Description

Technical Field

[0001] This invention relates to the field of hybrid power technology, and more specifically, to a modular electric drive lubrication and filtration assembly, an electric drive system, and a vehicle. Background Technology

[0002] Traditional lubrication and filtration systems often adopt an integrated structural design, with core components such as internal filters and oil pumps fixedly connected to the housing. This not only results in a large overall size and occupies a lot of equipment installation space, but also makes subsequent cleaning and replacement of filters and maintenance of oil pumps require disassembling the entire system, which is cumbersome and time-consuming. At the same time, the integrated structure makes it difficult to flexibly adjust the specifications of components according to the lubrication needs of different equipment, resulting in poor adaptability. Summary of the Invention

[0003] The main objective of this invention is to provide a modular electric drive lubrication and filtration assembly, an electric drive system, and a vehicle to solve the problems of large size and large installation space occupation of traditional integrated lubrication and filtration systems in the prior art.

[0004] To achieve the above objectives, according to one aspect of the present invention, a modular electric-driven lubrication and filtration assembly is provided, comprising: an oil pan located below a main housing and connected to the main housing; the main housing having a mounting cavity; the oil pan having an oil storage cavity communicating with the mounting cavity; a filter assembly located within the mounting cavity; the filter assembly being correspondingly disposed with the oil inlet of the oil storage cavity; the filter assembly being connected to one of the main housing and the oil pan, so that lubricating oil in the main housing enters the oil storage cavity and passes through the filter assembly; and an electric pump having a first oil inlet pipe and a second oil outlet pipe; one end of the first oil inlet pipe being connected to one of the filter assembly and the oil pan; the first oil inlet pipe communicating with the oil storage cavity; and the second oil outlet pipe communicating with the mounting cavity.

[0005] Furthermore, the modular electric drive lubrication and filtration assembly also includes: an oil drain plug, an oil drain port on the oil pan, and the oil drain plug being detachably located at the oil drain port.

[0006] Furthermore, the filter assembly includes: a filter body, which is correspondingly disposed with the oil inlet of the oil storage chamber, and the filter body is connected to one of the main housing and the oil pan; a connecting pipe, which is connected to the filter body, with a first end of the connecting pipe extending into the oil storage chamber, and a second end of the connecting pipe connected to one end of the first oil inlet pipe.

[0007] Furthermore, the filter assembly also includes a magnet, which includes at least one magnet connected to the filter body and is positioned corresponding to the oil inlet of the oil storage chamber.

[0008] Furthermore, the modular electric drive lubrication and filtration assembly also includes: a pressure filter, which is located inside the mounting cavity and is disposed on one side of the electric pump. The pressure filter is detachably connected to the oil pan. The pressure filter has a pressure filter cavity, the oil inlet port of which is connected to one end of the second oil outlet pipe, the pressure filter cavity is connected to the second oil outlet pipe, and the oil outlet port of which is connected to the mounting cavity.

[0009] Furthermore, the second oil outlet pipe is located above the first oil inlet pipe.

[0010] Furthermore, the modular electric drive lubrication and filtration assembly includes: a bypass oil outlet pipe located within the mounting cavity and above the oil pan, the bypass oil outlet pipe being spaced apart from the pressure filter and the electric pump, a first end of the bypass oil outlet pipe being connected to a second oil outlet pipe, and the bypass oil outlet pipe being connected to the mounting cavity; and a bypass valve located on the bypass oil outlet pipe, the bypass valve having a connection position for connecting the second oil outlet pipe to the mounting cavity via the bypass oil outlet pipe, and a disconnection position for disconnecting the second oil outlet pipe from the mounting cavity via the bypass oil outlet pipe.

[0011] Furthermore, the bypass oil outlet pipe is located above the second oil outlet pipe, and the bypass oil outlet pipe and the second oil outlet pipe are set at a preset angle.

[0012] According to another aspect of the present invention, an electric drive system is provided, including a modular electric drive lubrication and filtration assembly, wherein the modular electric drive lubrication and filtration assembly is the modular electric drive lubrication and filtration assembly described above.

[0013] According to another aspect of the present invention, a vehicle is provided, including an electric drive system, wherein the electric drive system is the electric drive system described above.

[0014] By applying the technical solution of this invention, the oil pan, filter assembly, and electric pump are separated and combined through modular design, which significantly reduces the overall system volume and installation space occupancy. The filter assembly can be connected to the main housing or oil pan independently, and the electric pump is connected to the filter assembly or oil pan and the mounting cavity through inlet and outlet oil pipes, respectively. This allows for filter cleaning and replacement and electric pump maintenance without disassembling the entire system, making operation more convenient and efficient. The independent connection method of each component also allows for flexible replacement of filter assemblies or electric pumps of appropriate specifications according to the lubrication requirements of different equipment, significantly improving the adaptability and versatility of the system.

