Abstract
The utility model discloses a double-sprocket driven bicycle which is respectively driven by two chains. A user rides on a saddle in a half back leaning type, and the back leans on a back cushion to obtain pedaling drive. Labor saving, no fatigue and speed acceleration are obtained. A bicycle frame is provided with a pedaling wheel which is composed of a pedal axle, a pedal wheel plate and pedals. The back end is provided with a middle axle which is composed of an outer shell of the middle axle. A rolling bearing and the middle axle are arranged in the outer shell, one side is provided with a driving small sprocket of the middle axle and one side is provided with a driving big sprocket of the middle axle. One driving chain is connected with the pedal wheel plate and the driving small sprocket of the middle axle for drive, and the other driving chain is connected with the big sprocket of the middle axle and a flywheel of the central position of the back wheel for drive. The user rides on the bicycle to pedal the pedals to drive a front chain to be driven to the middle small sprocket which drives a back chain and the flywheel for drive. The structure is simple.
Description
Affiliated technical field
The utility model relates to a kind of double-stranded wheel driving bicycle, specifically uses two chain sprocket drive, drives bicycle walking, belongs to bicycle drive technology field.
Background technology
At present, public bicycle transmission is by the transmission of strand bar, the people rides on the vehicle seat two legs and is vertical configuration and pedals stretcher and firmly make bicycle band people walking, people's waist tendon is not used strength like this, so riding speed is slow, effort, crotch's fatiguability, though the design of this bicycle has continued constant for many years, people have become a kind of custom.
Summary of the invention
In order to overcome existing bicycle people fatiguability, the deficiency that scanning frequency is slow, the utility model provides a kind of double-stranded wheel driving bicycle, by two chain gears, the people rides on the vehicle seat with half backstroke respectively for it, and back relies on rear back mat, ride transmission, both laborsaving not tired, pick up speed again.
The technical scheme that its technical matters that solves the utility model adopts is: on the end floor beam pedal wheel is installed under crossbeam, pedal wheel is made up of pedal axle, pedal roulette and step tread plate; Axis is installed in its back-end, and this axis is by middle shaft housing, and antifriction-bearing box and axis are adorned in the two ends in the shell, and axis one side is equipped with middle shaft drive minor sprocket, and the opposite side of axis is equipped with middle shaft drive hinge wheel, and large and small sprocket wheel is fixed by set pin; Article two, one of messenger chain is contained on pedal roulette and the middle shaft drive minor sprocket, another is contained on the flywheel of middle shaft drive hinge wheel and rearmost end, pedal pedal axle rotation drive pedal roulette on stretcher rotates and drives preceding chain gear, preceding chain rotates axis, drive the middle shaft drive hinge wheel of opposite side, rear chain on the hinge wheel drives flywheel and rotates walking, double-stranded wheel driving bicycle starting operation.
The beneficial effects of the utility model are: utilize the transmission of double-stranded wheel, light, fast, it is simple in structure, and is reasonable in design.
