Description
Technical field
The utility model relates to the speed reducing driving device of a kind of Vidacare corp, particularly a kind of battery-driven car.
Background technology
In existing battery-driven car,, generally all use the first class reducer structure or directly utilize drive motor to drive trailing wheel and rotate for minimizing takes up room, simplified structure and expendable weight.The defective of this type of drive is that the diametral load that is subjected to of motor is bigger, and the various situations of ground-surface change directly impact motor, influences the service life of motor.The running that changes motor because of surface resistance simultaneously influences greatly, makes motor can not be in best running state, can not bring into play maximum power.
The utility model content
The purpose of this utility model is to provide a kind of actuating device of battery-driven car, and it has the structure of double reduction.
The actuating device of battery-driven car of the present utility model comprises drive motor, speed reduction gearing and flywheel.Described drive motor is fixed on the vehicle frame, and the output shaft of motor is as the input shaft of speed reduction gearing; Described flywheel is coaxial to be fixed on the back wheels of vehicle, and is connected with the output wheel of speed reduction gearing is coaxial.Wherein, this above-mentioned speed reduction gearing is a two reduction gear, the wheel for inputting of this speed reduction gearing is coaxial to be fixed on the motor shaft, wheel for inputting connects the one-level output wheel by belt, the one-level output wheel is captiveed joint by tween drive shaft is coaxial with the secondary wheel for inputting, and this tween drive shaft is fixed on the vehicle frame by bearing and middle pedestal; The secondary wheel for inputting connects the speed reduction gearing output wheel by belt, this output wheel by bearing fixing on hind axle.
The wheel for inputting of this above-mentioned speed reduction gearing, one-level output wheel, secondary wheel for inputting and output wheel can respectively be gears, and the belt of this speed reduction gearing can respectively be the belt that the inboard has tooth, and the tooth of this belt inboard can with gear mesh; The wheel for inputting of this speed reduction gearing, one-level output wheel, secondary wheel for inputting and output wheel also can respectively be that light is worn wheel; The belt of this speed reduction gearing also can be common light musculus cutaneus band.
The actuating device of above-mentioned battery-driven car of the present utility model, pass through two reduction gear, overcome the defective of motor direct-drive or one-level deceleration mechanism, the road surface changes the various impacts that produce, through acting on motor after the two reduction gear buffering, alleviate the impact that motor is caused greatly, can prolong the service life of drive motor.Can make simultaneously motor be in best running state all the time, give full play to the power output of motor.
Description of drawings
Fig. 1 is the side-looking structural representation of the utility model actuating device;
Fig. 2 is that A-A is to cross-sectional view.
The specific embodiment
Actuating device of the present utility model as shown in Figure 1, present embodiment are that this actuating device is applied on the Electrical Bicycle.On vehicle frame, and drive motor 2 is fixed on this drive motor support 1 by screw retention for drive motor support 1, and the coaxial gear 3 that is fixed with on the output shaft 13 of drive motor, this gear 3 are just as the wheel for inputting of speed reduction gearing.The tween drive shaft 12 of speed reduction gearing by bearing fixing on tween drive shaft bolster 5, bearing frame 5 is fixed on the vehicle frame, the coaxial gear 6 of fixing of one end of this tween drive shaft 12, output wheel as the one-level deceleration, this gear 6 is provided with tooth by the inboard belt 4 is connected with gear 3, so that the transmission of power of gear 3 is given gear 6.The coaxial gear 7 of fixing of the other end of tween drive shaft, secondary wheel for inputting as speed reduction gearing, the secondary output wheel 9 of speed reduction gearing is the output wheel of speed reduction gearing as a whole, it also is a gear, the gear 9 of this output is coaxial to be connected with flywheel (not marking among the figure) unidirectional rotation, is fixed on the Electrical Bicycle trailing wheel 11 and flywheel is coaxial.Above-mentioned trailing wheel 11, output gear 9 and flywheel all by bearing fixing on rear axle 10, rear axle 10 is fixed on the vehicle frame.Gear 9 and gear 7 also interconnect by the toothed belt 8 in inboard, so that the transmission of power of gear 7 is to gear 9.
Be normal operation and the brake that guarantees above-mentioned Electrical Bicycle, also install brake 14 at the opposite side of trailing wheel 11.
Above-mentioned actuating device of the present utility model, after connecting motor power, motor 2 begins to rotate, and driven gear 3 rotations, and gear 3 rotates by belt driven gear 6, gives gear 6 and tween drive shaft 12 with transmission of power, and realizes the effect of one-level deceleration.Tween drive shaft 12 driven gears 7 rotate, and gear 7 rotates by belt 8 driven gears 9, realizes the effect of double reduction.Gear 9 drives unidirectional rotation bonded assembly flywheel rotation with it, and flywheel just drives trailing wheel 11 rotations of captive joint with it, realizes travelling of Electrical Bicycle.
Actuating device of the present utility model drives battery-driven car by two reduction gear and travels, and all various equivalent structure transformations that utilize above-mentioned feature all belong to protection domain of the present utility model.
