According to the structure of the axle, it can be divided into two types: integral and disconnected.
Integral axle: Also called non-disconnected axle, its axle shaft casing and main reducer shell are rigidly connected with the peripheral shell to form an integral beam.
The integral axle housing has been widely used because of its good strength and stiffness performance, which facilitates the installation, adjustment and maintenance of the main reducer. Integral axle housings can be divided into monolithic casting, mid-section cast-in steel pipe, and steel plate stamping and welding due to different manufacturing methods.
Disconnected axle: generally matched with independent suspension, it is more common in cars, trucks are generally only used by military trucks, and not common in civilian trucks.
