The steering ball head sealing structure comprises an outer connecting rod, a ball head pin and a joint arm, wherein a ball socket is arranged at the end part of the outer connecting rod, the ball head pin consists of a ball head and a pin rod, the ball head is assembled in the ball socket, one end of the pin rod is connected with the ball head, the middle part of the pin rod is connected with the joint arm, and the end part of the other end of the pin rod is in threaded connection with a nut; a dust cover is arranged between the ball socket and the joint arm, and the pin rod penetrates through the middle of the dust cover.
Further, the upper end face of the dust cover is of an annular structure, an outer sealing rib is arranged at the outer edge of the annular structure, an inner sealing rib is arranged at the inner edge of the annular structure, and oil storage grooves are formed in the inner sealing rib and the outer sealing rib; the inner wall of the upper opening of the dust cover is provided with a first wave folding part, and the inner wall of the lower opening of the dust cover is provided with a second wave folding part.
Further, the height of the outer sealing rib is higher than that of the inner sealing rib, and the top of the outer sealing rib is a plane.
The beneficial effects of the utility model are as follows:
the novel steering ball head sealing structure is designed, and the dust cover is structurally improved, so that the dust cover has a better oil seal sealing effect. And design the ripples portion to the opening of dust cover, the ripple structure both can be better sealed, also laminating bulb round pin pole that also can be better reduces the wearing and tearing of bulb round pin to the dust cover when rotating. The service life of the whole equipment is greatly prolonged.

FIG. 1 is a schematic diagram of the structure of the present utility model;
FIG. 2 is a schematic view of a portion of the ball stud of the present utility model;
figure 3 is a partial cross-sectional view of a dust cap of the present utility model.
The ball joint comprises an outer connecting rod 1, a ball stud 2, a joint arm 3, a ball socket 4, a ball head 5, a pin rod 6, a nut 7, a dust cover 8, an outer sealing rib 9, an inner sealing rib 10, an oil storage groove 11, a first wave folding part 12 and a second wave folding part 13.
Detailed Description
Referring to fig. 1 and 2, a steering ball sealing structure comprises an outer connecting rod 1, a ball pin 2 and a knuckle arm 3, wherein a ball socket 4 is arranged at the end part of the outer connecting rod 1, the ball pin 2 consists of a ball 5 and a pin rod 6, the ball 5 is assembled in the ball socket 4, one end of the pin rod 6 is connected with the ball 5, the middle part of the pin rod 6 is connected with the knuckle arm 3, and the end part of the other end is in threaded connection with a nut 7; a dust cover 8 is arranged between the ball socket 4 and the knuckle arm 3, and the pin rod 6 passes through the middle part of the dust cover 8.
Referring to fig. 3, the upper end surface of the dust cover 8 has an annular structure, an outer sealing rib 9 is arranged at the annular outer edge, an inner sealing rib 10 is arranged at the annular inner edge, and oil storage grooves 11 are arranged on the inner sealing rib 10 and the outer sealing rib 9; the inner wall of the upper opening of the dust cover 8 is provided with a first wave folding part 12, and the inner wall of the lower opening of the dust cover 8 is provided with a second wave folding part 13. The height of the outer sealing rib 9 is higher than that of the inner sealing rib 10, and the top of the outer sealing rib 9 is a plane.
The upper end face of the dust cover 8 is provided with an outer sealing rib 9 and an inner sealing rib 10, the upper end face of the outer sealing rib 9 is a plane, and the outer sealing rib is in contact with the knuckle arm to play a sealing role. An oil storage groove 11 is additionally arranged between the inner sealing rib 10 and the outer sealing rib 9 and is used for filling grease for oil sealing. Because the upper end of the pin rod 6 is provided with the nut 7, under normal assembly, the nut 7 needs to be pressed down to lock, and meanwhile, the knuckle arm on the pin rod 6 is pressed down. The height of the outer sealing rib 9 is higher than that of the inner sealing rib 10, the knuckle arm 3 firstly contacts the outer sealing rib 9, and the height of the outer sealing rib 9 is reduced by slight deformation. The arm 3 is depressed to the inner seal bead 10 where the threads are assembled in place and the arm is no longer depressed. The outer sealing rib 9, the oil storage groove 11, the inner sealing rib 10 and the knuckle arm 3 form an oil seal.
The inner wall of the upper opening of the dust cover 8 is provided with a first wave folding part 12, and the wave folding bulges of the first wave folding part 12 can block grease and dust. Because the pin rod 6 is generally of a round table-shaped structure with a thin upper part and a thick lower part, the contact surface of the pin rod 6 and the upper opening of the dust cover 8 is not vertical, the upper opening can be slightly deformed by the wave folding recess of the first wave folding part 12, the pin rod is more attached to the shape of the pin rod, the sealing effect is better, and the abrasion is lower. The second folded portion 13 of the lower opening inner wall is the same.
Although the present utility model has been described with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described, or equivalents may be substituted for elements thereof, and any modifications, equivalents, improvements and changes may be made without departing from the spirit and principles of the present utility model.
