SCANIA, at the Elmia fair in Sweden, has introduced the G38, the latest addition to its G-series gearboxes designed for Scania Opticruise. This robust gearbox is specifically engineered to complement Scania’s most powerful V8 engine, the 770 hp powerhouse. The combination promises benefits such as fuel and weight savings, a smoother ride, and improved starting.

The G38 is tailor-made to handle the immense torque generated by the 770 hp V8 engine, capable of managing up to 3,800 Nm. Remarkably, it achieves this without any increase in weight or dimensions compared to its predecessor, the G33. This feat is attributed to advancements in metallurgy, utilizing stronger steel qualities and techniques like cog polishing and shot peening.

The G-series gearboxes, including the G38, are known for being lighter and quieter than their predecessors, contributing to fuel savings and compliance with future noise regulations. They utilize pneumatic actuators for gearshifts and shaft brakes to reduce the need for synchronizations, allowing for wider cogs and improved performance.

According to Bo Eriksson, Product Manager at Scania Trucks, the G-series gearboxes offer a range of customer benefits, including flexibility and suitability for various applications requiring substantial horsepower and torque. Heavy-haulage tractors, in particular, are expected to gain significantly from the G38.

The G38 is also available in a Heavy Duty (HD) version, the G38CH, featuring a wider planetary gear wheel for enhanced robustness in demanding off-road conditions.

Compared to the current common gearbox for similar operations, the G38 is shorter and has only one built-in torque limitation, ensuring a smooth driving experience. It offers 14 forward gears, including a super crawler and a direct gear, and the option for up to 8 reverse gears.

Scania’s introduction of the G38 gearbox at the Elmia fair demonstrates its commitment to innovation and providing solutions that meet the evolving needs of the transport industry.

The G38’s combination of power, efficiency, and versatility makes it a valuable addition to Scania’s gearbox lineup, particularly for heavy-duty applications.
