The material of a car steering knuckle is medium-carbon low-alloy steel.
Considering the working conditions and importance of the car steering knuckle, the material generally uses medium-carbon low-alloy steel, commonly 42CrMo square or round hot-rolled steel, or materials equivalent to 42CrMo, although there are a few exceptions.
The steering knuckle, also known as the "steering knuckle arm," is the axle end at both ends of the front I-beam that bears the steering function. It somewhat resembles a ram's horn, hence the common name "ram's horn." The steering knuckle is one of the important components of the car steering axle, enabling stable driving and sensitive transmission of driving direction. The function of the steering knuckle is to transmit and bear the load of the front of the car, supporting and driving the front wheels to rotate around the kingpin, thus steering the car. Under driving conditions, it bears varying impact loads; therefore, it requires high strength.
The steering knuckle is one of the main components of a car's steering axle. It enables the car to travel stably and transmit direction sensitively. The function of the steering knuckle is to bear the load of the front of the car, support and drive the front wheels to rotate around the kingpin to steer the car. When the car is in motion, it is subjected to varying impact loads, therefore, it is required to have high strength.
