as shown in fig. 1 to 3, the utility model discloses a tie rod ball assembly with a lubricating function, which comprises a ball pin 1 and a ball seat 2, wherein the lower end of the ball pin 1 is provided with a ball head 11, the ball head 11 is movably arranged in the ball seat 2, a corresponding installation cavity 21 for installing the ball head 11 is arranged in the ball seat 2, a ball bowl 3 positioned below the ball head 11 is arranged in the installation cavity 21, meanwhile, a lubricating oil storage cavity 22 and two oil guide pipelines 23 are arranged in the ball seat 2, the lubricating oil storage cavity 22 is positioned below the installation cavity 21, and the oil guide pipelines 23 are used for communicating the lubricating oil storage cavity 22 with the installation cavity 21, and the specific method comprises the following steps: both oil guide pipes start from the lower end of the oil storage chamber 22, and one of them extends above the ball bowl 3 and the other extends to the bottom of the installation chamber 21. In addition, an elastic compression mechanism is provided in the lubricant storage chamber 22, a driving mechanism for driving the elastic compression mechanism to elastically compress the lubricant storage chamber 22 is provided on the ball head 11, and finally, a lubricant return mechanism for cooperating with the elastic compression mechanism is provided in the lubricant storage chamber 22.
The working principle of the structure is as follows: when a driver rotates the steering wheel, the ball stud 1 drives the ball head 11 to rotate in the ball seat 2, when the ball head 11 rotates, the ball head 11 can enable the driving mechanism to drive the elastic compression mechanism to adjust the size of the oil storage space in the lubricating oil storage cavity 22, when the oil storage space in the lubricating oil storage cavity 22 becomes smaller, lubricating oil can flow out of the oil guide pipeline 23 to lubricate the upper end and the lower end of the ball head 11, meanwhile, the ball head 11 can also cover the ball head 11 comprehensively in the rotating process, and when the oil storage space in the lubricating oil storage cavity 22 becomes larger, some redundant lubricating oil can flow back into the lubricating oil storage cavity 22 from the oil guide pipeline 23 and be absorbed by the lubricating oil guide mechanism, so that lubricating oil is prevented from leaving the lubricating oil storage cavity 22 in the bumping process of a vehicle.
The specific implementation scheme is as follows: the elastic compression mechanism specifically includes a movable plate 41 and an elastic expansion member 42, wherein the movable plate 41 is disposed in the lubricant storage cavity 22 in a vertically sliding manner, a sealing ring 43 is disposed between the movable plate 41 and the lubricant storage cavity 22, and the elastic expansion member 42 is disposed below the movable plate 41 and abuts against the space between the movable plate 41 and the lubricant storage cavity 22, and in this embodiment, the elastic expansion member 42 is a spring.
