The axle is an essential part of the vehicle. It plays the role of bearing the vehicle load, maintaining the vehicle running and providing vehicle braking. It is generally connected with the frame or body through the suspension, and both ends are used to install wheels. According to different models and different use requirements, the axle can also be divided into many kinds. If you only look at the structural form, it can be divided into integral type and disconnected type.

The integral axle is easier to understand. Most of the axles we see usually belong to the integral axle, and the wheels at both ends are connected and fixed together by an axle beam in the middle. What kind of axle is a disconnect axle?

The disconnected axle is relative to the integral axle. The wheels at both ends are connected in the middle of the articulated structure, which can realize relative movement by connecting them under the frame through the suspension. Generally speaking, the two wheels of the disconnected axle can move up and down without affecting each other, which is mainly due to the independent suspension of the two wheels.

From this point of view, the use of disconnected axle can effectively improve the ground clearance of the vehicle body, reduce the bumps and vibrations on the vehicle body, and improve the comfort of drivers and passengers.

In addition, because there is no axle beam connection in the middle of the disconnected axle, the position of the engine can also be reduced or moved forward to a certain extent, so as to reduce the center of gravity of the vehicle and improve driving stability.

Therefore, the split axle is more suitable for complex, harsh and high vehicle trafficability road conditions, such as military vehicles, off-road vehicles, etc.

What about the load-bearing capacity of the disconnected axle? Because the two wheels of the disconnected axle are articulated connecting structure, its load-bearing performance can not compare with the hollow or solid axle beam of the integral axle to a certain extent. Therefore, in many freight vehicles, such as semi-trailer, which is widely used at present, the integral axle is used.

Compared with the split axle, the design of the integral axle is simpler and can provide greater load and torque. In addition, because its half axle and other components operate in the sealed axle beam, it is easier for daily maintenance and repair. Even in terms of modification, it is much simpler than the disconnected axle.

Darong axle is a professional manufacturer of semi-trailer axle in China. Up to now, it has accumulated 20 years of R & D and production experience. Its disc axle, drum axle, low flat axle, three line six axle axle, concave axle and special axle are only used. From the classification point of view, they all belong to the integral support axle. The use of "one-piece" axle casting technology has greatly improved the bearing performance of the axle and is specially built for heavy-duty transportation vehicles, With stable quality and affordable price, it is a typical representative of domestic cost-effective axle.
