Further, by filling the cooling lubricating fluid in the transmission accommodating cavity 120 and the cooling lubricating fluid can cool the case assembly 100 , the cooling lubricating fluid can not only be used to cool the transmission 400 , but also facilitate control. The temperature range of the transmission 400 ensures the normal working performance of the transmission 400, and since the cooling lubricant can simultaneously cool the case assembly 100, on the one hand, the temperature range of the case assembly 100 can be controlled, so that the case assembly can be 100 can operate stably within a suitable temperature range, and the motor 200 in the box assembly 100 can be further cooled through the box body assembly 100, thereby facilitating the improvement of the overall heat dissipation performance of the electric assembly 1 and the work of the electric assembly 1. reliability and stability.

Therefore, the electric power assembly 1 according to the embodiment of the present invention has the advantages of compact structure and good cooling effect.

The electric power assembly 1 according to the specific embodiment of the present invention will be described below with reference to the accompanying drawings.

In some specific embodiments of the present invention, as shown in FIGS. 1-22 , the electric power assembly 1 according to the embodiment of the present invention includes a case assembly 100 , a motor 200 , a transmission 400 and a cooling lubricant.

Specifically, the mounting plate 160 is configured as a part of the case assembly 100 , and the cooling lubricating fluid cools the case assembly 100 through the mounting plate 160 . This not only facilitates the setting of the mounting plate 160, but also can transfer heat through the mounting plate 160 to improve the overall cooling effect of the electric assembly 1. For example, the mounting plate 160 can be cooled by the cooling lubricant in the transmission accommodating cavity 120, The box assembly 100 transfers heat through the mounting plate 160 , and further cools the motor housing 140 , thereby cooling the motor 200 in the motor housing 140 .

According to one embodiment of the present invention, the mounting plate 160 is configured as part of the front case 180 because the transmission lubricant cools the front case 180, allowing the mounting plate 160 and the case assembly 100, such as the motor housing 140 and the The transmission case 101 may also be cooled. For example, cavities 162 are formed between the ribs of the mounting plate 160, so the air flowing through the cavities 162 is also cooled accordingly, and the motor 200 can be cooled by using the air flowing through the cavities 162, which is convenient to improve the overall electric motor into 1 heat dissipation performance. In conclusion, the motor housing 140 and the housing of the transmission 400 can be cooled simultaneously by the lubricating fluid in the transmission 400 .

According to another embodiment of the present invention, the mounting plate 160 is configured as part of the motor housing 140 , because the motor lubricant cools the motor housing 140 , which also cools the mounting plate 160 and passes through the mounting plate 160 . The heat is transferred, so that the transmission case 101 can also be cooled, so that the case assembly 100 is cooled, and the overall cooling effect of the electric assembly 1 is improved. In conclusion, the motor housing 140 and the transmission 400 can also be cooled simultaneously by the lubricating fluid in the motor 200 .

Optionally, as shown in FIG. 19 , the electric assembly 1 further includes an oil pump 13 . The oil pump 13 is provided on the case assembly 100 and is used to deliver the cooling lubricant in the transmission accommodating cavity 120 to the transmission 400 and install it. plate 160. In this way, the oil pump 13 can be used to drive the cooling lubricating liquid to flow in the casing assembly 100 , and the cooling lubricating liquid can be delivered to the mounting plate 160 to facilitate cooling of the mounting plate 160 , and further the casing assembly 100 passes through the mounting plate 160 . The heat is transferred to facilitate cooling of the motor housing 140, thereby cooling the motor 200 in the motor housing 140, further improving the cooling effect of the transmission 400 and the mounting plate 160, and cooling the motor 200 through the mounting plate 160, Thereby, the overall cooling effect of the electric assembly 1 is further improved.

Specifically, the motor housing 140 can be provided with a motor cooling liquid channel, which can cool the motor 200. The motor housing 140 is sleeved on the outer periphery of the stator to facilitate cooling and heat dissipation of the stator, and the mounting plate 160 is provided on the motor 200. On the end side, the end of the motor 200 and the coil are mainly cooled and dissipated to achieve the effect of fully cooling the motor 200. The two cooling methods have their own emphasis, and jointly achieve the effect of sufficient cooling. On the other hand, the transmission 400 is cooled by the motor coolant of the motor 200, and the motor 200 is cooled by the lubricating coolant of the transmission 400. The combination of the two enhances the cooling effect on the electric assembly 1, and together achieves sufficient cooling of the electric assembly 1. Effect.

In a specific embodiment of the present invention, as shown in FIG. 20 , the oil pump 13 is installed in the case assembly 100 , and the oil pump 13 is drivingly connected with the transmission 400 to be driven by the transmission 400 . In this way, the oil pump 13 is driven by the transmission 400 to deliver the cooling lubricating liquid to the transmission 400 , which facilitates the setting of the oil circuit of the electric assembly 1 and facilitates the electric assembly 1 to obtain more sufficient lubrication and cooling.

