DETAILED DESCRIPTION

[0027] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0028] In the present disclosure, unless otherwise specified, directional words such as "inside" and "outside" refer to "inside" and "outside" relative to the corresponding component's own contour. In addition, the terms "first", "second", "third", etc. used in the present disclosure are to distinguish one element from another and do not have order and importance. In addition, in the following description, when referring to the drawings, unless otherwise explained, the same figure numbers in different drawings represent the same or similar elements. The above definitions are only used to explain and illustrate the present disclosure and should not be understood as limitations on the present disclosure.

[0029] The present disclosure provides an oil management device, referring to Figure 1As shown in the figure, the oil management device includes a housing 1, a filter 2 and an oil pump 3. A heat exchange chamber 4 and a first oil storage chamber 5 are formed inside the housing 1. The heat exchange chamber 4 is used for the circulation of cooling medium and is provided with a heat exchanger 41. The filter 2 and the oil pump 3 are respectively installed on the housing 1, and the oil flows out through the heat exchanger 41, the first oil storage chamber 5, the filter 2 and the oil pump 3 in sequence.

[0030] Through the above technical solution, in the oil management device provided by the present disclosure, the housing 1 is formed with a first oil storage chamber 5, and the filter 2, the oil pump 3 and the heat exchanger 41 are integrated in the housing 1, so that the oil management device has multiple functions of collecting, filtering, pumping oil and heat exchange, and realizes the high integration of various functions of the oil management device, which can not only reduce the volume, but also help improve the assembly efficiency of the main engine factory. In addition, this is also conducive to using the oil management device as a modular part during maintenance, which is convenient for disassembly and oil management function testing.

[0031] It should be noted that the heat exchanger 41 used in the present disclosure can increase the heat exchange area by means of fins. Therefore, no matter what cooling medium is used, the heat exchange cavity 4 and the heat exchanger 41 are filled with cooling medium, and the cooling medium can fully exchange heat with the oil in the heat exchanger 41, and the heat exchange capacity is better. Among them, any suitable cooling medium can be used in the heat exchange cavity 4, and the present disclosure does not limit this. Optionally, the cooling medium in the heat exchange cavity 4 can be cooling water.

[0032] In the exemplary embodiment provided by the present disclosure, the filter 2 and the oil pump 3 can be arranged in any suitable manner, and the present disclosure is not limited thereto. Figure 1 As shown in , the filter 2 and the oil pump 3 can be arranged on the same side of the housing 1 and close to the first oil storage chamber 5, so that the oil pipeline between the first oil storage chamber 5, the filter 2 and the oil pump 3 can be shortened, saving space and making the layout of the oil pipeline more concise and clear, so that the layout of the oil pipeline in the housing 1 can be facilitated. In addition, since the filter 2 and the oil pump 3 are arranged on the same side of the housing 1, the layout position is more concentrated, so it is more convenient to install, disassemble and repair.

[0033] In the exemplary embodiment provided by the present disclosure, the filter 2 and the oil pump 3 can be arranged on the housing 1 in any suitable manner, and the present disclosure does not limit this. For example, the arrangement of the filter 2 and the oil pump 3 on the housing 1 can be implemented in the following ways:

[0034] In a first possible implementation, the housing 1 may be provided with a first mounting groove 15 , which is recessed inward from the surface of the housing 1 , and the filter 2 is embedded in the first mounting groove 15 and partially extends out of the first mounting groove 15 .

[0035] In a second possible implementation, the housing 1 may be provided with a second mounting groove 16 , which is recessed inward from the surface of the housing 1 , and the oil pump 3 is embedded in the second mounting groove 16 and partially extends out of the second mounting groove 16 .

[0036] In a third possible implementation, refer to Figure 1 As shown in , the housing 1 may be provided with a first mounting groove 15, the first mounting groove 15 is recessed inwardly from the surface of the housing 1, the filter 2 is embedded in the first mounting groove 15 and partially extends out of the first mounting groove 15, and the housing 1 may be provided with a second mounting groove 16, the second mounting groove 16 is recessed inwardly from the surface of the housing 1, the oil pump 3 is embedded in the second mounting groove 16 and partially extends out of the second mounting groove 16.

