A steering knuckle that pivots on ball joints instead of a kingpin is a component typically found in modern vehicle suspension systems. Here’s a brief overview:
Steering Knuckle:
- Function: The steering knuckle is a critical component of the front suspension on vehicles, particularly in steering systems.
- Design: It connects the wheel hub or spindle to the suspension components and allows for the movement of the wheel assembly during steering maneuvers.
- Pivoting Mechanism: Instead of the traditional kingpin setup, modern steering knuckles often incorporate ball joints.
Ball Joints:
- Function: Ball joints allow for flexible movement and articulation of the steering knuckle, compensating for the changes in wheel and suspension geometry during steering and road irregularities.
- Advantages: They provide smoother movement and more precise steering control compared to older kingpin designs.
- Maintenance: Ball joints typically require periodic lubrication to ensure smooth operation and longevity.
Applications: Steering knuckles with ball joints are commonly used in various types of vehicles, including passenger cars, SUVs, and light trucks. They contribute to better handling, stability, and comfort by facilitating the controlled movement of the front wheels.
In summary, a steering knuckle pivoting on ball joints represents a modern approach to vehicle suspension design, offering improved handling dynamics and reliability compared to older kingpin-based systems.
