Abstract
The utility model discloses a kind of Bevel Gear Transmission speed adjusting gear of bicycle, main device includes crank shaft, drive bevel gear group, packaged type transmission shaft, drive axle support, driven wheel of differential group, hind axle, babinet, drive axle support positioning device；Wherein crank shaft with closed assembly is distinguished on hind axle there are two the different bevel gear of diameter, for transmission shaft by two stents loaded on babinet, both ends of the drive shaft is equipped with bevel gear, and the bevel gear of both ends of the drive shaft engages respectively with drive bevel gear group and driven wheel of differential group；For speed governing, transmission shaft can not only rotate, and can also realize displacement by the cooperation of groove on drive axle support and babinet, be moved to different positions, just have different drive bevel gears and driven wheel of differential to be engaged with.The utility model avoids the de- chain of chain drive bicycle, realizes the speed governing of Bevel Gear Transmission bicycle.
Description
Technical field
The utility model is related to a kind of gear drive speed adjusting gears, and in particular to a kind of Bevel Gear Transmission speed governing of bicycle
Mechanism.
Background technology
Currently there are most of bicycle using chain drive, used by long-time, chain easily loosens
It comes off, although attached various chain-drop-proof devices, but can not fundamentally solve the disadvantage that chain drive takes off chain；And
The novel chainless driving pattern bicycle occurred in the market in recent years, mainly using Bevel Gear Transmission, such as in shared bicycle
It rubs and visits bicycle, but can not achieve speed governing, the demand of riding of different user can not be met, many users reflect oneself of Bevel Gear Transmissions
Driving starting is difficult, and ride is laborious.
Invention content
The utility model overcomes above-mentioned drawback existing for chain drive and Bevel Gear Transmission, fundamentally solves chain biography
The shortcomings that dynamic bicycle takes off chain；Drive speed-adjusting mechanism is antifouling dust-proof in babinet, and lubrication is abundant, improves transmission efficiency, reduces
Gear wear, reduces bicycle maintenance cost, extends bicycle service life；The utility model also makes Bevel Gear Transmission
Bicycle realize speed governing, meet the demand of riding of different user.
The technical solution of the utility model is：A kind of Bevel Gear Transmission speed adjusting gear of bicycle, main device include foot
Pedal axis, drive bevel gear group, packaged type transmission shaft, drive axle support, driven wheel of differential group, hind axle, babinet, transmission shaft branch
Frame positioning device.
The crank shaft with closed assembly has the different bevel gear of diameter, the width at two bevel gear intervals respectively on hind axle
Degree is not less than the width of the bevel gear of both ends of the drive shaft, and the coning angle of all bevel gears is identical, about 45 degree.
The packaged type both ends of the drive shaft fills bevel gear, the bevel gear of both ends of the drive shaft respectively with drive bevel gear group and
Driven wheel of differential group engages；For packaged type transmission shaft by bearing and stent loaded on babinet, transmission shaft can not only rotate biography
Graduating power can also realize displacement by the cooperation of groove on drive axle support and babinet.
Babinet vehicle frame as bicycle simultaneously, groove of the babinet equipped with drive axle support slip, in groove
Positioning device equipped with drive axle support.
The drive axle support positioning device is mainly made of babinet, positioning pin, spring；Wherein positioning pin can be on babinet
It moves up and down, under the action of compression spring, the trend of the oriented intermediary movements of positioning pin.

Specific embodiment
Below in conjunction with the accompanying drawings, the utility model is further described below：
Such as attached drawing 1（A）Shown, when transmission shaft 3 is located at upper left side, bevel gear A is engaged with bevel gear C, bevel gear E is with boring tooth
F engagements are taken turns, are driven at this time bigger；Such as attached drawing 1（B）Shown, when transmission shaft 3 is located at lower right, bevel gear B is nibbled with bevel gear C
Conjunction, bevel gear D are engaged with bevel gear F, are driven at this time smaller.
As shown in Figure 2,7 both sides of babinet and upside are equipped with the groove of 4 slip of drive axle support, the transmission shaft on right side
It can be with foot-operated control stick 9 there are one being set above stent 4；Control stick 9 are kicked forward, transmission shaft 3 is moved to lower right,
Referring to attached drawing 1 (B)；Control stick 9 are kicked backward, and transmission shaft 3 is moved to upper left side, referring to attached drawing 1 (A).
As shown in Figure 3, transmission shaft 3 is connect by bearing 10 with drive axle support 4, upper end, the left side of drive axle support 4
End, right end are all in the groove of babinet 7；Transmission shaft 3 can not only rotate passing power, moreover it is possible to pass through 4 He of drive axle support
Displacement is realized in the cooperation of groove on babinet 7.
As shown in Figure 4, drive axle support positioning device 8 is located in the groove of babinet 7, and drive axle support 4 is from a position
It puts during being moved to another position, drive axle support 4 is first up and down pushed positioning pin 11 open, is moved to another
Behind position, positioning pin 11 realizes that positioning steps up under the action of compression spring 12 to drive axle support 4.
As shown in Figure 5, the vehicle frame as bicycle, babinet 7 slide the babinet 7 equipped with drive axle support 4 simultaneously
Groove.
The speed regulation process of mechanism is as follows：Kick control stick 9 forward with foot, drive axle support 4 is along the groove on babinet 7
It slides, transmission shaft 3 is driven to be moved from upper left side toward lower right；Bevel gear A first and bevel gear C, bevel gear E and bevel gear F by
Gradually it is disengaged from；After completely disengaging engagement, the bevel gear C of 3 right end of transmission shaft is between bevel gear A and bevel gear B, transmission shaft
The bevel gear F of 3 left ends is between bevel gear D and bevel gear E；Transmission shaft 3 continues to move toward lower right, bevel gear B and cone tooth
Wheel C, bevel gear D are gradually realized with bevel gear F and are engaged；After transmission shaft is moved to lower right, bevel gear B is engaged with bevel gear C, is bored
Gear D is engaged with bevel gear F, and entire speed regulation process is completed.
