Abstract
The utility model provides a boosting bicycle which is an improvement on a common bicycle. A direction handle is provided with a bracket provided with a big chain wheel, the big chain wheel provided with a crank is connected with a small chain wheel arranged on a front wheel shaft through a chain, and the construction of the front wheel shaft is similar to that of a rear wheel shaft. The utility model has the advantages of simple structure, practicality and low cost.
Description
The utility model relates to bicycle.
Existing bicycle is required great effort, speed is slower, and is painstaking when particularly going up a slope.Existing usefulness is set up the gear formula or is made the morpet of power-assist power with driving engine, but the cost height, complex structure.
The purpose of this utility model provides a kind of cost power-assisted acceleration bicycle low, simple in structure.
Above-mentioned purpose is realized by following technical proposals: it comprises ordinary bicycle, be characterized on handle-bar, establishing a support, load onto a hinge wheel on this support, this sprocket wheel links to each other with minor sprocket on the front truck wheel shaft by chain, hinge wheel is provided with crank, and the structure of front truck wheel shaft adopts the structure of rear vehicle shaft.
Because the utility model simply improves dexterously, rear axle need only be transplanted on the front axle, makes front axle that minor sprocket also be arranged, and need only install a hinge wheel on handlebar, just can drive minor sprocket by chain, promptly can be by hand realization f-w-d.Front and back wheel all drives like this, reaches power-assisted and quickens.
Below in conjunction with drawings and Examples add have a talk about bright:
Fig. 1 is a structural representation of the present utility model
As shown in Figure 1, the utility model is improved on ordinary bicycle 1, and the structure of front wheel spindle 3 adopts the hind axle structure.Load onto support 7 on handle 2, support is provided with a hinge wheel 4, has crank 6, and hinge wheel rotates by the minor sprocket 8 that chain 5 drives on the front axle 3, realizes that front-wheel also drives.Reaching power-assisted quickens.
Claims (1)
1, a kind of power-assisted acceleration bicycle is characterized in that: mainly on handle-bar establish a support, and a big chain of adorning on this support, this sprocket wheel links to each other with minor sprocket on the front truck wheel shaft by chain, and big ingot is taken turns and is provided with crank.