[0037] In the above three implementations, the filter 2 and the oil pump 3 can be installed and fixed by respectively embedding the filter 2 and the oil pump 3 in the installation grooves formed by the depressions on the surface of the housing 1. In addition, to facilitate the installation and disassembly of the filter 2 and the oil pump 3, parts of the filter 2 and the oil pump 3 can be respectively extended outside their respective installation grooves, so that when disassembling or repairing, the filter 2 can be opened to replace the filter element without replacing the entire filter 2, and the oil pump 3 can be taken out and replaced, which is convenient for disassembly and greatly saves labor time. Among them, in order to further reliably fix the filter 2 and the oil pump 3 to the housing 1, the filter 2 and the oil pump 3 can also be locked to the corresponding positions on the housing 1 by fasteners such as bolts.

[0038] In the exemplary embodiments provided in the present disclosure, reference is made to Figure 1 and Figure 2 As shown in , the housing 1 may be provided with a first oil inlet 11, a first oil outlet 12, a cooling medium inlet 13 and a cooling medium outlet 14, the heat exchange chamber 4 is respectively connected with the cooling medium inlet 13 and the cooling medium outlet 14, the first oil inlet 11 is connected with the heat exchanger 41, and the first oil outlet 12 is connected with the oil pump 3, so that the external oil can enter the heat exchanger 41 through the first oil inlet 11, first exchange heat with the cooling medium in the heat exchange chamber 4, and then be filtered through the filter 2 after heat exchange, and then enter the oil pump 3 and be transported to each part to be lubricated under the action of the oil pump 3. Among them, the cooling medium enters the heat exchange chamber 4 through the cooling medium inlet 13, and flows out through the cooling medium outlet 14 after heat exchange with the oil in the heat exchanger 41.

[0039] In the exemplary embodiment provided by the present disclosure, the filter 2 may have a second oil inlet and a second oil outlet (not shown in the figure), the second oil inlet is connected to the first oil storage chamber 5, and the second oil outlet is connected to the inlet of the oil pump 3, so that the oil in the first oil storage chamber 5 can be passed through the filter 2 to the oil pump 3 through the second oil inlet and the second oil outlet, and then flow out from the first oil outlet 12. The second oil inlet and the second oil outlet can be opened on the cylinder of the filter 2.

[0040] In the exemplary embodiments provided in the present disclosure, reference is made to Figure 2 As shown in the figure, the housing 1 also has a second oil storage chamber 6 and an adjusting chamber 7, and the first oil storage chamber 5, the second oil storage chamber 6 and the adjusting chamber 7 are sequentially layered and spaced apart from each other. For example, the first oil storage chamber 5, the second oil storage chamber 6 and the adjusting chamber 7 can be Figure 2 The second oil storage chamber 6 is connected with the first oil storage chamber 5, so that the amount of stored oil in the second oil storage chamber 6 can be adjusted by the setting of the adjustment chamber 7, thereby adjusting the amount of stored oil in the first oil storage chamber 5 connected with the second oil storage chamber 6. In this way, when the oil is supplied to the parts to be lubricated through the first oil storage chamber 5, the lubrication needs in different scenarios can be adapted by adjusting the oil storage amount in the first oil storage chamber 5.

[0041] Among them, the second oil storage chamber 6 and the regulating chamber 7 are separated from each other by a first partition 8, and the first partition 8 is slidably connected to the shell 1. The oil management device also includes an oil quantity adjustment mechanism 9, and the oil quantity adjustment mechanism 9 is used to drive the first partition 8 to slide in the shell 1 to adjust the volume ratio of the second oil storage chamber 6 and the regulating chamber 7. Through such a setting, when the oil management module is applied to the drive assembly, the oil quantity can be adjusted according to parameters such as oil temperature, oil pressure, speed, and power, so as to improve the lubrication effect of the gears therein and prevent the risks of reduced gear life and reduced reliability due to excessive oil temperature or insufficient oil supply under high speed or high load conditions.

[0042] Specifically, when the oil supply needs to be increased, the oil quantity regulating mechanism 9 is used to drive the first partition plate 8 to move toward the second oil storage chamber 6 to reduce the volume share of the second oil storage chamber 6 and increase the volume share of the regulating chamber 7. In this way, the oil overflowed from the second oil storage chamber 6 due to the reduction in volume share will flow to the parts to be lubricated through the first oil storage chamber 5 and various oil pipelines; and when the oil supply needs to be reduced, the oil quantity regulating mechanism 9 is used to drive the first partition plate 8 to move toward the regulating chamber 7 to increase the volume share of the second oil storage chamber 6 and reduce the volume share of the regulating chamber 7. In this way, due to the increase in volume share in the second oil storage chamber 6, part of the oil in the first oil storage chamber 5 will flow back and be collected in the second oil storage chamber 6, thereby reducing the oil supply to various parts. In order to avoid failure of the oil quantity regulating mechanism 9, it is necessary to ensure that the first partition plate 8 can always be reliably sealed with the housing 1 during the sliding process.

