Description

Technical Field

[0001] The utility model relates to the technical field of vehicles, in particular to a drive assembly and a vehicle. Background Art

[0002] In the prior art, vehicles use a dual electric drive assembly with oil cooling, and the oil collection position needs to be determined based on the assembly position, the suction filter position and the cooling and lubrication system requirements. The dual electric drive has a long axial dimension, and it is necessary to prevent the oil from flowing or rushing to the same side when the vehicle is tilting or the assembly is running, causing the suction filter to be empty.

[0003] The two commonly used technical solutions are as follows:

[0004] 1. Parallel axis T-type structure: The oil collection position is the output shaft of the reducer. The space at the output shaft is relatively narrow. According to the total oil demand, it is necessary to increase the oil volume by raising the liquid level or increasing the size of the shell around the output shaft of the reducer. This can easily lead to increased oil loss, affect the assembly efficiency, increase the assembly volume, and affect the layout and lightweight of the vehicle.

[0005] 2. Planetary gear coaxial structure:

[0006] An independent oil pan is used, in which all the oil is concentrated, and then the oil pan is fixed to the motor housing. This solution requires increasing the types of materials and the sealing structure between the oil pan and the motor housing, which increases the difficulty of assembly and the risk of oil leakage.

[0036] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figure 1-Figure 6 The drive assembly 100 according to the embodiment of the present invention is described, comprising: a housing 10, a partition plate 20, a first motor 13 and a second motor 14. The housing 10 has a first direction A and a second direction B.

[0037] Specifically, if Figure 1-Figure 3 As shown, the shell 10 defines a accommodating cavity, and a partition plate 20 is disposed in the accommodating cavity. The partition plate 20 divides the accommodating cavity into a first chamber 11 and a second chamber 12 arranged on the left and right. The upper parts of the first chamber 11 and the second chamber 12 are connected, and at least one connecting hole 21 is formed at the lower part of the partition plate 20. The connecting hole 21 connects the first chamber 11 and the second chamber 12. The first motor 13 is disposed in the first chamber 11, and the second motor 14 is disposed in the second chamber 12.

[0038] Combination Figure 1-3 The partition plate 20 extends along the second direction B of the housing 10, the first chamber 11 and the second chamber 12 are respectively arranged on both sides of the partition plate 20 along the first direction A of the housing 10, the first chamber 11 and the second chamber 12 are connected along the upper part of the housing 10 in the second direction B, and the partition plate 20 is provided with a connecting hole 21 at the lower part of the housing 10 in the first direction A to achieve the connection between the first chamber 11 and the second chamber 12 at the lower part of the second direction B. The bottom of the first chamber 11 and the second chamber 12 along the second direction B of the housing 10 both have a certain amount of oil 42, and the first motor 13 and the second motor 14 are arranged above the oil 42 along the second direction B of the housing 10, so as to provide the first motor 13 and the second motor 14 with the oil 42 for lubrication and cooling. The connecting hole 21 connects the first chamber 11 and the second chamber 12 so that the oil 42 can flow between the first chamber 11 and the second chamber 12, and balance the height difference of the oil 42 inside the first chamber 11 and the second chamber 12.

[0039] During the operation of the drive assembly 100, the temperature of the first motor 13 and the second motor 14 rises and they need to be sprayed with oil 42 to achieve a cooling effect. When the oil 42 is sprayed, high-temperature oil gas 43 is generated, and the oil gas 43 flows between the first chamber 11 and the second chamber 12 at the top of the partition plate 20. The drive assembly 100 is suitable for installation on a vehicle. When the vehicle bumps during driving, the drive assembly 100 will follow the vehicle to a certain extent, causing the oil 42 and the high-temperature oil gas 43 in the housing 10 to converge toward one of the first chamber 11 and the second chamber 12. As the use time increases, there is a height difference between the oil 42 in the first chamber 11 and the second chamber 12. The connecting hole 21 is formed on the partition plate 20 so that the oil 42 can flow between the first chamber 11 and the second chamber 12 through the connecting hole 21 to balance the oil 42 in the first chamber 11 and the second chamber 12.