Furthermore, the oil pump 13 is used to lubricate the transmission 400, and the electric assembly 1 does not have high requirements for the space arrangement of the gear shaft. Even if the arrangement of the gear shaft is relatively high relative to the oil level, it can lubricate the key parts in time. The arrangement angle of 1 on the vehicle will be wider, and the suitable powertrain installation angle can be adjusted according to the layout of the vehicle, with high adaptability.

In addition, by driving the oil pump 13 through the transmission 400, there is no need to provide additional power (such as a motor) to drive the oil pump 13, the structure is simple, the adaptability is good, and the amount of cooling lubricant can be adjusted according to the speed of the vehicle, and the lubrication efficiency is high.

Further, as shown in FIG. 19 , the oil pump 13 has a mounting seat 135 , and the oil pump 13 is mounted on the inner wall of the transmission accommodating cavity 120 through the mounting seat 135 . Specifically, the mounting seat 135 is provided at the bottom of the oil pump 13 , the mounting seat 135 is provided with mounting holes, and bolts are inserted into the mounting holes to be threadedly connected to the inner wall of the transmission case 101 . Fixed effect is good. At the same time, the oil pump 13 is arranged inside the transmission 400, and can utilize the internal power of the electric assembly 1 for transmission without occupying an external space.

Specifically, as shown in FIG. 19 , the oil pump 13 includes a rotating shaft 134 connected with a driving gear 131 , the driving gear 131 is drivingly connected with the transmission 400 , and the oil pump 13 is drivingly connected with the driving gear 131 through the rotating shaft 134 to be driven by the driving gear 131 . Thereby, the rotation effect of the drive gear 131 is more stable. In this way, the driving gear 131 on the oil pump 13 can drive the rotating shaft 134 to rotate so that the oil pump 13 pumps oil. Therefore, there is no need to provide an additional motor to drive the oil pump 13, and the displacement of the oil pump 13 is determined by the rotational speed of the driven gear. The lubricating effect will not worsen as the vehicle speed increases; however, when the vehicle speed is low, that is, the rotational speed of the driven gear is slow, the transmission 400 has relatively little demand for the cooling and lubricating fluid volume, and the displacement of the oil pump 13 is also low. , further improving the lubrication efficiency of the transmission 400 .

More specifically, the oil pump 13 is drivingly connected with the driving gear 131 through the rotating shaft 134 . When the driving gear 131 rotates, it drives the rotating shaft 134 to rotate, and the rotating shaft 134 is connected with the gears or vanes inside the oil pump 13 to drive the gears or vanes inside the oil pump 13 to rotate.

The driving gear 131 can be a metal gear or a non-metal gear, and the lightest gear can be selected according to actual needs. Thereby, the rotation effect of the drive gear 131 is more stable. The oil pump 13 can be a gear pump, and the rotating shaft 134 can drive the gears inside the oil pump 13 to rotate, so that the low-pressure cooling lubricating fluid sucked into the oil pump 13 becomes the high-pressure oil discharged from the oil pump 13; the oil pump 13 can also be a vane pump, and the rotating shaft 134 can The impeller inside the oil pump 13 is driven to rotate to increase the pressure of the cooling lubricating fluid. The oil pump 13 of the electric assembly 1 in the embodiment of the present invention refers to a device that can transport the cooling lubricating fluid to each key part of the transmission 400 .

Specifically, the electric assembly 1 further includes an oil delivery pipe, and the oil pump 13 delivers the cooling lubricating liquid in the transmission accommodating cavity 120 to the mounting plate 160 through the oil delivery pipe. In this way, the cooling lubricating liquid can be transported smoothly, the transport capacity and cooling effect of the cooling lubricating liquid can be improved, the cooling lubricating liquid can be transported to the mounting plate 160, and the mounting plate 160 can be cooled. The assembly 100 transfers heat through the mounting plate 160 , which further facilitates cooling of the entire case assembly 100 .

More specifically, the oil pump delivers the cooling lubricating fluid in the transmission accommodating cavity to the mounting plate and at least one gear and/or at least one bearing and/or at least one meshing place through an oil delivery pipe. In other words, the oil pump 13 can deliver the cooling lubricating fluid to at least one of the gears, the bearings and the meshes through the oil delivery pipe. The oil delivery pipe delivers the cooling lubricating fluid in the transmission case 101 to the oil pump 13 , and then the oil pump 13 delivers the cooling lubricating fluid to the driving bearing, the engagement between the driving gear and the first transmission gear, and the transmission bearing. It can be understood that the location where the oil delivery pipe delivers the cooling lubricating fluid to the transmission mechanism 12 is only for better understanding of the present invention, and cannot be understood as a limitation of the present invention.

