Abstract
The invention discloses a bicycle gear speed-change device, wherein a novel 'single-tooth gear and unclosed gear rotary combined device' is used, an unclosed single-tooth gear capable of reciprocating in a slide way is installed in an unclosed gear, and a small chain wheel can be accelerated or decelerated according to the length of a chain supported by a single tooth by adjusting the reciprocating distance. The 'bicycle gear speed-change device' is used for the existing bicycle and capable of realizing gear stepless speed change, and overcomes the defects of high weight, large dimensions and complex structure of the existing transmission.
Description
The present invention relates to a kind of bicycle gears transmission system.That the inventor is " one is closed gear combined tooth number change device not " (application number: 201210032103.7 about the invention and created name proposing on February 14th, 2012; The applying date: on 02 14th, 2012) principle basis on transform and form.What " one is closed gear combined tooth number change device not " adopted is the combination of two not closed gears and chain, and rotation gets up to operate more complicated; Volume is large; Weight is large.The disadvantage that Here it is " one is closed gear combined tooth number change device not ".
The present invention's " a kind of bicycle gears transmission system " has just solved above shortcoming, original " two not closed gears and chain combination ", make the device of " not closed gear of list makes single-tooth gear and single-chain combination into another not closed gear " into, simple to operate when rotation; Volume ratio dwindled originally; Weight alleviates greatly.
It is a kind of mechanism being made up of not closed single-tooth gear 1, monodentate 2, single-tooth gear bottom 3, guide groove slideway 4, guide groove slideway bottom 5, cover plate 6, not closed gear wheel shaft 7, not closed gear 8, chain 9, minor sprocket 10, chainlet wheel shaft 11 for " a kind of bicycle gears transmission system " provided by the present invention.Further illustrate architectural feature of the present invention and object below in conjunction with accompanying drawing.
Brief Description Of Drawings:
Fig. 1, Fig. 2, Fig. 3, Fig. 4, be the left-hand revolution low speed rotation schematic diagram of " a kind of bicycle gears transmission system " provided by the present invention.
Fig. 4, Fig. 5 are that the left-hand revolution of " a kind of bicycle gears transmission system " provided by the present invention is from low speed toward high speed transition activities schematic diagram.
Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9 are the left-hand revolution High Rotation Speed schematic diagrams of " a kind of bicycle gears transmission system ".
Figure 10, be the internal organs view of " a kind of bicycle gears transmission system ".
By reference to the accompanying drawings 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Figure 10 is characterized in that: in not closed gear 8, have single-tooth gear 1 and monodentate 2 in guide groove slideway 4, to reciprocatingly slide, in the process of rotation, past far away with guide groove slideway bottom 5 reversing sense pull distance to not closed single-tooth gear 1 and monodentate 2, monodentate 2 is propped up chain 9 that come just larger with distance length not closed gear 8, the number of turns that minor sprocket 10 is turned is just more, has played accelerating action; Otherwise toward nearer with the direction pull distance of guide groove slideway bottom 5, monodentate 2 is propped up chain 9 that come just less with distance not closed gear 8 not closed single-tooth gear 1, the number of turns that minor sprocket 10 is turned is fewer, has played deceleration effort.
Advantage of the present invention is that the machineries such as bicycle have adopted this device can make complete machine weight saving, and size reduction and simple in structure experimental results show that this device can change arbitrarily riding speed; Speed range is large; Easy to operate.
Claims (3)
1. " a kind of bicycle gears transmission system " provided by the present invention, it is a kind of mechanism being made up of not closed single-tooth gear 1, monodentate 2, single-tooth gear bottom 3, guide groove slideway 4, guide groove slideway bottom 5, cover plate 6, not closed gear wheel shaft 7, not closed gear 8, chain 9, minor sprocket 10 and chainlet wheel shaft 11.
" a kind of bicycle gears transmission system " according to claim 1 by reference to the accompanying drawings 1, shown in Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Figure 10, it is mainly in not closed gear 8, to have single-tooth gear 1 and the monodentate 2 can be at the interior crank motion of guide groove slideway 4, in rotary course, past far away with guide groove slideway bottom 5 reversing sense pull distance to not closed single-tooth gear 1 and monodentate 2, monodentate 2 is propped up chain 9 that come just larger with distance length not closed gear 8, the number of turns that minor sprocket 10 is turned is just more, has played accelerating action; Otherwise toward nearer with the direction pull distance of guide groove slideway bottom 5, it is less that monodentate 2 props up chain 9 distance with not closed gear 8 of coming, and makes the number of turns turning of minor sprocket 10 fewer, played deceleration effort not closed single-tooth gear 1.
3. can be arranged to the rotating wheel of cylinder according to the monodentate 2 of " a kind of bicycle gears transmission system " described in power claim 1 and 2, to adapt to speed range.
