Summary:The invention relates to a driving device for a wheel of a work machine, comprising an electric motor, which has a rotor rotatably accommodated in a stator, which rotor is supported on end shields arranged at end faces, between which end shields winding-head spaces for accommodating winding heads are provided, wherein a cooling device for cooling the stator and the rotor has at least one coolant path through the winding-head spaces, which at least one coolant path can be supplied with coolant by means of a preferably circumference-side coolant inlet from a circumference side. According to an advantageous design of the invention, the stator and a stator winding of the stator are cooled from an outer circumference side of the stator and for this purpose a space around the electric motor or the stator of the electric motor present as the installation environment of the electric motor is used, such that the cooling air flow can flow from the outer circumference side of the stator. The coolant introduced into the motor interior can flow away again via only one end shield at an end face of the electric motor, while the other end shield preferably facing a gearing can be designed closed.
