[0002] The steering knuckle, also known as the "ram's horn", is one of the important parts of the steering axle of the car. It can make the car run stably and sensitively transmit the driving direction. The function of the steering knuckle is to transmit and bear the front load of the car, support and drive the front wheel to rotate around the kingpin to turn the car. When the car is running, it is subjected to variable impact loads, so it is required to have high strength.

[0003] The forklift steering knuckle needs to be lubricated during installation. After the lubricant is used up, it needs to be removed and re-lubricated. The operation process is rather cumbersome and greatly increases the time for applying the lubricant. Utility Model Content

[0019] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.

[0020] As shown in Figures 1-4, a self-lubricating forklift steering knuckle includes a steering knuckle shaft 10, a main mounting hole 11 and a secondary mounting hole 12 are fixed on the steering knuckle shaft 10, an oil filling hole is opened on the outer peripheral side of the steering knuckle shaft 10, and a sealing plug 15 is detachably installed in the oil filling hole, wherein a lubrication component is arranged in the steering knuckle shaft 10, a plurality of smear wheels are arranged in the main mounting hole 11, an oil storage tank is opened on the inner wall of the main mounting hole 11, and the smear wheel is located in the oil storage tank, and the smear wheel includes at least two small oiling rods 13 and a large oiling rod 14, wherein the large oiling rod 14 is located in the center of the small oiling rod 13;

[0021] The lubrication assembly includes a first one-way gear 22 and a second one-way gear 23 rotating in the steering knuckle shaft 10. The first one-way gear 22 and the second one-way gear 23 are both mounted on a screw 21. The screw 21 is also mounted with an oil squeezing plate 20. The lubricating oil can be squeezed onto the coating wheel by squeezing the lubricating oil through the screw 21, thereby lubricating the steering knuckle. An adjusting wrench is also slidably arranged in the steering knuckle shaft 10 to control the rotation of the first one-way gear 22 and the second one-way gear 23. An oil chamber 19 is opened in the steering knuckle shaft 10. The oil squeezing plate 20 is located in the oil chamber 19, and the oil squeezing plate 20 and the oil chamber 19 are both square in shape. The screw 21 penetrates into the oil squeezing plate 20. The screw 21 and the oil squeezing plate 20 are threadedly connected, and the screw 21 does not contact the bottom of the oil chamber 19.

[0022] An arc-shaped lever groove 17 is provided on the outer circumference of the steering knuckle shaft 10, and an I-shaped limit groove 18 is also provided in the lever groove 17. A lever 16 is slidably provided in the limit groove 18. A rack piece 24 is fixed to one end of the lever 16, and teeth are provided on the rack piece 24. The first one-way gear 22 and the second one-way gear 23 both rotate unidirectionally, and the directions of rotation are opposite. The outer circumferences of the first one-way gear 22 and the second one-way gear 23 are provided with teeth, which mesh with the rack piece 24.

[0023] When in use, semi-solid lubricating oil is injected from the oil filling hole to fill the oil chamber 19, and then the sealing plug 15 is installed. When the lubricating oil is needed, the lever 16 drives the rack piece 24 to mesh with the first one-way gear 22, and then under the limit of the limit groove 18, the lever 16 is pushed to drive the first one-way gear 22 to rotate. At this time, the rotation of the first one-way gear 22 can drive the screw rod 21 to rotate, and the rotation of the screw 21 drives the oil squeezing plate 20 to squeeze the lubricating oil, so that the lubricating oil is filled in the oil storage tank. Then, when the steering knuckle rotates, it will drive the small oiling rod 13 and the large oiling rod 14 to rotate. The rotation of the small oiling rod 13 and the large oiling rod 14 will bring out the lubricating oil and apply it on the shaft connected to the main mounting hole 11 to lubricate it. After the end, the lever 16 can be reversed. At this time, the lever 16 drives the first one-way gear 22 to rotate through the rack piece 24, and the first one-way gear 22 will not drive the screw 21 to rotate.

[0024] When the lubricating oil in the oil storage tanks of the small oiling rod 13 and the large oiling rod 14 is used up, the lever 16 can be continuously moved to allow the oil squeezing plate 20 to squeeze the lubricating oil and continue to fill the oil storage tank until the lubricating oil in the oil chamber 19 is used up, which greatly facilitates the steering knuckle lubrication process. When it is necessary to continue to add lubricating oil to the oil chamber 19, the lever 16 and the rack piece 24 need to be moved to mesh with the second one-way gear 23. At this time, moving the lever 16 sideways cannot drive the screw rod 21 to rotate through the second one-way gear 23, while moving the lever 16 in the reverse direction can drive the screw rod 21 to rotate in the reverse direction, thereby moving the oil squeezing plate 20 away from the main mounting hole 11, and then new lubricating oil can be injected into the oil chamber 19.

[0025] Obviously, the described embodiments are only a part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
