Description
Technical Field
[0001] This invention relates to the technical field of tire testing, and in particular to a test bench for the correlation between tire wear resistance and water drainage performance. Background Technology
[0002] Tires are circular, elastic rubber products that are mounted on various vehicles or machinery and roll on the ground. They are usually mounted on wheel rims, supporting the vehicle body, buffering external impacts, making contact with the road surface, and ensuring the vehicle's driving performance. Before leaving the factory, tires must undergo wear resistance and water drainage tests to check whether they meet the usage requirements. Generally, tire testing is divided into two methods: one method is to directly mount the tire onto the test vehicle and install various sensors on the vehicle, then drive the vehicle on the test site. Although this method can realistically reflect tire problems, it requires a large area and the test equipment needs to be set up on the site, which is time-consuming and labor-intensive. In addition, the test vehicle needs to be driven by personnel, which poses a greater risk to the personnel.
[0003] Another method is to use a tire drainage test bench and an abrasion test bench to test the drainage and abrasion resistance of the tires.
[0004] Among them, the drainage test bench, such as the tire tread drainage test bench disclosed in the utility model patent with announcement number CN206818429U, is mainly composed of a base frame, a rotating belt device and a water reservoir. When in use, the rotating belt is used to simulate the ground contacted by the tire under test, instead of the traditional rotating drum to simulate the ground, which is more in line with the actual operating conditions of the tire and the test results are more accurate and reliable. At the same time, the structure of the test bench is more compact. However, due to its relatively simple structure, the hardness and compactness of the rotating belt are low, making it difficult to simulate real road conditions. In addition, the experiment is relatively simple and inconvenient to conduct experiments in other environments.
[0005] The wear resistance testing bench, such as the automobile tire wear resistance testing device disclosed in utility model patent CN211697341U, mainly consists of a wear resistance testing base, shock absorption device, and drive motor. During use, the first and second wear resistance testing structures allow for simultaneous wear resistance testing of two tires, improving the efficiency of wear resistance testing and reducing the workload of testing personnel. However, due to its relatively simple structure, it is difficult to simulate the friction between tires and real road surfaces, and it is inconvenient to conduct experiments in other environments. Similarly, both the drainage testing bench and the wear resistance testing bench make it difficult to conduct experiments on the correlation between tire wear resistance and drainage performance, resulting in poor practicality. Therefore, improvements to existing equipment are needed. Summary of the Invention
[0006] To address the aforementioned technical problems, this invention provides a tire wear resistance and water drainage performance correlation test bench. The bench mounts a tire onto a drive mechanism, uses a detection mechanism to measure the tire's tread pattern quantity and depth, and the temperature and humidity around the tire. It then adjusts the water level in a drainage testing mechanism or sprays water onto a road condition adjustment mechanism, and uses a temperature adjustment mechanism and an aging mechanism to regulate the tire's temperature aging. Finally, the drive mechanism rotates the tire, moving it on the road condition adjustment mechanism to perform drainage and wear resistance tests, thereby improving the practicality of the equipment.
[0007] The present invention provides a tire wear resistance and drainage performance correlation test bench, including a braking device; it also includes a drainage volume testing mechanism, a drive mechanism, a temperature regulation mechanism, an aging mechanism, a road condition regulation mechanism, a detection mechanism, and a protective mechanism.

[0008] The testing mechanism detects the number and depth of tire treads, water drainage, and the temperature and humidity around the tire. The water drainage testing mechanism tests the tire's water drainage and acid rain resistance. The drive mechanism provides power to the tire. The road condition adjustment mechanism adjusts the road conditions and performs wear resistance tests on the tire. The temperature adjustment mechanism adjusts the tire temperature. The protection mechanism isolates the test area.
[0009] The tire is mounted on the drive mechanism. The detection mechanism measures the number and depth of the tire tread pattern and the temperature and humidity around the tire. Then, the water level in the water displacement testing mechanism is adjusted or water is sprayed onto the road condition adjustment mechanism. The temperature aging of the tire is adjusted by the temperature adjustment mechanism and the aging mechanism. Finally, the drive mechanism drives the tire to rotate and move on the road condition adjustment mechanism to perform water displacement and wear resistance tests, thereby improving the practicality of the equipment.
