Abstract
The invention discloses a stepless speed change device of a spring chain rack, which utilizes a novel unclosed spring chain rack and conical wheel rotation combining device. An unclosed spring chain rack arranged on a conical body acts slide way motion to increase or reduce the diameter, and a minor sprocket accelerates or decelerates by regulating the distance between the upper part and the lower part of a conical wheel. The stepless speed change device of the spring chain rack, which is disclosed by the invention, is applied to the existing bicycles, can realize gear stepless speed change, and overcomes the defects of large weight, large size and complex structure of the existing transmission.
Description
The present invention relates to " a kind of latch plate chain tooth bar stepless speed changes devices ", is that the inventor is about the innovation and creation that proposed on February 14th, 2012 " a kind of not closed Gear combination becomes number of teeth device " by name; Application number is 201210032103.7; The applying date is to transform on the principle basis of applying for a patent on February 14th, 2012 to form." a kind of not closed Gear combination becomes number of teeth device " what adopt is erose assembly, two gears produce the eccentric inertial force of original text with regard to disequilibrium during rotation,, directly influenced speed change and high-speed rotation, disadvantage that Here it is " a kind of not closed Gear combination becomes number of teeth device ".
" a kind of latch plate chain tooth bar stepless speed changes devices " proposed by the invention just solved above shortcoming, original " not closed irregular gear assembly " made into the latch plate chain tooth bar of radius of a circle " can arbitrarily change combination " steady in the running, processing ease when acceleration and deceleration has improved rotational speed greatly.
" a kind of latch plate chain tooth bar stepless speed changes devices " provided by the present invention, the mechanism that is formed by cone 1, cone top 2, epicone axon 3, lower cone bottom 4, 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.Further specify structure characteristic of the present invention and purpose below in conjunction with accompanying drawing.
Brief Description Of Drawings:
Fig. 1, Fig. 2, Fig. 3, Fig. 4 are the basic structure schematic representation for " a kind of latch plate chain tooth bar stepless speed changes devices " provided by the present invention; It also is the schematic representation of scalable latch plate chain tooth bar.
Fig. 5, Fig. 6, Fig. 7, Fig. 8 are the scalable chain tooth bar speed change schematic representation 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 representation of minor sprocket.
Please see Figure 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, shown in Figure 8, its mainly on cone 1, be with one not closing spring plate chain tooth bar 7 be wrapped on the cone 1 by toothed chain head-clamp plate 8 tensions at two; Go here and there up and down when moving in cone 1, do that closing spring plate chain tooth bar not enlarges or the motion of diameter reduction, and and chain 9 interlocks; Cone 1 is rotated up and down and is gone here and there when moving, drive not closing spring plate chain tooth bar 7 rotations, all the time with chain 9 interlocks, not closing spring plate chain tooth bar 7 can cone 1 go here and there up and down when moving under the effect on cone 1 inclined-plane can corresponding change diameter size, make chain 9 drive minor sprockets 10 stepless change.Export by chainlet wheel shaft 11 power.When cone 1 was down promoted by top 2, closing spring plate chain tooth bar 7 had not enlarged diameter under the effect progressively on cone inclined-plane, changed with minor sprocket 10 number of teeth ratios, made minor sprocket 10 increase the number of turns of rotation.When cone 1 was up promoted from the step end 4, closing spring plate chain tooth bar 7 had not reduced diameter under the progressively effect on cone inclined-plane, and the number of teeth ratio of minor sprocket 10 is changed, and made minor sprocket 10 reduce the number of turns of rotation.
One of the example of executing of the present invention: " a kind of latch plate chain tooth bar stepless speed changes devices " is used for bicycle gearshift, can realize gear stepless speed changing, and slewing range is wide; Experimental results show that this device can change the speed of sailing of riding arbitrarily; Big and the operation easily of slewing range; Grade ability is strong; Speed-raising is fast; Etc. advantage.
