Technical Field

[0001] This invention relates to the field of aviation tire testing equipment technology, and in particular to a tire high-acceleration test injection temperature measurement device and method. Background Technology

[0002] To ensure the safety of aircraft tires during use, they need to simulate the complex stress environment under extreme conditions such as catapult takeoff, ski-jump takeoff, carrier landing, roll, yaw, and aborted takeoff. Therefore, during the research and development and production process, aircraft tires need to undergo high load, high acceleration tire dynamic characteristic tests, tire wear performance tests, tire braking tests, and other tire characteristic tests.

[0003] Currently, the key challenge in the testing technology of high-load and high-acceleration aircraft tires in China is the provision of testing methods for the research of new synthetic rubber materials and other natural rubber tire characteristics, filling the gap in domestic high-acceleration tire testing technology. The applicant has conducted relevant research and development on this technology to strengthen the shortcomings of domestic aircraft tire performance evaluation methods.

[0004] During the high-load and high-acceleration testing of aircraft tires, it is necessary to obtain a series of parameter changes such as tire temperature during the test in order to evaluate the overall performance of the tire. Currently, conventional temperature measurement devices cannot meet the requirements of high-acceleration tire testing, and a solution is urgently needed. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a tire high-acceleration test injection temperature measurement device and method, in which a temperature measuring needle is inserted into the interior of the tire under test from the surface of the tire. The temperature measuring needle collects the temperature at the test location of the tire, which facilitates tire performance testing to meet the requirements of high-acceleration tire testing.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] The present invention provides a tire high-acceleration test injection temperature measurement device, including a mounting frame, an injection mechanism disposed on the mounting frame, and a temperature measurement driving device for driving the mounting frame to move the injection mechanism closer to or further away from the tire being tested.

[0008] The injection mechanism includes a temperature measuring needle and an injection drive mechanism for driving the temperature measuring needle to move.

[0009] The injection mechanism further includes an injection mounting base mounted on the mounting frame, and the injection drive mechanism is mounted on the injection mounting base;

[0010] The injection drive mechanism is provided with an adjusting cylinder with external threads. At least two adjusting components are threadedly connected to the adjusting cylinder, and the two adjusting components lock the adjusting cylinder to the injection mounting seat.

[0011] The injection mechanism is further provided with a limiting cylinder with external threads and a limiting member threadedly connected to the limiting cylinder. The limiting cylinder is provided with a limiting groove, and a limiting pin is movably provided in the limiting groove. The limiting pin is located outside the limiting member. The injection driving mechanism is further provided with an execution driving rod. One end of the execution driving rod extends into the limiting cylinder and is connected to the limiting pin. The temperature measuring needle is driven to the other end of the execution driving rod.

[0012] The injection drive mechanism is connected to a cylinder for protecting the temperature measuring needle. When the temperature measuring needle is not injecting and measuring the temperature of the tire being tested, the temperature measuring needle is located in the cylinder.

[0013] Preferably, the injection drive mechanism is a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder.

[0014] The injection mechanism is provided in multiple ways; the multiple injection mechanisms are used to inject and measure the temperature of the tire tread, tire shoulder and tire sidewall.

[0015] The mounting frame is provided with a accommodating space for accommodating the tire under test; two injection mechanisms are provided for injecting and measuring the temperature of the tire shoulder and sidewall under test, and the two injection mechanisms are distributed on both sides of the accommodating space.

[0016] The mounting frame is provided with two symmetrically arranged mounting parts, and each mounting part is provided with a connecting part, a tire shoulder detection mounting part connected to the connecting part, and a tire sidewall detection mounting part connected to the tire shoulder detection mounting part;

[0017] The injection mechanism is installed on both the tire shoulder detection mounting part and the tire sidewall detection mounting part, and the injection mechanism is installed between the two connecting parts; the two mounting parts and the injection mechanism between the two connecting parts form the accommodating space.

[0018] The mounting frame is further provided with a width adjustment component connected to the connecting part, a width adjustment mounting component, a height adjustment mounting component connected to the width adjustment mounting component, and a movable frame;

[0019] The width between the two mounting components is adjusted by adjusting the installation positions of the width adjusting component and the width adjusting mounting component; the height of the injection mechanism is adjusted by adjusting the installation positions of the height adjusting mounting component and the movable frame; the movable frame is driven by the temperature measuring drive device.

[0020] The movable frame is connected to a guide member, and the guide member is slidably connected to a guide seat, which is used to connect to the test bench frame.

[0021] This invention also provides a method for measuring tire temperature by injection during high-acceleration testing, comprising the following steps:

[0022] S01: Install a needle temperature measuring device on one side of the loading head of the tire being tested on the test bench;

[0023] S02: During the tire performance test, the temperature measuring drive device of the injection temperature measuring device drives the mounting frame with the injection mechanism to approach the tire under test; and makes the tire under test located in the accommodating space of the mounting frame with multiple injection mechanisms around it.