[0010] Preferably, the drainage capacity testing mechanism includes a water tank, a drainage pump, a storage tank, a spray pipe, and a bracket. The drainage pump is installed on the side of the water tank, and both the left and right bottom ends of the drainage pump have suction ports, while the top right end has a drain port.

The storage tank is installed on the drainage pump, and the suction port on the left end of the drainage pump communicates with the interior of the storage tank. The drain port of the drainage pump is connected to one end of the spray pipe, which is located inside the water tank and has multiple nozzles. The bracket is installed at the bottom of the water tank. Clean water is drained into the water tank. Inside the device, acidic liquid is discharged into a storage tank. By changing the water level in the tank, the thickness of the water film on the road condition adjustment mechanism is adjusted to simulate flooded road conditions. Alternatively, a drain pump can be turned on to draw clean water from the tank and discharge it into the spray pipe. The water is then sprayed onto the road condition adjustment mechanism through multiple nozzles on the spray pipe to simulate road conditions in rain. Or, by turning on the drain pump to draw clean water from the tank and discharge it into the spray pipe, the acidic liquid in the storage tank is simultaneously discharged into the spray pipe, mixing the acidic liquid with clean water before being sprayed onto the road condition adjustment mechanism to simulate road conditions in acid rain, thereby improving the practicality of the equipment.
[0011] Preferably, the road condition adjustment mechanism includes two sets of first hydraulic cylinders, two sets of fixed frames, a test platform, and a first drive motor. The two sets of first hydraulic cylinders are fixedly installed on the left and right ends of the water tank, respectively. The bottom ends of the two sets of fixed frames are connected to the top ends of the two sets of first hydraulic cylinders, and liquid level sensors are installed on the fixed frames. The left and right ends of the test platform are rotatably installed on the two sets of fixed frames, and the multiple sides of the test platform are for different road conditions. The first drive motor is installed on one set of fixed frames and drives the test platform. The test platform is supported by the brackets. In use, the two sets of first hydraulic cylinders extend to detach the test platform from the brackets, and then the first drive motor is turned on to drive the test platform to rotate, thereby adjusting the contact surface between the test platform and the tire. This facilitates tire testing on different road conditions, thereby improving the practicality of the equipment.
[0012] Preferably, the driving mechanism includes two sets of sliders, a first frame, a splined shaft sleeve, a shock absorber, a splined shaft, a second frame, a hub, a power mechanism, and a connecting shaft. The top of the water tank is provided with two sets of slide rails, and the two sets of sliders are slidably mounted on the two sets of slide rails respectively. The bottom end of the first frame is connected to the top end of the two sets of sliders, the top end of the splined shaft sleeve is connected to the top end of the first frame, the splined shaft is slidably mounted in the splined shaft sleeve, the shock absorber is installed between the splined shaft sleeve and the splined shaft, the top end of the second frame is connected to the bottom end of the splined shaft, the hub is rotatably mounted on the second frame, the power mechanism is slidably mounted on the rear end of the first frame, and the output shaft of the connecting shaft is connected to the rear end of the hub. The tire is mounted on the hub, and then the hub is rotatably mounted on the second frame. The power mechanism drives the hub to rotate, causing the tire to roll on the test bench to test the tire's wear resistance and drainage performance. Simultaneously, the shock absorber dampens the tire's vibration, thereby improving the practicality of the equipment.
