Abstract: The sweeping brush of the machine is composed of two or more parts in order to maintain a constant pressure of the sweeping brush against the ground, to achieve faster clearance of the snow, and to avoid downtime for adjustments. These brush parts are swivellable relative to one another in a vertical plane. The common raising and lowering movement of the individual parts is controlled by a cylinder-piston unit, and the piston acting upon the brush parts is always impinged upon by a pressure opposite to the direction of movement. The individual brush parts may be connected to one another by torsion bars.
