Description

Technical Field

[0001] The utility model relates to the technical field of a tire steering resistance test device, in particular to a vehicle tire steering resistance test device. Background Art

[0002] After a car is produced, it is often subjected to a series of tests, including a tire steering resistance test, which can be used to detect the quality of the car's tires and steering system.

[0003] The existing technology of automobile tire steering resistance test is mainly a whole vehicle simulation. The test vehicle is driven to a designated location, and then the steering wheel is driven by a driving device to rotate. At the same time, the rotation force is recorded, so that the automobile tire steering resistance can be obtained.

[0004] However, it is rather troublesome to test the steering resistance of automobile tires, especially due to site limitations. The test can only be carried out on one site, and it is impossible to obtain the data of the steering resistance of automobile tires on other roads, which brings a certain degree of singleness to the test results.

[0005] Therefore, we propose a vehicle tire steering resistance test device that can perform tests on a variety of ground surfaces and avoid the impact of a variety of ground surfaces to solve the above problems. Utility Model Content

[0006] The utility model aims to provide a vehicle tire steering resistance test device to solve the problems raised in the above background technology.

[0007] The purpose of the utility model can be achieved through the following technical solutions:

[0008] A vehicle tire steering resistance test device comprises a test bench, both ends of the test bench are symmetrically fixedly connected with ramps, the top of the test bench is symmetrically provided with grooves, the bottom ends of the grooves are fixedly connected with flat plates, a ground simulation frame is placed in the groove on one side of the flat plate, both sides of the test bench are symmetrically fixedly connected with slide rails, a slide plate is slidably connected to the slide rails, the top ends of the slide plates are fixedly connected with mounting plates, the upper ends of the mounting plates are fixedly connected with a servo motor, the output end of the servo motor is fixedly connected with a rotating frame, arc plates are arranged on both sides of the rotating frame, and cleaning cotton is fixedly connected to the inner sides of the arc plates.

[0009] As a further solution of the utility model: the interior of the ground simulation frame is filled with any one of soil, sand, concrete and asphalt.

[0010] As a further solution of the utility model: the side walls of the test bench on one side of the ground simulation frame are slidably connected with a push plate, and the bottom end of the ground simulation frame on one side of the push plate is symmetrically fixedly connected with a top plate.

[0011] As a further solution of the utility model: the top end of the push plate and the bottom end of the top plate are parallel, and the push plate and the top plate are both trapezoidal.

[0012] As a further solution of the utility model: one end of the push plate away from the test bench is fixedly connected with a connecting plate, and the connecting plate is fixedly connected to the slide plate.

[0013] As a further solution of the utility model: handle grooves are provided on both sides of the ground simulation frame, and the top of the ground simulation frame is lower than the top of the test bench.

[0014] As a further solution of the utility model: the arc plate penetrates and is slidably connected to the side wall of the rotating frame, and one end of the arc plate is fixedly connected to the rotating frame through a nut.

[0015] Beneficial effects of the utility model:

[0016] 1. A vehicle tire steering resistance test device in the utility model drives a test vehicle to the top of a ground simulation frame, drives the steering wheel to rotate through a driving device, so that the vehicle tire rotates on the ground simulation frame and records the resistance required for steering, and then replaces the ground simulation frame. According to the above steps, the steering resistance data of the vehicle tire on soil, gravel, concrete and asphalt are finally obtained to ensure the accuracy and comprehensiveness of the test results.

[0017] 2. After a single test is completed, the vehicle tire steering resistance test device in the utility model can push the slide plate to allow the cleaning cotton to clamp the vehicle tire on the flat plate. At this time, the servo motor drives the rotating frame to rotate, so that the cleaning cotton repeatedly rubs on the vehicle tire to reduce the impact of sand, gravel and soil in the previous test.

[0018] 3. When the slide plate is pushed, the automobile tire steering resistance test device in the utility model will drive the connecting plate to move the push plate, thereby pushing the top plate to lift up the ground simulation frame, so that the staff can take out the ground simulation frame by hand through the handle groove for replacement.

[0027] like Figure 1-Figure 5 In the present embodiment, a vehicle tire steering resistance test device comprises a test bench 1, both ends of the test bench 1 are symmetrically fixedly connected with a slope 2, the top of the test bench 1 is symmetrically provided with a groove 12, the bottom end of the groove 12 is fixedly connected with a plate 8, a ground simulation frame 3 is placed inside the groove 12 on one side of the plate 8, both sides of the test bench 1 are symmetrically fixedly connected with a slide rail 13, a slide plate 5 is slidably connected to the slide rail 13, the top of the slide plate 5 is fixedly connected with a mounting plate 6, the upper end of the mounting plate 6 is fixedly connected with a servo motor 7, the output end of the servo motor 7 is fixedly connected with a rotating frame 9, both sides of the rotating frame 9 are provided with an arc plate 10, and the inner side of the arc plate 10 is fixedly connected with a cleaning cotton 16.

[0028] like Figure 1 and Figure 3 In this embodiment, the interior of the ground simulation frame 3 is filled with any one of soil, gravel, concrete and asphalt, so as to facilitate the testing of automobile tires on different road surfaces.

[0029] like Figure 1 , Figure 3 and Figure 4In this embodiment, the side wall of the test bench 1 on one side of the ground simulation frame 3 is slidably connected with a push plate 11, and the bottom end of the ground simulation frame 3 on one side of the push plate 11 is symmetrically fixedly connected with a top plate 15. The push plate 11 moves to push the top plate 15 so that the ground simulation frame 3 is lifted up, thereby facilitating the staff to take it out for replacement.

[0030] like Figure 1 , Figure 3 and Figure 4 In this embodiment, the top end of the push plate 11 and the bottom end of the top plate 15 are parallel, and both the push plate 11 and the top plate 15 are trapezoidal, thereby ensuring that the push plate 11 can stably lift the top plate 15.

[0031] like Figure 1 and Figure 4 In this embodiment, the push plate 11 is fixedly connected to the connecting plate 4 at one end away from the test bench 1, and the connecting plate 4 is fixedly connected to the slide plate 5, so that the slide plate 5 can move to drive the connecting plate 4 to move the push plate 11.

[0032] like Figure 1-Figure 3 In this embodiment, both sides of the ground simulation frame 3 are provided with handle grooves 14 to facilitate the staff to take out or carry the ground simulation frame 3.

[0034] It can be understood that the automobile tire steering resistance test device can push the slide plate 5 so that the cleaning cotton 16 clamps the automobile tire on the flat plate 8, and cooperates with the servo motor 7 to clean the automobile tire to prevent the tire adhesion from affecting the next test.
