Additional traction on critical surfaces.Whenever additional traction is needed on slippery or unpaved surfaces, MAN HydroDrive® front-axle drive can be engaged. It consists of hydrostatic wheel hub motors, which generate torque on the front wheels and thus drive them when required.
The driver decides for themselves whether HydroDrive® should provide additional power automatically or if they want to switch the system on whenever additional traction is required.With MAN HydroDrive®, a hydropump on the gearbox output supplies the wheel hub drives at the front axle.
This ingeniously simple, robust and maintenance-friendly technology is comparable with the conventional rear-axle drive in terms of fuel consumption and wear, and offers a range of advantages over the classic all-wheel drive. The distributor gearbox, a typical feature of the classic all-wheel drive, is no longer required where hydrostatic wheel drives are used.
In addition, with MAN HydroDrive®, only the rear wheels are powered in road traffic, and no friction is produced by the hydropumps or wheel drives. In contrast, with the all-wheel drive, the transmission elements of the front-axle drive continue to turn, even when they are switched off.
