In the embodiments of the present application, "at least one" refers to one or more, and "more" refers to two or more.

[0034] It should be noted that the “at…” in the embodiments of the present application may be the instant when a certain situation occurs, or may be a period of time after the occurrence of a certain situation, and the embodiments of the present application do not specifically limit this.

[0035] With the continuous development of new energy vehicle technology and the continuous enrichment of vehicle application scenarios, electric drive axles with power take-offs in electric heavy-duty trucks are becoming increasingly important.

[0036] As a new type of automobile drive system, the electric drive axle converts the traditional internal combustion engine drive into an electric motor drive, 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 that extracts power from the vehicle's power system and transmits it to external equipment. It is widely used in special vehicles such as dump trucks, thereby realizing the special functions of the vehicle and enriching the vehicle's application scenarios. For electric heavy-duty trucks, the power take-off is usually integrated on the electric drive axle to enrich the application scenarios of electric heavy-duty trucks.

[0038] For an electric drive axle with a power take-off, the power take-off housing of the electric drive axle is an important part of the power take-off and has sealing and supporting functions. The power take-off housing of the electric drive axle can be sealed to the power take-off and the housing of the electric drive axle; after the power take-off obtains power from the electric drive axle, it needs to transfer the power to the oil pump through the transmission shaft of the power take-off or other connection methods, thereby driving the hydraulic oil in the oil pump to work and realize the special functions of the vehicle such as the lifting and unloading functions of the dump bucket. Therefore, the power take-off housing of the electric drive axle also needs to realize the support function of the oil pump.

[0039] When the existing electric drive axle power take-off housing realizes the support and fixation function of the power take-off and the oil pump, the support and fixation of the oil pump, the power take-off and the electric drive axle are generally realized by connecting bolts. However, since 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, the vibration of the oil pump, the power take-off and the electric drive axle on the electric drive axle power take-off housing is relatively large. Under long-term working vibration, the connecting bolts are easy to fall off and deform, causing the supported and fixed oil pump to fall and be damaged, thereby failing to realize the corresponding special functions of the vehicle, reducing the reliability of the oil pump.

[0040] In view of this, an embodiment of the present application provides a power take-off housing that can be used in the field of heavy-duty commercial vehicles, aiming to solve the above technical problems of the prior art. Based on the integrally formed joint surface and arc ring cover, the power take-off and the electric drive axle are fixed on both sides of the joint surface, the power take-off and the oil pump are preliminarily fixed by the first boss provided on the arc ring cover, and a second boss is provided on the joint surface to connect the support device, and the oil pump is further supported by the steel plate and rubber block in the support device. Since the rubber block can absorb the vibration energy generated by the working environment, it can effectively reduce the vibration of the oil pump relative to the electric drive axle, thereby avoiding the premature failure of the connecting bolts due to the support and fixation of the oil pump only by the connecting bolts, causing the oil pump to fall and be damaged, thereby improving the reliability of the oil pump.

[0041] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0042] Figure 1 A schematic diagram of a single-side structure of a power take-off housing provided in an embodiment of the present application Figure 1 ,like Figure 1 As shown, the power take-off housing 100 includes: a joint surface 101 and an arc ring cover 102, the arc ring cover 102 is perpendicular to the joint surface 101, and the joint surface 101 and the 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 joint surface 101 through the bolt holes on the joint surface 101. A first boss 110 with a through-hole structure is provided on the 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. A second boss 111 is provided on the joint surface 101.

[0044] Specifically, the joint surface 101 is a polygon, and multiple bolt holes are evenly arranged on the polygonal joint surface 101, and the multiple bolt holes on the joint surface 101 are used to connect the electric drive axle housing and the power take-off 200. The power take-off 200 is based on the first boss 110 and is arranged on the outer side of the joint surface 101 in the power take-off housing 100, that is, the single-sided structure schematic diagram Figure 1 In the current side shown, the electric drive axle in the electric drive axle housing is arranged on the inner side of the joint surface 101 in the power take-off housing 100, that is, the single-side structure schematic diagram Figure 1 The other side is shown.

[0045] The circular arc ring cover 102 is used to cover the transmission gear for transmitting power, and the power take-off 200 can be fixed by the first boss 110 provided on the circular arc ring cover 102 .

[0046] Furthermore, a cylindrical ring cover 103 is provided on the arc ring cover 102, and the cylindrical ring cover 103 is used to install an oil filter for filtering lubricating oil, wherein the oil filter is provided with a through hole, which is connected to the electric drive bridge cavity, so that the filtered lubricating oil enters the electric drive bridge through the through hole to lubricate the gear components of each level therein.

[0047] Furthermore, an oil collecting groove 104 is provided inside the circular arc ring cover 102 for collecting the lubricating oil thrown in.

