Description

The Structure and Function of Automotive Steering Knuckles: The “Joint” of the Steering System

The automobile steering knuckle (or steering pivot) is a core component of the steering axle, featuring a complex structure and diverse functions. It connects to the vehicle frame via the kingpin, forming a steering hinge; at the same time, it houses the wheel hub bearing through its journal, ensuring that the wheels can rotate flexibly around the kingpin. During driving, the steering knuckle must withstand multidirectional impact loads from the road surface—including lateral steering forces, longitudinal braking forces, and vertical vibrations—thus its design must strike a balance between high strength, high rigidity, and lightweight construction.

Take the Tesla Model Y as an example: its integrated die-cast underbody combines what would traditionally require 700 to 800 weld points into a single die-cast component. The “sheep’s horn” feature serves as a critical structural node. By optimizing its structural design and material selection, this component achieves a 30% weight reduction while simultaneously improving fatigue resistance by 20%. This design not only reduces unsprung mass (thereby enhancing handling responsiveness) but also strengthens the overall structural integrity by minimizing connection points.