[0040] According to the drive assembly 100 of the embodiment of the utility model, a connecting hole 21 is set on the partition plate 20 in the shell 10 of the drive assembly 100 to connect the first chamber 11 and the second chamber 12, so that the oil 42 can flow between the first chamber 11 and the second chamber 12. When the drive assembly 100 tilts during operation and causes a large amount of oil 42 to flow into a certain chamber, the oil 42 can flow back through the connecting hole 21 to keep the oil 42 in the first chamber 11 and the second chamber 12 balanced, thereby avoiding the phenomenon that too much oil 42 in a certain chamber floods the rotor air gap of the motor and affects the motor efficiency, and insufficient oil 42 in another chamber causes poor lubrication of the motor and other components, thereby improving the reliability and working efficiency of the drive assembly 100 and reducing the sealing cost.

[0041] According to some embodiments of the present invention, Figure 1-3 As shown, both the first chamber 11 and the second chamber 12 contain oil 42. When the housing 10 is horizontal and the liquid levels in the first chamber 11 and the second chamber 12 are flush, the lowest point of the communication hole 21 is located below the liquid level.

[0042] That is, when the housing 10 is in a horizontal position, at least a portion of the connecting hole 21 is located below the surface of the oil 42 in the first chamber 11 and the second chamber 12, ensuring that the oil 42 can communicate between the first chamber 11 and the second chamber 12 through the connecting hole 21. The drive assembly 100 is prone to shaking or tilting during operation, causing the oil 42 in the first chamber 11 and the second chamber 12 to splash into the other side chamber, resulting in excessive oil 42 in one side chamber. The lowest point of the connecting hole 21 is located below the liquid level when it is flush, which can ensure that the liquid level in the chamber with more oil 42 is higher than the connecting hole 21, so that the oil 42 in the chamber with more oil 42 can flow through the connecting hole 21 to the chamber with less oil 42.

[0043] Therefore, when the liquid levels of the first chamber 11 and the second chamber 12 are flush, the lowest point of the connecting hole 21 is located below the liquid level to ensure that when the oil 42 contents in the first chamber 11 and the second chamber 12 are different, the oil 42 can flow through the connecting hole 21 to the chamber with less oil 42 content, so as to ensure that the oil 42 in the first chamber 11 and the second chamber 12 remains balanced, thereby ensuring the working stability of the drive assembly 100.

[0044] According to some embodiments of the present invention, Figure 1-3 As shown, the diameter of the connecting hole 21 is D, and D satisfies: 1mm≤D≤5mm. If the diameter of the connecting hole 21 is greater than 5mm, the diameter of the connecting hole 21 is too large, which may easily cause the oil 42 to pass through the connecting hole 21 too quickly, causing the oil 42 to directly tilt into a certain side chamber in large quantities. Excessive oil 42 may affect the efficiency of the motor in the side chamber. If the diameter of the connecting hole 21 is less than 1mm, the diameter of the connecting hole 21 is too small, which may easily cause the oil 42 to be unable to flow back through the connecting hole 21 in time, affecting the lubrication of the motor in the chamber with less oil 42, and may easily cause blockage and lead to balance failure. For example, D=3mm.

[0045] Thus, the diameter of the connecting hole 21 is limited, so that the connecting hole 21 plays a certain damping role when balancing the oil 42 in the first chamber 11 and the second chamber 12, so that the running oil 42 can slowly flow back, and avoid the oil 42 quickly passing through the connecting hole 21 and tilting to one side again, thereby ensuring the working efficiency of the motor and improving the reliability of the drive assembly 100.

[0046] According to some embodiments of the present invention, Figure 1-3 As shown, a suction filter 30 is disposed in each of the first chamber 11 and the second chamber 12 . The suction filter 30 includes a suction filter body 33 . An inlet 34 is formed on the suction filter body 33 . The inlet 34 is located on one side of the suction filter body 33 adjacent to the partition plate 20 .

[0047] The suction filter 30 is arranged below the motor along the second direction B of the housing 10. When the housing 10 is horizontal and the liquid levels in the first chamber 11 and the second chamber 12 are flush, the suction filter 30 is immersed in the oil 42. The suction filter 30 is suitable for absorbing the oil 42 to provide lubrication and cooling for components such as the motor and the reducer. An inlet 34 is formed on the suction filter body 33 to facilitate the suction of the oil 42 by the suction filter body 33. The inlet 34 is located on one side of the suction filter body 33 adjacent to the partition plate 20 along the first direction A of the housing 10.

