The present invention relates to a sweeper (100) comprising two main wheels (210a, 210b), at least one accessory (410, 420, 440) especially intended for sweeping or suction, a means of driving said accessory via the main wheels, a dust collection bin (430), said accessory being composed of a brush (420) having a horizontal axle intended for sending the dust into the collection bin (430), the brush (420) having a horizontal axle being rotated by a hydraulic motor (520). The sweeper is noteworthy in that the hydraulic motor (520) is coupled to two hydraulic pumps (560a, 560b), which are connected in parallel and respectively rotated by the two main wheels (210a, 210b) or the hydraulic motor (520) is connected to one hydraulic pump (560c), driven by a differential bridge (240) that is driven by the two main wheels (210a, 210b). By virtue of this hydraulic transmission, the sweeper thus uses its two main wheels, in all circumstances, to drive its accessory or accessories. It operates both when it is moved in a straight line or when it follows a curved trajectory. |
