Abstract
Improvements in self-sweeping vehicles, essentially characterized by the fact that the brush-roller is directly driven by means of a motor unit independent of the vehicle's own engine, the operation of this roller-broom being absolutely autonomous and free with respect to the rotation of the wheels of the vehicle, and said roller-broom being mounted on a movable frame in combination with means to move it up and down making the transmission of the rotary movement to the roller-broom, by means of suitable transmission devices preferably by trapezoidal pulleys, with the aid of a tensioning device governed by the displacement of the mobile frame or by other suitable transmission means.
