Abstract (en)
An oscillating suspension means for a brush of a sweeping machine, comprising a support frame for the rotating brush (2), which is suspended from a frame of the machine by means of a double-acting first piston-cylinder group (53) supplied by a pump via a four-way distributor (10), activated either automatically or manually by an operator, the cylinder (5) of the first piston-cylinder group (53) being placed in series with a single-acting second piston-cylinder group (51) made sensitive to means for detecting a sharp rising of the brush.
