Working Principle
The king pin is a core pivot component of the vehicle's front axle steering system, connecting the steering knuckle to the front axle I-beam. Its working principle includes:
- Steering Pivot: The king pin serves as the rotation axis for the steering knuckle, allowing the wheel to pivot left and right for steering.
- Load Bearing: Withstands the vertical load at the front of the vehicle (vehicle weight and payload) as well as lateral and longitudinal forces during cornering.
- Friction Reduction: The king pin and bushings form a sliding bearing interface, lubried with grease for light, responsive steering.
- Precise Alignment: The king pin inclination directly affects caster angle, king pin inclination, and other alignment parameters for straight-line stability.
