The invention discloses a cooling and lubricating system of a power assembly, the power assembly and a vehicle, and the cooling and lubricating system of the power assembly comprises a generator oil way used for cooling and lubricating a generator; the pump body is used for providing power for oil flowing of an oil way of the generator; and the transmission oil way is connected with the generator oil way, so that part of oil in the generator oil way flows to the transmission oil way, and the transmission oil way is used for cooling and lubricating a gear and/or a bearing of the transmission. Therefore, direct and accurate lubrication can be realized, a gear and a bearing can be lubricated by oil splashed and can also be lubricated by oil supplied by an oil way of the transmission, so that the gear and the bearing in the transmission can be fully lubricated, and the lubricating device has the advantages of being simple in structure, small in occupied space and low in cost.
本发明公开了一种动力总成的冷却润滑系统、动力总成和车辆,该动力总成的冷却润滑系统包括:发电机油路,发电机油路用于冷却润滑发电机;泵体,泵体用于为发电机油路的油液流动提供动力;变速器油路,变速器油路与发电机油路连接,以使发电机油路内的部分油液流动至变速器油路,变速器油路用于冷却润滑变速器的齿轮和/或轴承。由此,可以实现直接对位准确地进行润滑,可以使得齿轮和轴承不仅受到溅射来的油液润滑,还可以受到变速器油路供应的油液润滑,从而可以使变速器中的齿轮和轴承得到充分的润滑,也具有结构简单、占用空间较小和成本较低的优点。
