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 channel and an oil return channel. The oil pumping channel comprises a plurality of oil distributing channels, and the oil outlet positions of the oil distributing channels correspond to a to-be-cooled part and a to-be-lubricated part in the motor shell and a to-be-cooled part and a to-be-lubricated part in the speed reducer shell respectively. The oil pumping assembly is used for pumping lubricating oil in the first shell into the oil pumping channel and conveying the lubricating oil to a to-be-cooled part and a to-be-lubricated part through the oil distributing channels. The oil return channel is arranged at the bottom of the second shell and used for enabling lubricating oil in the second shell to flow back into the first shell; wherein the first shell is a motor shell, and the second shell is a speed reducer shell; or, the first shell is a speed reducer shell, and the second shell is a motor shell. According to the cooling and lubricating device, active and directional cooling and lubricating of the to-be-cooled part and the to-be-lubricated part can be achieved, and the cooling and lubricating efficiency is higher.

    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、泵油通道和回油通道;泵油通道包括若干分油通道,各分油通道的出油位置分别对应电机壳体内的待冷却零件和待润滑零件,以及减速器壳体内的待冷却零件和待润滑零件;泵油组件用于把第一壳体内的润滑油泵入泵油通道,通过各分油通道输送到待冷却零件和待润滑零件处;回油通道设置在第二壳体底部,用于使第二壳体内的润滑油回流到第一壳体内;其中,第一壳体为电机壳体,第二壳体为减速器壳体;或者,第一壳体为减速器壳体,第二壳体为电机壳体。该冷却润滑装置可实现对待冷却零件和待润滑零件的主动且定向冷却和润滑,冷却和润滑效率更高。