[0024] S03: At the tread, both sides of the tire shoulder and the sidewall of the tire being tested, the temperature measuring needle of the injection mechanism is driven by the injection drive mechanism to penetrate from the surface of the tire being tested into its interior, and the temperature measuring needle collects the temperature at that location.

[0025] S04: After the temperature measurement is completed, the injection drive mechanism drives the temperature measuring needle to reset, and the temperature measuring drive device drives the mounting bracket to reset the injection mechanism.

[0026] The beneficial effects of this invention are:

[0027] In practical applications, the setup and method of this high-acceleration tire test injection temperature measurement device involve the following steps: During the test of the tire, the temperature measurement drive device moves the mounting frame closer to the tire, thereby moving the injection mechanism to the test position on the tire. The injection drive mechanism then moves the temperature measuring needle and inserts it into the tire from its surface. The temperature measuring needle collects temperature data at the test position on the tire, facilitating tire performance testing to meet the requirements of high-acceleration tire testing.

[0035] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0036] like Figures 1 to 7 As shown, the present invention provides a tire high-acceleration test injection temperature measurement device, including a mounting frame 1, an injection mechanism 2 disposed on the mounting frame 1, and a temperature measurement drive device 3 for driving the mounting frame 1 to move the injection mechanism 2 closer to or away from the tire 01 under test; the injection mechanism 2 includes a temperature measuring needle 21 and an injection drive mechanism 22 for driving the temperature measuring needle 21 to move.

[0037] In practical applications, this high-acceleration tire test injection temperature measuring device is set on one side of the loading head 02 of the tire under test 01 on the test bench. During the test of the tire under test 01, the temperature measuring drive device 3 drives the mounting frame 1 to move and approach the tire under test 01, thereby moving the injection mechanism 2 to the test position of the tire under test 01. The injection drive mechanism 22 drives the temperature measuring needle 21 to move and insert the temperature measuring needle 21 into the interior of the tire under test 01 from the surface. The temperature measuring needle 21 collects the temperature at the test position of the tire under test 01, which facilitates the performance testing of the tire and meets the requirements of high-acceleration tire testing.

[0038] In this embodiment, the injection mechanism 2 further includes an injection mounting base 23 mounted on the mounting frame 1, and the injection driving mechanism 22 is mounted on the injection mounting base 23. The injection driving mechanism 22 is provided with an adjusting cylinder 221 with external threads. At least two adjusting members 222 are threadedly connected to the adjusting cylinder 221, and the two adjusting members 222 lock the adjusting cylinder 221 to the injection mounting base 23. Specifically, the injection mounting base 23 is provided with a mounting surface 231, the adjusting cylinder 221 passes through the mounting surface 231, and the two adjusting members 222 are located on both sides of the mounting surface 231 and lock the mounting surface 231. In use, by adjusting the mounting position of the two adjusting members 222 on the adjusting cylinder 221, the extension length of the injection driving mechanism 22 and the temperature measuring needle 21 can be adjusted. This allows for adjustment and control of the depth of the temperature measuring needle 21 penetrating the tire 01 being tested, and adapts to the temperature measurement of different tire models. It is convenient to adjust and has a wide range of applications.

[0039] In this embodiment, the injection mechanism 2 is further provided with a limiting cylinder 223 with external threads and a limiting member 224 threadedly connected to the limiting cylinder 223. The limiting cylinder 223 is provided with a limiting groove 2231, and a limiting pin 225 is movably provided in the limiting groove 2231. The limiting pin 225 is located outside the limiting member 224. The injection driving mechanism 22 is further provided with an execution driving rod 226. One end of the execution driving rod 226 extends into the limiting cylinder 223 and is connected to the limiting pin 225. The temperature measuring needle 21 is drivenly connected to the other end of the execution driving rod 226.

[0040] Specifically, the injection drive mechanism 22 is a pneumatic cylinder, hydraulic cylinder, or electric cylinder, and the actuation drive rod 226 is a pneumatic cylinder rod, hydraulic cylinder rod, or electric cylinder rod.

[0041] In use, the limiting member 224 can be connected to the required position on the limiting cylinder 223 as needed. The distance between the limiting member 224 and the end of the limiting groove 2231 near the limiting pin 225 is the range of motion of the limiting pin 225, which is the stroke range of the actuator 226 of the injection drive mechanism 22 and the temperature measuring needle 21. By adjusting the installation position of the limiting member 224 on the limiting cylinder 223, the stroke of the temperature measuring needle 21 can be controlled, thereby controlling the depth of the temperature measuring needle 21 into the tire 01 being tested, and adapting to the testing of various tire models. It is easy to adjust and has a wide range of applications.

[0042] In this embodiment, the injection drive mechanism 22 is connected to a cylinder 227 for protecting the temperature measuring needle 21. When the temperature measuring needle 21 is not injecting and measuring the temperature of the tire 01 being tested, the temperature measuring needle 21 is located in the cylinder 227. In use, the cylinder 227 is placed against the temperature measuring position of the tire 01 being tested, and the temperature measuring needle 21 extends out from the cylinder 227 and inserts into the tire 01 being tested. The cylinder 227 serves to guide and position the temperature measuring needle 21.

