Front Axle Model of a Car

The front axle (also known as the front beam) consists of three parts: the steering knuckle and the hub. The front axle assembly also utilizes the pivoting of the steering knuckle to achieve vehicle steering, and is therefore also referred to as the steering axle. This assembly is located at the front of the vehicle, thus it is also called the front axle. In addition to bearing the weight of the vehicle, the front axle assembly also bears the vertical load between the ground and the vehicle frame, the braking force, the lateral force, and the bending moment caused by the lateral force, among others.
