Abstract

The invention discloses a car rim and a spinning process thereof, aiming to overcome defects that existing car rims are heavy, have high driving resistance and are easy to deform due to low strength. The car rim comprises an outer tire bead, an inner tire bead, a bottom groove, an outer rim and an inner rim, wherein the bottom groove is arranged between the inner tire bead and the outer tire bead, the outer rim is connected to the end of the outer tire bead, and the inner rim is connected to the end of the inner tire bead. An outer spinning area and an inner spinning area are respectively arranged on the outer tire bead and the inner tire bead; the outer spinning area extends from the junction of the outer tire bead and the outer rim to the junction of the outer tire bead and the bottom groove, and the inner spinning area extends from the junction of the inner tire bead and the inner rim to the junction of the inner tire bead and the bottom groove. The weight of the rim, the driving resistance and oil consumption are reduced, and the car rim with high strength is not easy to deform. .

Description

[0001] technical field [0002] The present invention relates to an automobile wheel component, and more particularly, to an automobile wheel rim having good strength and light weight. [0003] Background technique [0004] The rim is the carrier of the tire, and its various properties have an important impact on the normal use of the tire and the car. At present, after the general automobile rim is flared, it undergoes one-time molding, two-time molding and three-time molding in sequence, and finally expands and finishes. Through this Five processes basically determine the outline size of the rim. The section thickness of each position of the automobile rim processed by this method is consistent, but the force of each position of the automobile rim in the actual use process is not the same, so the thickness of the rim must meet the maximum force position. strength requirements. If the thickness of the rim is too thick, the thickness of the rim at the less stressed ...
