Abstract
A kind of spring chain tooth bar stepless speed changes devices, have employed novel " not closing spring chain tooth bar and taper cone pulley rotary combined device ", by the not closing spring chain tooth bar arranged in cone, do the slideway motion expanding or reduce diameter, adjustment cone pulley, up and down apart from large or little, makes minor sprocket acceleration or deceleration." a kind of spring chain tooth bar stepless speed changes devices " for existing bicycle, should can realize gear stepless speed changing, overcome existing gearbox weight large; Size is large; Baroque shortcoming.
Description
The present invention relates to " a kind of latch plate chain tooth bar stepless speed changes devices ", is that the present inventor is about the innovation and creation proposed on February 14th, 2012 " one is closed gear combined tooth number change device not " by name; Application number is 201210032103.7; The applying date is the basis applied for a patent on February 14th, 2012 is transformed form.What " one is closed gear combined tooth number change device not " adopted is erose assembly, during rotation, two gears produce the eccentric inertial force of original text with regard to disequilibrium,, directly affects speed change and high speed rotation, disadvantage that Here it is " one is closed gear combined tooth number change device not ".
" a kind of latch plate chain tooth bar stepless speed changes devices " proposed by the invention just solves above shortcoming, original " closed irregular gear assembly " make into " arbitrarily can change the latch plate chain rack combination of radius of a circle " steady in the running, processing ease when accelerating and slow down, substantially increases rotational speed.
" a kind of latch plate chain tooth bar stepless speed changes devices " provided by the present invention, by bottom cone 1, cone top 2, upper cone axle 3, lower cone 4, the mechanism that forms of lower cone axle 5, toothed chain slideway 6, latch plate toothed chain bar 7, toothed chain head-clamp plate 8, chain 9, minor sprocket 10 and chainlet wheel shaft 11.Structure characteristic of the present invention and object is further illustrated below in conjunction with accompanying drawing.
Brief Description Of Drawings:
Fig. 1, Fig. 2, Fig. 3, Fig. 4 are the basic structure schematic diagram for " a kind of latch plate chain tooth bar stepless speed changes devices " provided by the present invention; Also be the schematic diagram of scalable latch plate chain tooth bar.
Fig. 5, Fig. 6, Fig. 7, Fig. 8 are the scalable chain tooth bar speed change schematic diagram of " a kind of latch plate chain tooth bar stepless speed changes devices " provided by the present invention; Also be that scalable latch plate chain tooth bar makes the infinite variable speed action schematic diagram of minor sprocket.
Please see Figure 1, shown in Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, its be mainly with on cone 1 one not closing spring plate chain tooth bar 7 strained by the toothed chain head-clamp plate 8 at two, be wrapped in cone 1; When cone about 1 vibration, make not closing spring plate chain tooth bar and expand or reduce the motion of diameter, and be engaged with chain 9; When cone about 1 rotates vibration, not closing spring plate chain tooth bar 7 is driven to rotate, all the time be engaged with chain 9, closing spring plate chain tooth bar 7 can the size of corresponding change diameter under the effect on cone 1 inclined-plane when cone about 1 vibration, makes chain 9 drive minor sprocket 10 stepless change.By chainlet wheel shaft 11 Power output.When cone 1 is down promoted by top 2, closing spring plate chain tooth bar 7 does not expand diameter under the effect progressively on cone inclined-plane, changes with minor sprocket 10 tooth ratio, makes minor sprocket 10 add the number of turns of rotation.When cone 1 is up promoted from end step 4, closing spring plate chain tooth bar 7 does not reduce diameter under the progressively effect on cone inclined-plane, and the tooth ratio of minor sprocket 10 is changed, and makes minor sprocket 10 decrease the number of turns of rotation.
Of the present invention execute example one of: " a kind of latch plate chain tooth bar stepless speed changes devices ", for bicycle gearshift, can realize gear stepless speed changing, slewing range is wide; Experiment proves that this device can change arbitrarily and rides travelling speed; Slewing range greatly and easily operate; Grade ability is strong; Speed-raising is fast; Etc. advantage.
