It can be understood by those skilled in the art that "first", "second", and the like do not limit the quantity and execution sequence, and "first", "second", and the like do not necessarily mean different.

Any embodiment or design scheme described as "exemplary" or "for example" in the present application should not be interpreted as more preferred or more advantageous than other embodiments or design schemes. Rather, "exemplary" or "for example" is used to present the relevant concept in a specific manner. In the embodiments of the present application, "at least one" means one or more, and "multiple" means two or more.

[0034] It should be noted that "at the time of" in the embodiments of the present application can be at the moment when a certain condition occurs, or within a period of time after the occurrence of a certain condition, which is not specifically limited in the embodiments of the present application.

[0035] With the continuous development of new energy vehicle technology and the continuous enrichment of vehicle application scenarios, the electric drive axle with a power take-off in an electric heavy truck is also increasingly important.

[0036] As a new type of automobile driving system, the electric drive axle changes the traditional internal combustion engine driving into electric motor driving, and arranges the motor, reducer, differential, and other components in a common electric drive axle housing to form a compact power unit.

[0037] The power take-off is a device for extracting power from the power system of a vehicle and transmitting it to external equipment. It is widely used in special vehicles such as dump trucks to realize special functions of the vehicle and enrich the vehicle application scenarios. For an electric heavy truck, the power take-off is usually integrated on the electric drive axle to realize the enrichment of the application scenarios of the electric heavy truck.

[0038] For the electric drive axle with a power take-off, the electric drive axle power take-off housing, as an important component of the power take-off, has sealing and supporting functions. The electric drive axle power take-off housing can realize the sealing of the power take-off and the sealing of the electric drive axle housing; after the power take-off obtains power from the electric drive axle, it also needs to transmit power to the oil pump through the transmission shaft or other connection mode of the power take-off, so as to drive the hydraulic oil in the oil pump to work and realize the special functions of the vehicle such as lifting and unloading of the self-unloading hopper. Therefore, the electric drive axle power take-off housing also needs to realize the supporting function of the oil pump.

[0039] The existing electric drive axle power take-off shell generally realizes the support and fixing function of the power take-off and the oil pump by connecting bolts, but the oil pump, the power take-off and the electric drive axle belong to the unsprung mass of the vehicle, that is, the oil pump, the power take-off and the electric drive axle are supported by elastic elements such as springs and shock absorbers, so that the vibration of the oil pump, the power take-off and the electric drive axle on the electric drive axle power take-off shell is large, and under the long-time working vibration, the connecting bolts are easy to fall off and deform, thereby causing the supported oil pump to fall off and damage, so that the corresponding special function of the vehicle cannot be realized, and the reliability of the oil pump is reduced.

[0040] Therefore, the embodiment of the present application provides a power take-off shell which can be used in the field of heavy commercial vehicles and aims to solve the above technical problems of the prior art. Based on the integrated combination surface and the circular arc ring cover, the power take-off and the electric drive axle are fixed on both sides of the combination surface, the first boss provided on the circular arc ring cover is used to preliminarily fix the power take-off and the oil pump, and the second boss is arranged on the combination surface to connect the support device, and the steel plate and the rubber block in the support device are further used to support the oil pump. Since the rubber block can absorb the vibration energy generated in the working environment, the vibration of the oil pump relative to the electric drive axle can be effectively reduced, thereby avoiding the premature failure of the connecting bolts caused by the support and fixing of the oil pump only through the connecting bolts, the falling and damage of the oil pump, and the improvement of the reliability of the oil pump.

[0041] The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be described in detail in the following specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described again in some embodiments. The embodiments of the present application will be described below with reference to the drawings.

[0042] Figure 1 The single-sided structure of the power take-off shell provided by the embodiment of the present application Figure One As shown in Figure 1 The power take-off shell 100 includes a combination surface 101 and a circular arc ring cover 102, the circular arc ring cover 102 is perpendicular to the combination surface 101, and the combination surface 101 and the circular arc ring cover 102 are integrally formed.

[0043] The power take-off 200 and the electric drive axle are fixed on both sides of the combination surface 101 through the bolt holes on the combination surface 101, the first boss 110 with a through hole structure is arranged on the circular arc ring cover 102, the power take-off 200 is connected to the transmission mechanism of the electric drive axle through the through hole structure, and the second boss 111 is arranged on the combination surface 101.

