[0029] In order to illustrate the beneficial effects of the present application, the problems existing in the prior art are described here:

[0030] The automobile steering tie rod is an important component for controlling the vehicle's driving posture. Its failure may cause the following problems: 1. The vehicle is driving on a bumpy road, making abnormal noises, unstable driving, swaying from side to side, brake deviation, and steering failure; 2. The ball head is too heavy and is easy to break when receiving an impact load, resulting in the risk of failure to control the posture and causing the vehicle to be destroyed and people to die; 3. The loose ball head of the steering tie rod will cause the steering to deviate, the tires to tighten, the steering wheel to shake, and in severe cases, the ball head may fall off, causing the wheel to fall off instantly. However, in the prior art, there is a lack of muddy and water environment test equipment when the vehicle enters the factory for inspection, and it is impossible to verify the safety performance of the tie rod ball head.

[0031] Combination Figure 1 and Figure 2 As shown, according to an embodiment of the present application, a pull rod mud and water working condition detection device is provided.

[0032] Specifically, Figure 1 and Figure 2As shown, the mud and water working condition detection device of the tie rod includes a control box 10, an air circuit assembly 20 and a mud and water mixing box 30; the air circuit assembly 20 includes a first valve body 21 and a first tube body 22, the control box 10 is electrically connected to the first valve body 21, the first end of the first tube body 22 is used to connect to the compressed air source, the second end of the first tube body 22 is provided with a nozzle structure, and the first valve body 21 is used to open and close the pipeline between the compressed air source and the nozzle structure; the mud and water mixing box 30 includes a stirring motor 31 and a second tube body 32, the first end of the second tube body 32 extends into the mud and water mixing box 30, the second end of the second tube body 32 is connected to the first tube body 22 between the first valve body 21 and the nozzle structure, the stirring motor 31 is electrically connected to the control box 10, the stirring motor 31 is used to stir the mud and water in the mud and water mixing box 30, the first end of the second tube body 32 is used to extract the mud and water in the mud and water mixing box 30 and spray it to the ball head structure to be tested through the nozzle structure, wherein the ball head structure is a connecting ball head of the vehicle tie rod assembly.

[0033] By applying the technical solution of this embodiment, after the device is started, the stirring motor 31 begins to stir the mud and water, the first valve body 21 is turned on to open the compressed air source, and the compressed air passes through the first tube body 22, causing the second tube body 32 to generate negative pressure to suck the mud and water into the air pipe, and the mud and water are sprayed out through the nozzle structure along with the compressed air. The wear condition, failure condition and changes in performance parameters such as torque of the test ball head of the tie rod assembly under mud and water working conditions can be tested, which is more in line with actual usage.

[0034] Specifically, the control box 10 includes a box body, a start-stop button 11, a timer 12 and a counter 13; the start-stop button 11 is connected to the box body, and is used to control the working state of at least one of the first valve body 21 and the stirring motor 31; the timer 12 is connected to the box body, and is used to record the working time of at least one of the nozzle structure and the stirring motor 31; the counter 13 is connected to the box body, and is used to record the number of sprays of the nozzle structure. In this way, the number of sprays and the working time of the nozzle structure can be recorded by the timer 12 and the counter 13, and the number of sprays and the spraying time can also be pre-set. The start and stop of the detection device can be controlled by the start-stop button 11, that is, the stirring motor 31 starts to stir the muddy water and the first valve body 21 starts the compressed air source to generate negative pressure in the first tube body 22 to absorb the muddy water through the nozzle structure and spray it to the ball head structure, which is convenient to operate.

[0035] It should be noted that the number of spraying times and working time can be pre-set, and can also be temporarily adjusted during the test. The start-stop button 11 can automatically close to complete the test when the preset working time and the preset number of spraying times are reached, or it can be manually controlled to close during the test to facilitate the recording or replacement of the ball head structure performance parameters.

[0038] In one embodiment of the present application, the mud-water mixing box 30 has a plurality of side edges and at least one bottom edge, and the plurality of side edges and at least one bottom edge are arranged to form the mud-water mixing box 30. The plurality of side edges and the bottom edge are arranged in a regular polygonal prism shape to form the mud-water mixing box 30, and such an arrangement enables the stirring motor 31 to stir the mud-water quickly and evenly, so that the device can quickly enter the working state.

[0039] It should be noted that the stirring motor 31 is arranged at the top of the mud and water mixing box 30, and can also be arranged at the bottom of the mud and water mixing box 30. When the stirring motor 31 is arranged at the bottom of the mud and water mixing box 30, multiple bottom edges can be arranged at intervals, and the stirring motor 31 is placed in the interlayer of two adjacent bottom edges. The stirring motor 31 has a normal working state and a low-speed stirring state. The normal working state can quickly and evenly stir the mud and water, and the low-speed stirring state can keep the mud and water turbid and not precipitate.

[0040] Furthermore, an adjustment bracket 40 is provided on at least one side wall of the mud-water mixing box 30, and the adjustment bracket 40 is adjustably provided along the height direction of the mud-water mixing box 30. This arrangement can adjust the height of the nozzle structure, so that the sprayed mud water can test the standard spray ball head structure according to different heights. It should be noted that the adjustment bracket 40 can be attached to the inner side of the mud-water mixing box 30, that is, it is provided inside the mud-water mixing box 30, and can also be attached to the outer side of the mud-water mixing box 30.

[0041] Specifically, the maximum height of the adjusting bracket 40 is higher than the maximum height of the mud-water mixing box 30, the first end of the adjusting bracket 40 is connected to the mud-water mixing box 30, and the second end of the adjusting bracket 40 is movably connected to the nozzle structure. This arrangement can improve the reliability of the adjusting bracket 40 and prevent mud and water from being sprayed on the side of the mud-water mixing box 30. It should be noted that the adjusting bracket 40 can be integrally formed with the mud-water mixing box 30 to improve the reliability of the adjusting bracket 40.

[0042] Furthermore, the rod mud and water working condition detection device also includes a reflux component 50, which includes a protective cover 51, a water receiving tank 52 and a reflux pipe 53.

[0044] First, set the running time through the timer 12, press the start-stop button 11 to start the device, the stirring motor 31 starts to run and stir the mud and water, the first valve body 21 starts to conduct and open the compressed air source, and the compressed air passes through the first tube body 22, causing the second tube body 32 to generate negative pressure, and then the mud and water are sucked into the first tube body 22. A filter cover 34 is arranged outside the second tube body 32 to filter larger stones. The mud and water are sprayed out from the nozzle structure along with the compressed air. The nozzle structure can be height-adjusted by adjusting the bracket 40 so that the mud and water sprayed from the nozzle structure can adhere to the ball head structure to be tested. The air pressure can also be adjusted through the second valve body 24 to adjust the amount of mud and water sprayed. The protective cover 51 can prevent the mud and water from splashing out of the device, the water receiving tank 52 recovers the mud and water after the test, and the reflux pipe 53 returns the mud and water to the mud and water mixing box 30.
