Abstract

The invention provides a bicycle. The bicycle can be driven in a manner that a person sits or stands on the bicycle and steps on pedals left and right and up and down with the two feet. The drive manner better accords with the features of human engineering. The bicycle is simple and reliable in structure, and the high running speed can be obtained. The bicycle is mainly composed of the following basic structures including a front wheel with a bicycle head and a bicycle fork, a bicycle frame and a rear wheel. A transmission shaft is arranged at the coaxial end of a rotary shaft of the rear wheel. The rear wheel is driven through a speed change transmission gear and a flywheel. Each of the left end and the right end of the transmission shaft extends out to be provided with a swing rod through an overrun one-way clutch. The other end of each swing rod is provided with one movable pedal. A pulley is arranged on the bicycle frame. The two ends of a flexible transmission belt are wound around the pulley and then connected with the left swing rod and the right swing rod, so that the two swing rods swing in the opposite directions synchronously in the swinging process. When the person rides the bicycle in a sitting posture, a seat is additionally arranged. When riding the bicycle in a standing manner, the person can directly step on the movable pedals of the left swing rod and the right swing rod with the two feet.

Description

A kind of bicycle

Technical field

The present invention relates to a kind of bicycle, particularly a kind of bicycle being available for users to sit or the mode both legs of the standing mode of trampling drives.

Background technology

Various employing human bodies currently a popular on market are to sit or the bicycle driven in the both legs mode of trampling of standing, two big classes can be divided into: a class is to adopt intermittently-driving mode by the basic kind of drive, namely two lower limbs drive different drive mechanisms respectively when stepping on pedal, this structure is simpler, take small volume, but transmission efficiency is relatively low. Another kind of for traditional bicycle transmission structure, namely step on crank mechanism rotating 360 degrees by two lower limbs and drive chain drum and chain drive trailing wheel, this structure drives stroke to fix, but the change in the meeting generation moment cycle obtained when rotation is turned around, especially to drive in the mode of standing time owing to there is transmission dead point, therefore transmission efficiency is not too high.

As the bicycle to sit or the mode of standing drives, above existing these drive drive mechanism, have some shortcomings in various degree in volume, drive mechanism and type of drive, also not ideal enough especially with the structure driving bicycle in the mode of standing. As everybody knows, the mankind are through long-term natural evolution, according to human engineering, human body in running mainly by swing up and down before and after both legs carry out walking or come realize, therefore, for the bicycle driven in the mode of standing can reach the speed of service and meet human engineering motion mode faster, and there is less volume and simple structure, it is convenient for carrying and collects, it may be that this can sit or the mode of standing drives the main development direction of bicycle.

Summary of the invention

The present invention provides a kind of bicycle, it is possible to adopting human body to sit or mode of standing, the bicycle that the mode stepped on up and down about both legs drives, type of drive more meets the feature of human engineering, simple and reliable for structure, can obtain the speed of service faster.

In order to achieve the above object, one bicycle of the present invention is mainly made up of following basic structure: with the front-wheel of headstock and fork, vehicle frame, trailing wheel, at the same axle head of trailing wheel rotating shaft equipped with power transmission shaft, trailing wheel is driven by speed changing transmission gear and flywheel, the two ends, left and right of power transmission shaft protrude through and surmount one-way clutch respectively equipped with a fork, the other end of fork is respectively equipped with Active foot plate, vehicle frame is provided with a pulley, article one, the two ends of flexible driving band, are connected with two, left and right fork after pile warp pulley, make two forks synchronize when swinging to swing in the opposite direction.Adopting and add seat during riding in sitting posture, when adopting the mode of standing to ride, two lower limbs directly step down on the Active foot plate of two forks in left and right.

Its concrete structure of a kind of bicycle of the present invention has following characteristics: one is the coaxial configuration adopting hind axle with power transmission shaft, concentrates in trailing wheel by transmission, gear and flywheel, simple and reasonable, and is not take up the external space of bicycle. Two is that two, left and right fork maintains synchronous hunting by flexible driving band and the pulley being contained on vehicle frame. Three is that the type of drive that this both legs are stepped on up and down does not drive dead point, no matter is that degree can drive bicycle in the way of maximum moment in the way of sitting or standing.

Wherein: trailing wheel employing axletree is coaxially arranged with power transmission shaft, and trailing wheel is built with gear and flywheel simultaneously;

Wherein: two, left and right fork is with rear axis for centre swinging, by flexible driving band through pulley synchronous backward synchronous hunting;

Wherein: left and right fork is each connected with the power transmission shaft of trailing wheel coaxial core by surmounting one-way clutch;

Wherein: power transmission shaft stretch out two ends are installed surmount one-way clutch and can substitute with unilateral bearing;

Wherein: seat can be loaded onto on vehicle frame, bicycle is made can to ride in the way of riding seat;

Accompanying drawing explanation

Fig. 1 is the basic block diagram of a kind of bicycle of the present invention.

Detailed description of the invention

A kind of bicycle, by the headstock 1 controlling turning of bicycle, front-wheel fork 2, front-wheel 3, vehicle frame 4, trailing wheel 14, power transmission shaft 13 is had to stretch out at the two ends of trailing wheel shaft core, left swing bar 8 and right fork 11 are connected with power transmission shaft 13 respectively through surmounting one-way clutch 12, left swing bar 8 is all connected with the two ends of a flexible driving band 10 with right fork 11 simultaneously, flexible driving band 10 is also cross the pulley 5 of the flexible driving band being arranged on vehicle frame 4, left Active foot plate 7 and right Active foot plate 9 it is separately installed with in the end of left swing bar 8 and right fork 11, at the same axle head of trailing wheel rotating shaft equipped with power transmission shaft 13, trailing wheel 14 is driven by speed changing transmission gear and flywheel.

During use, onboard, both hands buttress headstock, and two lower limbs stand on the Active foot plate of left and right respectively, and during walking, both legs replace pushes pedals at people just station, drive trailing wheel to rotate by left and right fork through surmounting one-way clutch and gear and flywheel, make bicycle quickly forward.
