(Heavy-Duty Truck) Axle Shaft – A core component of the axle transmission system, primarily used to transmit power from the differential to the drive wheels, enabling vehicle movement.

1. Product Positioning & Application

• Applicable Models: Mainly matches heavy-duty trucks from Sinotruk (Howo, SITRAK), Shaanxi Automobile (Delong, Aolong), FAW Jiefang (J6, J7), Foton Auman, and other brands. Also compatible with the rear axle/drive axle transmission needs of other domestic heavy-duty trucks.

• Function: Installed between the differential and the wheel hub on the rear axle (or drive axle) of heavy-duty trucks. It receives power from the differential through spline engagement and connects to the wheel hub via a flange, converting torque into driving force to propel the vehicle.

2. Appearance & Structural Features

• Material: Typically made of high-strength alloy steel (e.g., 40Cr, 42CrMo, etc.), processed through forging, quenching and tempering, and surface hardening. It offers high tensile strength, fatigue resistance, and wear resistance, suitable for heavy loads and complex road conditions (e.g., rough terrain, impacts).