According to another embodiment of the present invention, as shown in FIGS. 21 and 22 , the oil pump 13 is installed outside the casing assembly 100 . In this way, the arrangement of the oil pump 13 can be avoided to affect the internal structure of the case assembly 100 , and the flexibility of arrangement of the oil pump 13 can be improved. At the same time, it can meet the lubrication requirements of key parts such as bearings and gears, and the lubrication effect is good.

Specifically, the oil pump 13 is driven by an external motor or driven by the transmission mechanism of the transmission 400 . In this way, the oil pump 13 can be powered, the flexibility of the oil pump 13 can be improved, the oil pump 13 can transport the cooling lubricating liquid, and the cooling performance of the electric assembly 1 can be further improved.

Optionally, the wall of the case assembly 100 is provided with an oil guide channel that communicates with the transmission accommodating cavity 120 and the oil pump 13 . Specifically, the oil guide flow channel is formed in the wall of the case assembly 100 by means of perforation. This facilitates smooth transportation of the cooling lubricating liquid, and facilitates the cooling and lubricating liquid to dissipate heat and cool down the electric assembly 1 . In particular, it is convenient to lubricate the bearing and spline lubrication. For example, the oil guide channel can be extended to the bearing or spline, and the cooling lubricant can be directly delivered to the bearing or spline, so as to avoid the oil spray affecting the cooling and lubrication effect. .

Specifically, the oil pump 13 delivers the cooling lubricating fluid in the transmission accommodating cavity 120 to the mounting plate 160 and at least one gear and/or at least one bearing and/or at least one meshing place through the oil guide flow passage. Specifically, the oil pump 13 can deliver the cooling lubricating fluid to at least one of the gears, the bearings and the meshes through the oil guide flow passages. This not only facilitates the delivery of the cooling lubricating fluid to the mounting plate 160, facilitates the cooling lubricating fluid to cool the mounting plate 160, facilitates the transfer of heat through the mounting plate 160, but also facilitates improving the lubrication at the gears, bearings and meshes. The lubrication performance of at least one place is convenient for the electric assembly 1 to work smoothly, and it is convenient to improve the reliability and stability of the electric assembly 1 .

Optionally, the distance between the motor 200 and the mounting plate 160 is smaller than a preset distance. It should be understood here that the preset distance is the maximum distance for the mounting plate 160 to cool the motor 200 , which can be obtained by those skilled in the art from the rated voltage and rated current of the electric motor assembly 1 . For example, the distance between the motor 200 and the mounting plate 160 may be less than 10 mm, preferably 7.5 mm. Since the motor is close to the mounting plate 160, the motor 200 and the mounting plate 160 can be cooled in a short distance from each other. After the mounting plate 160 is cooled, the motor 200 can be rapidly cooled. Optionally, as shown in FIGS. 9 and 10 , the side of the mounting plate 160 facing the motor 200 and/or the transmission 400 is provided with ribs. Because the ribs enhance the rigidity of the box assembly 100 and increase the natural frequency, the resonance of the electric assembly 1 can be avoided, and the noise of the electric assembly 1 can be easily reduced. In this way, the contact area between the cooling lubricating liquid and the mounting plate 160 can be increased, so that the cooling lubricating liquid can cool the mounting plate 160 more sufficiently.

Specifically, during the rotation of the motor 200, the stress is transmitted to the case assembly 100 through the bearing, and adding the ribs on the case assembly 100 is beneficial to increase the rigidity and strength of the case assembly 100, and avoid the overall 100 is in contact with the coil of the motor 200 to prevent damage to the components of the motor 200 and further improve the working reliability and stability of the motor 200 .

Further, the rib divides the space between the mounting plate 160 and the motor 200 into a plurality of cavities 162 . This facilitates the formation of the cavity 162 and facilitates cooling of the motor 200 with the air passing through the cavity 162 .

According to an embodiment of the present invention, as shown in FIG. 12 , the rib includes an annular rib 163 extending along the circumferential direction of the motor 200 . In this way, the rigidity and strength of the case assembly 100 can be improved, the structural stability of the case assembly 100 can be improved, and the heat dissipation capability and cooling effect of the case assembly 100 can be improved.

According to another embodiment of the present invention, as shown in FIG. 10 , the rib includes a rib 161 extending in the radial direction of the motor 200 , and the rib 161 is a plurality of rib 161 . They are spaced apart along the circumference of the mounting plate 160 . In this way, the force of the box assembly 100 can be made more uniform, which further facilitates improving the rigidity and strength of the box assembly 100, further facilitates improving the noise reduction performance and heat dissipation of the electric assembly 1, and improving the cooling effect of the electric assembly 1. .

According to another embodiment of the present invention, the rib includes an annular rib 163 extending in the circumferential direction of the motor 200 and a strip-shaped rib 161 extending in the radial direction of the motor 200 , and the strip-shaped ribs 161 are plural and A plurality of strip-shaped ribs 161 are arranged at intervals along the circumferential direction of the mounting plate 160 .
