What are the Parts of the Car Axle?

The axle (also called the axle) is connected to the frame (or load-carrying body) by means of a suspension, with wheels mounted on both ends. In addition, it is worth noting that the subframe can be regarded as the skeleton of the front and rear axles, and is an integral part of the front and rear axles. The subframe is not a complete frame, but a bracket that supports the front and rear axles and suspension.

The function of the axle is to bear the load of the car and maintain normal driving of the car on the road. It is the suspension, not the axle, that transmits forces and moments between the frame and the wheels. According to different driving methods, the axles are also divided into four types: steering axle, drive axle, steering drive axle and support axle. In general cars, the front axle is responsible for the steering task, and the front and rear axles of a four-wheel steered vehicle are all steering axles.

A transaxle is a mechanism that takes the rotational speed and torque from the transmission and transmits them to the drive wheels. The steering drive axle refers to a mechanism that not only undertakes the steering task but also transmits power to the driving wheels. The supporting axle refers to a mechanism that neither undertakes the task of steering nor transmits power to the driving wheels. For front-wheel drive vehicles, the front axle is a steering drive axle, and the rear axle is a support axle; for a front-rear drive vehicle, the front axle is a steering axle, and the rear axle is a drive axle.

The most likely faults of the axle are deformation and fracture, as well as some faults caused by displacement wear. So be careful driving.
