First double-clutch transmission in a truck

Fuso has presented a world first with a double-clutch transmission for commercial vehicles. The new transmission drives like an automatic transmission, but unlike a fully automatic torque converter transmission, it makes for lower consumption figures and therefore lower exhaust emissions. The double-clutch transmission is an automated manual transmission. As with a fully automatic transmission it is a two-pedal system, there is an accelerator pedal, a brake pedal and a selector lever. The selector lever allows automatic or manual gearshift mode to be selected.

The M038S6 "Duonic transmission" has six forward gears and a reverse gear. The P-function ensures safe parking by preventing the vehicle from rolling away. "Duonic" features a non-wearing wet clutch, which lowers maintenance costs by eliminating the need to replace worn clutch discs. A creep function has been added to the wet clutch, as is usual for automatic transmission with a torque converter. This enables the vehicle's speed to be easily controlled when moving slowly - for example when manoeuvring or in stop-and-go traffic - and hill-starts are also made easier.
