Description

Technical Field

[0001] This utility model relates to the field of tie rod technology, and in particular to a ball joint type heavy-duty tie rod assembly. Background Technology

[0002] Ball joint heavy-duty tie rod assembly is a key component used in heavy machinery or vehicles. During vehicle steering, the rotation of the steering wheel is transmitted to the steering tie rod assembly through the steering gear. The ball joint allows the tie rod to rotate flexibly in different directions, enabling the wheels to steer according to the driver's intention, thereby achieving vehicle steering control and ensuring the accuracy of the driving direction.

[0003] Currently, ball joint heavy-duty tie rod assemblies mostly use manual periodic lubrication, injecting lubricating oil into the ball joint using a grease gun. This method not only consumes a lot of manpower and time, but also makes it difficult to accurately control the amount of oil injected. In mining machinery, heavy trucks and other equipment, due to the harsh working environment and frequent vibration, grease is easily lost, requiring frequent maintenance and lubrication, which greatly increases the equipment's operation and maintenance costs and downtime. Moreover, during manual lubrication, excessive oil is often injected in order to ensure lubrication effect. The excess grease not only overflows, causing resource waste, but also attracts dust and impurities, forming oil stains that contaminate the equipment and working environment.

[0004] Therefore, it is necessary to invent a ball joint heavy-duty tie rod assembly to solve the above problems. Utility Model Content
