[0002] The chassis cross tie rod, also known as a transverse stabilizer bar or roll bar, is an auxiliary elastic element in an automobile suspension system. When the automobile turns, the body will incline, at which time the transverse stabilizer bar will be twisted and deformed, resisting the lifting of the wheels through its elastic force to keep the body as balanced as possible and prevent excessive lateral inclination of the body when turning and the automobile from tipping over laterally.

[0003] If the automobile suspension system is not maintained in a timely manner, such as oil leakage of shock absorbers and aging of springs, the tie rod may be damaged over a long period of time. If the tie rod is not well protected against corrosion and is used in a humid or salt spray environment for a long time, the tie rod may be corroded and damaged, thereby affecting the service life of the chassis cross tie rod. In the event of a sharp turn or sudden braking, the chassis cross tie rod cannot effectively absorb the shock, which may cause excessive stress on the suspension system and damage the tie rod, affecting the overall driving experience and safety of the automobile.
