What Happens When a Car's Steering Knuckle Deforms?

[DeCatherine]

Deformation of a car's steering knuckle can lead to the following consequences: bearings are prone to damage, poor steering return, and abnormal noises from the vehicle body. The steering knuckle arm, commonly known as the "sheep horn," is one of the main components in a car's steering system, ensuring stable driving and sensitive transmission of the driving direction. The function of the steering knuckle is to bear the load of the front part of the car, support and drive the front wheels to rotate around the kingpin for steering. Under driving conditions, it endures variable impact loads, thus requiring high strength. The steering knuckle acts as the hinge for wheel steering, typically fork-shaped, with two coaxial holes on the upper and lower forks for installing the kingpin. The steering knuckle journal is used to mount the wheel. The two ears with pin holes on the steering knuckle are connected to the fist-shaped parts at both ends of the front axle via the kingpin, allowing the front wheels to pivot a certain angle around the kingpin for steering.
