The axle (also called axle) is connected with the frame (or load-bearing body) by means of suspension, and the automobile tires are assembled at both ends. Its function is to transmit the force in each direction between the frame (or load-bearing body) and the tire.
The axle can be integral, just like a great barbell, and the two ends support the body with the help of the suspension system, so the integral axle generally matches with the non independent suspension; The axle can also be disconnected. For example, two umbrellas are inserted on both sides of the body, and then the body is supported by the suspension system respectively. Therefore, the disconnected axle is matched with the separate suspension.
According to different driving modes, axles are also divided into steering axle, drive axle, steering drive axle and support axle. The steering axle and support axle belong to the driven axle. Most cars use front rear drive (FR), so the front axle is used as the steering axle and the rear axle as the drive axle; The front axle of the front front drive (FF) vehicle becomes the steering drive axle, and the rear axle acts as the support axle.
