The ball pin assembly generally includes the ball pin, ball seat, ball bowl, baffle cover and sealing cover, etc. These parts work together to ensure that the ball pin can stably and reliably transmit force and torque.

Since the steering wheels of the car have camber and toe angles, and the kingpin has caster and inclination angles, the steering rod generally moves in space when turning and the wheels bounce up and down. The ball pin, as the joint of the transmission mechanism, realizes this movement through articulation to ensure the flexibility and accuracy of the car's steering.

The ball pin needs to have a wear-resistant surface to withstand long-term friction and wear.

The core can withstand a certain strength and toughness to ensure that it is not easy to break or deform under complex working conditions.

When the ball pin assembly is connected to parts such as the control arm and steering knuckle, it must be a rigid connection to ensure strength and stiffness requirements.

All components must not slip, deform or be damaged to ensure the safety of the car.

Ball pins are widely used in the independent suspension system of automobiles. Control arms or thrust rods are often connected to other components through ball pins at the ends. In addition, ball pins are also commonly used in other mechanical structures that require hinged connections.

In order to ensure the normal use of the ball pin and extend its service life, it needs to be maintained and serviced regularly, including checking the wear of the ball pin, cleaning and lubricating the ball pin assembly, etc. If the ball pin is found to be worn or damaged, it should be replaced in time to ensure the safety of the car.
