Description

Technical Field

[0001] This utility model relates to the field of wheel hub technology, specifically a high-strength wheel hub. Background Technology

[0002] With the rapid development of the automotive industry, the performance requirements for vehicle wheel hubs are increasing, especially in terms of strength and stability. As a key component of automobiles, wheel hubs not only need to withstand various complex forces from the road surface during vehicle operation, but also need to have good stress dispersion capabilities to prevent damage caused by local stress concentration, thereby ensuring driving safety.

[0003] Traditional wheel hub designs often employ simple structural connection methods, such as direct bolt connections or welding. While these methods can meet basic strength requirements, they are prone to problems such as loosening of connection points and stress concentration when dealing with complex working conditions. This leads to a decrease in the overall strength of the wheel hub, affecting the stability and safety of the vehicle.

[0004] To address the aforementioned issues, some improved wheel hub designs have emerged in the prior art. For example, a high-strength wheel hub proposed in a Chinese patent (patent publication number CN218367233U) enhances the strength of the wheel hub by optimizing its structure and employing a specific reinforcing rib design. However, this patent only addresses the issue of enhancing the local strength of the wheel hub through reinforcing ribs, without fully considering the precise positioning and connection stability between the various components of the wheel hub, as well as the construction of the overall stress distribution system. In actual use, if there is relative displacement or rotation between the various components of the wheel hub, it will seriously affect the overall performance of the wheel hub, leading to uneven stress distribution and even causing safety accidents.

[0005] To address these issues, we have proposed a high-strength wheel hub. Utility Model Content

[0006] To address the shortcomings of existing technologies, this invention provides a high-strength wheel hub that solves the aforementioned problems.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution: a high-strength wheel hub, comprising a hub body, an inner ring body for mounting is provided on the inner side of the hub body, and a plurality of connecting rods for connection are evenly installed between the hub body and the inner ring body, and further comprising:

[0008] A positioning component, installed at the center of the connecting rod, is a structure used for positioning the connecting rod during installation.

[0009] Preferably, the connecting rod structure is S-shaped, with threaded holes for fixing installed on both ends of the connecting rod, and a positioning hole for positioning installed at the center of the connecting rod.

[0010] Preferably, the upper half of the inner ring body has a plurality of mounting grooves that match the connecting rod. One end of the connecting rod is installed inside the mounting groove. An internal fixing bolt for fixing is installed on the upper surface of the inner ring body at the position corresponding to the mounting groove. The lower end of the internal fixing bolt passes through the surface of the connecting rod and is connected to the inner ring body.

[0011] Preferably, the inner surface of the wheel hub body is provided with a plurality of snap-fit ​​grooves that match the connecting rod, the other end of the connecting rod is installed inside the snap-fit ​​groove, and an external fixing bolt is provided on the upper surface of the wheel hub body corresponding to the position of the snap-fit ​​groove, the lower end of the external fixing bolt passing through the surface of the snap-fit ​​groove and connecting to the wheel hub body.

[0012] Preferably, the positioning component includes a fixing block, a positioning pin, and a connecting cover plate. A fixing block for fixing is installed between the two connecting rods. A positioning pin for positioning is provided on the outer side of the fixing block. One end of the positioning pin passes through the fixing block and is connected to the connecting rod. Connecting cover plates for connection are installed at the upper and lower ends of the plurality of fixing blocks.

[0013] Preferably, a plurality of the fixing blocks are installed at the center of the connecting rod, and the fixing blocks are arranged in a close fit with the connecting rod.

[0014] Preferably, the surfaces of the fixing block and the connecting cover plate are provided with a plurality of threaded holes for installation, the threaded holes are fitted with connecting bolts for fixing, and the connection between the connecting bolts and the connecting cover plate is fitted with a buffer pad for cushioning.

[0015] Compared with the prior art, the present invention provides a high-strength wheel hub with the following advantages:

[0016] 1. This high-strength wheel hub features a locating pin inserted into the center locating hole of the connecting rod. This precisely positions the fixing block and the connecting rod, preventing the connecting rod from shifting or rotating within the fixing block. This ensures the accurate positioning of all components of the wheel hub structure under stress, improving overall stability. The locating pin not only precisely positions the connecting rod but also facilitates its installation. Installers can quickly and accurately install the connecting rod using the locating pin. The S-shaped connecting rod, fixing block, connecting cover, and other components work together to create an efficient stress dispersion system on the wheel hub's composite surface. When the vehicle is under stress, the external force is evenly distributed to all parts of the wheel hub, avoiding localized stress concentration on the composite surface and effectively improving the overall strength of the composite surface.

[0017] 2. This high-strength wheel hub uses an S-shaped connecting rod to engage with the mounting groove of the inner ring body and the snap-fit ​​groove of the wheel hub body at both ends, and is then secured with inner and outer fixing bolts to achieve a stable connection between the wheel hub body and the inner ring body. This effectively withstands various complex forces from the road surface during vehicle operation, ensuring that the wheel hub will not experience problems such as component separation during operation. Buffer pads are placed at the connection between the connecting bolts and the connecting cover plate, which can effectively buffer the vibration and impact generated during vehicle operation and prevent the connecting bolts from loosening due to vibration.
