The invention discloses a cooling and lubricating system adopting a motor and gearbox coupling design and a hybrid electric vehicle. The system comprises a motor system and a gearbox system, the motor system comprises a low-temperature area unit, a medium-low-temperature area unit and a medium-temperature area unit, and the low-temperature area unit and the medium-low-temperature area unit exchange heat with a first cooling system and a second cooling system respectively; the system further comprises a third cooling system, the gearbox system and the medium temperature zone unit exchange heat with the third cooling system, and the output end of the second cooling system is connected with the input end of the third cooling system. The gearbox and the motor medium-temperature zone cooling system are connected behind the motor low-temperature zone cooling system and the medium-low-temperature zone cooling system in series, motor cooling liquid is reutilized, the efficiency of the hybrid power automobile cooling system is improved, and the requirement for the total flow of the cooling liquid is reduced.

    本发明公开了一种电机与变速箱耦合设计的冷却润滑系统及混动汽车。它包括电机系统和变速箱系统,所述电机系统包括低温区单元、中低温区单元和中温区单元,所述低温区单元和中低温区单元分别与第一冷却系统和第二冷却系统进行热交换;还包括第三冷却系统,所述变速箱系统和中温区单元与第三冷却系统进行热交换,所述第二冷却系统的输出端连接第三冷却系统的输入端。本发明将变速箱及电机中温区冷却系统串联在电机低温区、中低温区冷却系统的后面,对电机冷却液进行二次利用,提升了混动汽车冷却系统效率,降低冷却液总流量需求。
