[0002] The suspension ball joint is used to connect the car's steering gear and steering wheel. It is one of the key accessories of the car's steering system. The quality and performance of the suspension ball joint directly affect the stability and safety of the car's driving. Today, in order to solve the problem of large wear of the ball joint, a protective cover is usually added to prevent dust from entering, thereby reducing its wear. Lubricating oil is also added to the friction of the ball joint to reduce its friction and thus reduce its wear. However, the lubricating oil will be consumed faster and cannot be lubricated continuously for a long time, which makes the ball joint easy to be quickly worn and consumed, reducing its service life.

[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 Figure 1-5, a wear-resistant suspension ball head includes a ball head seat 10, a ball head rod 11 and a ball head cover 12, a connecting rod is fixed on the outer peripheral side of the ball head seat 10, the ball head rod 11 is detachably installed in the ball head seat 10, the ball head cover 12 is sleeved on the outer peripheral side of the ball head rod 11, and the ball head cover 12 is also installed on the ball head seat 10, the ball head cover 12 is divided into a corrugated part and a buckle part, wherein the material of the corrugated part can be one of rubber and resin, and the cross section of the buckle part is L-shaped, and a convex block is provided thereon, the buckle part is an open loop, and the two ends of the open loop are fixed with mounting rods 25, through the open loop ball head cover 12, the ball head cover 12 is more convenient and quick when installing and removing, and a lubrication component is provided in the ball head seat 10;

[0021] The lubrication assembly includes a pressure plate 13 sliding in the ball head seat 10 and at least two slide rods 14, wherein the pressure plate 13 is arranged in an annular shape and is connected to the ball head seat 10 through a plurality of pressure plate springs 24. The abutment of the pressure plate 13 and the protrusion block can prevent the ball head cover 12 from falling off easily when the ball head rotates. The slide rod 14 is connected to the ball head seat 10 through the slide rod spring 22. Three through holes are opened in each slide rod 14. The pressure plate 13 abuts against the slide rod 14, and the through holes are staggered to open the opening, so that the lubricating oil intermittently enters the ball head.

[0022] A spherical cavity is provided in the ball head seat 10, and the ball head rod 11 is located in the spherical cavity. A pressure plate cavity 26 is also provided on the inner wall of the spherical cavity. The pressure plate 13 is located in the pressure plate cavity 26, and part of the pressure plate 13 extends into the spherical cavity. At least two slide rod cavities 19 are provided in the ball head seat 10, and the slide rod cavity 19 passes through the pressure plate cavity 26. The slide rod 14 is located in the slide rod cavity 19, and three main connecting holes 20 are provided between the slide rod cavity 19 and the spherical cavity. An oil storage cavity 18 is also provided in the ball head seat 10, and the oil storage cavity 18 includes a pin part and a main body part, wherein the pin part is located on the outer peripheral side of the slide rod cavity 19, and three secondary connecting holes 21 are provided between the pin part and the slide rod cavity 19, and the three secondary connecting holes 21 are staggered with the three main connecting holes 20, and the slide rod 14 is staggered through the main connecting holes 20 and the secondary connecting holes 21. The through hole on 14 is first connected with the secondary connecting hole 21 to store the hydraulic oil in the through hole, and then connected with the main connecting hole 20 to allow the hydraulic oil to flow out. At the same time, the secondary connecting hole 21 is also closed to prevent the lubricating oil from leaking or being used quickly, thereby greatly extending the total lubrication time of the ball head and reducing the wear of the ball head. An extrusion plate 16 is slidably provided in the main part of the oil storage chamber 18, and a force storage screw block 15 is threadedly connected to the side of the ball head seat 10 away from the ball head rod 11. The center of the force storage screw block 15 is hollow, and a sealing block 17 is installed in the hollow. The force storage screw block 15 and the extrusion plate 16 are connected together by a force storage spring 23, and the force storage screw block 15 and the extrusion plate 16 are slidably connected. Through the extrusion of the force storage spring 23 and the extrusion plate 16, the lubricating oil in the oil storage chamber 18 can be gradually squeezed out.

[0023] When in use, it is necessary to remove the sealing block 17, unscrew the force storage screw block 15, and under the elastic force of the force storage spring 23, the extrusion plate 16 is located on the side of the oil storage chamber 18 close to the force storage screw block 15, and then the lubricating oil is injected into the oil storage chamber 18 from the hollow part of the force storage screw block 15, and then the sealing block 17 is installed, and the force storage spring 23 is squeezed to screw the force storage screw block 15 onto the ball head seat 10. At this time, since the oil storage chamber 18 is filled with lubricating oil, the force storage spring 23 is in a compressed force storage state, and the ball head cover 12 is installed after the ball head is inserted.

[0024] When installing the ball head sleeve 12, first pinch the two mounting rods 25 inward to make the mounting part of the ball head sleeve 12 form a complete ring. The diameter of this ring should be smaller than the diameter of the mounting part of the ball head sleeve 12 in the normal state. At this time, the ball head sleeve 12 can enter the ball head cavity of the ball head seat 10, and then abut the mounting part of the ball head sleeve 12 against the pressure plate 13, so that the pressure plate 13 squeezes the pressure plate spring 24 and moves toward the direction close to the slide rod 14, and then loosen the mounting rod 25. At this time, the ball head sleeve 12 itself has elasticity, so that it returns to an open-loop state. At this time, the raised part of the ball head sleeve 12 can enter the slide rod cavity 19 under the abutment of the pressure plate 13 and the pressure plate spring 24, and then be stuck by the pressure plate spring 24.

[0025] When the ball head is in use, it will rotate in the ball head cavity. When the ball head rod 11 rotates, the corrugated part of the ball head sleeve 12 will be squeezed, so that the pressure plate 13 here will also be squeezed on the squeezed side of the ball head sleeve 12, so that the pressure plate 13 will abut on the slide bar 14, thereby driving the slide bar 14 to squeeze the slide bar spring 22 and slide in the direction away from the pressure plate 13 until the through hole on the slide bar 14 is connected with the secondary connecting hole 21. At this time, the hydraulic oil in the oil storage cavity 18 will enter the through hole of the slide bar 14. When the ball head is reset, the pressure plate 13 will abut against the ball head sleeve 12 and reset under the elastic force of the pressure plate spring 24. At this time, the slide bar 14 is also reset under the elastic force of 2. At this time, the through hole of the slide bar 14 is connected with the main connecting hole 20, and then the hydraulic oil in the through hole will flow from the main connecting hole 20 into the ball head cavity to lubricate the ball head, thereby achieving the purpose of reducing its wear.

[0026] 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.
