Abstract

A bicycle without a handlebar or a chain comprises a front wheel, two rear wheels, a front fork and pedals. The front wheel is equipped with an coaxial variable speed transmission device, the coaxialvariable speed transmission device is equipped with a front shaft transversely penetrating through the axle center of the front wheel, the front shaft is equipped with the front fork which is connected with a soft band, the upper end of the front fork is connected with a front connecting rod, the front fork and the front connecting rod form a steering device, the rear end of the front connecting rod is connected with a rear connecting rod, the rear connecting rod is fixedly connected with a saddle, and the rear end of the rear connecting rod is divided towards the left end and the right end tobe respectively connected to the two rear wheels. The soft band replaces the handlebar, the coaxial variable speed transmission device replaces the chain, and then the bicycle can overcome shortagesbrought by a chain transmission device. The bicycle is simple in structure and is light, convenient, labor-saving and time-saving, and brings a new feeling of riding a horse when a rider rides the bicycle to advance.

Description

No handlebar Chainless bicycle

Technical field

The utility model relates to the bicycle and man technical field, is a kind of no handlebar Chainless bicycle specifically.

Background technology

Bicycle is a kind of noiseless, pollution-free, energy-conserving and environment-protective and the vehicle that can take exercises, is subjected to people's popular welcome.But traditional bicycle adopts handlebar to control direction and chain gear technology, chain gear often because of chain rupture, fall deficiencies such as chain, effort and make troubles to the rider, the designing requirement of handlebar both hands in process by bike can not leave handlebar all the time, like this when weather is colder, need connect when need carry out other operations when making a phone call, in by bike all very inconveniently, part rider usually meets accident because of not holding handlebar or holding bad handlebar.

The utility model content

The utility model is exactly to solve the problem that standard bicycle exists aspect handlebar and drive technology, adopts soft band to replace handlebar, replaces chain gear by coaxial variable-speed drive, and a kind of no handlebar Chainless bicycle is provided.

Technical matters of the present utility model adopts following technical proposals to solve:

A kind of no handlebar Chainless bicycle, comprise that a front-wheel, two trailing wheels, front forks reach foot-operated, coaxial variable-speed drive is housed on the described front-wheel, coaxial variable-speed drive is provided with a front axle and is horizontally through from the front wheel spindle heart, front fork is housed on the front axle, connect a soft band on the front fork, the front fork upper end connects a front rod, front fork and front rod are formed steering hardware, the front rod rear end connects a rear connecting rod, captive joint vehicle seat on the rear connecting rod, the rear end of rear connecting rod two ends to the left and right separately connect two trailing wheels respectively.

Described coaxial variable-speed drive comprises described front axle and flywheel, chuck and rides that front axle is horizontally through from the front wheel spindle heart, and a side of front axle is adorned a flywheel, the outside socket chuck of flywheel, described foot-operated being contained on the front axle.

Advantage of the present utility model is: do not have handlebar, by being installed in the soft band replacement handlebar of front fork to the vehicle seat position; Do not have chain, front-wheel is equipped with coaxial variable-speed drive, and this device has overcome the deficiency that chain gearing brought, and replaces chain gear with this; Adopt three wheels, guarantee that it operates steadily, safety.Simple in structure, friction little, light and handy convenience, time saving and energy saving as long as the rider is sitting on the vehicle seat during use, are held soft band, and both feet are pedaled foot-operated, and car can advance, and give rider's's a kind of " riding " novelty sensation simultaneously.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further elaborated:

A kind of no handlebar Chainless bicycle comprises that a front-wheel, two trailing wheels, front forks reach foot-operated.Coaxial variable-speed drive is housed on the front-wheel 1, coaxial variable-speed drive is provided with a front axle 11, be horizontally through from front-wheel 1 axle center, front fork 2 is housed on the front axle 11, be equipped with two little rings connects one and softly is with 3 at 5cm place, front fork bottom, front fork 2 upper ends connect a front rod 4, and front fork 2 and front rod 4 are formed steering hardware.Front rod 4 rear ends connect a rear connecting rod 13, by seat bar 9 captive joint vehicle seats 6, fix a hook 10 with screw on the seat bar 9 on the rear connecting rod 13, are used to hang softly be with 3.The rear end of rear connecting rod 13 two ends to the left and right separately connects two trailing wheels 7 respectively.

Coaxial variable-speed drive comprises front axle 11, flywheel 14, chuck 15, foot-operated 8, front axle 11 is horizontally through from front-wheel 1 axle center, fixing by bowl group 12, one side of front axle 11 is adorned a flywheel 14, flywheel 14 outside socket chucks 15, the two ends of front axle 11 connect foot-operated 8, rotate by foot-operated 8 chucks 15 that drive on the front axle 11, and then drive flywheel 14 rotates, drive the purpose that front-wheel moves ahead thereby reach, and replace chain gear with this, because chuck 15 is fixed on the front axle 11, thereby current axis 11 can realize that the front-wheel independent rotation moves ahead when not rotating.

Claims
