SELF-PROPELLING WORK MACHINE AND METHOD FOR BRAKING SUCH A WORK MACHINE

摘要

The invention relates to a self-propelling work machine in the form of a tracked vehicle having an electric drive, with a generator drivable by an internal combustion engine, an auxiliary unit connected to the engine, and a braking apparatus for braking the work machine. The braking apparatus provides regenerative braking by the electric drive and comprises a feedback apparatus for feeding back electrical motor braking power of the electric motor to the generator to apply the motor braking power on the engine and on the auxiliary unit. The invention further relates to a method for braking the work machine. In accordance with the invention, a control apparatus is provided for the automatic increase and/or decrease of the power pick-up of the auxiliary unit in dependence on the electrical motor braking power fed back to the engine and/or on the operating state of the engine acted on by motor braking power.
