Abstract
A double drive wheel disc of an electric bicycle belongs to the technical field of bicycles, aiming to solve the problem of hard sledding of manpower drive. The technical scheme is that the wheel disc comprises an internal sleeve, a middle sleeve and an external sprocket wheel, which are sleeved from inside to outside, wherein the inner sleeve is fixed on a central shaft of an electric bicycle, and balls and a pawl are arranged between the internal sleeve and the central sleeve. The external sprocket wheel is connected with an output sprocket wheel of a motor through a chain, and balls and a pawl are arranged between the external sprocket wheel and the middle sleeve, a driving sprocket wheel is fixed on one side of the middle sleeve, and the driving sprocket wheel can form a driving relation with a bicycle flywheel through a chain. The double drive wheel disc can facilitate electric bicycles to be driven by manpower like a common bicycle, and greatly increases the comfort of driving the electric bicycles.
Description
Technical field
The utility model relates to a kind of wheel disc that manpower and motor power can be delivered to wheel that uses on Electrical Bicycle, belong to technical field of bicycles.
Background technology
At present, Electrical Bicycle mostly uses the hub-type motor, and the part of motor is rotated with wheel.When accumulator electric-quantity exhausts or circuit breaks down, when Electrical Bicycle is driven by manpower, the power of rider output not only will overcome the force of rolling friction of bearing and the force of sliding friction of carbon brush for electric machine, and a part also will change into the rotation function of motor, therefore can feel special effort.If existing Electrical Bicycle is improved, make drive Electrical Bicycle can be light as riding ordinary bicycle, must receive consumers in general's favor greatly.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of can make Electrical Bicycle as ordinary bicycle by the double dynamical wheel disc of manually driven Electrical Bicycle.
Problem described in the utility model realizes with following technical proposals:
The double dynamical wheel disc of a kind of Electrical Bicycle is made up of the interior cover of from-inner-to-outer suit successively, middle cover and outer chains wheel, overlaps fixed cover in described to be loaded on the axis of Electrical Bicycle, is provided with ball and ratchet between it and the middle cover; Described outside sprocket wheel is connected with the output chain gear of motor by chain, and and middle cover between be provided with ball and ratchet; A side of cover is fixed with drive sprocket in described, and described drive sprocket constitutes driving relationship by chain and bicycle freewheel.
The double dynamical wheel disc of above-mentioned Electrical Bicycle, described middle cover is made up of the cover plate of middle cover main body and one side, and described cover plate is connected with middle cover main body by screw thread.
In of the present utility model between cover and the interior cover, all constitute ratchet device between middle cover and the outside sprocket wheel, cover rotation during motor can drive by outside sprocket wheel and ratchet, then can rotate with stretcher bonded assembly axis by cover in interior cover and the ratchet driving, two kinds of actuating devices can work independently, also can work simultaneously, and be independent of each other; Middle cover is by being fixed in the output chain gear drive wheels rotation of one side.When accumulator electric-quantity exhausts or circuit breaks down, when Electrical Bicycle was driven by manpower, outside sprocket wheel and motor did not rotate, and resistance has only the force of rolling friction of bearing.The utility model can make Electrical Bicycle be driven by manpower like a cork as ordinary bicycle, has greatly improved the traveling comfort of riding Electrical Bicycle.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view.
Each label is among the figure: 1, outside sprocket wheel; 2, middle cover main body; 3, cover plate; 4, interior cover; 5, ball; 6, ratchet; 7, drive sprocket; 8, spring.
The specific embodiment
Referring to Fig. 1, outside sprocket wheel 1, middle cover, interior cover 4 are sleeved on together, earlier middle cover main body 2 are kept flat during assembling, ball, ratchet, interior cover 4 and outside sprocket wheel 1 are installed again, screw cover plate 3 then each part is fixed, the side of cover main body 2 gets final product in screw drive sprocket 7 being fixed at last.
Referring to Fig. 2, the outer rim of interior cover 4 and middle cover main body 2 all is equipped with the ratchet 6 of two symmetries, on the inner edge of outside sprocket wheel 1 and middle cover main body 2 tooth that is complementary with ratchet 6 is arranged, ratchet 6 abuts against the inner edge of outside sprocket wheel 1 and middle cover main body 2 under the promotion of spring 8, cover 4 and outside sprocket wheel 1 can only be with respect to middle interplanting folk prescription to rotations in making.In Fig. 2, if interior cover 4 left-hand revolutions, cover was with interior cover 4 left-hand revolutions during the ratchet 6 on interior cover 4 outer rims will promote, and the ratchet 6 on middle cover main body 2 outer rims is the externally inner edge of sprocket wheel 1 slip then, outside sprocket wheel 1 does not rotate, and the resistance of whole Electrical Bicycle is very little.
Claims (2)
1, the double dynamical wheel disc of a kind of Electrical Bicycle, it is characterized in that, it is made up of the interior cover (4) of from-inner-to-outer suit successively, middle cover and outside sprocket wheel (1), described in cover (4) fixed cover be loaded on the axis of Electrical Bicycle, be provided with ball (5) and ratchet (6) between it and the middle cover; Described outside sprocket wheel (1) is connected with the output chain gear of motor by chain, and and middle cover between be provided with ball and ratchet; A side of cover is fixed with drive sprocket (7) in described, and described drive sprocket (7) constitutes driving relationship by chain and bicycle freewheel.
According to the double dynamical wheel disc of the described Electrical Bicycle of claim 1, it is characterized in that 2, described middle cover is made up of the cover plate (3) of middle cover main body (2) and one side, described cover plate (3) is connected with middle cover main body (2) by screw thread.
