Description

Technical Field

The utility model relates to a tire performance test technical field especially relates to a novel all-weather all-round integration tire performance testing research is equipped.

Background

The automobile can safely run on the road depending on the contact between the tire and the ground, and after rainy and snowy weather, when the automobile runs on a wet road surface at high speed, the tire generates a water slip phenomenon due to the dynamic lubrication effect of fluid on the road surface. The hydroplaning phenomenon refers to the phenomenon that when an automobile is fast on a highway with thin-layer accumulated water, the tire cannot directly contact with the road surface to slide due to the action of a water film, and a vehicle body slides to cause difficulty in control of a driver. As the only ground-contacting component of an automobile, the performance of a tire directly affects the performance of the automobile, such as fuel economy, drivability, and safety of the automobile. In the process of developing and manufacturing tires, the performance of the tires needs to be tested, and various design and use performance indexes of the tires are ensured to meet the relevant manufacturing standard and test performance standard requirements of the tires. The performance tests of the tire comprise performance tests such as rolling resistance test, endurance/high-speed performance, inclination angle deflection performance and the like, and the tests are mainly completed on an indoor tire performance test machine. At present, the performance experiment of tires is mostly carried out on an automobile drum experiment table, the drum experiment table adopts a drum to simulate the ground, and the experiment table adopting the drum to simulate the ground is not suitable for the water skid performance experiment because the required space of the drum experiment table is large, the operation is complex, the tire can only be tested integrally, the performance of each rubber material of the tire can not be tested, and excessive waste is caused.

The field experiment mode has some disadvantages: firstly, the disassembly and the assembly of the tested tire are troublesome, and the experiment repeatability is poor; secondly, the required experiment personnel are more, the efficiency is low, the labor intensity is high, and the resource waste is caused; thirdly, the above field test is only to judge the contact between the tire tread and the wet and slippery ground, and cannot measure the tire tread state at different temperatures, and thus has the disadvantage that more detailed and sufficient tests cannot be performed. Therefore, a novel integrated initial performance monitoring and researching device is designed to test the performance of the tire under multiple working conditions.