[0048] Specifically, when the electric drive axle transmits power through the transfer gear covered by the arc ring cover 102, the transfer gear rotates in the arc ring cover 102. When the transfer gear rotates, the lubricating oil on the gear will splash onto the arc ring cover 102. The lubricating oil splashed onto the arc ring cover 102 is collected by the oil collecting tank in the arc ring cover 102. After the oil collecting tank collects a preset amount of lubricating oil, the collected lubricating oil is transported to the oil filter in the cylindrical ring cover 103 through the oil transfer 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 and works again.

[0049] Furthermore, a detachable end cover connecting flange 105 is provided on the arc side of the arc ring cover 102 for connecting the end cover of the power take-off housing 100 .

[0050] Furthermore, divergent ribs 106 are provided on the arc ring cover 102 , and the divergent ribs 106 extend from the first boss 110 to the end cover connecting flange 105 .

[0051] Specifically, a detachable shell end cover connecting flange 105 is provided on the other side of the arc ring cover 102, which is used to connect the end cover of the power take-off shell 100; the divergent ribs 106 arranged on the arc ring cover 102 increase the strength of the power take-off shell 100, and at the same time can dissipate the heat generated by the power take-off 200 and the electric drive bridge.

[0052] Furthermore, a third boss 107 is provided on the arc ring cover 102 at a position close to the mating surface 101 , and the third boss 107 is used to fix an oil temperature sensor, which can obtain the temperature of the hydraulic oil in the surrounding oil pump 300 and send the obtained hydraulic oil temperature to the processor, wherein the oil temperature sensor is threadedly connected to the third boss 107 .

[0053] Among them, a protective plate rib 108 cast integrally with the power take-off housing 100 is arranged on the outer side of the third boss 107. The protective plate rib 108 is higher than the third boss 107 and is rectangular.

[0054] Specifically, the strength of the power take-off housing 100 can be enhanced by protecting the plate ribs 108 , while protecting the oil temperature sensor on the third boss 107 to prevent the oil temperature sensor from being bumped and its wiring harness from being loosened due to working vibration.

[0055] The embodiment of the present application provides a power take-off housing, based on the integrally formed joint surface 101 and the arc ring cover 102, to fix the power take-off 200 and the electric drive axle on both sides of the joint surface 101, and preliminarily fix the power take-off 200 and the oil pump 300 through the first boss 110 provided on the arc ring cover 102, and a second boss 111 is provided on the joint surface 101 to connect the support device 500, and further fit and support 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 by 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 bolts due to the support and fixation of the oil pump 300 only by the connecting bolts, causing the oil pump 300 to fall and be damaged, thereby improving the reliability of the oil pump 300.

[0056] Figure 2 A schematic diagram of a single-side structure of a power take-off housing provided in an embodiment of the present application Figure 2 In this embodiment, Figure 1 Based on the embodiment, the inner side of the power take-off housing 100 is described in detail, such as Figure 2 As shown, a plurality of positioning pin holes 109 located on the same straight line are provided on the side of the power take-off housing 100 where the electric drive axle is located, that is, the inner side, for fixing the front reduction housing.

[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 the present 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 front reducer housing and the power take-off housing 100 can be directly positioned by the positioning pin holes 109 set on a straight line, which has a better positioning effect and higher gear transmission accuracy.

[0059] The embodiment of the present application provides a power take-off housing, based on the integrally cast joint surface 101 and the arc ring cover 102, to fix the power take-off 200 and the electric drive axle on both sides of the joint surface 101, and preliminarily fix the power take-off 200 and the oil pump 300 through the first boss 110 provided on the arc ring cover 102, and a second boss 111 is provided on the joint surface 101 to connect the support device 500, and further fit and support 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 by 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 bolts due to the support and fixation of the oil pump 300 only by the connecting bolts, causing the oil pump 300 to fall and be damaged, thereby improving the reliability of the oil pump 300.

[0060] Figure 3 A partial structural diagram of the power take-off housing provided in this application, such as Figure 3 As shown, in this embodiment Figure 2 Based on the embodiment, the power take-off housing is described in detail, and 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 filtering.

[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 transfer 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 in the arc ring cover 102 rotates, the lubricating oil on the gear will splash onto the arc ring cover 102. At this time, the oil collecting groove 104 in the arc ring cover 102 collects the lubricating oil splashed onto the arc ring cover 102. Since a connected oil delivery channel 112 is provided between the oil collecting groove 104 and the oil filter, the oil collecting groove 104 transports the collected lubricating oil to the oil filter in the cylindrical ring cover 103 through the oil delivery channel 112, and the oil filter filters the collected lubricating oil.

[0063] The embodiment of the present application provides a power take-off housing, based on the integrally cast joint surface 101 and the arc ring cover 102, to fix the power take-off 200 and the electric drive axle on both sides of the joint surface 101, and preliminarily fix the power take-off 200 and the oil pump 300 through the first boss 110 provided on the arc ring cover 102, and a second boss 111 is provided on the joint surface 101 to connect the support device 500, and further fit and support 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 by 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 bolts due to the support and fixation of the oil pump 300 only by the connecting bolts, causing the oil pump 300 to fall and be damaged, thereby improving the reliability of the oil pump 300.

