Special impact-resistant and rapid-radiating aluminum alloy hub

Abstract

The invention discloses a special impact-resistant and rapid-radiating aluminum alloy hub comprising a hub body. The hub body comprises a hub inner ring and a hub outer ring. The two sides of the hubouter ring are both fixedly connected with the hub inner ring through spokes; a plurality of radiating holes are formed in the surface of the hub outer ring; reinforcing ribs are fixedly arranged on one sides of the spokes; and a plurality of positioning holes are formed in one side of the hub inner ring, and radiating channels are formed in the two ends of one side of the hub inner ring correspondingly. Through the arranged reinforcing ribs, the effect of improving the toughness of the spokes is achieved, and meanwhile the shock resistance effect is achieved properly; through the formed positioning holes, a worker can mount and fix the hub conveniently, and meanwhile detaching is facilitated; during traveling of an automobile, heat is generated between the hub outer ring and a tire because of friction, and the heat can be dissipated effectively and timely through the formed radiating holes; and through arranged heat conducting spacers, heat generated during rotating of the hub inner ring is guided out through the radiating channels.

Description

technical field [0001] The invention relates to a wheel hub, in particular to a special impact-resistant aluminum alloy wheel hub with fast heat dissipation. Background technique [0002] At present, with the development of society, the popularization of automobiles is getting wider and wider, and automobiles are people's main means of transportation, so the safety of automobiles needs to be paid attention to. The main driving tool of the car is the tire, the quality of the tire is directly related to the safety performance of the car, and the hub of the tire plays a vital role. [0003] However, the heat dissipation performance of the existing automobile hub is unstable, resulting in poor heat dissipation effect. During the driving process of the automobile, most of the load needs to be borne. Failure, at the same time there may be the possibility of tire blowout, there is a certain degree of danger, and the current existing wheel hub is easy to cause deformation of the wh...
