Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

Fig. 1 is a schematic structural diagram of an outer end cover of a wheel provided in this embodiment, and in conjunction with fig. 1, an embodiment of this application provides an outer end cover of a wheel, which is generally mounted on a wheel to perform a sealing function. The outer end cover of the wheel comprises a body 100 and a plurality of heat dissipation ribs 200, wherein the body 100 is assembled on the wheel, and the end face of the body 100, which is far away from the wheel, is a heat dissipation surface; the plurality of heat dissipation ribs 200 are disposed on the heat dissipation surface of the body 100, and the plurality of heat dissipation ribs 200 are arranged in a circumferential direction of the heat dissipation surface to form a "cyclone" structure together. Therefore, the plurality of rotating heat dissipating ribs 200 force the air to be convected and ventilated. When the body 100 rotates along with the wheel, air on the upper portion of the outer end cover of the wheel is stressed and flows away to generate negative pressure, air on the lower portion flows into the upper portion area, and therefore air flowing is formed, heat generated in the running process of the discharging mechanism is discharged, the cooling and radiating effects are good, and damage to parts inside the wheel due to high temperature is avoided.

Preferably, the heat dissipating ribs 200 are streamlined, thereby avoiding unnecessary friction loss and kinetic energy, and reducing noise

In the related art, the outer end cover of the wheel is generally a thin-wall iron casting, which is easy to have casting defects such as shrinkage cavities, sand holes and the like, and causes oil leakage at the wheel rim, therefore, the outer end cover of the wheel in the embodiment adopts an aluminum forging, which can effectively eliminate or reduce the oil leakage at the wheel rim, and has a lighter weight than the iron casting by about 2/3, thereby achieving the effect of reducing the weight of the whole machine. And meanwhile, the oxidation layer is arranged on the heat dissipation surface, namely, in the specific implementation process, the heat dissipation surface is subjected to anodic oxidation treatment, and compared with painting on an iron casting in the related technology, the anticorrosion effect and the surface quality after the oxidation layer is arranged on the aluminum forging piece are obviously improved.

In some embodiments, at least a portion of the heat dissipating surface is convex, and the plurality of heat dissipating ribs 200 are disposed on the convex surface. Further, a mounting portion 120 is provided at the center of the heat dissipating surface to mount a decoration or other functional member, and preferably, the mounting portion 120 is circular. The convex surface sets up between the edge of installation department 120 and cooling surface, and it is obvious that installation department 120 is for the concave surface 110 of relative convex surface, and level and smooth and easy connection between concave surface 110 and the convex surface, cooling surface adopt the concave and convex surface to combine together promptly, compares the plane, and heat radiating area is bigger, can promote the radiating effect.