[0013] Preferably, the temperature regulation mechanism includes a third frame, two sets of sealing plates, a support frame, two sets of second hydraulic cylinders, a steam generator, and a refrigerator. The experimental platform has multiple sets of gas supply pipes inside. The third frame is fixedly installed on the water tank, and a temperature sensor is installed inside the third frame. A heat dissipation pipe is installed at the front end of the third frame, and a cooling pipe is installed at the rear end. Exhaust fans are installed at the top and bottom of the third frame. The two sets of sealing plates are slidably installed at the left and right ends of the third frame, respectively, and their top ends are connected to the bottom end of the support frame. The two sets of second hydraulic cylinders are installed at the front and rear ends of the third frame, respectively. The steam generator and refrigerator are both installed at the top of the third frame. One end of the heat dissipation pipe is connected to the output port of the steam generator, and the other end is rotatably connected to the side end of the experimental platform. The interior of the heat dissipation pipe communicates with the gas supply pipes inside the experimental platform. One end of the gas supply pipe has an outlet, and the input port of the steam generator is located at the water tank. Inside the chamber, one end of the cooling pipe is connected to the output port of the refrigeration unit, and the other end is connected to the input port. A power mechanism drives the tires to rotate on the experimental platform, causing the first frame to enter the interior of the third frame. Two sets of second hydraulic cylinders retract, causing two sets of sealing plates to block the left and right ends of the third frame respectively. Water from the water tank then seals the bottom of the third frame. A steam generator draws water from the tank and heats it, then discharges the steam into the heat dissipation pipes, raising the temperature inside the third frame. Simultaneously, two sets of exhaust fans circulate air within the third frame. The steam is then discharged back into the water tank through the air supply pipes within the experimental platform, or circulated by the refrigeration unit in conjunction with the three cooling pipes, lowering the temperature inside the third frame. This process is repeated, with the two sets of exhaust fans circulating air within the third frame, thus improving the equipment's practicality.
[0014] Preferably, the aging mechanism includes an ozone generator, which is installed on the top of the third frame and the outlet of the ozone generator is connected to the interior of the third frame; ozone is generated by the ozone generator and discharged into the third frame to age the tires, thereby improving the practicality of the equipment.
[0015] Preferably, the detection mechanism includes a laser sensor, a water collection housing, a storage tank, and a drain pump. The laser sensor is installed on the top of the second frame, the water collection housing is installed on the right end of the second frame, and the storage tank and drain pump are both installed on the top of the water collection housing. A weight sensor is installed inside the storage tank. The drain outlet of the drain pump is connected to the inside of the storage tank, and the suction pipe of the drain pump is connected to the inside of the water collection housing. The laser sensor detects the number and depth of the tire tread pattern and the temperature and humidity around the tire. The water discharged from the tire is collected through the water collection housing. Then, the drain pump is turned on to drain the water from the water collection housing into the storage tank, where the water is stored. The weight sensor detects the weight of the water in the storage tank, which allows the operator to observe the amount of water discharged from the tire, thereby improving the practicality of the equipment.
[0016] Preferably, the protective mechanism includes a base plate, a sealed enclosure, an exhaust fan, two sets of observation windows, a sealed enclosure door, and two sets of cleaning mechanisms. The bottom end of the sealed enclosure is connected to the bottom end of the base plate, the bottom end of the exhaust fan is connected to the top end of the sealed enclosure, the two sets of observation windows are fixedly installed at the front and rear ends of the sealed enclosure, the sealed enclosure door is installed at the side end of the sealed enclosure, and the two sets of cleaning mechanisms are installed at the front and rear parts of the sealed enclosure. The bottom end of the water tank is connected to the top end of the base plate, and the water tank is located inside the sealed enclosure. The base plate and the sealed enclosure work together to isolate the experimental area, reducing the impact of flying debris during the experiment on the surrounding environment and personnel. Furthermore, after the heat dissipation pipe in the third frame discharges steam into the gas supply pipeline in the experimental platform, the moisture on the surface of the experimental platform evaporates. The base plate and the sealed enclosure work together to block water vapor, regulating the humidity around the tire, thereby improving the practicality of the equipment.
[0017] Preferably, the cleaning mechanism includes two sets of racks, two sets of sliders, two sets of second drive motors, two sets of gears, a connecting rod, and a scraper. Both sets of racks are installed inside the sealed housing. The two sets of sliders are slidably mounted on the two sets of racks, respectively. The two sets of second drive motors are fixedly mounted on the two sets of sliders, respectively. The two sets of gears are mounted on the output shafts of the two sets of second drive motors. The two sets of sliders are connected by a connecting rod, and the scraper is mounted on the connecting rod. When the two sets of second drive motors are turned on, the two sets of gears mesh with the two sets of racks, driving the two sets of sliders to slide on the two sets of racks, causing the scraper to remove water stains from the observation window. This facilitates observation of the tire testing process by the operator, thereby improving the practicality of the equipment.