[0048] Therefore, the inlet 34 is located on the side of the suction filter body 33 adjacent to the partition plate 20, that is, when the drive assembly 100 is in a tilted state, the inlet 34 can always be in contact with the oil 42, effectively avoiding the suction filter 30 from being sucked empty, improving the reliability of the drive assembly 100, and extending the service life of the drive assembly 100.

[0049] According to some embodiments of the present invention, Figure 1-3 As shown, the inlet 34 is disposed at the bottom of the suction filter body 33 .

[0050] The inlet 34 is disposed below the suction filter body 33 along the second direction B of the housing 10, and the inlet 34 is adapted to be opposite to the oil 42, so that the inlet 34 can absorb the oil 42. Therefore, the inlet 34 is disposed at the bottom of the suction filter body 33 to ensure that the inlet 34 is always in contact with the oil 42, thereby avoiding the suction filter 30 from sucking empty air, and ensuring the stability and reliability of the drive assembly 100.

[0051] According to some embodiments of the present invention, Figure 5 and Figure 6 As shown, the suction filter 30 includes: a first suction filter 31 and a second suction filter 32. The first suction filter 31 is arranged in the first chamber 11, and a first mounting protrusion 311 is provided on the first suction filter 31. The second suction filter 32 is arranged in the second chamber 12, and a second mounting protrusion 321 is provided on the second suction filter 32. The position of the first mounting protrusion 311 on the first suction filter 31 and the position of the second mounting protrusion 321 on the second suction filter 32 are staggered.

[0052] The first mounting protrusion 311 is provided on a side surface of the first suction filter 31 along the first direction A of the housing 10. The first mounting protrusion 311 protrudes from a side surface of the first suction filter 31 along the first direction A of the housing 10 adjacent to the partition plate 20 and extends toward the side where the partition plate 20 is located. The first mounting protrusion 311 and the second mounting protrusion 321 are provided on a side surface of the second suction filter 32 along the first direction A of the housing 10. The second mounting protrusion 321 protrudes from a side surface of the second suction filter 32 along the first direction A of the housing 10 adjacent to the partition plate 20 and extends toward the side where the partition plate 20 is located. The first mounting protrusion 311 and the second mounting protrusion 321 are staggered on the suction filter 30 with a local height difference or completely staggered.

[0053] Therefore, the setting of the first mounting protrusion 311 facilitates the fixed installation of the first suction filter 31 in the first chamber 11, and the setting of the second mounting protrusion 321 facilitates the fixed installation of the second suction filter 32 in the second chamber 12. The position of the first mounting protrusion 311 on the first suction filter 31 and the position of the second mounting protrusion 321 on the second suction filter 32 are staggered, which can avoid the first suction filter 31 and the second suction filter 32 from being installed reversely, reducing the difficulty of assembling the first suction filter 31 and the second suction filter 32, and except for the shell 10 related to the mounting structure, the first suction filter 31 and the second suction filter 32 can share other related structures, which is beneficial to reducing the production cost of the drive assembly 100, optimizing the internal structure of the drive assembly 100, and improving the reliability of the drive assembly 100.

[0054] According to some embodiments of the present invention, Figure 1-3 As shown, a communication port 22 is formed at the upper end of the partition plate 20 , and the first chamber 11 and the second chamber 12 are communicated with each other through the communication port 22 .

[0055] The communication port 22 is located at the upper end of the partition plate 20 along the second direction B of the housing 10, and the communication port 22 penetrates the partition plate 20 along the first direction A of the housing 10, and the first chamber 11 and the second chamber 12 are connected along the upper end of the first direction A of the housing 10. Therefore, during the operation of the drive assembly 100, a certain amount of oil and gas 43 will be formed in the first chamber 11 and the second chamber 12, and the setting of the communication port 22 facilitates the formed oil and gas 43 to flow between the first chamber 11 and the second chamber 12, preventing a large amount of oil and gas 43 from accumulating in the chamber on one side, facilitating the oil and gas 43 in the first chamber 11 and the oil and gas 43 in the second chamber 12 to maintain a balance, thereby ensuring the normal operation of the drive assembly 100.

