Description

Technical Field

[0001] This utility model relates to the field of vehicle wheel hub technology, and in particular to a split wheel hub that improves the adhesion of electrophoretic paint. Background Technology

[0002] During the production process, wheel hubs require electrophoretic coating. This coating forms a uniform layer of electrophoretic paint on the wheel hub surface, effectively isolating the wheel hub from the external environment and preventing oxidation and corrosion of the metal surface. Existing wheel hubs consist of a rim and spokes. Several bolt seats are welded to the inner circumference of the rim, and the spokes are fixedly connected to the bolt seats by fasteners. The bolt seats have welded plates at both ends. One end face of the welded plate is connected to the bolt seat, and the other three end faces are welded to the inner circumference of the rim, ensuring that each welded plate is attached to the rim. The inner circumference of the wheel rim forms a semi-closed gap. Before electrophoretic coating, the wheel rim undergoes a water blowing process. However, this semi-closed gap can lead to incomplete water blowing. The residual water causes air pockets in the wheel rim during the electrophoresis process, reducing the adhesion of the electrophoretic paint. This results in poor adhesion of the electrophoretic paint inside the semi-closed gap, or even failure to cover the electrophoretic paint. After the wheel rim has been used for a period of time, the poorly adhered electrophoretic paint in the semi-closed gap will peel off. The areas where the electrophoretic paint has peeled off and the parts that are not covered with electrophoretic paint will come into contact with the external environment. After the metal surface oxidizes, yellow water will appear.

[0003] Therefore, a split-type wheel hub is needed to improve the adhesion of electrophoretic paint and solve the above problems. Utility Model Content

[0004] This invention proposes a split-type wheel hub to improve the adhesion of electrophoretic paint. By setting drainage grooves and vent holes on the welding plate, the air is blown into the corresponding semi-enclosed gaps through the vent holes during the water blowing process. The water in the semi-enclosed gaps is discharged from the open end of the semi-enclosed gaps, thereby avoiding the influence of residual water on the adhesion of electrophoretic paint. This allows the electrophoretic paint to fully adhere in the semi-enclosed gaps and prevents the wheel hub from turning yellow after a period of use.

[0005] The technical solution of this utility model is implemented as follows:

[0006] A split-type wheel hub for improving the adhesion of electrophoretic paint includes a rim and spokes. Several bolt seats are welded to the inner circumferential surface of the rim. The spokes are mounted on the bolt seats using fasteners. Each bolt seat includes a connecting plate. The two sides of the connecting plate are bent to form a welding plate. Each welding plate, after being welded to the rim, forms a semi-closed gap with the inner circumferential surface of the rim. At least one drainage groove is provided at the bottom of each welding plate. Each drainage groove contains a vent hole, and each vent hole communicates with the corresponding semi-closed gap.

[0007] As a preferred technical solution, each of the semi-enclosed gaps has an opening at the connection between the corresponding welding plate and the connecting plate.

[0008] As a preferred technical solution, each vent hole is located on the end of the corresponding drainage groove away from the opening.

[0009] As a preferred technical solution, the connection between each drainage groove and the corresponding welding plate is arc-shaped.

[0010] As a preferred technical solution, a plurality of water-blocking protrusions are provided on the inner circumferential surface of the wheel rim, each of the water-blocking protrusions being provided along the axial direction of the wheel rim, and a water-blocking protrusion being provided between the two openings of each bolt seat.

[0011] As a preferred technical solution, the middle position of the bent connecting plate forms a fastener installation space.

[0012] As a preferred technical solution, the fastener includes a plurality of bolts, each bolt passing through a corresponding fastener mounting space.

[0013] As a preferred technical solution, the bolt seats are evenly distributed on the inner circumferential surface of the wheel rim.

[0014] The bolt seats are evenly distributed on the inner circumferential surface of the wheel rim.

[0015] By adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0016] Because the split-type wheel hub, which improves the adhesion of electrophoretic paint, includes a rim, spokes, and bolt seats, and the bolt seats include a connecting plate and welding plates on both sides, after the bolt seats are welded to the rim, the three ends of the welding plates, except for the end connected to the connecting plate, are welded to the rim. Due to the arc shape of the inner circumference of the rim, a semi-closed gap is formed between the welded plates and the rim. By setting drainage grooves and vent holes on the welding plates, air is blown into the corresponding semi-closed gaps through the vent holes during the water blowing process of the wheel hub. The water in the semi-closed gaps is discharged from the open end of the semi-closed gaps, thereby avoiding the influence of residual water on the adhesion of electrophoretic paint. This allows the electrophoretic paint to fully adhere in the semi-closed gaps, preventing the occurrence of yellow water flowing out of the wheel hub after a period of use.

[0017] The existing semi-enclosed gap on the bolt seat has a small internal space, which makes it inconvenient for gas to enter. The setting of the drainage groove increases the internal space of the semi-enclosed gap. During the process of blowing water into the wheel hub, more gas can enter the semi-enclosed gap, thereby blowing the water in the semi-enclosed gap out of the vent hole more quickly and efficiently.

[0018] The water-blocking ridges can block liquid blown out from the open side, preventing liquid from being blown out from one side and then re-entering the semi-enclosed gap on the other side. Attached Figure Description