[0018] Preferably, the experimental method includes the following steps:
[0019] S1. Drain clean water into the water tank, drain acidic liquid into the storage tank, install the tire onto the wheel hub, and then rotate the wheel hub onto the second frame.
[0020] S2. The wheel hub is driven to rotate by the power mechanism, causing the tire to roll on the test bench. This allows the first frame to enter the interior of the third frame. Two sets of second hydraulic cylinders retract, causing two sets of sealing plates to block the left and right ends of the third frame respectively. The bottom of the third frame is then sealed with water from the water tank. A steam generator draws water from the tank and heats it, then discharges the steam into the heat dissipation pipes, raising the temperature inside the third frame. Simultaneously, two sets of exhaust fans transport air into the third frame, causing it to circulate. The steam is then discharged back into the water tank through the air supply pipes in the test bench. Alternatively, the temperature inside the third frame can be lowered by circulating the air through a refrigeration unit in conjunction with three cooling pipes. This process is repeated, using two sets of exhaust fans to transport air into the third frame, or by generating ozone through an ozone generator and discharging it into the third frame. The ozone then ages the tire and adjusts its condition. At the same time, a laser sensor detects the number and depth of the tire tread pattern and the temperature and humidity around the tire.
[0021] S3. The power mechanism drives the wheel hub to rotate, causing the first frame to move to the outside of the third frame. Two sets of first hydraulic cylinders extend, detaching the experimental platform from the support. The first drive motor is then activated, rotating the experimental platform to adjust the contact surface between the platform and the tire. The top of the platform then presses against the bottom of the tire. Water is drained into the water tank, and the water level in the tank is adjusted to control the thickness of the water film on the road condition adjustment mechanism, simulating flooded road conditions. Alternatively, a drain pump is activated to draw water from the tank and discharge it into a spray pipe. Multiple nozzles on the spray pipe then spray water onto the road condition adjustment mechanism. Simulating road conditions in rain, or by turning on the drain pump to suck out clean water from the water tank and discharge it into the spray pipe, while simultaneously using the drain pump to discharge acidic liquid from the storage tank into the spray pipe, mixing the acidic liquid with clean water before spraying it onto the road condition adjustment mechanism, simulating road conditions in acid rain, then using the power mechanism to drive the wheel hub to rotate, causing the tire to roll on the test platform, while the water discharged by the tire is collected through the water collection shell, then the drain pump is turned on to discharge the water from the water collection shell into the storage tank, allowing the storage tank to store the water, and then the weight of the water in the storage tank is detected by the weight sensor, thereby measuring the amount of water discharged by the tire;
[0022] S4. Repeat the steps in S3 to adjust the tire's condition and the surrounding environment. Drive the wheel hub to rotate through the power mechanism, so that the first frame moves to the left side of the water tank and the left ends of the two sets of sliders press against the left side of the water tank. Continue to drive the wheel hub to rotate through the power mechanism, so that the tire rubs on the test bench and tests the tire's wear resistance.
[0023] S5. During the testing process, two sets of second drive motors are turned on, and two sets of gears are connected to two sets of racks respectively, driving two sets of sliders to slide on the two sets of racks respectively, so that the scraper scrapes off the water stains on the observation window, allowing the staff to observe the tire test process.
[0024] The beneficial effects of this invention are:
[0025] 1. The water displacement of the tires is tested by using a water displacement testing mechanism in conjunction with the drive mechanism and road condition adjustment mechanism;
[0026] 2. By using a drive mechanism in conjunction with a road condition adjustment mechanism, tire wear resistance is tested through burnout.
[0027] 3. The temperature regulation mechanism, in conjunction with the aging mechanism and the protection mechanism, adjusts the tire condition and the environment around the tire to simulate the actual use condition of the tire.
