Change-gear set is one group, comprises one bonded assembly canine tooth wheel disc and miniature gears dish, and wherein the miniature gears dish is connected with sprocket wheel by chain, and the canine tooth wheel disc is connected with flywheel by chain.
Can also reach the purpose of this utility model by following measure:
The change-gear set branch comprises first stud gear group and second stud gear group, first stud gear group and second stud gear group are made of one bonded assembly canine tooth wheel disc and miniature gears dish respectively, wherein the miniature gears dish of first stud gear group is connected with sprocket wheel by chain, the canine tooth wheel disc of first stud gear group is connected with the miniature gears dish of second stud gear group by chain, and the canine tooth wheel disc of second stud gear group is connected with flywheel by chain.
The first stud gear group is fixed in by rotating shaft on the strut bar of the vehicle frame that connects sprocket wheel and cushion, and is triangular in shape with sprocket wheel and second stud gear group.
Technique effect of the present utility model is: reach the revolution ratio that increases trailing wheel and sprocket wheel by increasing by one group or two groups of change-gear sets, can increase work efficiency.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment 1.
Fig. 2 is the structural representation of the utility model embodiment 2.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1, this multiple sets of teeth wheel variable speed bicycle, identical with existing bicycle, comprise vehicle frame 1, front-wheel 2, trailing wheel 3 and drive system 4, certainly also comprise headstock, seat cushion and brake system etc., drive system 4 comprise too be fixed on vehicle frame 1 lower end sprocket wheel 5, with trailing wheel 3 coaxial bonded assembly flywheel 6 and chains 8, institute's difference is: drive system 4 also comprises the change-gear set 7 that is positioned at 6 on sprocket wheel 5 and flywheel, and sprocket wheel 5, change-gear set 7,6 on flywheel use chain 8,8 ' to connect transmission successively.Be used to increase the revolution ratio of flywheel 6 and sprocket wheel 5.
The change-gear set 7 of present embodiment is one group, comprise one bonded assembly canine tooth wheel disc 9 and miniature gears dish 10, be installed in by rotating shaft on the cross bar 11 of vehicle frame 1 of 6 on sprocket wheel 5 and flywheel, wherein miniature gears dish 10 is connected with sprocket wheel 5 by chain 8, and canine tooth wheel disc 9 passes through chain 8 ' and is connected with flywheel 6.Foot-operated when stepping on, when crank drives sprocket wheel 5 rotations, sprocket wheel 5 drives change-gear set 7 successively, flywheel 6 rotates, if sprocket wheel 5 is R1 with the diameter ratio of the miniature gears dish 10 of change-gear set 7, the canine tooth wheel disc 9 of change-gear set 7 is R2 with the diameter of flywheel 6 ratio, then when 5 one weeks of rotation of sprocket wheel, flywheel will rotate R1*R2 week.Generally, the ratio of R1 and R2 is between the 2-4, and the ratio of R1 and R2 is 4 in the present embodiment, so when 1 week of sprocket rotation, flywheel will rotate for 16 weeks.
Present embodiment is different from embodiment 1 part and is: change-gear set 4 comprises first stud gear group 12 and second stud gear group 13, first stud gear group 12 and second stud gear group 13 are respectively by one bonded assembly canine tooth wheel disc 14,14 ' and miniature gears dish 15,15 ' constitutes, wherein the miniature gears dish 15 of first stud gear group 12 is connected with sprocket wheel 5 by chain 8, the canine tooth wheel disc 14 of first stud gear group 12 is by chain 8 ' ' be connected with the miniature gears dish 15 ' of second stud gear group 13, the canine tooth wheel disc 14 ' of second stud gear group 13 is connected with flywheel 6 by chain 8 '.Consider the structure of bicycle itself, present embodiment is fixed in first stud gear group 12 on the strut bar 16 of the vehicle frame that connects sprocket wheel and cushion by rotating shaft, first stud gear group 12 and sprocket wheel 5 and 13 settings triangular in shape of second stud gear group.If sprocket wheel 5 is S1 with the diameter ratio of the miniature gears dish 15 of first stud gear group 12, the canine tooth wheel disc 14 of first stud gear group 12 is S2 with the diameter ratio of the miniature gears dish 15 ' of second stud gear group 13, the canine tooth wheel disc 14 ' of second stud gear group 13 is S3 with the diameter of flywheel 6 ratio, can learn, then when one week of sprocket rotation, flywheel will rotate S1*S2*S3 week, and the ratio of S1, S2, S3 is respectively 4,4,2 in the present embodiment, so when 1 week of sprocket rotation, flywheel will rotate for 32 weeks.
