Description

Technical Field

[0001] The utility model relates to the field of tire testing, in particular to a tire blowout testing device. Background Art

[0002] As the only part of a car that contacts the ground, the safety of the tire is crucial to driving safety. If a tire bursts while driving at high speed, it will greatly threaten the life safety of the driver and other road users. Therefore, tire burst testing to ensure its performance and durability under extreme conditions is an important part of automobile manufacturing and tire production.

[0003] A tire blowout is a condition in which the tire body of a pneumatic tire suddenly ruptures and loses the gas in the tire in a very short time (generally about 0.1s). It is an abnormal rapid loss of pressure in a pneumatic tire. A tire blowout is a common driving fault in automobiles. High temperature, speeding, overloading, and improper tire pressure can all cause a tire blowout. After a tire blowout, there will be obvious yaw, even tail swinging, and rapid rotation. Due to the danger of a tire blowout and the different forms, locations, and degrees of tire rupture, there is a lack of unified standards for related experiments, which are still in the theoretical research stage. At this stage, it is difficult to achieve engineering application.

[0004] Existing tire blowout equipment in test sites is also developed based on relevant regulatory requirements for tire blowout testing or related driving training. Most of them take the form of inflation and deflation. This type of test is quite different from a tire blowout in actual driving scenarios. Therefore, a test device is needed to simulate a tire blowout after a high-speed car tire runs over a sharp object. Utility Model Content

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0015] like Figure 1~Figure 2 A tire blowout test device is shown, and a test bench 1 is fixedly buried in a test site. An equipment slot 3 is provided on the upper side of the test bench 1, and a partition wall 2 is provided in the middle of the equipment slot 3. The partition wall 2 divides the equipment slot 3 into two independent slots. Symmetrical module mounting seats 5 are provided on both sides of the partition wall 2. There are four module mounting seats 5, which are respectively used to install sharp nails 71 and simulated stones 72. An installation slot 6 is provided on the upper side of the module mounting seat 5, and a test module 7 is installed in the installation slot 6. The lower part of the test module 7 is tightly matched with the installation slot 6, and the upper end of the test module 7 is higher than the test bench 1. The test module 7 is a physical simulation body, which can simulate sharp nails, stones, sharp cones, etc.

[0016] A support plate 4 is provided in the middle of the equipment slot 3, and a top plate 11 is also provided on the top of the equipment slot 3. The top plate 11 is located on one side of the support plate and covers the equipment slot. The support plate and the top plate 11 are both flush with the ground.