[0043] In this embodiment, multiple injection mechanisms 2 are provided; the multiple injection mechanisms 2 are respectively used to inject and measure the temperature of the tread, shoulder and sidewall of the tire under test 01, so as to obtain the temperature of each stress-bearing part, which facilitates the experimental analysis of the complex stress environment of the tire under test 01.

[0044] In this embodiment, the mounting frame 1 is provided with a receiving space 4 for accommodating the tire 01 to be tested; two injection mechanisms 2 are provided for injecting and measuring the temperature of the tire shoulder and sidewall of the tire 01 to be tested, and the two injection mechanisms 2 are distributed on both sides of the receiving space 4. When injecting and measuring the temperature of the tire 01 to be tested, the tire 01 to be tested is positioned in the receiving space 4, and the multiple injection mechanisms 2 on both sides of the receiving space 4 respectively inject and measure the temperature of the tire 01's tread, both tire shoulders and sidewall.

[0045] In this embodiment, the mounting frame 1 is provided with two symmetrically arranged mounting parts 11. Each mounting part 11 has a connecting portion 111, a tire shoulder detection mounting portion 112 connected to the connecting portion, and a tire sidewall detection mounting portion 113 connected to the tire shoulder detection mounting portion 112. Specifically, the connecting portion 111, the tire shoulder detection mounting portion 112, and the tire sidewall detection mounting portion 113 of the mounting part 11 adopt a bent integral molding structure. Its segmented structure design facilitates the installation of the injection mechanism 2 and its matching with the tire shape. In actual use, the installation position of the injection mechanism 2 on the connecting portion 111, the tire shoulder detection mounting portion 112, or the tire sidewall detection mounting portion 113 can be adjusted to adapt to the injection temperature measurement of different tire models.

[0046] In this embodiment, both the tire shoulder detection mounting part 112 and the tire sidewall detection mounting part 113 are equipped with the injection mechanism 2, and the injection mechanism 2 is installed between the two connecting parts 111. The two mounting parts 11 and the injection mechanism 2 between the two connecting parts 111 form the accommodating space 4, so that multiple injection mechanisms 2 are installed around the tread, both tire shoulders and the tire sidewall of the tire under test 01 to achieve multi-point temperature collection of the tire under test 01, thereby improving the accuracy of the experiment. Specifically, the accommodating space 4 has a funnel-shaped opening to facilitate the entry and exit of the tire under test 01.

[0047] In this embodiment, the mounting frame 1 is further provided with a width adjusting component 12 connected to the connecting part 111, a width adjusting mounting component 13, a height adjusting mounting component 14 connected to the width adjusting mounting component 13, and a movable frame 15; the width between the two mounting components 11 is adjusted by adjusting the installation positions of the width adjusting component 12 and the width adjusting mounting component 13; the height of the injection mechanism 2 is adjusted by adjusting the installation positions of the height adjusting mounting component 14 and the movable frame 15; the movable frame 15 is driven and connected to the temperature measuring drive device 3 to adapt to the experiment of different tire models.

[0048] Specifically, a drive mechanism can be provided on the width adjustment mounting part 13 to drive the width adjustment part 12 to move, so as to adjust the installation position of the two; or a width mounting groove can be directly provided on the width adjustment mounting part 13, and screws can be used to lock the width adjustment part 12 and the width adjustment mounting part 13 at any position along the direction.

[0049] In this embodiment, the movable frame 15 is connected to a guide member 16, and the guide member 16 is slidably connected to a guide seat 17. The guide seat 17 is used to connect with the test bench frame, so that the injection mechanism 2 moves more smoothly when it approaches or moves away from the tire 01 being tested.

[0050] This invention also provides a method for measuring tire temperature by injection during high-acceleration testing, comprising the following steps:

[0051] S01: A needle-punching temperature measuring device 03 is installed on one side of the loading head 02 of the tire under test 01 on the test bench;

[0052] S02: During the tire performance test, the temperature measuring drive device 3 of the injection temperature measuring device 03 drives the mounting frame 1 with the injection mechanism 2 to approach the tire under test 01; and makes the tire under test 01 located in the accommodating space 4 of the mounting frame 1 with multiple injection mechanisms 2 around it.

[0053] S03: At the tread, both sides of the tire shoulder and the sidewall of the tire being tested, the temperature measuring needle 21 of the injection mechanism 2 is driven by the injection drive mechanism 22 to penetrate from the surface of the tire being tested into its interior, and the temperature measuring needle 21 collects the temperature at that location.

[0054] S04: After the temperature measurement is completed, the injection drive mechanism 22 drives the temperature measuring needle 21 to reset, and the temperature measuring drive device 3 drives the mounting bracket 1 to reset the injection mechanism 2.
