Key parts of the truck---Tie Rod End

What is a ball tie rod?

In the automobile suspension system, the hinge components that connect the upper and lower swing arms or connecting rods to the steering knuckle, wheel hub, etc. are called automobile ball hinge assemblies or upper and lower ball joints. Suspension ball joints are also called vertical axis ball joints.

The ball head uses a ball-type connection to realize power transmission on different axes and provides multi-angle rotation, allowing the steering mechanism to turn smoothly and reduce vibration. It can be said that the ball head is equivalent to the joint part of the car.

The function of ball head tie rod

The tie rod ball head is a tie rod with a ball head shell. The ball head of the steering spindle is placed in the ball head shell. The ball head is hinged with the edge of the shaft hole of the ball head shell through the ball head seat at its front end. The gap between the ball head seat and the steering spindle is The needle roller is embedded in the groove of the inner hole of the ball head seat, which has the characteristics of reducing the wear of the ball head and improving the tensile strength of the spindle.

The suspension ball head provides support and connection for the control arm. It can provide multi-angle rotation during steering, drive the steering mechanism to turn smoothly and reduce vibration. The multi-angle rotation function of the suspension ball head can provide lateral and longitudinal functions of the vehicle.

The composition of the ball head tie rod

Ball pin, ball seat, ball shell, ball cover, dust cover, circlip, small clamp ring, large clamp ring, etc.

How to judge whether the ball head tie rod is damaged

Different suspension ball joints have different types. Gongbo independent suspension only has steering ball joints and lower support ball joints, while multi-link suspension has upper and lower control arms and support arm ball joints.

The steering ball head can be felt by turning the steering wheel. The amount of freedom of the steering wheel is generally within 15 degrees. If it is exceeded, one person can feel the steering ball head while turning the direction and the steering tie rod moves but the horn does not move. This is It means that the steering ball head is greatly worn and needs to be replaced.

The ball joint that supports the ball joint and the control arm needs to lift the car so that the wheels are off the ground. One person can drag the tire up and down and feel if there is any slack. If the tire can move up and down easily, it means that the ball joint has a lot of slack and needs to be replaced.

Which ball head is severely worn depends on the corresponding ball head movement position. No matter which ball head is severely worn, you can feel the wheel shaking, jumping and swinging at low speeds, the steering is not sensitive, there is oil loss, and rust. Generally, you can see that the rubber sleeve of the ball head is damaged, oil leaks out, and the steering is stiff.
