Document Type and Number:
WIPO Patent Application WO/2023/028922
Kind Code:
A1
Abstract:
A hybrid power system, comprising a first electric motor (EM1) and a second electric motor (EM2), wherein the first electric motor (EM1) is configured to be coaxial with and always coupled, in a transmission manner, to an engine (ICE); the second electric motor (EM2) is configured to be parallel to and staggered with the first electric motor (EM1); and a first input shaft (S1) of a gearbox is coupled to the first electric motor (EM1) in a controlled transmission manner via a first clutch unit (C1), a second input shaft (S2) thereof is coupled to the first electric motor (EM1) in a controlled transmission manner via a second clutch unit (C2), and a third input shaft (S3) thereof is always coupled to the second electric motor (EM2) in a transmission manner. The first input shaft (S1), the second input shaft (S2) and the third input shaft (S3) are respectively always coupled to an intermediate shaft (S4) in a transmission manner by means of different gear pairs. The axial dimension of the whole the hybrid power system is reduced, thereby improving the packaging space of the whole system, simplifying the structure and reducing the costs. Further provided is a vehicle comprising the hybrid power system.
