Abstract
The utility model discloses an automatic gear shifting speed changer which is characterized in that a driving shaft and a driven shaft are respectively provided with more than two groups of bicycle negative direction implements and driven wheels, and the bicycle negative direction implements are connected with the driven wheels by chains or belts. The utility model can realize the automatic gear increasing and reducing through the matching of the bicycle negative direction implements and the driven wheels with throwing wheels, and the utility model has the advantages of vehicle abrasion reduction, oil saving and flexible operation.
Description
Technical field
The utility model relates to the motorcycle accessories technical field, particularly a kind of self-shifting gear box that is applicable to motor bike.
Background technology
The conversion of present motor bike gear is to adopt to do manually operatedly, and its shortcoming is a complicated operation, causes the wearing and tearing of vehicle easily, excessive fuel consumption.
Summary of the invention
The purpose of this utility model provides a kind of self-shifting gear box of speed realization autoshift of energy root a tree name motorcycle driving.
The utility model is to realize like this, it comprises the reverse device of bicycle, follower and chain or belt or gear, follower is got rid of wheel, is provided with in getting rid of the groove of wheel and is used to spur the blade wheel that gets rid of the flexible spring of wheel and be arranged on the outside of getting rid of wheel and forms by the band friction lining in the housing that is arranged on follower, it is characterized in that being connected by chain or belt between reverse device of bicycle and the follower being provided with reverse device of bicycle and follower more than 2 groups on imput shaft and the driven axle respectively.
The utility model is by the cooperation of follower that reverse device of bicycle and band get rid of wheel, can realize increasing automatically the shelves or the purpose of downshift automatically, has the advantage that reduces vehicle abrasion, fuel-efficient and flexible operation.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described;
Fig. 1 is the structural representation of self-shifting gear box;
Fig. 2 is the structural representation of follower.
The specific embodiment
Shown in Fig. 1-2, this self-shifting gear box comprises the reverse device 1 of bicycle, follower 2, chain 3, get rid of wheel 4, friction lining 5, spring 6, blade wheel 7 and shell 8, follower 2 is to take turns 4 by getting rid of of the band friction lining 5 in the shell 8 that is arranged on follower 2, in getting rid of wheel 4 groove, be provided with and be used to spur the work 7 of getting rid of the flexible springs 6 of wheel 4 and being arranged on the outside of getting rid of wheel 4 and take turns composition, on the imput shaft of motor bike and driven axle, be provided with 3 groups of reverse devices 1 of bicycle and follower 2 respectively, be connected by chain 3 between reverse device 1 of bicycle and the follower 2, its principle of work be when motor bike when one grade of speed per hour is travelled, the wheel 4 that gets rid of on reverse device 1 of bicycle on the imput shaft and the follower 2 directly transmits power, when the motor speed of a motor vehicle reaches second grade of startup revolution, getting rid of wheel 4 is thrown away and shell 8 closures, the realization driven axle rotates, driven axle drives other follower 2 and rotates, shell 8 on the follower 2 directly transmits power with the reverse device 1 of bicycle, when the driven axle revolution reaches corresponding revolution, getting rid of wheel 4 is thrown away, shell 8 with get rid of wheel 4 closures, the corresponding quickening of the revolution of driven axle or slow down promptly realizes increasing shelves or downshift.
