Abstract
The utility model relates to a combined driving device for a bicycle driven by a bicycler. The combined driving device of the utility model is formed by two-stage gear driving and single-stage chain driving. Medium gears of the utility model are two gears arranged coaxially and side by side. The utility model has the advantages of simple arrangement and compact structure, and enables a bicycler to feel the effect of obvious agility during bicycle riding.
Description
The utility model relates to trackless terrestrial vehicle, is a kind of driving device of wheeled car of rider driving, specifically, is a kind of mechanical device that is used for conveying rotary motion, a kind of gear combination driving device of bicycle.
Now disclosed bicycle drive, be that radially ingear driving gear, mesomerism gear, driven gear are set in the unitized construction of existing crank, chain, flywheel and fastener, with the coaxial sprocket wheel arranged side by side of driven gear, its mesomerism gear is provided with the implied meaning broad of form.
The purpose of this utility model provides a kind of comparatively specific compound transmission of the form that is provided with of mesomerism gear.
The purpose of this utility model can be achieved by following technical proposals: the utility model mesomerism gear is two coaxial gears that are set up in parallel, and it radially connects with driving gear, driven gear engagement respectively, constitutes the two-stage gear transmission.This mesomerism gear can be two gears that the number of teeth is identical, also can be two gears that the number of teeth is different.Certainly, being provided with of this mesomerism gear can also be other suitable versions.
The utility model has the advantages that compared with prior art to be provided with tersely that compact conformation can make bicycle obtain obviously brisk effect in riding.
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the longitudinal construction scheme drawing of an embodiment of the present utility model.
Among the figure 1, driving gear 2, mesomerism gear 3, driven gear 4, coaxial sprocket wheel 5, axis 6, mesomerism gear mandrel 7, driven gear mandrel 8, messenger chain 9, the rear flywheel of driven gear
This is implemented in the illustration, driving gear 1, mesomerism gear 2, driven gear 3, place axis 5 respectively, the coaxial sprocket wheel 4 of mesomerism gear mandrel 6, driven gear mandrel 7, driven gear, by messenger chain 8, connect with rear flywheel 9, the utility model mesomerism gear 2, be two different gears of the number of teeth of being located at mesomerism gear mandrel 6 side by side, it radially connects with driving gear 1, driven gear 3 engagements respectively, constitutes the two-stage gear transmission.
Claims (3)
1, a kind of bicycle compound transmission is by radially order ingear driving gear, mesomerism gear, driven gear, and connect formation with the coaxial sprocket wheel arranged side by side of driven gear, it is characterized in that: the utility model mesomerism gear is two coaxial gears that are set up in parallel, it radially connects with driving gear, driven gear engagement respectively, constitutes the two-stage gear transmission.
2, bicycle compound transmission according to claim 1 is characterized in that: this mesomerism gear is two gears that the number of teeth is identical.
3, bicycle compound transmission according to claim 1 is characterized in that: this mesomerism gear is two gears that the number of teeth is different.
