The invention relates to a sweeper driving system and a road cleaning vehicle comprising the sweeper driving system. The sweeper driving system comprises an oil tank, a hydraulic motor, a hydraulic pump, an electric control flow rate control valve and a controller, wherein the oil tank is used for storing hydraulic oil, the hydraulic motor is used for driving a sweeper of the road cleaning vehicle to rotate for carrying out sweeping operation, the hydraulic pump is communicated with the oil tank and is connected with an oil inlet of the hydraulic motor, an oil outlet of the hydraulic motor iscommunicated with the oil tank through an oil return path, an oil inlet of the electric control flow rate control valve is communicated with an oil inlet path, an oil outlet of the electric control flow rate control valve is communicated with the oil return path, and the controller is electrically connected with the electric control flow rate control valve and is used for regulating the flow rateQ2 of hydraulic oil flowing through the electric control flow rate control valve according to the running speed V of the road cleaning vehicle during the sweeping operation. Through the technical scheme, the relevance can be built between the running speed of the road cleaning vehicle and the rotation speed of the sweeper of the road cleaning vehicle, and the sweeping operation can be efficientlycarried out according to the running state of the road cleaning vehicle.
Description
technical field [0001] The invention relates to the field of road cleaning vehicles, more specifically, to a brush driving device of the road cleaning vehicle and the road cleaning vehicle. Background technique [0002] At present, in vast urban and rural areas, road cleaning vehicles are widely used in road cleaning operations. Existing road cleaning vehicles generally include a vehicle body and a cleaning device carried by the vehicle body. The cleaning device may include brushes driven by a brush driving system, and may also include sprinklers and the like. When the road cleaning vehicle is cleaning the road, the road cleaning vehicle drives on the road to be cleaned, and at the same time, the sweeping brush of the cleaning device rotates under the drive of the hydraulic drive system to clean the road. [0003] Figure 1 to Figure 3 The three traditional hydraulic brush drive systems of the road cleaning vehicle are represented respectively, and the three traditional hyd...
