The invention discloses an oil cooling device, a power assembly and a vehicle, the oil cooling device comprises a box body and an oil pumping assembly, the box body is provided with an oil inlet hole and an oil outlet hole, the oil inlet hole is communicated with a first oil storage space and a mounting groove, and the oil outlet hole is communicated with the mounting groove; the oil pumping assembly comprises a driving part and a piston, the piston is arranged in the mounting groove, a second oil storage space is defined by the piston and the groove wall of the mounting groove, and the driving part is used for driving the piston to reciprocate in the mounting groove; when the piston moves in the first direction, the second oil storage space is enlarged so that oil in the first oil storage space can be sucked into the second oil storage space through the oil inlet hole. And when the piston moves in the second direction, the second oil storage space is reduced, so that oil in the second oil storage space is discharged through the oil outlet hole. According to the oil cooling device, the pressure difference exists between the second oil storage space and the first oil storage space, oil can enter the second oil storage space easily, the oil can be pumped to the position to be cooled and lubricated, and the cooling and lubricating effect of the motor is improved.

    一种油冷装置、动力总成及车辆,油冷装置包括箱体和泵油组件,箱体上设有进油孔和出油孔,进油孔连通第一储油空间和安装槽,出油孔与安装槽连通;泵油组件包括驱动件和活塞,活塞设于安装槽中,活塞与安装槽的槽壁围成第二储油空间,驱动件用于驱动活塞在安装槽内做往复运动;当活塞沿第一方向移动时,第二储油空间增大,以将第一储油空间中的油液经进油孔吸入第二储油空间中;当活塞沿第二方向移动时,第二储油空间减小,以将第二储油空间中的油液经出油孔排出。本申请提供的油冷装置,通过使第二储油空间与第一储油空间具有压力差,有利于油液进入第二储油空间中,并能够将油液泵送至待冷却润滑位置处,提升电机的冷却润滑效果。
