The present disclosure relates to a nozzle (23, 24) for a rear suction assembly (20) for a road cleaning vehicle (10). The nozzle (23, 24) comprises a nozzle housing (40) forming a nozzle chamber (41) extending and converging between a nozzle inlet (42) and a nozzle outlet (43). At least one guide wall (65, 66, 67, 68, 69) mounted in the nozzle chamber (41) forming a plurality of passageways (70, 71, 72, 73, 74, 75) for dividing air flowing through the nozzle chamber (41) between the nozzle inlet and outlet (42, 43).
Disclosed is a road cleaning machine including a centrifugal fan assembly that includes a fan casing including a casing inlet and a casing outlet and an impeller mounted in the fan casing and rotatable about an axis of rotation for drawing fluid from the casing inlet and directing the fluid to the casing outlet, the impeller includes a splitter wall extending outwardly from the axis of rotation to define first and second blade chambers extending from first and second faces of the splitter wall respectively, the splitter wall including a splitter wall aperture, a plurality of blades being mounted in the first and second blade chambers the impeller being configured to, during rotation about the axis of rotation, direct fluid from the casing inlet through the first and second blade chambers to the fan casing outlet, the fluid being directed into the second blade chamber via the splitter wall aperture.
A driving system (16) is for driving the road cleaning vehicle (10) in a forward direction along a road (18) having debris (9) thereon. Road cleaning equipment (25) is for cleaning the debris on the road and comprising a debris collection system (26). A control system (40) comprises a controller (41) and at least one debris accumulation sensor (70, 71, 73) configured to generate debris accumulation sensor data for identifying blockages of the debris collection system. It does so by locating debris captured by the debris collection system in front of and adjacent to the debris collection system when the road cleaning vehicle is moving in the forward direction and the debris collection system is adjacent the road. The controller receives the debris accumulation sensor data from the debris accumulation sensor and processes it in a debris accumulation model to identify the debris. The road cleaning equipment is operated to release the debris from in front of and adjacent to the debris collection system.
A driving system (16) is for driving the road cleaning vehicle (10) along a road (18) having debris (9) thereon. Road cleaning equipment (25) is for cleaning the debris on the road. A control system (40) comprises a controller (41) and at least one debris sensor (60, 65) comprising at least one image camera for generating first and second debris sensor image data for identifying the type and location of debris in front of and behind the vehicle. The driving system and/or road cleaning equipment is operated by the controller based upon the location and type of debris identified in front of and behind the road cleaning vehicle to control the cleaning of debris on the road by the road cleaning vehicle.
A road cleaning machine (10) comprising a centrifugal fan assembly (20) is provided. The centrifugal fan assembly (20) comprises a fan casing (24) comprising a casing inlet (41) and a casing outlet (43) and an impeller (26) mounted in the fan casing (24) and rotatable about an axis of rotation (28) for drawing fluid from the casing inlet (41) and directing the fluid to the casing outlet (43). The impeller (26) comprises a splitter wall (61) extending outwardly from the axis of rotation (28) to define first and second blade chambers (65, 67) extending from first and second faces (75, 77) of the splitter wall (61) respectively. The splitter wall (61) comprises a splitter wall aperture (69). A plurality of blades (63) are mounted in the first and second blade chambers (65, 67). The impeller (26) is configured to, during rotation (28) about the axis of rotation (28), direct fluid from the casing inlet (41) through the first and second blade chambers (65, 67) to the fan casing (24) outlet, the fluid being directed into the second blade chamber (67) via the splitter wall aperture (69).

This invention is directed toward a powertrain for a road cleaning vehicle. In particular, the powertrain includes a hydrostatic gearbox (34) having a casing (50) for directing power from a primary gearbox to a drivetrain and/or one or more road cleaning tools. The casing (50) comprises first and second sections (51, 52) and a plurality of passageways (107, 107) defined by the edges of both the first and second sections (51, 52). An input shaft is provided having an integral gear extending orthogonally therefrom and having an outer portion extending outside of the internal volume of the casing.
The present invention is directed to a centrifugal fan assembly (19) for the debris collection arrangement (100) of a road cleaning machine (10). The assembly (19) comprises a casing (101), a rotatable impeller (103) and a wall (107). The casing (101) comprises a volute portion (30) connected to an outlet passageway (31), a corner (106) being formed therebetween. The impeller (103) comprises a plurality of blades (25) and is located in the volute portion (30) proximate the corner (106). The wall (107) separates the outlet passageway (31) into a first and second passageway (36, 37) and extends to an inner end (102) proximate the impeller (103). The inner end (102) is positioned, and the impeller (103) is arranged, such that when a blade (25) passes the inner end (102) a second pressure wave is formed that destructively interferes with a first pressure wave formed by a blade (25) passing the corner (106). The distance W between the inner end (102) and impeller (103) is greater than the distance Z between the corner (106) and impeller (103).