[0064] Figure 4 This is a schematic diagram of the structure of the oil collecting tank provided in the embodiment of the present application. Figure 3 Based on the embodiment, the structure of the oil collecting tank 104 in the power take-off housing 100 is described in detail. Figure 4 As shown, the first end of the oil collecting groove 104 is larger than the second end, and the first end is an end connected to the oil delivery 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 arc ring cover 102 rotates inside the arc ring cover 102 .

[0066] Furthermore, when the transmission gear in the circular arc ring cover 102 rotates, the lubricating oil on the rotating gear will splash onto the circular arc ring cover 102 , and at this 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] Furthermore, after the oil collecting tank collects a preset amount of lubricating oil, the collected lubricating oil is transported to the oil filter in the cylindrical ring cover 103 through the oil delivery channel 112, and the collected lubricating oil is filtered by the oil filter. The oil filter is provided with an oil outlet for transporting the lubricating oil into the cavity of the electric drive axle, so that the filtered lubricating oil reaches the cavity of the electric drive axle and lubricates the gear components again.

[0068] Furthermore, when the oil collecting tank 104 collects lubricating oil, since the size of the first end of the oil collecting tank 104 is larger than the size of the second end, that is, the oil collecting tank 104 is semicircular, and the top semicircular diameter of the oil collecting tank 104 is smaller than the bottom semicircular diameter, the semicircular oil collecting tank 104 is compared with the existing cylindrical oil collecting tank 104. When the amount of lubricating oil collected is the same, the semicircular oil collecting tank 104 collects a higher level of lubricating oil, and more lubricating oil passes through the oil filter.

[0069] The embodiment of the present application provides a power take-off housing, based on the integrally cast joint surface 101 and the arc ring cover 102, to fix the power take-off 200 and the electric drive axle on both sides of the joint surface 101, and preliminarily fix the power take-off 200 and the oil pump 300 through the first boss 110 provided on the arc ring cover 102, and a second boss 111 is provided on the joint surface 101 to connect the support device 500, and further fit and support 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 by 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 bolts due to the support and fixation of the oil pump 300 only by the connecting bolts, causing the oil pump 300 to fall and be damaged, thereby improving the reliability of the oil pump 300.

[0070] Figure 5 The overall structure diagram of the power take-off housing provided in the embodiment of the present application is shown in FIG. 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, the second boss 111 is connected to the supporting device 500 , and the supporting device 500 includes: a steel plate 501 and a rubber block 502 , and the oil pump 300 is in contact with the rubber block 502 .

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

[0072] Specifically, a second boss 111 is provided on one side of the arc ring cover 102, wherein the second boss 111 is a square structure, and a through-hole structure is provided 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, such as four threaded holes, i.e., mounting holes, are provided around the second boss 11. Based on the plurality of threaded holes, the power take-off 200 and the oil pump 300 successively pass through the oil pump 300 and the power take-off 200 through the studs 400, and cooperate with the plurality of threaded holes provided 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] Furthermore, the steel plate 501 is located under the rubber block 502 and is used to support the rubber block 502 .

[0074] Specifically, since the second boss 111 disposed on the circular arc ring cover 102 is connected to the supporting device 500 via bolts, the oil pump 300 is fixedly connected to the circular arc ring cover 102 on the power take-off housing 100 via the supporting device 500 .

[0075] Furthermore, in the support device 500 including the steel plate 501 and the rubber block 502, the bottom of the oil pump 300 is fitted with the rubber block 502 in the support device 500, so in addition to the first boss 110 supporting the oil pump 300, the tightly fitted rubber block 502 provides another support for the oil pump 300. Since the power take-off 200 is located on the electric drive axle and is an unsprung mass, it has a large vibration. Therefore, by using the support device 500 including the rubber block 502, the vibration of the oil pump 300 relative to the electric drive axle can be effectively reduced, and the premature failure of the connecting bolts can be avoided.

[0076] The embodiment of the present application provides a power take-off housing, based on the integrally cast joint surface 101 and the arc ring cover 102, to fix the power take-off 200 and the electric drive axle on both sides of the joint surface 101, and preliminarily fix the power take-off 200 and the oil pump 300 through the first boss 110 provided on the arc ring cover 102, and a second boss 111 is provided on the joint surface 101 to connect the support device 500, and further fit and support 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 by 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 bolts due to the support and fixation of the oil pump 300 only by the connecting bolts, causing the oil pump 300 to fall and be damaged, thereby improving the reliability of the oil pump 300.

[0077] An embodiment of the present application also provides a vehicle, comprising the above-mentioned power take-off housing.
