The Sitrak Driveshaft is a critical powertrain component engineered to reliably transmit torque from the transmission to the rear axle in Sinotruk Sitrak trucks. Designed for a specific configuration with a C5H MC07 rear PTO, a wheelbase of 1800+3050+1350 mm, and an HW19710 transmission, this assembly ensures efficient power delivery under heavy loads. As a high-precision part within the extensive catalog of Sinotruk Sitrak parts, it is built from high-strength materials to withstand torsional stress, vibration, and harsh operating conditions.
The Sitrak Driveshaft, also known as a propeller shaft, is a tubular steel component that connects the transmission output shaft to the differential input pinion, enabling power transfer in rear-wheel-drive or all-wheel-drive trucks. This specific assembly is designed for a multi-piece configuration, including a main driveshaft and an intermediate shaft, to accommodate the long wheelbase (1800+3050+1350 mm) and the presence of a rear Power Take-Off (PTO). It incorporates precision-balanced tubes, universal joints (U-joints) for angular flexibility, and flanged yoke connections.
Functionally, the Sitrak Driveshaft transmits rotational force (torque) from the gearbox to the driving axle. The universal joints at each end allow the shaft to operate at variable angles, ensuring smooth power delivery even when the connected components are not perfectly aligned. The intermediate shaft, supported by a center bearing assembly, provides additional length and stability for extended wheelbase vehicles, reducing harmonic vibrations and preventing shaft whip. The assembly uses high-grade fasteners, such as serrated flange bolts and nuts, to secure the shaft to the companion flanges, ensuring a rigid and reliable connection.
Applications of this specific Sitrak Driveshaft assembly are primarily in Sinotruk C5H model trucks equipped with the MC07 engine, rear PTO unit, HW19710 transmission, and the exact three-segment wheelbase (total 6200 mm). This configuration is common in vocational trucks used for applications requiring auxiliary power, such as dump trucks, concrete mixers, and refuse collectors.
Technical specifications of the Sitrak Driveshaft include the use of seamless steel tubing for high torsional strength, precision-welded yokes, and balanced assemblies to minimize NVH (Noise, Vibration, and Harshness). The universal joints are typically of the cross and bearing type, packed with high-temperature grease.
