The English translation is as follows:

1.The automotive drive axle is an essential component in the automotive transmission system. Here are the detailed explanations of the automotive drive axle in English:

  Definition:The automotive drive axle is the shaft in the universal transmission device that can transmit power.

  It is a rotating body with high rotational speed and few supports, so dynamic balancing is crucial for its normal operation.

2.Structural Composition:The drive axle mainly consists of an axle tube, a telescopic sleeve, and a universal joint.

The axle tube is the main part of the drive axle, responsible for transmitting power.
The telescopic sleeve can automatically adjust to changes in the distance between the transmission and the drive axle to adapt to different driving conditions.
The universal joint is a key component that ensures the equal angular velocity transmission between the output shaft of the transmission and the input shaft of the drive axle, even when the two axes have a varying angle.

3.Function and Role:The main function of the drive axle is to transmit the power from the engine to the wheels, along with the transmission and drive axle, to generate driving force for the automobile.

In front-engine rear-wheel-drive vehicles, the drive axle is responsible for transmitting the rotation of the transmission to the main reducer.

4.Characteristics:The drive axle is usually made of lightweight and torsion-resistant alloy steel pipes to ensure its strength and durability.

Before leaving the factory, the drive axle undergoes a dynamic balancing test and is adjusted on a balancing machine to ensure smooth operation.

Application Fields:Special vehicle drive axles are mainly used in tankers, fuel trucks, water sprinklers, suction trucks, fire trucks, high-pressure cleaning vehicles, road wreckers, aerial work vehicles, garbage trucks, and other vehicle types.
