Description

Technical Field

[0001] This utility model belongs to the field of tire technology, specifically relating to a tire performance testing device in wet conditions. Background Technology

[0002] Tires are annular, elastic rubber products that are mounted on various vehicles or machinery and roll on the ground. They are typically mounted on metal rims, supporting the vehicle body, cushioning external impacts, ensuring contact with the road surface, and guaranteeing vehicle performance. Tires are often used under complex and harsh conditions, enduring various deformations, loads, forces, and extreme temperatures during operation. Therefore, they must possess high load-bearing capacity, traction, and cushioning performance. Simultaneously, they are required to have high wear resistance and flexural strength, as well as low rolling resistance and heat generation.

[0003] The utility model patent with authorization announcement number "CN218330914U" describes "a tire performance testing device, including a testing platform. The top of the testing platform has several grooves, through which a grinding plate slides. Several springs are fixedly connected to the bottom of the grinding plate. A sliding plate is fixedly connected to the end of the spring away from the grinding plate. A first hydraulic rod is fixedly connected to the bottom of the sliding plate. The first hydraulic rod is fixedly connected to the bottom of the groove. Small grooves are formed on both sides of the groove. Small rods are fixedly connected to both sides of the grinding plate and slide in the small grooves. This utility model has the following advantages: By adjusting the length of the output end of the first hydraulic rod, the spring is squeezed by the sliding plate, and the length of the spring changes. This changes the elastic coefficient of the spring, thereby providing different amounts of elastic force to the tire on the grinding plate, thus simulating the wear resistance test of tires of vehicles with different loads. This makes the tire wear resistance test data more comprehensive."

[0004] The aforementioned patents can make tire wear performance test data more comprehensive. However, in the existing technology, after testing the tire, it is necessary to place the tire at the test site, which makes the loading and unloading process more troublesome and thus affects the testing efficiency.
