Abstract
Description
Technical Field
[0001] The present invention relates to the field of automobile parts, and in particular to a new type of two-piece wheel hub Background Art
[0002] Traditional wheels have shortcomings in many aspects such as production, lightweight, and ease of maintenance.
[0003] The one-piece wheel hub is heavy, which is not conducive to vehicle energy saving. Once it is partially damaged, it often needs to be replaced as a whole, which is costly.
[0004] The reliability of the connection parts and the appearance design of the existing two-piece wheels need to be improved, and they cannot meet the growing high performance and aesthetic requirements of the automotive industry. Summary of the invention
[0005] The two-piece hub of the present invention is composed of a rim portion and a spoke portion.
[0006] The rims and spokes are made of high-strength aluminum alloy and are formed through a special forging process.
[0007] A unique reinforcement structure is set at the joint between the rim and the spoke, which is connected with unique high-strength rivets to ensure the connection strength.
[0008] The unique penetration welding technology is then used to better integrate the rim, spokes and rivets to ensure the airtightness of the wheel hub.
[0009] The spokes are designed to be streamlined, which not only reduces weight but also effectively reduces wind resistance. The spokes and rims are connected with hidden rivets, making the hub look more concise and beautiful. In addition, reinforcing ribs are set inside the spokes to enhance the overall structural strength of the hub.
Claims
1. A two-piece hub connection method, characterized in that: include: - A rim and a spoke, wherein a connection hole with a plurality of rivets is provided at the connection portion of the rim, and a through hole matching and corresponding to the connection hole is provided at the connection edge of the spoke.
2. A high-strength rivet, which passes through the through hole of the spoke and the connecting hole of the rim in sequence, and connects the rim and the spoke by penetration welding, and the rivet is interference fit with the connecting hole and the through hole.
