Motor Cooling Device and Cooling and Lubricating System of Power Coupling Mechanism

Abstract

The invention relates to the field of automobiles and discloses a motor cooling device and a cooling lubricating system of a power coupling system. The motor cooling device comprises at least one liquid injection pipe assembly which is used for injecting cooling liquid to cool a motor. Each liquid injection pipe assembly comprises at least two annular liquid injection pipes which are arranged around the outer contour of the motor and communicate with each another. The annular liquid injection pipes of each liquid injection pipe assembly do not communicate with the annular liquid injection pipes of the other liquid injection pipe assemblies. Multiple first liquid injection nozzles are arranged on the side, close to the motor, of each annular liquid injection pipe around the annular wall. Each liquid injection pipe assembly is provided with a liquid conveying end, wherein the cooling liquid flows into each annular liquid injection pipe in the corresponding liquid injection pipe assembly through the liquid conveying end. According to the motor cooling device and the cooling lubricating system of the power coupling mechanism, the annular liquid injection pipes of the liquid injection pipe assemblies are arranged around a shell of the motor, the multiple first liquid injection nozzles are arranged on the inner side walls, close to the shell of the motor, of the annular liquid injection pipes, and due to the fact that the annular liquid injection pipes are arranged around the shell of the motor, the cooling liquid can be evenly scattered to the whole shell of the motor after being injected out through the first liquid injection nozzles, and the output utilization rate of the cooling liquid is increased.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a motor cooling device and a cooling lubricating system of a power coupling mechanism. Background technique [0002] In the existing transmission or coupling device motor cooling system, the cooling water circuit is directly processed on the motor casing, and the cooling of the motor is realized through the circulation of cooling water in the cooling water circuit. However, the structure of the motor casing in this scheme is relatively complex, the processing of the shell is difficult, and the motor occupies a large space; therefore, it is more feasible to cool the motor by installing a cooling oil pipe outside the motor; however, due to the relatively small space of the transmission or power coupling mechanism, As a result, it is difficult to arrange the oil circuit of the cooling oil pipe.

[0002] In the existing transmission or coupling device motor cooling system, the cooling water circuit is directly processed on the motor casing, and the cooling of the motor is realized through the circulation of cooling water in the cooling water circuit. However, the structure of the motor casing in this scheme is relatively complex, the processing of the shell is difficult, and the motor occupies a large space; therefore, it is more feasible to cool the motor by installing a cooling oil pipe outside the motor; however, due to the relatively small space of the transmission or power coupling mechanism, As a result, it is difficult to arrange the oil circuit of the cooling oil pipe. Generally, the cooling oil pipes are arranged in parallel above or on the side of the motor, resulting in poor cooling effect of the motor. The utilization rate of the cooling oil output in the cooling oil pipe is low, resulting in cooling oil The output is wasted; in addition, this arrangement of cooling oil pipes is not suitable for cooling multiple motors separately, and there are disadvantages in the application
