Abstract: A snow sweeper roller is mountable on a streetcleaning vehicle so that it is suspended and is vertically swingable and rotatable about a horizontal longitudinal shaft capable of being set oblique to the lengthwise direction of the vehicle on its under side. To avoid damage to a curb-end bearing of the sweeper roller, the bearing is provided with a guard on the outside of which has a forward cone converging towards the axis of the bearing shaft. The guard is mounted centrically rotatable on a cover of the bearing of the sweeper roller.

Abstract: A snow-sweeping roller for replaceable attachment to a utility road vehicle (1) having brush-equipped roller (4) rotatably affixed at the underside of the vehicle. To achieve low-wear operation of the sweeper roller (4) and simultaneously low energy consumption, a control device is provided for adjusting and changing roller rpm in accordance with the following factors:(a) The circumferential speed (w) of the roller changes in proportion to vehicle speed (f);(b) The circumferential speed (w) of the roller has a ratio to the vehicle speed (f) that ranges from unity to two; and(c) A minimum value of the circumferential speed (w-min) of the roller is established for when the vehicle is moving slowly or is stationary.
