Abstract
The utility model belongs to bicycle, in particular to a front driving device for bicycle, tricycle, and electric bicycle and other front driving device, including a front fork, a flywheel mechanism, a turntable, a pedal mechanism and a chain, which is characterized in that the driving device is arranged on the front fork and makes up of the front driving device. The utility model has some useful effect: the mechanism makes use of the mechanical principle to change the rear driving device of the bicycle into the front driving device, and therefore moves the center of gravity forward, and then lightens sciatic pressure, finally saves the labor of riders.
Description
Technical field
The utility model belongs to bicycle, relates in particular to a kind of preceding driving device that is applied to bicycles such as bicycle, three-wheel vehicle, Electrical Bicycle, three-wheel vehicle.
Background technology
At present, the driving of bicycle or three-wheel vehicle all is rear drive.That is, trailing wheel is the active opinion, and the bicyclist scrunches pedal and rotates by the flywheel on wheel disc, chain and the trailing wheel, drives front-wheel and moves ahead.This rear drive configuration, because the center of gravity of riding all drops on buttocks, the bicyclist is tired easily, the anterior blood of buttocks freely pathology can not occur.
The utility model content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and a kind of preceding driving device of bicycle is provided, and changes rear drive into before driving, and the bicyclist can be moved forward center of gravity, alleviates the pressure to buttocks.
The utility model for achieving the above object, by the following technical solutions: a kind of preceding driving device of bicycle, comprise preceding wooden fork, contain flywheel mechanism, the actuating device of wheel disc, pedal mechanism and chain, it is characterized in that: constitute front driving device on the wooden fork before described actuating device places.
The left and right sides pedal mechanism and the front axle of riveted joint wheel disc are affixed in the described front driving device, at the aforementioned wheel disc homonymy of the front axle skin flywheel mechanism that is spirally connected, and before homonymy affixed wheel disc speed reduction gearing on the wooden fork pipe.
Described wheel disc speed reduction gearing comprises bearing seat, bearing, axle and big or small speed change wheel disc, and described bearing places on the axle, and is fixed in the bearing seat, at the above-mentioned wheel disc and the affixed big or small speed change wheel disc of flywheel homonymy difference of bearing seat.
The beneficial effects of the utility model: it is to utilize mechanics principle, and the rear drive equipment of bicycle is become front driving device, and the bicyclist can be moved forward center of gravity, alleviates the pressure to buttocks.The bicyclist rides more laborsaving.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Describe the specific embodiment of the present utility model in detail below in conjunction with accompanying drawing and preferred embodiment.
As shown in the figure, a kind of preceding driving device of bicycle, contains the actuating device of flywheel mechanism 3, wheel disc 2, pedal mechanism 4 and chain 8 at wooden fork 1 before comprising, constitutes front driving device on the wooden fork before described actuating device places.The left and right sides pedal mechanism and the front axle 5 of riveted joint wheel disc are affixed in the front driving device, at the aforementioned wheel disc homonymy of front axle skin 6 flywheel mechanism 3 that is spirally connected, and before homonymy affixed wheel disc speed reduction gearing 7 on the wooden fork pipe.The wheel disc speed reduction gearing comprises bearing seat 7-1, bearing 7-2, axle 7-3 and big or small speed change wheel disc 7-4,7-5, and described bearing places on the axle, and is fixed in the bearing seat, at the above-mentioned wheel disc and the affixed big or small speed change wheel disc of flywheel homonymy difference of bearing seat.Bearing seat is welded on the preceding wooden fork pipe.Wheel disc speed reduction gearing reduction ratio is 2.5: 1.Front driving device is installed, and it is promptly rideable to load onto chain.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
Claims (3)
