Function:The inter-axle drive shaft is used in multi-axle drive trucks (such as 6×4, 8×4 drive forms), connecting the transfer case and the middle/rear drive axle, transmitting power and balancing the speed difference between the axles to ensure the power distribution of the vehicle under complex road conditions.

Core components:Universal joint (cross shaft): adapts to changes in transmission angle and reduces vibration.

Sliding spline: compensates for changes in wheelbase (such as when the vehicle is bumpy).

Intermediate support bearing: enhances long axis stability and prevents bending.

Flange: hard-connected to the transfer case and drive axle to ensure torque transmission.

Technical parameters (example)

Applicable torque: ≤3000 N·m (please refer to manufacturer's data for details)

Length: about 1200-1500mm (depending on the wheelbase of the vehicle model)

Balance standard: G16 level (high-speed dynamic balance ≤15g·cm)