[0044] Specifically, the joint surface 101 is a polygon, and a plurality of bolt holes are uniformly arranged on the joint surface 101. The electric drive axle housing and the power takeoff 200 are connected through the plurality of bolt holes on the joint surface 101. The power takeoff 200 is arranged on the outer side of the joint surface 101 in the power takeoff housing 100 based on the first boss 110, that is, the single-sided structure is shown on one side Figure One The electric drive axle in the electric drive axle housing is arranged on the inner side of the joint surface 101 in the power takeoff housing 100, that is, the single-sided structure is shown on the other side Figure One

[0045] The circular arc cover 102 is used to cover the transmission gear that transmits power, and the first boss 110 arranged on the circular arc cover 102 is used to fix the power takeoff 200.

[0046] Further, the circular arc cover 102 is provided with a cylindrical cover 103 for installing an oil filter for filtering lubricating oil. The oil filter is provided with a through hole in communication with the electric drive axle cavity, so that the filtered lubricating oil enters the electric drive axle to lubricate the gear components therein through the through hole.

[0047] Further, the circular arc cover 102 is provided with an oil collecting groove 104 inside for collecting the splashed lubricating oil.

[0048] Specifically, when the electric drive axle transmits power through the transmission gear covered by the circular arc cover 102, the transmission gear rotates in the circular arc cover 102. When the transmission gear rotates, the lubricating oil on the gear splashes onto the circular arc cover 102. The splashed lubricating oil on the circular arc cover 102 is collected by the oil collecting groove in the circular arc cover 102. After the oil collecting groove collects a predetermined amount of lubricating oil, the collected lubricating oil is transported to the oil filter in the cylindrical cover 103 through the oil conveying channel. The collected lubricating oil is filtered by the oil filter, so that the filtered lubricating oil reaches the cavity of the electric drive axle to work again.

[0049] Further, the circular arc side of the circular arc cover 102 is provided with a detachable end cap connecting flange 105 for connecting the end cap of the power takeoff housing 100.

[0050] Further, the circular arc cover 102 is provided with a diverging rib 106 extending from the first boss 110 to the end cap connecting flange 105.

[0051] ​Specifically, the other side of the circular arc ring cover 102 is provided with a detachable shell end cover connecting flange 105 for connecting the end cover of the power takeoff shell 100; the divergent ribs 106 provided on the circular arc ring cover 102 increase the strength of the power takeoff shell 100, and can also dissipate the heat generated by the power takeoff 200 and the electric drive axle.

[0052] Further, the third boss 107 is provided on the circular arc ring cover 102 close to the joint surface 101, and the third boss 107 is used for fixing an oil temperature sensor. The oil temperature sensor can obtain the temperature of the hydraulic oil in the oil pump 300 around it, and send the obtained hydraulic oil temperature to the processor. The oil temperature sensor is threadedly connected to the third boss 107.

[0053] The third boss 107 is provided with a protection plate rib 108 integrally cast with the power takeoff shell 100 outside the third boss 107. The protection plate rib 108 is higher than the third boss 107, and the protection plate rib 108 is rectangular.

[0054] Specifically, the protection plate rib 108 can strengthen the strength of the power takeoff shell 100, and protect the oil temperature sensor on the third boss 107 from being bumped and the wire harness from being loosened due to working vibration.

[0055] The power takeoff shell provided by the embodiment of the present application fixes the power takeoff 200 and the electric drive axle on both sides of the joint surface 101 based on the integrally formed joint surface 101 and the circular arc ring cover 102. The first boss 110 provided on the circular arc ring cover 102 is used to preliminarily fix the power takeoff 200 and the oil pump 300, and the second boss 111 is provided on the joint surface 101 to connect the supporting device 500. The steel plate 501 and the rubber block 502 in the supporting device 500 further adhere to support the oil pump 300. Since the rubber block 502 can absorb the vibration energy generated in the working environment, it can effectively reduce the vibration of the oil pump 300 relative to the electric drive axle, thereby avoiding the premature failure of the connecting bolt due to the support and fixation of the oil pump 300 only through the connecting bolt, causing the oil pump 300 to fall and be damaged, and further improving the reliability of the oil pump 300.

[0056] Figure 2 The single-sided structure of the power takeoff shell provided by the embodiment of the present application is shown in Figure Two The embodiment is based on Figure 1 The inner side of the power takeoff shell 100 is described in detail based on the embodiment, as shown in Figure 2 The side of the power takeoff shell 100 where the electric drive axle is located, i.e. the inner side, is provided with a plurality of positioning pin holes 109 located on the same straight line, for fixing the front reduction shell.

[0057] Specifically, a plurality of preset positioning pin holes 109 are provided on the inner side of the power take-off housing 100 , that is, on the inner side of the joint surface 101 in the power take-off housing 100 . In this embodiment, four positioning pin holes 109 are provided on the inner side of the power take-off housing 100 .

