Abstract

The invention discloses an integrated oil pump which comprises a motor assembly. One end of the motor assembly is connected with an oil pump assembly, one end of the oil pump assembly is connected with a controller assembly, and the oil pump assembly is arranged between the controller assembly and the motor assembly. A plurality of through holes for connecting the interior of the motor assembly and the interior of the oil pump assembly are formed in the connecting surface of the oil pump assembly and the motor assembly. The interior of the motor assembly and the interior of the oil pump assembly are communicated through the through holes, oil in the oil pump assembly can flow into the motor assembly, so that the motor is cooled, and the stable and safe operation of the oil pump is achieved. And meanwhile, the controller assembly, the oil pump assembly and the motor assembly are integrated together, so that the size of the device can be greatly reduced, and the convenience of the deviceis improved. By adopting an integrated injection molding controller shell with a connector, the structure is simplified, the integration is improved, and the cost is reduced.

Description

technical field [0001] The invention relates to the field of pump bodies, in particular to an integrated oil pump. Background technique [0002] Oil pumps are more and more frequently used in gearboxes and transmission systems. Using this technology can improve transmission efficiency and reduce energy consumption, thereby reducing fuel consumption and carbon dioxide emissions. In particular, the use of electronic oil pumps can improve the performance of oil pumps in different applications. Flexibility and availability. In automatic transmissions, continuously variable transmissions and dual-clutch transmissions, the electronic pump drives the actuator hydraulically or loads an accumulator, which can be used to lubricate and cool the transmission system when the engine is stationary or without engine intervention. Contents of the invention [0003] The purpose of the present invention is to provide an integrated oil pump in view of the above-mentioned problems, which inte...
