Abstract
The invention discloses a hybrid power driving system and a vehicle. The hybrid power drive system includes an engine, a first clutch, a second clutch, an integrated starter and generator, a battery, a drive axle and a first operating system, wherein the integrated starter and generator is connected with the engine through the first clutch; the battery is connected with the integrated starter and generator; the drive axle is connected with the integrated starter and generator; the first operating system is connected with the engine through the second clutch. By the technical scheme of the invention, decoupling of the power of the first operating system and the power of the drive axle can be realized, and the engine and the integrated starter and generator can jointly provide power for the drive axle, so the hybrid power drive system has low power requirements on the engine and the integrated starter and generator, and can be configured with a small-power engine and a small-power integrated starter and generator, so that the power and the size of the integrated starter and generator can be effectively reduced.
Description
technical field [0001] The invention relates to the field of vehicles, in particular to a hybrid drive system and a vehicle. Background technique [0002] The sweeper has both the functions of sweeping the road and washing with high and low pressure water. It has the advantages of high-quality road surface cleaning and no dust generation. It can effectively reduce the labor intensity of sanitation workers and is widely used in the field of road cleaning in cities and expressways. . [0003] Under normal circumstances, the washing and sweeping car products are driven by dual engines. The main engine of the chassis only provides power for the driving system to drive the vehicle, while the auxiliary engine is only responsible for providing power for the upper-mounted operating system. When the road sweeper is working normally, since the walking power provided by the main engine of the chassis only accounts for 15% to 30% of the total engine power, the engine does not work in t...