[0043] In the above embodiment, in order to facilitate the automatic regulation of the oil, the oil management device can be configured to also include a controller, a pressure sensor and a temperature sensor, wherein the temperature sensor is arranged at the first oil inlet 11, and the pressure sensor is arranged at the first oil outlet 12, and the controller is electrically connected to the temperature sensor, the pressure sensor and the oil quantity regulating mechanism 9 respectively. In this way, the controller can timely control the oil quantity regulating mechanism 9 to make corresponding pressure increase or pressure relief actions according to the oil temperature information of the first oil inlet 11 received by the temperature sensor and the oil pressure information of the first oil outlet 12 received by the pressure sensor, thereby adjusting the oil supply in real time.

[0044] In the exemplary embodiments provided in the present disclosure, reference is made to Figure 2 and Figure 4 As shown in , the oil management device may further include a slide rail 10, which is connected to the housing 1, and the first partition 8 is provided with a through hole, and the slide rail 10 is penetrated in the through hole and is slidably connected with the first partition 8, so that the space ratio of the second oil storage chamber 6 and the regulating chamber 7 can be adjusted by moving the first partition 8 along the length direction of the slide rail 10. In particular, in order to ensure that the first partition 8 can always adjust the amount of oil in the second oil storage chamber 6 during the sliding process, it is necessary to ensure that the second oil storage chamber 6 and the regulating chamber 7 are reliably sealed.

[0045] In the exemplary embodiments provided in the present disclosure, reference is made to Figure 2 and Figure 4 As shown in the figure, a plurality of slide rails 10 and through holes (not shown in the figure) can be respectively provided, and the plurality of slide rails 10 are arranged at intervals and correspond one to one with the plurality of through holes. Through such a setting, since the sliding connection position between the first partition 8 and the slide rails 10 is increased, the force on the first partition 8 is more balanced during the sliding process, and the movement process is smoother.

[0046] The first partition plate 8 may be constructed in any suitable manner, which is not limited in the present disclosure. Alternatively, since rubber has good wear resistance and sealing properties, the first partition plate 8 may be constructed as a rubber piston.

[0047] In the exemplary embodiments provided by the present disclosure, the oil quantity regulating mechanism 9 can be constructed in any suitable manner, and the present disclosure does not limit this. Alternatively, the oil quantity regulating mechanism 9 can be constructed as an air pump, which is connected to the regulating chamber 7, or the oil quantity regulating mechanism 9 can be constructed as an air pump and a pressure relief valve, which are respectively connected to the regulating chamber 7. When the oil quantity regulating mechanism 9 is constructed as an air pump, the air pump has both a pressure-boosting function and a pressure-relieving function, and when the oil quantity regulating mechanism 9 is constructed as an air pump and a pressure relief valve, the air pump only has a pressure-boosting function.

[0048] In the exemplary embodiments provided in the present disclosure, reference is made to Figure 2 and Figure 3 As shown in , the interior of the shell 1 may be provided with a second partition 101 and a third partition 102, the second partition 101 is sealedly connected to the shell 1 to separate the interior of the shell 1 into a first space and a second space, the third partition 102 is sealedly arranged in the first space to separate the first space into a first oil storage chamber 5 and a heat exchange chamber 4, and the first partition 8 is sealedly arranged in the second space to separate the second space into a second oil storage chamber 6 and a regulating chamber 7. Through such an arrangement, partitions can be used to independently separate each chamber with various functions to avoid the mutual flow of media between the chambers and affect the realization of the corresponding functions. In order to ensure reliable sealing between the chambers, the second partition 101 and the third partition 102 can be welded in the shell 1 by welding.

[0049] On the basis of the above technical solution, the present disclosure further provides a drive assembly, including the above oil management device. The first oil inlet 11 and the first oil outlet 12 in the oil management device can be respectively connected to the oil pipelines of each component to be lubricated, so that the oil management device can realize the circulation of oil supply to each component to be lubricated in the drive assembly, thereby lubricating these components to be lubricated. Here, the relevant contents of the oil management device have been described in detail in the above content, and to avoid repetition, the present disclosure will not repeat them here.

[0050] On the basis of the above technical solution, the present disclosure further provides a vehicle, including the above drive assembly, wherein the vehicle can be a gasoline vehicle, a pure electric vehicle or a hybrid vehicle, which can be flexibly selected according to actual conditions, and the present disclosure does not limit this.
