Self-propelled construction vehicle and control method for such a vehicle

The machine has landing gears (1) that comprise wheels or chain drive assemblies (1A,1B). A primary power transmission strand transmits driving power of a drive unit (5) on wheels or chain drive assemblies to control the transferred power. A secondary power transmission strand transmits the driving power of the drive unit on a working unit (4). A regulating device controls transferred power over the primary power transmission strand such that the rotation speed difference between the drive shaft and driven shaft of a hydrodynamic gear box corresponds to a given value. An independent claim is included for method for controlling self-propelled construction machine.
