Description

Technical Field

[0001] This utility model relates to the field of tire uniformity testing technology, and in particular to a tire uniformity testing device. Background Technology

[0002] During tire manufacturing, various defects may occur in the tire tread, such as unevenness, cracks, or burns. The quality of the tire tread has a significant impact on the overall quality of the tire, potentially causing vehicle noise and, in severe cases, even posing a risk of tire blowout. During tire manufacturing, the manufacturing process directly affects the tire (including but not limited to material distribution, tread design, and vulcanization uniformity), leading to uneven stress, weight, and material distribution in different parts. This results in different reaction forces at different contact points when the tire surface contacts the road surface. This performance defect is more pronounced when the tire rotates at high speed, leading to a series of serious problems affecting vehicle ride comfort and safety, such as abnormal vibration, lateral sway, noise, and lane deviation. This series of problems is known as the tire uniformity problem. The purpose of this invention is to detect the relevant technical indicators of this problem.

[0003] A tire surface inspection device, disclosed in CN220525667U, includes: a support plate, a rotating component disposed near the center of the upper surface of the support plate, and an adjusting component fixedly connected to the side of the upper surface of the support plate near the rotating component; the rotating component includes a motor, which is fixedly connected to the lower surface of the support plate. In this invention, the tire body is limited by inserting the wheel hub into the gap between the limiting blocks. The tire body is clamped and fixed by the threaded connection between the cover plate and the limiting blocks. The motor drives the rotating shaft, causing the rotating plate to rotate the tire body in front of the image acquisition device. The surface of the tire body can be uniformly illuminated and collected by the image acquisition device, eliminating the need for personnel to constantly monitor the inspection device, thus reducing the workload of the operators.

[0004] The above technical solution cannot fully realize comprehensive tire testing, nor is it convenient for stable tire transportation, so it needs to be improved. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a tire uniformity testing device.
