From the engine to the axles – all drive components on the Arocs have been developed for the very best performance. Also in terms of robustness.
Arocs
Load capacity, drivetrain
From the engine to the axles.
Strong links, strong chain.
Extended service life.
In order to meet the high requirements which apply in construction haulage, a particularly stringent benchmark was applied from the outset in the development and design of the Arocs: practical reality. All drive components of the Arocs offer a particularly robust, durable design, a high degree of reliability and an increased service life.
Full braking power.
Depending on the intended application, drum brakes, a combination of disc and drum brakes or disc brakes ensure short stopping distances for the Arocs.
Advantages at a glance.
- 6-cylinder in-line engine in particularly robust design with extended service life
- Broad torque curve reduces number of shift operations and saves wear on clutch and transmission
- Clutches for maximum torque of up to 3000 Nm
- Turbo retarder clutch for wear-free moving off and manoeuvring and wear-free braking at high gross permissible combination weights and high levels of torque
- Transmission and gearshift with extended component service lives
- Robust planetary axles with load-bearing capacity of up to 16 t for off-road use
- Weight-optimised, fuel-saving hypoid drive axles with maximum axle load of 13 t
- Highly robust drum and/or disc brakes, optimised for on- and off-road use
Engines.
Durable engines.
A particular hallmark of the 6-cylinder in-line engines is their robustness. This is ensured by one-piece steel pistons, reinforced conrods and bearings and the more rigidly designed crankcase, for example. The wider torque curve reduces the number of gearshift operations and thus lowers the load on the clutch and transmission.
Clutch.
The clutches are equipped with overload protection and a warning system, and enable the transfer of torque levels of up to 2600 Nm.
The wear-free turbo retarder clutch offers maximum stability when moving off and manoeuvring with very high gross combination weights and torque levels. It also serves as a primary retarder, thus providing for additionally enhanced safety.
Gearboxes.
One contributory factor to the robustness of the transmission and gearshift is the ceramic printed-circuit board of the transmission control system, for example, boasting high resistance to thermal and vibration-induced stress. The transmission oil cooler155 reduces thermal stress, rendering the transmission more robust in daily operations.
Axles.
The planetary axle implies a load capacity of up to 16 t, though the Arocs can also be fitted with hypoid drive axles with a load capacity of up to 13 t.
