Arocs: Transmission, gearshift - Mercedes-Benz Trucks

Power applied more effectively - automatically. Mercedes PowerShift 3.

The Arocs comes to the construction site equipped with the advanced Mercedes PowerShift 3 automated gearshift. In short: a high level of driving comfort, precise gear selection, efficient power transfer and better handling.

A tangible dynamic response, simple handling and low fuel consumption: The automated transmission ensures precise gear selection, short shift times, high driving comfort and a very high level of economic efficiency. The Mercedes PowerShift 3 applies sensitive sensor technology for gearshifting to ensure gear selection in accordance with the given driving and load situation. Overrun mode on a downhill gradient is identified and the gear is held. And the crawl function with integral manoeuvring mode makes moving off easy and manoeuvring precise and responsive. Furthermore, there are various driving modes and additional functions to make driving in construction haulage easier.

Additional functions.

With Mercedes PowerShift 3, additional functions such as direct shifting from 1 to R and reverse gears with high ratios provide for simple manoeuvring. The crawl function makes particularly easy work of moving off.

Transmissions.

Transmissions for every application.

The transmission performs fast gear changing. The generous installation space means that it is also possible to use wide gearwheels. This enables high levels of torque to be transferred.

Arocs drive programs.

offroad drive program.

The offroad driving program offers the driving modes Standard, Economy, Offroad and Manual and is optimised for the special requirements of construction-site traffic. It supports economic driving styles just as much as improved handling when pulling away or manoeuvring on building sites or when driving slowly along bad roads.

Turbo retarder clutch.

The wear-free Turbo Retarder Clutch combines the functions of a hydrodynamic start-up clutch and a primary retarder in a single component.
The engine-speed retarder supplies up to 720 kW of brake power directly from low speeds, is finely controllable via 5 levels on the steering-column lever and reduces brake wear. Designed for extreme loads, it is precisely matched to Mercedes PowerShift 3 and the electronic engine management system. This contributes to a high level of driving comfort and reduces fuel consumption in comparison to conventional torque converter solutions.
