Description

Technical Field

[0001] The invention relates to the technical field of vehicle hub detection equipment, in particular to a test bench for detecting the wheel hub of a guide rail vehicle. Background Art

[0002] Guideway vehicles are a new type of transportation. Their traction system, motor and brake system all use the most advanced technology in the world today. The vehicles use rubber tires, and their tracks are embedded in the ground. The grooves are inlaid with high-tech rubber pads. When the wheels are running at high speeds, they have little vibration, no noise, and low damage to the road surface. The infrastructure is simple, and general urban roads can be fully utilized to save investment. During the production process of guideway vehicles, it is necessary to test various parts of the vehicle, such as the vehicle wheel hub, to avoid problems in later use and affect the personal safety of users.

[0003] The wheel hub is a cylindrical metal component with the inner contour of the tire supporting the tire and the center mounted on the shaft. It can also be called a wheel rim, steel ring, etc. In the past, most car wheel hub bearings were used in pairs of single-row tapered roller or ball bearings. However, with the development of technology, car wheel hub units have been widely used in cars. The scope and amount of use of wheel hub bearing units are increasing, and they have developed to the third generation: the first generation is composed of double-row angular contact bearings; the second generation has a flange on the outer raceway for fixing the bearings; the third generation wheel hub bearing unit uses a bearing unit in combination with an anti-lock brake system.

[0004] Currently, after the guideway vehicle wheel hub is produced, it is necessary to use a camera to photograph it and perform visual inspection on the photographed photos, so as to determine whether there are scratches or grooves on the outer surface of the guideway vehicle wheel hub, thereby affecting the use of the guideway vehicle wheel hub.

[0005] However, when using a camera to take pictures, the guide rail vehicle wheel hub needs to be fixed first, and then adjusted in direction after taking pictures. When the guide rail vehicle wheel hub is clamped, a clamping surface appears on the outer surface of the guide rail vehicle wheel hub. Therefore, when using the camera to take pictures, the outer surface of the guide rail vehicle wheel hub cannot be photographed, affecting the detection of the outer surface of the guide rail vehicle wheel hub. Summary of the invention
