Description

Technical Field

[0001] The utility model relates to the technical field of vehicle hubs, in particular to a novel vehicle hub. Background Art

[0002] The wheel hub is used to support the tire. In the field of tricycles or low-speed electric scooters (three-wheeled or four-wheeled), the wheel hub mainly includes a rim 1 and a spoke 2, such as Figure 1 As shown, most existing wheel rims have a center section 3, both sides of the center section 3 are connected with abutment sections 4, the ends of the abutment sections 4 are connected with limited position sections 5, the inner diameters of the center section 3, the abutment sections 4 and the limited position sections 5 increase in sequence, wherein the two abutment sections 4 and the outer annular surfaces of the center section 3 jointly form a center inner annular groove 6, the two limited position sections 5 and the outer annular surfaces of the two abutment sections 4 jointly form an assembly outer annular groove 7, and the outer annular surfaces of the spokes 2 are mostly connected to the inner annular surface area of ​​the center section 3, as shown in FIG. Figure 2 As shown, this can save a certain amount of material cost. When in use, the tire is assembled at the outer ring groove 7, and the center inner ring groove 6 can be used to assist the assembly and disassembly of the tire. When the tire is subjected to the force of bumps, the tire pressure will be transmitted to the abutment section 4, and then transmitted to the center end 3 through the abutment section 4, and finally transmitted to the spoke 2 for support. From the aforementioned force transmission path, it can be seen that the abutment section 4 is subjected to a large pressure. Since the spoke 2 is connected to the center section 3, in practice, the wheel hub is very easy to be scrapped due to damage to the abutment section. In addition, since the inner diameter of the center section is small, the area of ​​the spoke connected to it is also small, which not only limits its aesthetic design, but also its support strength for the rim is relatively limited. It can be seen that the existing wheel hub design does not have durability and aesthetics. Utility Model Content
