The new Scania gearbox is a heavy-duty hero.
Scania’s new Heavy Planetary Gearbox equips the Scania Super engine for the toughest mining and off-road environments, combining higher torque management, lower fuel consumption and longer service life. The ground-breaking new heavy-duty gearbox for the Scania Super engine is the result of a decade’s worth of blood, sweat and gears. Three years of computer simulations even before the first prototype. Thousands of hours at the Scania test track. Months of tough field tests in daily mining operations. Weeks spent analysing performance data. And scores of hardware and software iterations in response to customer feedback. But it was all worth it. The new Scania Heavy Planetary gearbox is powerful enough for the most demanding construction, heavy haulage, agriculture, heavy forestry and mining jobs, yet lighter and smaller than the previous gearbox generation.

Developing a completely new gearbox range is a huge undertaking, especially when you are set to outperform what is already an industry benchmark. That is why the new Scania Opticruise gearbox range has no parts in common with the existing range. With its wealth of performance enhancements, it will stay com¬pet¬i¬tive throughout this decade. Scania has a longstanding tradition of offering powertrains with low-revs and high torque as key elements for achieving low fuel consumption. Why? If the engine has the torque and stamina to propel the truck at low engine speeds, less fuel is used (simply since fuel needs to be injected in a cylinder on every fourth piston stroke).
In practise, it entails highly complex computations with a multitude of factors to consider, but that nail the core of it. If a favourable cruising speed can be maintained at around, or just above, 1050 engine revolutions per minute, fuel will definitely be saved. Just until recently, a typical long-distance truck operated on a 1400 rev-per-minute-level. Scania’s new gearbox range has a significantly wider spread with a true overdrive gear on top and can handle both low and high revs in an efficient way.
Scania’s engineers adopted a new approach to reversing. In most gearboxes, going in reverse entails letting a separate cog wheel rotate the mainshaft in the opposite direction. In the new Scania range, by contrast, the planetary engagement at the output shaft is used instead, and reversing is effectuated by locking up the planetary wheel carrier. This solution allows having eight gears for going in reverse at speeds up to 54 km/h (optional). This is useful when, for instance, tipper trucks need to go in reverse for long dist¬ances (such as at tunnel construction sites).The oil change intervals have been greatly improved, due to higher precision and the use of bigger oil filters and high-quality oil.
Clever PTO solutions
No truck gearbox range would be worth mentioning without also citing its PTO (Power Take-Off) capabilities. Scania’s new range comes with an abundance of newly developed and clever PTO solutions aiming to fulfil any number of advanced PTO needs asked for by Scania’s customers, regardless of their application.
A whole range, in fact nine different PTOs, will be available, characterised by in-creased per¬formance, less drag losses and great flexibility via modularity. The EG PTOs are driven directly by the layshaft and are pressure-lubricated by the gearbox. The new interface on the gearbox with a lubrication port means that they can power heavier equipment such as hydraulic pumps. The EK PTO’s (flywheel driven) will consist of a separate unit, mounted between the engine and the gearbox. Four different ratios will be available and the output tower is possible to mount in three different positions. “All-in-all, we have every reason to believe that our new gearbox range is state-of- the-art for powerful truck engines,” says Alexander Vlaskamp, Executive Vice President, Head of Sales and Marketing at Scania. “We hope it will support our customers in fulfilling their transportation tasks in a seamless and sustainable way for many years to come”.
