Title:
ELECTRIC OIL PUMP ASSEMBLY, STEERING SYSTEM AND LUBRICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/001199
Kind Code:
A1
Abstract:
An electric oil pump assembly, a steering system and a lubrication system; the electric oil pump assembly (1000) comprises: a motor assembly (200), an oil pump assembly (100) and an elastic member (311); the oil pump assembly (100) is floatingly mounted at an end portion of the motor assembly (200), and is connected to a motor shaft (250) of the motor assembly (200) by means of power coupling; the elastic member (311) is elastically connected between the motor assembly (200) and the oil pump assembly (100) so as to apply an axial preload force facing the motor assembly (200) to the oil pump assembly (100). The electric oil pump assembly (1000) has high working energy efficiency, and low requirements in processing precision and assembly precision.
