Abstract (en)
[origin: US4760657A] 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.
