Description

Technical Field

[0002] A tricycle is a combination of a rickshaw and a bicycle. It can be divided into two categories: a human-powered tricycle and an electric tricycle. Nowadays, most of them are electric tricycles. The wheel hub is the rotating part of the wheel core connected to the inner profile of the tire by a column, that is, the metal part that supports the center of the tire and is mounted on the shaft. It is also called a rim, a steel rim, a wheel, and a tire bell. There are many types of wheel hubs according to their diameter, width, molding method, and material. After their production and processing, they need to be tested for their compressive strength and their own shape specifications to ensure that they can withstand the rated load without deformation, maintain their stable round shape, and perfectly match the tire assembly. The existing detection of the wheel hub is mostly done by applying rated pressure to both sides of the wheel hub through hydraulic equipment and pressure sensors, and then observing whether there are indentations at the pressure position and whether there is overall deformation. It is also necessary to manually adjust the wheel hub position and repeat several sets of pressure application processes to obtain comprehensive pressure measurement data at all parts of the wheel hub. The entire procedure is complicated and has large errors, low accuracy, and is relatively time-consuming. In addition, there are certain safety hazards in the process of pressure application.
