The invention discloses a cooling and lubricating device of an electric drive assembly and the electric drive assembly. The cooling and lubricating device comprises an oil pumping assembly, an oil pumping path and an oil return path. The oil pumping way comprises an oil inlet pipe, an in-shaft oil way and a first oil outlet hole channel which are sequentially communicated, the in-shaft oil way extends in the motor shaft in the axial direction, the oil pumping assembly pumps lubricating oil in the speed reducer shell into the in-shaft oil way through the oil inlet pipe, and the first oil outlet hole channel is formed in the peripheral wall of the motor shaft. The in-shaft oil duct is used for throwing lubricating oil in the in-shaft oil duct to a part to be cooled and lubricated in the motor shell, an axial flow impeller is arranged in the in-shaft oil duct, and the lubricating oil at the oil inlet end of the in-shaft oil duct can be pumped to the oil outlet end of the in-shaft oil duct; the oil return way is arranged at the bottom of the motor shell and used for enabling lubricating oil in the motor shell to flow back into the speed reducer shell. The cooling and lubricating device can ensure that each part to be cooled and lubricated in the motor shell can obtain sufficient lubricating liquid, and has the advantages of good cooling and lubricating effect, simple structure, low manufacturing cost and the like.
本发明公开了一种电驱动总成的冷却润滑装置和电驱动总成。其中,冷却润滑装置包括泵油组件、泵油路和回油路;泵油路包括依次连通的进油管、轴内油道和第一出油孔道,轴内油道在电机轴内沿轴向延伸,泵油组件通过进油管把减速器壳内的润滑油泵入到轴内油道中,第一出油孔道设置在电机轴的外周壁上,用于将轴内油道中的润滑油甩至电机壳内的待冷却润滑部件处,轴内油道中设有轴流叶轮,可把轴内油道的进油端处的润滑油泵向轴内油道的出油端;回油路设置在电机壳的底部,用于使电机壳内的润滑油回流到减速器壳内。该冷却润滑装置能够保证电机壳内各待冷却润滑部件均能够获得充足的润滑液,具有冷却润滑效果好、结构简单、制造成本低等优点。
