties that 1, can adjust battery-driven car in real time, and the negative understeer characteristic increasing battery-driven car during low speed as required can make the minimum turning radius of battery-driven car reduce, and is convenient to adapt to complex road condition; Make battery-driven car have understeer characteristics during high speed, be convenient to reduce electric vehicle rotary to time whipping danger.2, chaufeur adjusts drive pattern as required in real time, and when four wheel drive, electrical vehicular power is more sufficient, and when two-wheel drive, energy ecology is higher, and continual mileage is longer.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present utility model.
Detailed description of the invention
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.In figure, the near front wheel 1, front gear 2, tierod 3, off front wheel 4, front tooth bar 5, transmission shaft 6, track arm 7, steering swivel 8, bearing circle 9, left rear wheel 10, stepping motor 11, rear tooth bar 12, backgear 13, off hind wheel 14.
Embodiment:
The utility model comprises chassis, the wheel be arranged on chassis, is the near front wheel 1, off front wheel 4, left rear wheel 10 and off hind wheel 14 respectively; Described four inside wheels are all equipped with wheel hub motor, and each wheel hub motor all drives corresponding wheel; Four wheels are all provided with the steering swivel 8, track arm 7 and the tierod 3 that connect successively; Tierod 3 one end corresponding with the near front wheel 1, front tooth bar 5 one end connects, and tierod 3 one end that front tooth bar 5 other end is corresponding with off front wheel 4 connects; Rear tooth bar 12 one end tierod 3 one end connect, rear tooth bar 12 other end with off hind wheel 14 corresponding tierod 3 corresponding with left rear wheel 10 is connected; The front gear 2 engaged with front tooth bar 5 is connected with bearing circle 9 by transmission shaft 6, and the backgear 13 engaged with rear tooth bar 12 is connected with stepping motor 11 output shaft; Described wheel hub motor and stepping motor control by controller.
Described has the battery-driven car entirely turned to real-time 4 wheel driven function, when bearing circle rotates to a direction, front gear 2 can be driven to rotate to a direction by transmission shaft 6, front gear 2 can drive front tooth bar 5 to move to a direction, front tooth bar 5 can pull the track arm 7 of left and right wheels by tierod 3, thus front vehicle wheel achieves turning to some directions; When stepping motor 11 rotates to a direction, backgear 13 can be driven to rotate to a direction, backgear 13 can drive rear tooth bar 12 to move to a direction, rear tooth bar 12 can pull the track arm 7 of left and right wheels by tierod 3, thus rear wheel achieves turning to some directions.
