The utility model content
Technical problem to be solved in the utility model is, be equipped with on the motor bike of step change transmission, solve with foot's gear shift difficulty or inconvenient technical matters, can solve the problems of the technologies described above and provide a kind of, and motorcycle shift mechanism simple in structure, easy disassembly.
The technical scheme that the utility model adopted is, a kind of motorcycle shift mechanism, comprise, hand-control device, foot-propelled gear-shift lever, power supply, with power supply by lead bonded assembly actuating device and with actuating device bonded assembly driving device, described actuating device is provided with worm screw, driving device is provided with the worm gear and the eccentric cam of deceleration, and described worm screw links to each other with eccentric cam with the worm gear of deceleration.
Described actuating device comprises rotor, stator, carbon brush, commutator and is installed in worm screw on the stator that described actuating device is installed on the change-speed box of motor bike.
Described rotor is arranged in the described stator, by carbon brush and commutator outputting power, the worm screw that is installed on the described stator is rotated.
Described driving device comprise a deceleration worm gear, eccentric cam, connecting rod and with the limit spring that is provided with at interlinking lever end.
The worm gear of described deceleration and worm mesh.
Described worm gear is that rigidity is connected with described eccentric cam, and described eccentric cam contacts with described interlinking lever end.Connecting rod in the described driving device and described foot-propelled gear-shift lever are by the detouchable bolted connection.
Adopt technical scheme provided by the utility model, can effectively solve on the motor bike of step change transmission, foot's gear shift difficulty or inconvenient technical matters, compared with prior art, owing to adopt Electronmotive Force, only need to give shift signal of chaufeur, just can realize gear shift, and, technical scheme provided by the utility model also has simple in structure, dismantles easily and installs, and is easy to use, operation is reliable, characteristics such as the low and long service life of cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Wherein, 1 is the foot-propelled gear-shift lever; 2 is connecting rod; 3 is limit spring; 4 is worm gear; 5 is eccentric cam; 6 is worm screw; 7 is carbon brush; 8 is commutator; 9 is rotor; 10 is stator; 11 is limit switch.
The specific embodiment
As shown in Figure 1, a kind of motorcycle shift mechanism, comprise, hand-control device, foot-propelled gear-shift lever 1, power supply, with power supply by lead bonded assembly actuating device and with actuating device bonded assembly driving device, described actuating device is provided with worm screw 6, driving device is provided with the worm gear 4 and the eccentric cam 5 of deceleration, and described worm screw 6 links to each other with eccentric cam 5 with the worm gear 4 that slows down.Described actuating device comprises rotor 9, stator 10, carbon brush 7, commutator 8 and is installed in worm screw 6 on the stator 10 that described actuating device is installed on the change-speed box of motor bike.Described rotor 9 is arranged in the described stator 10, by carbon brush 7 and commutator 8 outputting powers, the worm screw 6 that is installed on the described stator 10 is rotated.Described driving device comprise a deceleration worm gear 4, eccentric cam 5, connecting rod 2 and with the limit spring 3 that is provided with in connecting rod 2 ends.The worm gear 4 of described deceleration and worm screw 6 engagements.Described worm gear 4 and described eccentric cam 5 are for rigidity is connected, and described eccentric cam 5 contacts with described connecting rod 2 ends.Connecting rod 2 in the described driving device passes through the detouchable bolted connection with described foot-propelled gear-shift lever 1.Described limit switch 11 is fixed on cam and complains to the higher authorities about an injustice and request fair settlement.
The technical scheme that the utility model adopted, working process is as follows:
The technical scheme that the utility model adopted by hand-control device, will make rotor 9 in stator 10 inner rotations from the current lead-through of power supply, and the rotation of rotor 9 drives the worm screw 6 that is arranged on rotor 9 ends and rotates; Because therefore worm screw 6 and worm gear 4 engagements with deceleration effort drive worm gear 4 and rotate; Worm gear 4 is connected (being generally welding) with eccentric cam 5 for fixing rigidity, and therefore, eccentric cam 5 begins to rotate; Eccentric cam 5 is that contact is connected with end connecting rod 2, and therefore, under the effect of eccentric cam 5 top power, connecting rod 2 is subjected to displacement; Connecting rod 2 passes through bolted connection with the foot-propelled gear-shift lever 1 of motor bike, and under the drive of connecting rod 2, foot-propelled gear-shift lever 1 is changed the beginning gear again.After gear changed out, cam stopped under the effect of limit switch.
The utility model mainly is at motor bike, and characteristics are by rotor, stator and speed reduction gearing, can adopt button manually to control motor bike advance and retreat shelves with hand-control device, is mainly used in two-wheeled, three-wheel and four-wheel motor cycle.
It is more convenient and set that the utility model mainly is convenient to drive two-wheeled, three-wheel and four-wheel motor cycle gear shift to steerman.
The utility model is finished in the following manner, drive the worm gear 4 that slows down with 12 volts of DC machine of button relay control by worm screw 6, it is slowly run, pass through eccentric cam 5 drive link 2 of reducing gear center shaft again, connecting rod 2 and foot-propelled gearshift connect, and reach the purpose of own gear shift on the fixing motorcycle-gear case again of entire mechanism.
Adopt technical scheme provided by the utility model, can effectively solve the motorcycle at step change transmission On, foot's gear shift difficulty or inconvenient technical problem, compared with prior art, owing to adopt electric power, only Need to shift signal of driver, just can realize gear shift, and, technology provided by the utility model Scheme also has simple in structure, dismantles easily and installs, and is easy to use, and operation is reliable, the low and use of cost The characteristics such as the life-span is long.