[0058] Among them, each positioning pin hole 109 is located on the inner center plane of the power take-off housing 100, and each positioning pin hole 109 is on a straight line, which is used to achieve positioning with the front reducer housing. By setting the positioning pin holes 109 on a straight line, the positioning with the front reducer housing can be achieved without going through the intermediate piece of the bridge housing. Instead, the positioning pin holes 109 set on a straight line can achieve direct positioning of the front reducer housing and the power take-off housing 100, resulting in better positioning effect and higher gear transmission accuracy.

[0059] The power take-off housing provided in the present application is based on an integrally cast joint surface 101 and an arc-shaped annular cover 102. The power take-off 200 and the electric drive axle are fixed to either side of the joint surface 101. A first boss 110 provided on the arc-shaped annular cover 102 initially secures the power take-off 200 and the oil pump 300. A second boss 111 is provided on the joint surface 101 to connect to the support device 500. The oil pump 300 is further supported by a steel plate 501 and a rubber block 502 within the support device 500. Because the rubber block 502 can absorb vibration energy generated by the working environment, it can effectively reduce vibration of the oil pump 300 relative to the electric drive axle. This avoids premature failure of the connecting bolts that can cause the oil pump 300 to fall and be damaged when the oil pump 300 is supported and fixed solely by connecting bolts, thereby improving the reliability of the oil pump 300.

[0060] Figure 3 This is a partial structural diagram of the power take-off housing provided in this application, as shown in Figure 3 As shown, this embodiment Figure 2 Based on the embodiment, the power take-off housing is described in detail, the oil collecting tank 104 and the oil filter are connected through the oil delivery channel 112, which is used to deliver the lubricating oil collected in the oil collecting tank 104 to the oil filter for filtration.

[0061] Specifically, when the transmission mechanism of the electric drive axle transmits power to the power take-off 200 through the through-hole structure of the first boss 110 , the transmission gear covered by the arc ring cover 102 rotates inside the arc ring cover 102 to transmit the power of the electric drive axle to the power take-off 200 .

[0062] When the transmission gear rotates in the circular arc ring cover 102, the lubricating oil on the gear will splash onto the circular arc ring cover 102, at which time the oil collecting groove 104 in the circular arc ring cover 102 collects the lubricating oil splashed onto the circular arc ring cover 102. Since the oil collecting groove 104 and the oil filter are provided with the oil conveying channel 112 in communication, the oil collecting groove 104 will transport the collected lubricating oil to the oil filter in the cylindrical ring cover 103 through the oil conveying channel 112, and the oil filter filters the collected lubricating oil.

[0063] The power take-off housing provided by the embodiment of the application is fixed with the power take-off 200 and the electric drive axle on both sides of the combined surface 101 based on the combined surface 101 and the circular arc ring cover 102 integrally formed by casting, and the power take-off 200 and the oil pump 300 are preliminarily fixed by the first boss 110 provided on the circular arc ring cover 102, and the second boss 111 is provided on the combined surface 101 to connect the supporting device 500, and the steel plate 501 and the rubber block 502 in the supporting device 500 further adhere to support the oil pump 300. Since the rubber block 502 can absorb the vibration energy generated in the working environment, the vibration of the oil pump 300 relative to the electric drive axle can be effectively reduced, so that the early failure of the connecting bolt caused by the support and fixation of the oil pump 300 by only the connecting bolt is avoided, the oil pump 300 is prevented from falling and being damaged, and the reliability of the oil pump 300 is improved.

[0064] Figure 4 The structure diagram of the oil collecting groove provided by the embodiment of the application is shown in the embodiment. Figure 3 The structure of the oil collecting groove 104 in the power take-off housing 100 is described in detail based on the embodiment. Figure 4 As shown in the figure, the first end of the oil collecting groove 104 is larger than the second end, and the first end is connected to one end of the oil conveying channel 112.

[0065] Specifically, when the transmission mechanism of the electric drive axle transmits power to the power take-off 200, the transmission gear covered by the circular arc ring cover 102 rotates in the circular arc ring cover 102.

[0066] Further, when the transmission gear rotates in the circular arc ring cover 102, the lubricating oil on the rotating gear will splash onto the circular arc ring cover 102, at which time the oil collecting groove 104 in the circular arc ring cover 102 collects the lubricating oil splashed onto the circular arc ring cover 102.

[0067] Further, after the oil collecting groove collects a preset amount of lubricating oil, the oil collecting groove transports the collected lubricating oil to the oil filter in the cylindrical ring cover 103 through the oil conveying channel 112, filters the collected lubricating oil through the oil filter, and the oil filter is provided with an oil outlet for conveying the lubricating oil to the cavity of the electric drive axle, so that the filtered lubricating oil is used to lubricate the gear components in the cavity of the electric drive axle again.

