Embodiment Construction

[0008] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0009] exist figure 1 Among them, during the cleaning operation, the engine 2 drives the vehicle running at a low speed, and at the same time drives the generator 6 to generate electricity to drive various motors to complete the cleaning operation, and can also charge the power battery pack 8 as required. When the vehicle is running on the road, according to the state of charge of the power battery pack 8 , the power battery pack 8 can be started to be charged, which also increases the load rate of the engine 2 . When the vehicle is not working, the power battery pack 8 can also be charged with an external power supply. The engine 2 drives the automobile in a traditional connection mode, and a power take-off 4 is installed on the engine 2 transmission to drive the generator 6 to provide power for the cleaning system and the power battery pack 8 . The ...

Abstract

The invention relates to the field of a road sweeping vehicle and provides a hybrid power driving system for a large-size road sweeping vehicle. An engine is connected to a driving wheel, a fuel tank and a power takeoff, wherein the other end of the power takeoff is connected to a generator; the generator is controlled by a motor controller; the generator is connected to a power battery pack and a sweeping controller through an AC/DC (Alternating Current/Direct Current) controller; the other end of the power battery pack is connected to a 220V charger; and the other end of the sweeping controller is connected to an oil pump motor, a water pump motor, a sweeping motor and a dust-absorbing motor. By adopting the technical scheme, only an internal combustion engine is required by the system. When the vehicle is driven by the engine, the vehicle or a working device can be separately or simultaneously driven by the hybrid power driving system, and the engine can run in a high-efficiency area, thereby promoting the load rate of the engine and reducing the oil consumption.

Description

technical field [0001] The invention relates to the field of road sweeping vehicles, and relates to a hybrid driving system of a large road sweeping vehicle. Background technique [0002] In recent years, under the background of the rapid development of expressways and urban roads in our country and the vigorous promotion of the activities of striving for a civilized and hygienic city, road sweepers have been widely used in our country due to their high efficiency, fastness and safety. Sweepers are widely used in urban roads, squares, airports, stadiums, docks, schools and other places to undertake cleaning and cleaning tasks. Road sweeping vehicles have maintained a momentum of rapid development, but problems such as low vehicle dynamic workload, high fuel consumption, and high working noise have also emerged. Traditional sweeping vehicles mostly use a dual-engine solution, that is: one main engine drives the car, and the other auxiliary engine drives the hydraulic system,...
