Single-motor and double-motor type hybrid power sanitation vehicle power system

Abstract

The invention discloses a single-motor and double-motor type hybrid power sanitation vehicle power system. The single-motor and double-motor type hybrid power sanitation vehicle power system comprisesan engine, a loading load and a travelling load; the loading load and the travelling load are driven by a flywheel integrated type motor and a chassis drive motor correspondingly, and the flywheel integrated type motor and the chassis drive motor are connected in series through an energy storage device; the engine and the flywheel integrated type motor are directly connected and integrated into awhole; and a clutch and a transmission device are further arranged between the flywheel integrated type motor and the loading load. The single-motor and double-motor type hybrid power sanitation vehicle power system has the advantages that work noise is small, oil consumption and pollution are low, the work time and space are unlimited, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of automobile hybrid power transmission, more specifically, it relates to a power system of a single-engine double-motor hybrid sanitation vehicle. Background technique [0002] Due to the increasing global energy shortage and environmental pollution, more and more attention has been paid to vehicle exhaust emissions and energy consumption, and the pressure on energy saving and emission reduction of vehicles is increasing. As an important part of urban vehicles, sanitation vehicles are responsible for urban cleaning. Traditional sanitation vehicles generally use diesel engines, which cause secondary pollution to the city's air during urban cleaning. Therefore, more environmentally friendly electric sanitation vehicles should be used. However, due to the constraints of some key technologies, electric sanitation vehicles have disadvantages such as short cruising range and imperfect charging facilities, and san...

Problems solved by technology

As an important part of urban vehicles, sanitation vehicles are responsible for urban cleaning. Traditional sanitation vehicles generally use diesel engines, which cause secondary pollution to the city's air during urban cleaning. Therefore, more environmentally friendly electric sanitation vehicles should be used. However, due to the constraints of some key technologies, electric sanitation vehicles have disadvantages such as short cruising range and imperfect charging facilities, and sanitation vehicles need to work continuously for a long time to meet various cleaning tasks, so electric sanitation vehicles are still available in a short period of time. It is difficult to fully promote the application

At the same time, the traditional fuel sanitation vehicle has one or two fuel engines. When there is only one fuel engine, the engine must not only provide power for the vehicle to walk, but also provide power for the upper load through the PTO; when there are two fuel engines, one The engine provides power for the vehicle to walk, and the other engine provides power for the upper load. The sanitation vehicle powered by the pure engine is noisy when it is working, and the exhaust pollution is serious. fuel consumption area

Electric sanitation trucks work with low noise, but the battery capacity of the vehicle is limited, which makes its working range and working time limited. If the battery capacity of the vehicle is to be increased, it will take up a lot of space on the one hand, and it will also make the entire vehicle Car costs rise sharply
