Working Machine and a Method for Operating a Working Machine
First Claim
1. A working machine comprisingan internal combustion engine for supplying torque to driving wheels of the working machine,a transmission line arranged between the internal combustion engine and the driving wheels for transmitting torque from the internal combustion engine to the driving wheels,at least one hydraulic pump in a hydraulic system for at least one of moving an implement arranged on the working machine and steering the working machine,wherein the transmission line comprises at least one electric machine for at least one of driving the driving wheels braking the driving wheels and generating electric power for the at least one hydraulic pump, wherein the transmission line comprises a transmission unit for engagement and disengagement of the internal combustion engine relative to the driving wheels, wherein the transmission line comprises at least one electric machine arranged between the transmission unit and the driving wheels and the at least one electric machine arranged between the transmission unit and the driving wheels is arranged between the transmission unit and a gearbox.