[0022] Traditional lubrication filtration systems generally adopt an integrated structural design. Core components such as the filter screen (which filters impurities) and the oil pump (which powers the lubricating fluid) are directly connected to the system housing via welding or bolts. This design firstly results in a large overall system size, requiring more physical space during installation, and is particularly incompatible with compact production environments. Secondly, because the core components cannot be separated from the housing, subsequent maintenance requires disconnecting the system from the main unit and disassembling the entire lubrication filtration system from the equipment. This is not only cumbersome but also significantly extends equipment downtime and increases maintenance costs. Furthermore, the specifications of components in an integrated structure are fixed at the factory, making it impossible to flexibly change or adjust the parameters of core components such as the filter screen and oil pump according to the different requirements of different equipment for lubricating fluid flow rate, filtration accuracy, and operating pressure. This results in poor system adaptability to different application scenarios and difficulty in cross-equipment reuse.

[0023] This application provides a modular electric drive lubrication and filtration assembly, such as... Figure 1 and Figure 2 As shown, it includes: an oil pan 30, located below the main housing 10 and connected to the main housing 10; the main housing 10 has an installation cavity; the oil pan 30 has an oil storage cavity 301, which is connected to the installation cavity; a filter assembly 40, located inside the installation cavity; the filter assembly 40 is correspondingly arranged with the oil inlet of the oil storage cavity 301; the filter assembly 40 is connected to one of the main housing 10 and the oil pan 30, so that the lubricating oil in the main housing 10 enters the oil storage cavity 301 and passes through the filter assembly 40; and an electric pump 50, having a first oil inlet pipe 501 and a second oil outlet pipe 502; one end of the first oil inlet pipe 501 is connected to one of the filter assembly 40 and the oil pan 30; the first oil inlet pipe 501 is connected to the oil storage cavity 301; and the second oil outlet pipe 502 is connected to the installation cavity.

[0024] In this embodiment, by adopting a separate connection design between the oil pan 30 and the main housing 10, the limitations of the traditional integrated structure are broken. This not only allows for flexible adjustment of the assembly positions of the two according to the installation space, reducing the overall layout difficulty, but also facilitates the separate disassembly of the oil pan 30 to clean or maintain the oil storage chamber 301 without disassembling the entire assembly. Secondly, the filter assembly 40 is independently set in the mounting cavity of the main housing 10 and is only connected to one of the main housing 10 or the oil pan 30. When replacing or cleaning the filter, there is no need to move other components such as the electric pump 50; the filter assembly can be directly cleaned. The operation of component 40 is simple, greatly simplifying the maintenance process. Finally, the electric pump 50 is precisely connected to the filter assembly 40 or the oil pan 30 through the first oil inlet pipe 501 and the second oil outlet pipe 502 is connected to the mounting cavity, forming an independent and efficient lubricating oil delivery path. This ensures that the lubricating oil in the oil storage chamber 301 can directly enter the electric pump 50 after being filtered by the filter assembly 40, improving filtration and delivery efficiency. It also allows for the replacement of the electric pump 50 or filter assembly 40 of appropriate specifications according to the lubrication needs of different equipment, without the need to replace the entire assembly, significantly enhancing the adaptability and reusability of the assembly.

[0025] Furthermore, the modular electric-driven lubrication and filtration assembly also includes an oil drain plug 60. The oil pan 30 is provided with an oil drain port, and the oil drain plug 60 is detachably located at the oil drain port. The pre-installed oil drain port on the oil pan 30, in conjunction with the detachable oil drain plug 60, allows for easy replacement of the lubricating oil in the oil reservoir 301 or cleaning of residual impurities without disassembling the oil pan 30 or the entire assembly. Simply unscrew the oil drain plug 60 to quickly drain the old oil or remove impurities through the oil drain port, greatly simplifying the operation. At the same time, the detachable design of the oil drain plug 60 facilitates individual inspection or replacement, avoiding oil leakage caused by poor sealing due to aging of the plug, and does not affect the connection stability between the oil pan 30 and the main housing 10. It also eliminates the need to affect the normal operation of core components such as the filter assembly 40 and the electric pump 50, reducing maintenance costs and minimizing overall downtime of the assembly, further enhancing the flexibility and efficiency of the modular design.

