Description
Technical field
The invention belongs to technical field of bicycles, it is related to one kind no chain folding bicycle.
Background technology
Bicycle is the articles for daily use of people.Mainly use chain type and gear drive.Linked transmission has system
Make simple, the advantages of convenient to install and maintain, but linked transmission exist easily stain medicated clothing, de- chain, transmission efficiency high the shortcomings of,
And chain type transmission structure take up room greatly, to lay particular stress on not light, structure not compact, be particularly not easy to fold.
With the raising of people's living standard, the enhancing of low-carbon environment-friendly and green health consciousness, bicycle is subject to people once again
Favor.But it is as that urban transportation is increasingly crowded, it is substantially not enough to deposit parking space, along with bicycle is easily stolen, this
A little problems have impact on the enthusiasm that people cycle trip again.Then people have invented folding bicycle, in the hope of do not ride in stroke when
Section can be easy to carry, can save parking space when depositing again.
For example: Publication No. cn202337313u, the China of entitled " one kind no chain drive small wheel-diameter folding bicycle "
In patent, the drive system of this folding bicycle adopts gear transmission structure.Described gear transmission structure is tied for Helical gear Transmission
Structure.Be provided with a pair of helical gear in bicycle middle shaft, bicycle rear axle be provided with another to helical gear, the two pairs of helical gears pass through power transmission shaft
Connect.The helical gear being connected with bicycle rear axle drives internal speed-changing assembly.Folder is arranged on girder.The present invention passes through gear
Actuating device substitutes chain drive, small-wheel-diameter speed-changeable folding bicycle can be avoided to install common-use size variator ground clearance too near
Easily collision causes the shortcoming deforming, and also makes car load profile more aesthetically pleasing.
No chain folding bicycle using such technology uses and folding square Portable belt it is of course possible to ride, but still has
Following shortcoming:
A. its folding rotary shaft is located on the girder of bicycle and is laterally folded, and this undoubtedly can reduce bicycle girder
Security reliability or the material to folder, performance are put forward higher requirement, thus improve the cost of production.
B. its front and rear wheel is the steamboat of isodiametric 10-20 inch, can determine whether from daily experience: this is usually child
The size of car, adult rides painstaking.
C. chain is replaced to be in transmission connection by power transmission shaft between its foot-operated drive mechanism and rear wheel gear drive mechanism,
Transmission link is still more, and it is still larger to take vehicle body space, easy break-down and transmission efficiency is still relatively low.
In sum, the no chain folding bicycle of prior art uses in the side such as safety, reliability, efficiency of riding
Face is all not enough, and using effect is preferable not enough.
Content of the invention
For overcoming the deficiencies in the prior art, a kind of present invention safety of offer is higher, reliability is higher, ride efficiency more
Height, using effect more preferably no chain folding bicycle.
