[0018] Please refer to Figures 1-4 : in the embodiment, a kind of wear-resistant lubricated automobile steering knuckle, including support 1 and inclined plate 3, the bottom of support 1 is fixedly connected with the top of inclined plate 3, the bottom of inclined plate 3 is fixedly connected with steering knuckle 4, the front surface of steering knuckle 4 is connected with straight pipe 6, the inner wall of straight pipe 6 is processed with thread, the inner wall of straight pipe 6 is connected with control structure 2.

[0019] Control structure 2 includes threaded pipe 201 and bottle body 202, the outer wall of threaded pipe 201 is connected with the inner wall of straight pipe 6 with thread, the front surface of threaded pipe 201 is connected with the rear end surface of bottle body 202, bottle body 202 is transparent plastic bottle, the upper and lower two sides of bottle body 202 front end are fixedly connected with straight board 203 respectively;

[0020] By controlling the injection of lubricating liquid at the threaded pipe 201 in the structure 2, the lubricating liquid enters the bottle body 202, and then after the knuckle 4 is fixed, the hand and the straight plate 203 form a force point, and then the hand rotates the straight plate 203 with the bottle body 202, the rotating bottle body 202 brings the outer wall of the threaded pipe 201 into threaded connection with the inner wall of the straight pipe 6, until the outer wall of the bottle body 202 is attached to the front of the straight pipe 6, at this time, due to the inclined surface of the inner wall of the bottle body 202 to the threaded pipe 201, the internal lubricating oil will flow to the threaded pipe 201, and finally through the threaded pipe 201 into the circular groove 5, changing the original form of hard friction through materials, improving the wear resistance of the automobile knuckle, and ensuring the service life of the automobile knuckle.

[0021] The left top of the knuckle 4 is fixedly connected with the right bottom of the support 1, the inner wall of the knuckle 4 is processed with a circular groove 5, the circular groove 5 is communicated with the straight pipe 6, the lubricating liquid can enter the circular groove 5 through the straight pipe 6, the inner wall of the knuckle 4 is inserted with the outer wall bottom of the steering rod 7, and the steering rod 7 and the knuckle 4 are a matched structure.

[0022] Working principle:

[0023] Automobile knuckle installation:

[0024] A layer of lubricating grease (white paste) is first applied in the circular groove 5 of the inner wall of the knuckle 4, the inner wall of the knuckle 4 is inserted with the outer wall bottom of the steering rod 7, at this time, the left support 1 and the right connecting plate are attached to the connection of the bottom of the vehicle body, then the bolts pass through the circular port of the outer wall of the support 1 and the connecting plate and are fixed with the bottom of the vehicle body, and the installation of the automobile knuckle is completed.

[0025] Automobile knuckle lubrication installation:

[0026] The lubricating liquid is injected at the threaded pipe 201, so that the lubricating liquid enters the bottle body 202, and then after the knuckle 4 is fixed, the hand and the straight plate 203 form a force point, and then the hand rotates the straight plate 203 with the bottle body 202, the rotating bottle body 202 brings the outer wall of the threaded pipe 201 into threaded connection with the inner wall of the straight pipe 6, until the outer wall of the bottle body 202 is attached to the front of the straight pipe 6, at this time, due to the inclined surface of the inner wall of the bottle body 202 to the threaded pipe 201, the internal lubricating oil will flow to the threaded pipe 201, and finally through the threaded pipe 201 into the circular groove 5, at this time, the lubricating grease in the circular groove 5 will block the lubricating oil outside, the steering rod 7 is inserted with the knuckle 4, the lubricating grease will contact with the steering rod 7, when the vehicle body controls the steering rod 7 to rotate in the knuckle 4, friction is generated between the two, the friction generates heat, at this time, the lubricating grease forms friction protection for the steering rod 7 and the knuckle 4, and the heat generated by the friction causes the lubricating grease to evaporate, after the lubricating grease is consumed, the lubricating oil will gradually enter the circular groove 5, and then the lubricating oil will replace the lubricating grease to perform friction protection for the knuckle 4 and the steering rod 7.
