Title:
HYBRID POWER SYSTEM FOR CRANE, CONTROL METHOD, VIRTUAL DEVICE AND CRANE
Document Type and Number:
WIPO Patent Application WO/2022/237478
Kind Code:
A1
Abstract:
A hybrid power system for a crane, a control method, a virtual device and the crane. In the hybrid power system, an output end of an engine (10) is connected to an input end of a gearbox (20); one end of a power takeoff (30) is connected to one output end of the gearbox (20), and the other end of the power takeoff (30) is connected to an input end of a driving electric motor (40); an output end of the driving electric motor (40) is connected to a multi-connected oil pump (50); a central controller (90) is connected to the engine (10) and a hybrid controller (100) separately; the hybrid controller (100) is connected to the driving electric motor (40) and a power source (60) separately; the engine (10), the gearbox (20), the power takeoff (30), the driving electric motor (40) and the multi-connected oil pump (50) are connected to form a first hydraulic passage used for providing power for a loading operation of the crane; and the power source (60), the driving electric motor (40) and the multi-connected oil pump (50) are connected to form a second hydraulic passage used for providing power for the loading operation of the crane. According to the hybrid power system, an output shaft of the driving electric motor (40) and an output shaft of the power takeoff (30) are integrally designed such that the output shaft can be driven by an electric motor stator or be driven by the engine (10), thereby optimizing power distribution of the hybrid power system.
