Aluminum alloy wheel hub with inner wheel flange supported by lantern ring

Abstract

The invention discloses an aluminum alloy wheel hub with an inner wheel flange supported by a lantern ring, and relates to the field of manufacture of aluminum alloy wheel hubs. The aluminum alloy wheel hub is provided with an aluminum alloy wheel hub body, and the supporting lantern ring with elasticity and toughness higher than an aluminum alloy is arranged on the inner side wall of the inner wheel flange of the aluminum alloy wheel hub body, wherein the supporting lantern ring is connected by a liquid glue layer with elasticity after being solidified; the cross section of the supporting lantern ring is L-shaped, and an outward protruding annular locking seat is arranged at the end, located at a rim, of the supporting lantern ring; the outer end of the annular locking seat and the otherend of the supporting lantern ring are in contact with the inner side wall of the inner wheel flange and the inner side wall of the rim, and are tensioned on the inner side wall of the inner wheel flange; a positioning groove matched with the annular locking seat is formed in the inner side wall of the rim, and the width of the positioning groove in the axial direction of the aluminum alloy wheelhub body is greater than the width of the annular locking seat in the axial direction of the aluminum alloy wheel hub body; the positioning groove is a dovetail groove on the side near the inner wheelflange, and the annular locking seat is arranged on the side, away from the inner wheel flange, in the positioning groove in a clamped mode; and the supporting lantern ring is provided with a glue injection hole communicating with the positioning groove, and a sealing cover is arranged on the glue injection hole. In detail, the aluminum alloy wheel hub with the inner wheel flange supported by thelantern ring has high impact resistance and high fatigue resistance at the inner wheel flange, is not prone to cracking at the inner wheel flange, and has high safety.

Description

technical field [0001] The invention relates to the field of manufacturing aluminum alloy wheels, in detail, it is an aluminum alloy wheel hub supported by a collar, which has high impact resistance and fatigue resistance at the inner rim, is not easy to crack at the inner rim, and has high safety. . Background technique [0002] We know that the current aluminum alloy wheel casting technology, no matter low-pressure casting or gravity casting, the wheel shows that the outer rim is supported by spokes, while the inner rim is a completely suspended structure without any support, because the entire rim and inner rim are suspended Yes, during the driving process of the vehicle, the inner rim is frequently subjected to impact deformation, recovery and re-deformation, and this cycle repeats itself, gradually reaching the yield limit of the aluminum alloy material, where plastic deformation occurs, and then tiny cracks that are difficult to identify with the naked eye are formed. ...

AI Technical Summary

Problems solved by technology

At present, most manufacturers adopt measures to increase the thickness of the inner rim and the inner rim, which has two disadvantages: one is that the enhancement effect is not ideal, and there are still market feedbacks and complaints about the deformation or cracking of the rim; the other is to ensure that the casting The sequential solidification conditions must comply with the principle of wall thickness gradient (that is, the closer to the gate, the larger the cross-sectional area is required, and the inner rim and rim are the farthest areas from the gate), and now the inner rim and rim are farthest from the gate. If the part is thicker, it is necessary to increase the casting blank allowance in other parts of the casting, resulting in a substantial increase in the subsequent processing allowance, consuming more manpower, material resources and energy, and also greatly increasing aluminum consumption (the average aluminum consumption in the smelting link ---That is, the evaporated aluminum is about 5%), and the process yield (that is, the percentage of the net weight of the finished wheel and the casting blank) is greatly reduced, which increases the cost of the enterprise
