The invention discloses an oil circulation device, a double-motor electric drive system and a vehicle, the oil circulation device comprises a shell, a first gear cavity, a motor cavity and a second gear cavity are formed in the shell, and at least one first oil return hole is formed between the first gear cavity and the motor cavity; at least one second oil return hole is formed between the second gear cavity and the motor cavity; the spraying system is provided with an oil inlet and a plurality of oil spraying ports, the spraying system is configured to suck oil from the oil inlet and spray the oil from the oil spraying ports, the oil inlet is communicated with the motor cavity, the oil spraying ports are communicated with the first gear cavity, the motor cavity and the second gear cavity, and the first gear cavity, the motor cavity and the second gear cavity are relatively independent, so that mutual influence is reduced; the motor and the gear are subjected to flow distribution and forced lubrication through the spraying system, the first oil return hole and the second oil return hole ensure that oil can smoothly flow back to the motor cavity when the whole vehicle inclines, the spraying system is prevented from sucking air, and oil circulation in the three cavities can be achieved.
本发明公开了一种油液循环装置、双电机电驱系统和车辆,油液循环装置包括壳体,壳体的内部形成有第一齿轮腔、电机腔和第二齿轮腔,第一齿轮腔与电机腔之间设置有至少一个第一回油孔,第二齿轮腔与电机腔之间设置有至少一个第二回油孔;喷淋系统,具有入油口和多个喷油口,喷淋系统配置为能从入油口吸入油液,并将油液从喷油口喷出,入油口连通于电机腔,喷油口连通于第一齿轮腔、电机腔以及第二齿轮腔,第一齿轮腔、电机腔和第二齿轮腔相对独立,减少彼此影响,电机与齿轮通过喷淋系统进行流量分配和强制润滑,第一回油孔和第二回油孔保证整车倾斜坡度时油液能顺利回流至电机腔,防止喷淋系统吸空,均能实现三个腔体内的油液循环。
