Abstract
A floor care machine realized in the form of a floor polishing machine contains a driven pad, the height of which pad can be adjusted automatically to adjust the application pressure to take the characteristics of the floor into consideration. For this purpose, between the driving element and the driven element, there is a transmission element which forms a torque regulator. For this purpose, the driven element can be rotated with respect to the driving element opposite to the working direction of rotation and can also be displaced axially, whereby the transmission element with a clamping element automatically regulates the displacement and rotation, thereby acting as a torque regulator to regulate the height of the pad with respect to the floor as a function of the torque.
