[0001] This utility model relates to the field of automotive wheel hubs, specifically a wheel hub that is easy to connect. Background Technology

[0002] The wheel hub is the core component connecting the tire and the axle, and it bears the functions of vehicle weight transfer, steering support and brake heat dissipation. Modern wheel hubs are mostly made of aluminum alloy, which takes into account lightweight, strength and heat dissipation. Some high-end models use forging process or carbon fiber materials to improve performance. Its structure includes three parts: rim (to install the tire), spokes (to support the shape) and disc (to connect the axle).

[0003] In the existing technology, when a car wheel hub is installed onto a vehicle axle using a wheel disc, the small tolerance between the mounting holes on the wheel disc and the studs on the axle makes it difficult to align the car wheel hub with the axle, which reduces the installation efficiency of the wheel hub. Utility Model Content

[0004] To overcome the shortcomings of existing technology, a docking mechanism is used to dock with the stud, and the guide block can guide the stud, which facilitates the installation of the wheel hub onto the axle. This utility model proposes a wheel hub that is easy to dock.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a wheel hub that is easy to connect, including a wheel hub body, an axle mounting part integrally cast in the middle of the wheel hub body, a wheel spoke integrally cast on the outer side of the axle mounting part, the outer end of the wheel spoke is connected to the wheel hub body, an installation groove is provided on the axle mounting part, a wheel hub cover mechanism is snapped and fixed on the installation groove, and a docking hole is provided on the axle mounting part, and a docking mechanism is provided on one side of the docking hole;

[0006] The docking mechanism includes a docking groove formed opposite to the docking hole. A limiting block is integrally formed in the docking groove. A compression spring is welded to one side of the limiting block. A guide block is welded to one end of the compression spring. An arc-shaped support portion is integrally formed on the inner side of the guide block, and an inclined guide portion is integrally formed on the outer side of the guide block.

[0007] Preferably, the spokes are arranged in an arc shape, and the spokes are arranged in a circular array of six groups.

[0008] Preferably, the hub cover mechanism includes a cover body that fits into the mounting groove, and the side of the mounting groove has five sets of hub cover snap-fit ​​grooves arranged in a circular array.

[0009] Preferably, the end of the cover is provided with five sets of sliding grooves arranged in a circular array, and the upper surface of the cover is provided with a clearance groove, which is connected to the sliding groove, and a snap-fit ​​plate is slidably connected in the sliding groove.

[0010] Preferably, a magnet is embedded in the end of the snap-fit ​​plate, and a push-pull portion is integrally formed on the outer side of the snap-fit ​​plate. The push-pull portion is located in the relief groove, and the surface of the push-pull portion is provided with anti-slip texture.

[0011] Preferably, a limiting groove is provided on one side of the guide block, the limiting block is inserted into the limiting groove, and four sets of limiting blocks and guide blocks are arranged in a circular array in each set of docking grooves.

[0013] The advantages of this utility model are:

[0014] 1. This utility model guides the stud during installation through a docking mechanism. Before installation, the guide block slightly contracts inward due to the compression spring. During installation, the guide part on the guide block guides the stud. As the stud is inserted, the spring inside the guide block is compressed under pressure, and the outer wall of the guide block fits against the inner wall of the docking groove. Further insertion into the wheel hub completes the installation. After installation, the stud fits against the arc-shaped support part of the guide block, increasing the actual contact area between the stud, the wheel hub body, and the docking mechanism, thus ensuring the stability of the vehicle during driving after the wheel hub is installed.

[0015] 2. This utility model uses a hub cover mechanism to shield the outside of the docking mechanism. The hub cover mechanism uses a snap-fit ​​plate slidably connected at the end of the cover body to snap-fit ​​the hub cover snap-fit ​​groove in the mounting groove on the hub body. After installation, it can prevent external substances from entering and corroding or jamming the bolts in rainy or windy weather. At the same time, when the car is moving, the snap-fit ​​plate will engage with the hub cover snap-fit ​​groove due to centrifugal force, and it will not fall off even at high speed. When disassembling, you only need to use five fingers to push and pull the snap-fit ​​plate inward and pull the cover outward to separate it. It is easy to disassemble and assemble.
