[0006] In the above-mentioned wear-resistant steering tie rod ball head, an oil storage tank is provided in the limit block, an oil injection pipeline is provided on the limit block, a plug is provided on the oil injection pipeline, and an oil delivery pipeline is provided between the lubrication groove and the oil storage tank.

[0007] In the above-mentioned wear-resistant steering tie rod ball head, a plurality of reinforcing ribs are arranged between the ball head housing and the tie rod.

[0008] In the above-mentioned wear-resistant steering tie rod ball head, the limiting portion and the limiting block are integrally arranged, and the limiting portion is arranged in an arc.

[0009] In the above-mentioned wear-resistant steering tie rod ball head, the ball head housing and the tie rod are integrally arranged, and a fixing nut is arranged on the ball pin.

[0010] Compared with the prior art, the utility model is provided with a lubrication groove and a ball. When the ball head is working, the original sliding friction can be converted into rolling friction through the ball, thereby reducing the friction force. In the process of the ball rolling, the lubricant in the lubrication groove will be brought out to automatically lubricate the ball head to further reduce the friction force and increase the service life. The shock absorbing component can reduce the impact force generated by the ball head during operation and increase the overall service life of the ball head. BRIEF DESCRIPTION OF THE DRAWINGS