[0028] 4. Based on the test results of various tire conditions and environmental conditions, it is convenient for staff to judge the correlation between tire wear resistance and water resistance for different tires, different tire conditions and different environmental conditions;
[0029] 5. By simulating real-world conditions and conducting tests on the experimental platform, the setup of the surrounding environment is reduced, testing efficiency is improved, and the workload of staff is reduced. Attached Figure Description

[0055] like Figures 1 to 11As shown, the present invention discloses a test bench for the correlation between tire wear resistance and drainage performance. During operation, clean water is first drained into the water tank 1, and an acidic liquid is drained into the storage tank 3. The tire is then mounted on the hub 17, and the hub 17 is rotatably mounted onto the second frame 16. The hub 17 is driven to rotate by the power mechanism 18, causing the tire to roll on the test bench 8, allowing the first frame 11 to enter the interior of the third frame 20. Two sets of second hydraulic cylinders 23 retract, causing two sets of sealing plates 21 to respectively block the left and right ends of the third frame 20. Water from the water tank 1 then seals the bottom of the third frame 20. A steam generator 24 draws water from the water tank 1 and heats it, then the steam is discharged into the heat dissipation pipe, causing the third frame... The temperature inside frame 20 rises, and air is simultaneously supplied to the third frame 20 via two sets of exhaust fans, causing air to circulate within the third frame 20. The steam is then discharged back into the water tank 1 via the air supply pipes in the experimental platform 8, or the temperature inside the third frame 20 is lowered by circulating air through the refrigeration unit 25 in conjunction with three cooling pipes. This process is repeated, supplying air to the third frame 20 via two sets of exhaust fans, or generating ozone through the ozone generator 26 and releasing it into the third frame 20. The ozone is used to age the tires and adjust their condition. Simultaneously, the laser sensor 27 detects the number and depth of tire tread patterns and the temperature and humidity around the tires. Finally, the power mechanism 18 drives the wheel hub 1. 7. Rotate to move the first frame 11 to the outside of the third frame 20. Extend the two sets of first hydraulic cylinders 6 to detach the experimental platform 8 from the support 5. Then turn on the first drive motor 9 to drive the experimental platform 8 to rotate, adjusting the contact surface between the experimental platform 8 and the tire. Then, the top of the experimental platform 8 presses the bottom surface of the tire. Then, clean water is drained into the water tank 1. By changing the water level in the water tank 1, the thickness of the water film on the road condition adjustment mechanism is adjusted to simulate waterlogged road conditions. Alternatively, turn on the drain pump 2 to suck out the clean water in the water tank 1 and drain it into the spray pipe 4. The water is sprayed onto the road condition adjustment mechanism through multiple nozzles on the spray pipe 4 to simulate rainy road conditions. Alternatively, turn on the drain pump 2 to suck out the clean water in the water tank 1 and drain it into the spray pipe 4. At the same time, the drain pump 2 drains the stored water. The acidic liquid in tank 3 is discharged into the water spray pipe 4, where it mixes with water and is then sprayed onto the road condition adjustment mechanism to simulate road conditions in acid rain. Then, the power mechanism 18 drives the wheel hub 17 to rotate, causing the tire to roll on the test bench 8. Simultaneously, the water discharged from the tire is collected by the water collection shell 28. The drainage pump 30 is then turned on to drain the water from the water collection shell 28 into the storage tank 29, where the water is stored. The weight of the water in the storage tank 29 is detected by a weight sensor, thus determining the tire's drainage volume. The steps in S3 are repeated to adjust the tire's condition and the surrounding environment. The power mechanism 18 drives the wheel hub 17 to rotate, moving the first frame 11 to the left side of the water tank 1, causing the left ends of the two sets of sliders 10 to press against the left side of the water tank 1.The wheel hub 17 is continuously rotated by the power mechanism 18, causing the tire to rub against the test bench 8 to test the tire's wear resistance. During the test, two sets of second drive motors 38 are activated, which are connected to two sets of racks 36 via two sets of gears 39. This drives two sets of sliders 37 to slide on the racks 36, causing the scraper 41 to remove water stains from the observation window 34, allowing the staff to observe the tire's experimental process.
