Description
Technical field
The utility model relates to a kind of motorcycle unilateral side rear arms.
Background technique
The patent that Chinese invention patent authorized application number is 201621398902.6 disclose a kind of motorcycle it is unilateral after shake
Arm, including rear arm ontology, rear arm ontology are integral, including rear shock absorber inserting hole, rear mudguard installation point, damper
It is driven installation point and rear-wheel disc brake installation point, wherein the rear shock absorber jack for interting rear shock absorber is set and rear arm ontology
One end and in semi-circular, the arc-shaped side of the inserting hole is equipped with rear mudguard mounting hole, the lower section of rear mudguard mounting hole
And the inner side for being located at rear arm ontology is equipped with damper and is driven mounting hole, rear-wheel disc brake installation point is set to rear arm ontology
The position of other end inner wall and corresponding disc brake.
In above structure, due to road bump during motorcycle driving, rear arm ontology subtracts after the power of fluctuating is passed through
The transmission device of shake is transmitted to rear damping, and rear damping interts movement from the present apparatus, while chain passes during motorcycle driving
When dynamic, surface relief can fluctuate up and down, and chain can be made to become more not enough to be tensioned, and influence the efficiency of transmission, or even chain can be made to fall
It falls.
It is outstanding that the patent that Chinese invention patent authorized application number is 201720171311.3 discloses a kind of motor cycle rear wheel list
Assembly, including at least one list rocker arm are hung, single rocker arm forms rear-wheel receiving portion to curving, and single one end is connected with first
Mounting cylinder, there are two the second mounting cylinders for single rocker arm other end connection；It further include being located at ipsilateral rear-wheel with rear-wheel receiving portion to install
Disk, rear-wheel mounting disc are equipped with the main shaft extended into the first mounting cylinder, and main shaft free end is bolted with sprocket wheel chain wheel.After further including
Wheel cylinder bracket and the eccentric spindle nose being flexibly connected with rear wheel cylinder bracket, eccentric spindle nose are set on the first mounting cylinder by main shaft
It is interior.Such structure in use due to be not be integrally formed its intensity it is not high, cause single rocker arm be easy to appear slight crack influence row
The safety of vehicle, while the structure does not have the tensioning of the chain structure yet, causes the elastic of chain to be difficult to control, influences the effect of transmission
Rate.
Summary of the invention
To solve the above problems, and a kind of chain reliable the purpose of this utility model is to provide structure is elastic adjustable
Motorcycle unilateral side rear arm.
To achieve the above object, the utility model provides following technical solution: a kind of motorcycle unilateral side rear arm, including
Integrally formed rocker arm ontology is equipped with mounting hole in one end of the rocker arm ontology, and the section of the rocker arm ontology is in a ring
Enclosed construction is equipped with the eccentric hub rotatably adjusted in the mounting hole, has eccentric orfice on the eccentric hub, described
Eccentric orfice in be equipped with shaft, the shaft is connect by bearing with the eccentric orfice, and the shaft side is connected with
Chain chain wheel, the shaft other side are connected with brake disc.
It is equipped with the defining flange of circular ring shape in described eccentric hub one end, is pressed in the defining flange outer circumferential walls certain
Spaced apart circumferential is arranged with several and stirs groove.
It is socketed with wheel hub in the shaft between the brake disc and the adjoining end of the shaft, at described turn
Axis is equipped with fixing sleeve corresponding with the wheel hub, and the side in the fixing sleeve towards wheel hub direction is equipped with the conical surface, at described turn
Shaft end portion is bolted with locking nut, which, which screws, presses on the end face of the fixing sleeve.
This structure of the utility model, by stir on defining flange stir groove can make eccentric hub along mounting hole turn
It is dynamic, and then the position of shaft is made to shift, shaft drives the position of chain chain wheel to be deviated, and chain thus may be implemented
Tensioning adjustment, and the enclosed construction of the section of rocker arm ontology in a ring makes the structural strength more preferable, effectively improves driving
Safety and vehicle durability.
The utility model is further described with reference to the accompanying drawings and detailed description.
Detailed description of the invention
Fig. 1 is the perspective view of specific embodiment of the present invention；
Fig. 2 is the side view of specific embodiment of the present invention；
Fig. 3 is the cross-sectional view of B-B in Fig. 2；
Fig. 4 is the cross-sectional view of C-C in Fig. 2；
Fig. 5 is the cross-sectional view of A-A in Fig. 2.
Specific embodiment
The utility model is specifically described below by embodiment.
As Figure 1-Figure 5, present embodiment discloses a kind of motorcycle unilateral side rear arms, including integrally formed rocker arm sheet
Body 1 is equipped with mounting hole 12 in one end of rocker arm ontology 1, and rocker arm ontology 1 adds the casting technique of metal mold using sand mold, so that shaking
The enclosed construction of the section of arm body 1 in a ring, as shown in figure 4, the section of rocker arm ontology 1 enclosed construction in a ring, is equivalent to
There is cavity in rocker arm ontology 1, the eccentric hub 2 rotatably adjusted is equipped in mounting hole 12, there is eccentric orfice on eccentric hub 2
21, eccentric orfice 21 is interior to be equipped with shaft 3, and shaft 3 is connect by bearing 4 with eccentric orfice 21, and 3 side of shaft is connected with chain chain wheel 5,
3 other side of shaft is connected with brake disc 6.
It is equipped with the defining flange 22 of circular ring shape in eccentric 2 one end of hub, is justified at regular intervals in 22 outer circumferential walls of defining flange
It is arranged with several week and stirs groove 221.
It is socketed with wheel hub (not shown) in shaft 3 between brake disc 6 and the adjoining end of shaft 3, in shaft 3
It is equipped with fixing sleeve 7 corresponding with wheel hub, the side in the fixing sleeve 7 towards wheel hub direction is equipped with the conical surface, in 3 end spiral shell of shaft
It is connected to locking nut 8, which, which screws, presses on the end face of fixing sleeve 7.Such structure can make the installation of wheel hub more
Add reliable convenience.
In conclusion by stir on defining flange 22 stir groove 221 can make eccentric hub 2 along mounting hole 12 rotate,
And then the position of shaft 3 is made to shift, shaft 3 drives the position of chain chain wheel 5 to be deviated, and chain thus may be implemented
Tensioning adjustment, and the enclosed construction of the section of rocker arm ontology 1 in a ring effectively improves row so that the structural strength is more preferable
The safety of vehicle and the durability of vehicle.
