Abstract
The utility model discloses a shockproof and noise reducing motorcycle hub, and belongs to the technical field of motorcycle accessories. The shockproof and noise reducing motorcycle hub comprises a spoke and a rim. The spoke comprises a disk-shaped shaft connecting part and a plurality of spoke parts which are connected with the shaft connecting part and distributed around the shaft connecting part in the circumferential direction, the other end of each spoke part is fixedly connected with the rim through an embedding part embedded into the rim, the center of the shaft connecting part is provided with a bearing bush connected with an axle, and the axial inner side of the shaft connecting part is provided with a brake drum. The brake drum comprises a barrel-shaped drum body, the radial outer surface of the drum body is provided with reinforcing rings, and the cross section of the reinforcing rings is in an L shape. The shockproof and noise reducing motorcycle hub has the advantages that the shock of the wall of the brake drum can be reduced, the noise produced during braking can be effectively reduced, the strength of the brake drum can be enhanced, and the service life of the brake drum can be prolonged.
Description
Technical field
The utility model relates to motorcycle accessories technical field, particularly a kind of shockproof noise-reducing hub of motorcycle.
Background technique
Wheel hub is safety component important in motorcycle driving system, and it acts on motorcycle antero posterior axis, and support tire also rotates with tire.In drum brake system, together with wheel hub is coupled to each other with brake drum, during brake, piston is exerted pressure to two pairs of half-moon-shaped brake shoes, makes it be adjacent to tympanum inwall, thereby produces the rotation that friction stops wheel.The wall thickness of brake drum drum body is generally thinner, the friction of brake shoes and inwall makes thin-walled produce vibrations and sends larger noise, although can reduce vibrations reduction noise by increasing the mode of wall thickness, but increased like this cost of material, and the overall dimensions of brake drum can increase, impact is installed and used.In addition, brake drum is worked under the environment of the High Temperature High Pressure of being everlasting, and its surface easily forms fatigue crack, and along with prolongation and the infiltration of crackle, the mechanical strength of drum body sharply fails, and finally will inevitably cause killing brokenly.
Model utility content
Technical problem to be solved in the utility model is to overcome the problems referred to above, and a kind of shockproof noise-reducing hub of motorcycle is provided, and it can reduce bulging wall vibrations, reduces the noise that brake produces, and extends the working life of brake drum simultaneously.
The technical solution of the utility model is:
Shockproof noise-reducing hub of motorcycle, comprise spoke and wheel rim, described spoke comprises axle joint in the form of annular discs, be connected with axle joint and around its circumferential many uniform spoke portions, the other end of described spoke portion is fixedly connected with wheel rim by the embedding part being embedded in wheel rim, the center of described axle joint is provided with the bearing housing being connected with axletree, the axial inner side of axle joint is provided with brake drum, described brake drum comprises the bulging body of tubular, it is characterized in that: the radially-outer surface of described bulging body is provided with stiffening ring, the transverse section of described stiffening ring is " L " type.
Further, one end of the bulging body of brake drum described in the utility model is opening end, and the other end is drum bottom, and described stiffening ring is arranged on the bulging body radially-outer surface near opening end.
Further, stiffening ring described in the utility model adopts SPHC material to make.
Further, in every spoke portion described in the utility model, all have a vent hole, the radially inner side of described wheel rim is provided with valve hole is set.
Further, in bearing housing described in the utility model, there is the axletree chamber that is positioned at the bearing chamber at two ends and is positioned at middle part.
Further, axle joint described in the utility model, spoke portion and embedding part are structure as a whole.
The beneficial effects of the utility model are: because the outer surface of the bulging body at brake drum is provided with stiffening ring, can reduce bulging wall because of fricative vibrations, thereby effectively reduce brake noise, simultaneously stiffening ring arranges the intensity that has increased brake drum, can reduce the probability that fatigue crack produces, extend its working life.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment's structural representation;
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment
Now by reference to the accompanying drawings and embodiment the utility model is further described:
As depicted in figs. 1 and 2, shockproof noise-reducing hub of motorcycle described in the utility model, comprises spoke 10 and wheel rim 20, and spoke 10 comprises 11,3 spoke portions 12 of axle joint, embedding part 13, the radially inner side of wheel rim 20 is provided with valve hole 21 is set, for valve cock is installed.
Axle joint 11 is in the form of annular discs, and its center is provided with the bearing housing 30 being connected with axletree, has the axletree chamber that is positioned at the bearing chamber at two ends and is positioned at middle part in bearing housing 30.One end of spoke portion 12 is connected with axle joint 11 and is circumferentially uniform around it, the other end is fixedly connected with wheel rim 20 by the embedding part 13 being embedded in wheel rim 20, in every spoke portion 12, all have a vent hole 121, be conducive to alleviate the weight of wheel hub and play thermolysis.Axle joint 11, spoke portion 12 and embedding part 13 are structure as a whole.
The axial inner side of axle joint 11 is provided with brake drum 40, brake drum 40 comprises the bulging body of tubular, one end of drum body is opening end, the other end is drum bottom, bulging body radially-outer surface near opening end is provided with stiffening ring 41, thereby be conducive to reduce bulging wall vibrations, reduce brake noise, increase the intensity of brake drum 40 simultaneously, extend the working life of brake drum.The transverse section of stiffening ring 41 is " L " type, adopts SPHC material to make.
Finally explanation is; above embodiment is only unrestricted in order to the technical solution of the utility model to be described; although the utility model is had been described in detail with reference to preferred embodiment; but those of ordinary skill in the art is to be understood that; can modify or be equal to replacement the technical solution of the utility model; and do not depart from aim and the scope of technical solutions of the utility model, these modifications or be equal to replacement and all should be encompassed among claim protection domain of the present utility model.