[0068] Further, when collecting lubricating oil, due to the first end of the oil collecting groove 104 being larger than the second end, that is, the oil collecting groove 104 is semicircular, the top semicircle diameter of the oil collecting groove 104 is smaller than the bottom semicircle diameter, so that the semicircular structure of the oil collecting groove 104 has a higher lubricating oil liquid level and more lubricating oil passing through the oil filter compared with the existing cylindrical structure of the oil collecting groove 104 when the collected amount of lubricating oil is the same.

[0069] The power take-off housing provided by the embodiment of the application fixes the power take-off 200 and the electric drive axle on the two sides of the combined surface 101 based on the combined surface 101 and the circular arc ring cover 102 formed by integral casting, preliminarily fixes the power take-off 200 and the oil pump 300 through the first boss 110 arranged on the circular arc ring cover 102, and is provided with the second boss 111 on the combined surface 101 to connect the supporting device 500, and further supports the oil pump 300 through the steel plate 501 and the rubber block 502 in the supporting device 500. Since the rubber block 502 can absorb vibration energy generated in the working environment, the vibration of the oil pump 300 relative to the electric drive axle can be effectively reduced, so that the early failure of the connecting bolt caused by the support and fixation of the oil pump 300 through only the connecting bolt is avoided, the oil pump 300 is prevented from falling and being damaged, and the reliability of the oil pump 300 is improved.

[0070] Figure 5 The overall structure diagram of the power take-off housing provided by the embodiment of the application is shown in Figure 4 Based on the embodiment, the supporting device 500 of the power take-off housing 100 is further described in detail. Figure 5 As shown in the figure, the second boss 111 connects the supporting device 500, and the supporting device 500 includes the steel plate 501 and the rubber block 502, and the oil pump 300 is attached to the rubber block 502.

[0071] Further, the first boss 110 is provided with mounting holes around the first boss 110 for fixing the power take-off 200 and the oil pump 300.

[0072] Specifically, the second boss 111 is arranged on one side of the circular arc ring cover 102, wherein the second boss 111 is a square structure, a through hole structure is arranged in the middle of the second boss 111, the power take-off 200 is connected to the electric drive axle transmission mechanism through the through hole structure of the second boss 111 and transmits power. A plurality of threaded holes, for example, four threaded holes, are arranged around the second boss 11, that is, mounting holes. Based on the plurality of threaded holes, the power take-off 200 and the oil pump 300 pass through the oil pump 300 and the power take-off 200 in sequence through the stud 400, and are matched with the plurality of threaded holes arranged on the second boss 11, so that the power take-off 200 and the oil pump 300 are connected to the power take-off housing 100.

[0073] Further, the steel plate 501 is located below the rubber block 502 to support the rubber block 502.

[0074] Specifically, the second boss 111 arranged on the circular-arc ring cover 102 supports the oil pump 300 through the support device 500, so that the oil pump 300 is fixedly connected to the circular-arc ring cover 102 on the power take-off housing 100 through the support device 500.

[0075] Further, in the support device 500 including the steel plate 501 and the rubber block 502, the bottom of the oil pump 300 is closely attached to the rubber block 502 in the support device 500, so that the closely attached rubber block 502 supports the oil pump 300 in addition to the support of the first boss 110 on the oil pump 300. Since the power take-off 200 is located on the electric drive axle and belongs to unsprung mass, the vibration is large, so that the support device 500 including the rubber block 502 can effectively reduce the vibration of the oil pump 300 relative to the electric drive axle, and avoid the premature failure of the connecting bolt.

[0076] The power take-off housing provided by the embodiment of the present application fixes the power take-off 200 and the electric drive axle on both sides of the combined surface 101 based on the integrally cast combined surface 101 and the circular-arc ring cover 102, preliminarily fixes the power take-off 200 and the oil pump 300 through the first boss 110 arranged on the circular-arc ring cover 102, and arranges the second boss 111 on the combined surface 101 to connect the support device 500, and further supports the oil pump 300 through the steel plate 501 and the rubber block 502 in the support device 500. Since the rubber block 502 can absorb the vibration energy generated in the working environment, the vibration of the oil pump 300 relative to the electric drive axle can be effectively reduced, so that the premature failure of the connecting bolt due to the support and fixation of the oil pump 300 through only the connecting bolt is avoided, the oil pump 300 is prevented from falling and being damaged, and the reliability of the oil pump 300 is improved.

[0077] The embodiment of the present application also provides a vehicle including the power take-off housing.
