Description

Technical Field

[0001] The present application relates to the technical field of detection devices, and in particular to a wheel hub strength detection device. Background Art

[0002] To ensure wheel hubs are problem-free during use, automakers require rigorous strength testing. A wheel hub strength testing machine is designed for this purpose, helping automakers test the load-bearing capacity and durability of wheels. The primary function of a wheel hub strength testing machine is to perform load tests on the wheel hub, simulating its use under various conditions. Based on the test data, automakers can determine the wheel hub's load-bearing capacity and durability. To ensure accurate measurements, ensuring the wheel hub is stably secured during testing is crucial.

[0003] The published patent document with the announcement number CN218566912U provides a wheel hub strength detector for vehicle testing, including a main body, a hydraulic strength testing mechanism, and a testing platform. The surface of the testing platform is provided with a wheel hub, the top of the main body is provided with a wheel hub limiting mechanism, the surface of the main body is provided with a dustproof mechanism, and the wheel hub limiting mechanism includes a limiting component, a limiting adjustment component, a guide component, etc.; the utility model can realize the free adjustment of the fixed position of the fixing plate according to the size of the wheel hub through the designed fixing seat, screw hole, screw rod, bearing and hand-cranked wheel, so as to achieve stable limiting of the wheel hub. At the same time, with the designed guide groove and guide rod, it can also guide the fixing plate when it moves. Compared with the existing technology, it greatly facilitates the fixing work of the wheel hub, and can also adjust the fixed position according to the wheel hub belt.

[0004] However, when fixing the wheel hub, the above-mentioned utility model needs to manually rotate the hand wheel to make the fixing plate close to the wheel hub, which is cumbersome and laborious. In addition, this fixing method will clamp and restrict the wheel hub with a larger area and block it, which is not conducive to the uniformity of force and observation when the wheel hub is loaded. In addition, since the installation position of the wheel hub is located directly below the hydraulic strength detection mechanism, the placement of the wheel hub is difficult to operate due to space limitations during installation. Regardless of whether it is lifted manually or by a mechanical structure, the hydraulic strength detection mechanism will interfere with the installation of the wheel hub. Therefore, in response to the above problems, a wheel hub strength detection device is proposed. Utility Model Content
