Description

Technical Field

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

[0002] Tires are the carriers of force transmission between vehicles and the road surface. Driving force, braking force, steering force, etc. are transmitted through tires, thereby realizing the driving, braking, steering and other operations of the car. As the only part of the car that contacts the ground, the performance of the tire directly affects the safety of the driver and passengers of the vehicle. The importance of tire performance can be imagined. For this reason, various countries have also made clear requirements for tire safety performance.

[0003] In Chinese utility model patents, for example, the utility model of CN217212070U discloses a vehicle tire wear resistance detection device. The utility model can adjust the pressure between the chuck and each detection plate by setting a chuck that can move up and down, and test the tire by setting a plurality of detection plates with different friction forces, thereby simulating the wear resistance of the tire in different use environments and improving the accuracy of the tire wear resistance detection data.

[0004] However, the above technology does not take into account the problem of tire wear. When the tire continues to rub against the test plate, the tire will wear and the contact area between the tire and the test plate will be reduced, making the measured wear data inaccurate and different from the wear conditions in actual use. It is impossible to accurately predict the wear resistance of the tire after long-term use. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-4 A vehicle tire wear resistance detection device comprises a box body 1, a cooling mechanism is arranged in the box body 1, the cooling mechanism comprises a water collecting box 2, and the water collecting box 2 is fixedly installed in the box body 1, a honeycomb panel 17 is fixedly installed on the bottom wall of the box body 1, and the honeycomb panel 17 is connected with the water collecting box 2, the water collecting box 2 is connected with a water pump 3, and the water pump 3 is fixedly installed on the side of the box body 1, the other end of the water pump 3 is connected with a connecting pipe 4, and the other end of the connecting pipe 4 is connected with a nozzle 16, and the nozzle 16 is fixedly installed on the top surface of the box body 1, and the water pump 3 is started, and the water source in the water collecting box 2 is cooled through the nozzle 16 to cool the tire after the test, so that the surface temperature of the tire quickly reaches the temperature that can be considered as touching, so as to facilitate the next experiment, and at the same time, the water sprayed by the nozzle 16 enters the water collecting box 2 through the honeycomb panel 17 through the setting of the honeycomb panel 17, so as to realize the circulation of water and avoid the waste of water resources;

[0024] A plurality of hydraulic cylinders 6 are symmetrically mounted on the top wall of the box body 1, and a pressure sensor is mounted in each hydraulic cylinder 6. A controller is fixedly mounted on the outside of the box body 1, and each pressure sensor is electrically connected to the controller. The pressure value can be set through the controller, and then the specified pressure is used to perform wear resistance test on the tire, so as to simulate the actual use conditions as realistically as possible, so as to obtain more universal test results. A support seat 5 is commonly mounted on the bottom surface of the plurality of hydraulic cylinders 6, and a second motor 15 is fixedly mounted on the side of the support seat 5. The output shaft of the second motor 15 passes through the support seat 5 and is connected to the assembly seat 7. A telescopic box 10 is slidably connected to the bottom wall of the box body 1, and a plurality of springs 14 are arranged in the telescopic box 10. A detection plate assembly 13 is fixedly mounted on the top surface of the telescopic box 10. The detection plate assembly 13 includes a plurality of detection plates, and the plurality of detection plates are installed in parallel, and the plurality of detection plates are of different types. By moving the telescopic box 10, the tire can be tested for wear resistance on different detection plates, so that it can be tested under different friction forces, so as to obtain more accurate test results.

[0025] A driving structure is provided in the box body 1, and the detection plate assembly 13 pushes the telescopic box 10 to slide through the driving mechanism. The driving mechanism includes a first motor 8, and the first motor 8 is fixedly installed on the side wall of the box body 1. The output shaft of the first motor 8 is connected to a threaded rod 9, one end of the threaded rod 9 is threadedly connected to a threaded sleeve 11, and the other end of the threaded sleeve 11 is fixedly installed on the side of the telescopic box 10. By starting the first motor 8, the telescopic box 10 is driven to slide.

[0026] A cavity 18 is provided in the threaded sleeve 11, and a baffle 12 is fixedly installed at one end of the threaded rod 9 away from the first motor 8, and the baffle 12 is slidably connected in the cavity 18. The threaded sleeve 11 is separated from the threaded rod 9 through the baffle 12. At the same time, since the other end of the threaded sleeve 11 is fixedly installed on the telescopic box 10, the telescopic box 10 limits the threaded sleeve 11, making it unable to rotate and only capable of linear movement.

[0027] When the utility model is used, the staff fixes the tire on the output shaft of the second motor 15 through the assembly seat 7, and then starts the multiple hydraulic cylinders 6 to move the support seat 5 downward, thereby driving the tire and the detection plate assembly 13 to abut against each other, and then the second motor 15 can be started to drive the assembly seat 7 to rotate, thereby driving the detection plate of the tire on the detection plate assembly 13 to perform a wear test. When the test is completed, the water source in the water collecting tank 2 is started by starting the water pump 3 to enter the nozzle 16 from the connecting pipe 4, thereby quickly cooling the tire surface, so that the staff can quickly prepare for the next test. At the same time, the water source can be recirculated to the water collecting tank 2 through the setting of the honeycomb plate 17, thereby realizing the internal circulation of water and preventing the waste of water resources.

[0028] When it is necessary to test the tires under different friction forces, the first motor 8 can be started to drive the telescopic box 10 to move, so that the detection plate assembly 13 can be adjusted in position, and then different detection plates can be aligned with the tires. It is worth mentioning that a plurality of springs 14 are installed in the telescopic box 10. When the tire is continuously rubbed against the detection plate, the rubber on the tire will be worn, thereby reducing the contact between the tire and the detection plate, affecting the detection result. The setting of multiple springs 14 can make the tire and the detection plate always resist each other, thereby ensuring the tire detection result.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
