Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to a balancing rod ball head used for stabilizing a vehicle body. Background Art

[0002] The main function of the stabilizer bar ball head is to connect the suspension and the stabilizer bar joint, which mainly plays the role of transmitting the force between the car suspension and the stabilizer bar, making the car more comfortable and natural during driving. When the left and right wheels pass through the same road bumps or holes, the stabilizer bar will not work. However, if the left and right wheels pass through different road bumps, that is, the horizontal heights of the left and right wheels are different, the rod body will be twisted to produce anti-roll resistance, thereby playing a balancing role.

[0003] In the prior art, since the lubricating oil on the ball head and the ball seat is limited, the lubricating oil will gradually evaporate and decrease after long-term movement of the ball head, so wear is easy to occur between the ball head and the ball seat. Usually, lubricating oil is added to the ball head after the ball head makes an abnormal noise.

[0004] However, the ball head assembly needs to be disassembled before lubricating oil can be dripped between the ball head and the ball seat, and lubricating oil may need to be added multiple times for lubrication in a short period of time, which is very inconvenient. Utility Model Content