[0056] According to some embodiments of the present invention, Figure 1-3 As shown, it also includes: an oil pipeline 40, which is arranged on the partition plate 20, and the oil pipeline 40 is located above the first motor 13 and the second motor 14.

[0057] The oil pipe 40 is suitable for transporting oil 42 into the first chamber 11 and the second chamber 12. When the drive assembly 100 is in working state, the first motor 13 and the second motor 14 generate high temperature when working. The oil pipe 40 can spray the oil 42 onto the surface of the first motor 13 and the second motor 14 to cool the first motor 13 and the second motor 14, so that the temperature of the first motor 13 and the second motor 14 is maintained within a reasonable range.

[0058] Therefore, the setting of the oil pipe 40 is suitable for conveying oil 42 into the first chamber 11 and the second chamber 12 to cool the high-temperature first motor 13 and the second motor 14, ensuring that the first motor 13 and the second motor 14 can work normally, improving the working efficiency of the first motor 13 and the second motor 14, extending the service life of the first motor 13 and the second motor 14, and thereby extending the overall service life of the drive assembly 100.

[0059] According to some embodiments of the present invention, Figure 4 As shown, it also includes: a high-voltage connector 41, which is arranged on the partition plate 20, and the high-voltage connector 41 is electrically connected to the first motor 13 and the second motor 14.

[0060] The high-voltage connector 41 includes a first part and a second part, wherein the first part extends along a first direction A of the housing 10 and is disposed above the partition plate 20 and is perpendicular to the partition plate 20, and the second part extends along a second direction B of the housing 10 and is disposed on the partition plate 20, and is distributed in a T-shaped structure. The high-voltage connector 41 is suitable for being electrically connected to the first motor 13 and the second motor 14, so that the first motor 13 and the second motor 14 are connected, so that current flows, and the predetermined function of the circuit is realized.

[0061] Therefore, the setting of the high-voltage connector 41 ensures that the first motor 13 and the second motor 14 can operate normally. The high-voltage connector 41 is arranged on the partition plate 20, which is beneficial to improving the utilization rate of the internal structure of the shell 10, improving the assembly stability of the overall structure of the drive assembly 100, optimizing the internal structure layout of the drive assembly 100, and making the overall structure of the drive assembly 100 more compact.

[0062] The vehicle according to the second aspect of the present invention comprises the drive assembly 100 according to the first aspect of the present invention.

[0063] According to the vehicle of the embodiment of the utility model, by using the drive assembly 100 described in the above embodiment, it is beneficial to reduce the production cost of the drive assembly 100, improve the reliability and stability of the drive assembly 100, simplify the overall structure of the drive assembly 100, and reduce the maintenance cost of the drive assembly 100, thereby improving the overall stability and safety of the vehicle, ensuring that the vehicle can operate stably for a long time, extending the service life of the vehicle, reducing the subsequent maintenance cost of the vehicle, extending the service life of the vehicle, and improving the user experience.

[0064] According to some embodiments of the utility model, it includes: a controller and two gearboxes, the controller is electrically connected to the drive assembly 100, the two gearboxes are respectively arranged on the side of the first motor 13 and the second motor 14 of the drive assembly 100 away from each other, and the two gearboxes are connected to the corresponding first motor 13 or second motor 14 to output power.

[0065] The controller is connected to the driving assembly 100 and can convert the DC current of the vehicle battery into the AC current required by the driving assembly 100. The controller communicates with the vehicle through the communication system to control the speed and power required by the vehicle. The two gearboxes are respectively arranged along the first direction A of the housing 10 on the side away from the first motor 13 and the second motor 14. The two gearboxes are suitable for outputting power for the corresponding first motor 13 or second motor 14, and changing the speed of the vehicle according to the changes in the vehicle driving conditions and the road conditions to provide the vehicle with appropriate driving force.

[0066] Therefore, the setting of the controller and the two gearboxes can ensure the normal operation of the vehicle and realize functions such as speed change, and can improve the working stability of the vehicle. The two gearboxes are respectively arranged on the side where the first motor 13 and the second motor 14 of the drive assembly 100 are far away from each other, which is conducive to making the structural layout between the gearbox and the drive assembly 100 more reasonable, optimizing the vehicle structure, improving the space utilization of the vehicle, and facilitating the lightweight of the vehicle and improving the integration of the vehicle.
