Description

Technical Field

[0001] The utility model relates to the technical field of engine output, in particular to a hybrid power diesel engine power output structure. Background Art

[0002] The function of the diesel engine power output structure is to output the power of the diesel engine to special equipment such as ships, generators or gearboxes. The traditional power output structure is generally composed of crankshafts, flywheels, clutches and other components. The rear end of the crankshaft is designed as a flange structure, and the outer circumferential surface of the flange is used as the sealing surface of the oil seal. In order to ensure the reliability of power output, the flywheel end of the diesel engine is required to reserve sufficient safety factors.

[0003] At the same time, traditional diesel engines generally transmit engine power to manual transmissions through clutches, and can also interrupt power transmission through clutches. The input power split hybrid special transmission adjusts the engine speed through a planetary gear system and control strategy, and does not need to separate the engine and transmission in terms of mechanical structure. If the clutch assembly is still used to transmit power, the cost is high, the assembly is complicated, and the weight is also large. Utility Model Content
