Description
Technical field
The utility model relates to a kind of tire, and more particularly, it relates to a kind of wheel hub.
Background technology
Wheel hub, is again wheel rim, wheel, tire bell, be wide support tire in tire drum-shaped, center is contained in the metal parts on axle.Wheel hub is various according to diameter, width, molding mode, material variety classes.
At present, on market, disclosing a kind of application number is the wheel hub with hollow structure and the self-propelled vehicle of CN201320458192.1, comprise wheel rim, multiple spokes and subpanel, spoke one end is fixedly connected with wheel rim, the other end is fixedly connected with subpanel, multiple spokes are distributed between wheel rim and subpanel, on wheel hub, be provided with hollow structure, hollow structure comprises Part I and the interior Part II of spoke body in wheel rim wall, first, two parts are connected, and extend to subpanel place, hollow structure is positioned at the sealing of spoke one end, be positioned at the wheel rim wall other end and be provided with opening, opening is positioned on the internal face of wheel rim, the internal face of wheel rim is used for installing vacuum tire.This utility model also provides a kind of self-propelled vehicle, the wheel hub of what this utility model provided have cavity, and cavity has increased wheel hub dissipating area, has reduced whole wheel hub weight; Cavity communicates with vacuum tire inside, makes cavity identical with vacuum tire internal pressure, and then makes wheel hub have stronger intensity, can not reduce in the situation lower hub safety that reduces wheel hub weight.
Although this utility model adopts hollow structure to improve the heat-sinking capability of wheel hub, due to the existence of expanding with heat and contract with cold, cause its hollow space easily distortion cause that wheel hub structure is unstable, easily damage.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide Stability Analysis of Structures the non-damageable wheel hub with heat sinking function.
For achieving the above object, the utility model provides following technical scheme: a kind of wheel hub, comprise hub body, described hub body comprises bearing hole, spoke and wheel rim, described bearing hole and wheel rim concentric arrange, described spoke two ends connect respectively described bearing hole and wheel rim, and wherein: the junction of described spoke and wheel rim offers the multiple heat radiation through holes with wheel rim axially parallel, described heat radiation through hole is along the uniform setting of inner circumferential of wheel rim.
By adopting technique scheme, described wheel hub is assembled into after tire, described heat radiation through hole can play with a point effect for heat radiation in the time of tyre rotation, and the opening direction of described heat radiation through hole and described wheel rim concentric arrange, described heat radiation through hole forms the supporting structure of spoke around, ensures the stability of described wheel hub.
The utility model is further set to: the junction of described spoke and the wheel rim matcoveredn that is sticked, offers the hollow out just right with louvre team on described protective cover.
By adopting technique scheme, described protective cover can be strengthened the structural strength of spoke and wheel rim junction, further ensures the stability of described wheel hub, and described protective cover can be protected and in the time of operation, play the effect that protection spoke is not collided by foreign matter simultaneously.
This use is novel to be further set to: described protective cover is threaded with hub body.
By adopting technique scheme, described protective cover can facilitate, simple detachable maintaining.
The utility model is further set to: described heat radiation shape of through holes is set to rectangle.
By adopting technique scheme, described rectangular through-hole ensures again when can making dissipating area larger that the junction of spoke and wheel rim has good stability.
