摘要

Mechanical coupling unit, in particular for shafts for the transmission of a rotational movement in the budget - or professional cleaning machines. The unit has a first drive disc (12) and a second pressure plate (13), which coaxially in a transmission shaft (11) are inserted. The first drive disc (12) is connected to the shaft (11) is fastened, and the second pressure plate (13) is in relation to the shaft (11) free and is a transfer clutch (14) associated with it, so that it is clear, a translational motion along the axis of the shaft (11), which transmission clutch (14) with a corresponding cleaning tool (10a) is connected. The first and second disc (12, 13) have mutually opposite surfaces first, radially projecting teeth (15), which are adapted to engage into one another, in order to the transfer of movement up to a predetermined value of the torque to ensure. In the clutch (14), which in relation to the shaft (11) is free, are thrust elements (19, 20) for the second disk, which are designed for this purpose, the second disk (13) to keep pressed, so that they and the first disk (12) of up to predetermined limit values of the transmitted torque engage into each other.