[0026] Specifically, the filter assembly 40 includes: a filter body 402, which is correspondingly disposed with the oil inlet of the oil storage chamber 301, and is connected to one of the main housing 10 and the oil pan 30; and a connecting pipe, which is connected to the filter body 402, with the first end of the connecting pipe extending into the oil storage chamber 301 and the second end of the connecting pipe connected to one end of the first oil inlet pipe 501.

[0027] In this embodiment, the filter body 402 is directly corresponding to the oil inlet of the oil storage chamber 301 and is connected to only one of the main housing 10 or the oil pan 30. This ensures that the lubricating oil in the main housing 10 can be completely filtered by the filter body 402 when it enters the oil storage chamber 301, improving the thoroughness of impurity filtration. It also maintains the flexibility of the modular design, so that when cleaning or replacing the filter body 402, there is no need to disassemble other components such as the oil pan 30 and the electric pump 50, making the operation more convenient. On the other hand, one end of the connecting pipe is connected to the filter body 402, and the other end... The first oil inlet pipe 501, which extends into the oil storage chamber 301 and connects to the electric pump 50, forms a precise oil passage from the filter body 402 to the oil storage chamber 301 and then to the electric pump 50. This not only prevents unfiltered lubricating oil from directly entering the electric pump 50 and causing contamination, but also achieves oil passage guidance through an independent connecting pipe, without relying on the internal structure of the main housing 10 or the oil pan 30. If the oil passage parameters need to be adjusted later, the connecting pipe of the appropriate specification can be replaced separately without modifying the filter body 402 or the electric pump 50, further enhancing the adaptability and maintenance convenience of the components.

[0028] Furthermore, the filter assembly 40 also includes a magnet 401, which includes at least one magnet 401 connected to the filter body 402. The magnet 401 is positioned corresponding to the oil inlet of the oil storage chamber 301. The direct connection of at least one magnet 401 to the filter body 402 and its corresponding positioning to the oil inlet of the oil storage chamber 301 ensures that the lubricating oil in the main housing 10 flows through the area of ​​the magnet 401 before entering the oil storage chamber 301 and being filtered by the filter body 402. The magnet 401 actively adsorbs metal debris mixed in the lubricating oil, significantly reducing the probability of metal impurities clogging the filter body 402, extending the filter's service life, and preventing metal debris from entering the subsequent connecting pipe and the first oil inlet pipe 501 of the electric pump 50, thus reducing wear on core components such as the electric pump 50.

[0029] In this embodiment, the modular electric drive lubrication and filtration assembly further includes: a pressure filter 20, which is located in the mounting cavity and is disposed on one side of the electric pump 50. The pressure filter 20 is detachably connected to the oil pan 30. The pressure filter 20 has a pressure filter cavity 201. The oil inlet port of the pressure filter cavity 201 is connected to one end of the second oil outlet pipe 502. The pressure filter cavity 201 is connected to the second oil outlet pipe 502. The oil outlet port 202 of the pressure filter cavity 201 is connected to the mounting cavity.

[0030] The pressure filter 20 is located in the mounting cavity of the main housing 10 and is adjacent to the electric pump 50. It is directly connected to the second oil outlet pipe 502 of the electric pump 50 through the oil inlet port of the pressure filter cavity 201. It can perform secondary filtration on the lubricating oil delivered by the electric pump 50. Combined with the preliminary filtration of the filter screen assembly 40, it forms a "double purification" effect, which greatly improves the cleanliness of the lubricating oil and effectively prevents tiny impurities from entering the subsequent lubrication circuit and damaging the equipment. Secondly, the pressure filter 20 is detachably connected to the oil pan 30. When the pressure filter 20 needs to be replaced or maintained, it is not necessary to disassemble the electric pump 50, filter screen assembly 40 and other core components. It can be operated independently by directly separating its connection with the oil pan 30, which greatly simplifies the maintenance process. At the same time, the oil outlet port 202 of the pressure filter cavity 201 is directly connected to the mounting cavity, which can ensure that the clean lubricating oil after secondary filtration enters the mounting cavity quickly and smoothly to meet the subsequent lubrication needs. The independent cavity structure also avoids the backflow of filtered impurities, ensuring the stability and reliability of oil circuit delivery.

