Product Description
Automobile lower ball joint is an important part of suspension system, which is located between the control arm and the steering knuckle, and plays the role of connecting and transmitting power. The lower ball head is usually made of metal, which has strength and durability.
The function of the lower ball head is as follows:
1. Connecting the control arm and the steering knuckle: The lower ball joint connects the control arm and the steering knuckle through threads to firmly fix them together. This connection mode can bear the force and torque from the suspension system and steering system, and ensure the stable connection between them.
2. Transmission of force and torque: As a connector between the suspension system and the steering system, the lower ball head can transmit the steering force from the steering system and the suspension force from the suspension system. It can effectively transfer these forces and torques to the control arm and steering knuckle, so that they can work together to realize the steering and suspension movement of the wheel.
3. Provide steering flexibility: The design of the lower ball joint enables the steering knuckle to rotate freely within a certain range, thus realizing the steering of the wheel. The flexibility and rotatability of the lower ball head can make the steering system more sensitive and accurate, and provide good maneuverability and steering response.
4. Reduce friction and wear: The lower ball head usually has a lubricating device, which can reduce the friction between the ball head and the control arm and steering knuckle, and reduce wear and energy loss. This is helpful to prolong the service life of the lower ball head and improve the efficiency and reliability of the suspension system and steering system.
5. Adjust the suspension geometry: The design and installation position of the lower ball head can affect the geometric characteristics of the suspension system, such as wheel inclination, toe angle and toe-in angle. By adjusting the position and angle of the lower ball head, the suspension system can be adjusted and calibrated to meet different driving needs and road conditions.
To sum up, the automobile lower ball joint, as a connector between the suspension system and the steering system, has the functions of connecting and transmitting power, providing steering flexibility, reducing friction and wear, and adjusting suspension geometry. It plays a vital role in the suspension and steering system of the automobile, ensuring the stability, handling and driving safety of the vehicle.
