Power only makes a difference when it is applied effectively to the ground. With this in mind, on the Arocs not only all the drive components are designed for optimum power transmission - the same goes for the load-bearing structure and the chassis, too.
Arocs
Power transmission
Power only makes a difference when it is applied effectively to the ground.
More traction. In tricky situations, too.
The Arocs converts high power output into high torque, which it duly transfers to the ground virtually undiminished, thanks to the optimum coordination of all drive and chassis components. It is assisted in its work by the differential locks which can be engaged in stages and the deactivatable anti-lock braking system which provides for added safety when driving downhill in off-road terrain, for example.
Advantages at a glance.
- Virtually loss-free power transmission in the drivetrain, thanks to perfect coordination of all components
- Differential locks engageable in stages and deactivatable ABS on all-wheel-drive vehicles
- Electronic brake system with integrated auxiliary brake function, drum and/or disc brakes, hill holder
- Two different, job-matched all-wheel-drive variants
- Hydraulic Auxiliary Drive 1 for operations requiring maximum traction when high payloads are involved
- Fuel-efficient hypoid axles for on-road operation
- Precise power transfer thanks to new suspension and frame design with two different frame configurations: torsionally flexible configuration with steel suspension for off-road use; medium-rigid configuration for excellent on-road handling
- Precise, direct, light steering
- Robust planetary axles for off-road operation
All-wheel-drive range.
Two all-wheel-drive variants are available for outstanding traction: permanent all-wheel drive with low-range gear and disengageable all-wheel drive. For the majority of its work which entails demanding manoeuvres in difficult terrain, such as moving off on gradients on unsurfaced terrain, the Arocs is equipped with permanent all-wheel drive.
When high payloads and low fuel consumption are required, the engageable all-wheel drive is available.
Optimised design for optimised power transmission.
The suspension and frame are designed to ensure that the supplied power is always channelled in the right direction. Uneven surfaces are largely compensated.
The precise, direct steering enables simple manoeuvring. Two frames are available to meet the different traction requirements for the Arocs, according to the intended type of operation. One frame has a narrow frame track. Its torsional flexibility at the construction site in conjunction with steel suspension results in the best possible traction. The second frame has a wide frame track. With air suspension for road vehicles it offers optimum power transmission and excellent handling.
Electronic brake system.
For increased safety, the complex braking and traction functions of the entire integrated structure are controlled via the electronic brake system with anti-lock system and acceleration skid control. The system is based on a pneumatically operated, dual-circuit air-brake system with a constant pressure of 10 bar and is controlled by the higher-level brake control system. ABS, ASR and the auxiliary brake function are integrated.
Hydraulic Auxiliary Drive 2
Hydraulic Auxiliary Drive caters for road-oriented use with a spontaneous need for increased traction. The Hydraulic Auxiliary Drive is activated as an additional maintenance-free traction aid whenever the drive axle threatens to lose its grip.
When moving off with up to 450 bar of hydraulic pressure, the system delivers additional power to the front axle via wheel hub motors. The pressure is subsequently adjusted continuously according to the given situation.
