Abstract
The utility model relates to a bicycle. The utility model has the technical characteristic that on the basis of an ordinary bicycle, an intermediate transmission shaft of a chain wheel is additionally arranged on a bicycle frame and positioned between a driving chain wheel and a chain wheel of a pedal; a big chain wheel and a small chain wheel which are arranged on the shaft of a chain wheel are respectively connected with each other by the driving chain wheel and the chain wheel of a pedal; the big chain wheel is larger than the driving chain wheel; the small chain wheel is at least the same as the chain wheel of a pedal. The bicycle has the characteristic of labor saving and bicycle speed can be correspondingly improved.
Description
The utility model relates to a kind of bicycle.
At present, the bicycle of selling on the market has two types substantially.A kind of is standard bicycle with pedal axle upper sprocket wheel and rear drive sprocket wheel shaft cochain crop rotation chain gear; Another kind is the mountain bike of variable-ratio.The former since pedal axle upper sprocket wheel greater than rear drive sprocket wheel shaft sprocket wheel, comparatively painstaking during the pedal car, particularly run into when going up a slope more obvious; And the latter makes structure become complicated owing to set up speed-changing mechanism, and making and maintenance are all more bothersome.
At the deficiency that above-mentioned prior art exists, the purpose of this utility model provides a kind of simple in structure and laborsaving and can improve the bicycle of the speed of a motor vehicle.
The purpose of this utility model is achieved in that it comprises handlebar, vehicle seat, front forked frame, vehicle frame and place the front forked frame turning cylinder respectively and the vehicle frame rear portion with front vehicle wheel on the axle drive shaft and rear wheel and place sprocket wheel and the drive sprocket that places on the axle drive shaft on the pedal axle of vehicle frame middle part, it is characterized in that: between pedal axle and axle drive shaft, be provided with the intermediate drive sprocket shaft on the vehicle frame, set big on this sprocket shaft, little two driving chain wheels link to each other with pedal axle upper sprocket wheel with drive sprocket by chain respectively, hinge wheel on the intermediate drive sprocket shaft is greater than drive sprocket, and the minor sprocket on the intermediate drive sprocket shaft is equal to pedal axle upper sprocket wheel at least.
The utility model makes the rider feel laborsaving because the minor sprocket on the intermediate drive sprocket shaft is identical with pedal axle upper sprocket wheel, and hinge wheel can make the speed of a motor vehicle improve greatly greater than drive sprocket on the intermediate drive sprocket shaft simultaneously.
Below in conjunction with accompanying drawing the utility model is explained.
Accompanying drawing is the utility model structural representation.
By accompanying drawing as can be known, vehicle seat 2, handlebar 4, front forked frame 5 all links to each other with vehicle frame 3, front vehicle wheel 6 place front forked frame 5 bottoms with turning cylinder on, rear wheel 1 place vehicle frame 3 rear portions with axle drive shaft on, pedal 7 place vehicle frame 3 middle parts with the pedal axle on, between drive sprocket 14 and pedal sprocket wheel 8, be provided with intermediate drive sprocket shaft 10 on the vehicle frame 3, set two sprocket wheels 11 of size on this sprocket shaft, 12 respectively through chain 13,9 link to each other with pedal sprocket wheel 8 with drive sprocket 14, use the pedal pedal, just can drive minor sprocket rotation on the messenger chain wheel shaft by the pedal sprocket wheel, drive drive sprocket by the hinge wheel on the messenger chain wheel shaft simultaneously and rotate, drive the front vehicle wheel walking by rear wheel.Rear wheel among the figure is greater than front vehicle wheel, and purpose is a two-wheel distance before and after shortening, and front vehicle wheel is urinated in turning to flexibly.Hinge wheel 11 its diameters on the messenger chain wheel shaft 10 are greater than drive sprocket 14, the slightly larger in diameter of minor sprocket 12 in or equal pedal sprocket wheel 8.
Claims (1)