[0031] Specifically, the second oil outlet pipe 502 is located above the first oil inlet pipe 501. By utilizing the height difference to optimize the oil flow direction, the first oil inlet pipe 501 needs to draw lubricating oil from the oil storage chamber 301, and the second oil outlet pipe 502 needs to deliver the pressurized lubricating oil to the pressure filter 20. The vertical arrangement can use gravity to assist the first oil inlet pipe 501 in smoothly drawing oil, while avoiding the two pipes from intersecting at the same horizontal level, reducing oil circuit resistance, and ensuring a smoother delivery of lubricating oil from the oil storage chamber 301 to the electric pump 50 and then to the pressure filter 20.

[0032] Furthermore, the modular electric drive lubrication and filtration assembly includes: a bypass oil outlet pipe 602, located within the mounting cavity and above the oil pan 30, spaced apart from the pressure filter 20 and the electric pump 50, with a first end connected to a second oil outlet pipe 502 and in communication with the mounting cavity; and a bypass valve 601, located on the bypass oil outlet pipe 602, having a connection position for connecting the second oil outlet pipe 502 to the mounting cavity via the bypass oil outlet pipe 602, and a disconnect position for disconnecting the second oil outlet pipe 502 from the mounting cavity via the bypass oil outlet pipe 602.

[0033] Specifically, the bypass oil outlet pipe 602 is located above the second oil outlet pipe 502, and the bypass oil outlet pipe 602 and the second oil outlet pipe 502 are set at a preset angle. The bypass oil outlet pipe 602 is located inside the mounting cavity and above the oil pan 30, and is spaced apart from the pressure filter 20 and the electric pump 50. This avoids spatial interference with other components, and connects to the second oil outlet pipe 502 of the electric pump 50 at one end and to the mounting cavity at the other end. Secondly, the bypass valve 601 can flexibly switch between connected and disconnected positions. When the pressure filter 20 causes the main oil circuit pressure to be too high due to blockage or other problems, switching the bypass valve 601 to the connected position allows the oil in the second oil outlet pipe 502 to flow freely. The lubricating oil flows directly into the mounting cavity through the bypass oil outlet pipe 602, avoiding overload damage to the electric pump 50 and ensuring that the basic oil supply function of the lubrication system is not interrupted. When the pressure filter 20 is working normally, switching the bypass valve 601 to the off position ensures that all the lubricating oil flows through the pressure filter 20 for filtration, taking into account both oil circuit safety and oil cleanliness. At the same time, the independent bypass structure also facilitates the separate maintenance or replacement of the bypass oil outlet pipe 602 and bypass valve 601 without affecting the operation of the core components of the main oil circuit.

[0034] According to another specific embodiment of this application, an electric drive system is also provided, including a modular electric drive lubrication and filtration assembly, wherein the modular electric drive lubrication and filtration assembly is the modular electric drive lubrication and filtration assembly described above.

[0035] In this embodiment, the separate connection of the main housing 10 and oil pan 30, and the independent modular design of the filter assembly 40, electric pump 50, and pressure filter 20 allow the electric drive system to flexibly adjust the component layout according to its own installation space, without having to reserve too much extra space for the lubrication and filtration device, thus greatly optimizing the overall structural compactness of the system. Secondly, during system operation, the lubricating oil undergoes preliminary iron removal and filtration by the filter assembly 40, is delivered by the electric pump 50, and undergoes secondary purification by the pressure filter 20. Combined with the pressure protection mechanism of the bypass oil outlet pipe 602 and the bypass valve 601, it can ensure that the lubricating oil entering the core components of the electric drive system has high cleanliness and stable oil supply, effectively reducing component wear and extending the service life of the electric drive system.

[0036] According to another specific embodiment of this application, a vehicle is also provided, including an electric drive system, which is the electric drive system described above.

[0037] By adopting this embodiment, the vehicle equipped with the above-mentioned electric drive system further enhances the reliability, ease of maintenance, and economy of operation. Its advantages are mainly reflected in the following aspects: First, the modular electric drive lubrication and filtration components integrated in the electric drive system can ensure that the core components of the electric drive system always receive a clean and stable supply of lubricating oil through the dual filtration of the filter assembly 40 and the pressure filter 20, as well as the pressure protection of the bypass oil outlet pipe 602 and the bypass valve 601. This effectively reduces the risk of electric drive system failure during vehicle operation and improves the smoothness and durability of the vehicle's power output.

[0038] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects: an engine drive mode in which the engine is connected to the ring gear or planetary carrier via a one-way clutch; a hybrid power mode in which the engine and motor jointly transmit power to the planetary gear set, etc. Multiple modes can meet the needs of the vehicle under different driving conditions, such as starting, low-speed driving, and high-speed driving, ensuring both power performance and improved fuel economy.

[0039] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures.
