Abstract:
A floor care appliance in the form of a brush vacuum cleaner having a brush set facing the floor for receiving a driven brush roller with an overload protection. A drive disk is mounted rotatably on the shaft and the shaft has a torque-proof output element to the brush roller and the drive disk is coupled via a torsion spring to a coupling disk which is displaceable axially on the shaft and which is coupled in a torque-proof manner via cams to the shaft. Ramps are formed on the drive disk which, above a torque threshold, axially adjust the coupling disk with corresponding ramps by relative twisting. A safety shutdown can be controlled via the adjusting movement via a corresponding switching element of a circuit arrangement.
