Abstract:
A cooling unit for a power tool comprises a fan wheel (10) to be supported on an armature shaft (3) of a motor (1) of the power tool. The cooling unit comprises a torque transfer means as well as an actuating means (20, 22) for actuating this torque transfer means so as to selectively transfer the rotation of the armature shaft (3) to the fan wheel (10) during operation of the power tool.
