COOLING ASSEMBLY OF TORQUE GENERATION ASSEMBLY, HYBRID ELECTRIC AUTOMOBILE EQUIPPED WITH IT, AND METHOD OF COOLING TORQUE GENERATION ASSEMBLY

摘要

PPROBLEM TO BE SOLVED: To eliminate subordination of an operating speed of the cooling assembly relating to a torque generation assembly. PSOLUTION: One or a plurality of the torque generation assemblies like an internal combustion engine 14 and an electric motor 16 are cooled by using a variable speed pump assembly 28 which can be selectively operated without using any of the internal combustion engine 14 and the electric motor 16.
