Description

Technical Field

[0001] This specification relates to the field of new energy commercial vehicle technology, and in particular to an oil filter cooling system for use in new energy commercial vehicles and the new energy commercial vehicle itself. Background Technology

[0002] Typically, the electric motors or electric drive axles of new energy commercial vehicles are filled with a large amount of lubricating oil to ensure their normal operation. However, because the electric motors or electric drive axles may generate impurities such as metal shavings during operation, the lubricating oil usually needs to be filtered. Furthermore, because the electric motors or electric drive axles operate at high temperatures, the lubricating oil often absorbs a large amount of heat, resulting in a high lubricating oil temperature that cannot reach the optimal lubrication temperature.

[0003] In the prior art, a filter structure is usually installed in the oil pan, and a cooling structure is installed on top of the motor or electric drive bridge.

[0004] However, the lifespan of lubricating oil is usually longer than that of the filter structure. When replacing the filter structure located in the oil pan, a large amount of lubricating oil is often lost. Summary of the Invention

[0021] Preferably, the bottom of the first channel is a lubricating oil sealing hole, which is in close contact with the top surface of the oil filter;

[0022] The shape of the lubricating oil sealing hole is adapted to the top surface of the oil filter, and the size of the lubricating oil sealing hole is smaller than the size of the top surface of the oil filter, so that the top surface of the oil filter can contact the bottom surface of the heat exchange mounting assembly.

[0023] Preferably, a limiting element and / or a supporting element are provided in the first space of the integrated mounting base;

[0024] The limiting member is used to restrict the position of the oil filter and ensure that the top surface of the oil filter completely covers the lubricating oil sealing hole;

[0025] The support member is disposed at the bottom of the oil filter, and the support member and the bottom surface of the heat exchange mounting assembly clamp the oil filter in the middle, so that the top surface of the oil filter is in close contact with the lubricating oil sealing hole.

[0026] Preferably, the oil filter includes an external filter and an internal filter;

[0035] Preferably, the motor housing is provided with at least two integrated mounting bases, and the oil filter, the heat exchanger, and the heat exchange mounting assembly are each provided with at least two.

[0036] On the other hand, this specification provides a new energy commercial vehicle, which includes the oil filter cooling system for new energy commercial vehicles described in any of the above aspects.

[0037] The above-mentioned technical solutions adopted in this specification can achieve the following beneficial effects:

[0038] According to the above, the oil filter cooling system for new energy commercial vehicles includes an electric motor housing, an oil filter, a heat exchange mounting assembly, and a heat exchanger. The upper part of the electric motor housing is provided with an integrated mounting base, which contains a first space and a second space that are isolated from each other. The integrated mounting base has an oil outlet and an oil inlet. The oil outlet connects the first space to the interior of the electric motor housing, and the oil inlet connects the second space to the interior of the electric motor housing. The electric motor housing is provided with an oil pump assembly, which is used to deliver lubricating oil from inside the electric motor housing to the oil outlet.

The heat exchange mounting assembly has a first channel, a second channel, and a coolant connector assembly. The oil filter is disposed in the first space and is tightly fitted to the bottom end of the first channel. The heat exchanger has a lubricating oil inlet, a lubricating oil outlet, and a coolant inlet / outlet corresponding to the first channel, the second channel, and the coolant connector assembly, respectively. The heat exchanger is detachably connected to the heat exchange mounting assembly, and the first channel connects the first space and the lubricating oil inlet, while the second channel connects the second space and the lubricating oil outlet. Furthermore, with this design, during periodic lubricating oil changes, the adjacent, mutually isolated first and second spaces can simultaneously connect to the integrated oil suction and blowing equipment, improving oil change efficiency.

[0039] As can be seen, the oil filter and its supporting structure are all located on the upper part of the motor housing, facilitating disassembly and maintenance without causing significant loss of lubricating oil during disassembly. Furthermore, integrating the oil filter with the heat exchanger results in high integration, low cost, and a simplified structure. Moreover, the oil filter incorporates multiple magnets to attract magnetic metals; and by placing the oil filter at the top of the first space, magnetic metals, non-magnetic metals, and lubricating oil are separated. This ensures that non-magnetic metals deposit at the bottom of the first space while preventing magnetic metals from participating in the lubricating oil circulation, thus extending the oil filter's service life.

[0084] As can be seen, the oil filter 2 and its supporting structure are all located on the upper part of the motor housing 1, which facilitates disassembly and maintenance, and will not cause a large amount of lubricating oil to be lost during disassembly.

[0085] More preferably, the heat exchanger 4 is provided with a lubricating oil inlet 41, a lubricating oil outlet 42, a coolant inlet 43, and a coolant outlet 44, and the aforementioned lubricating oil inlet 41, lubricating oil outlet 42, coolant inlet 43, and coolant outlet 44 are all liquid circuit interfaces and / or liquid circuit connectors.

[0086] More preferably, the cooling system of the new energy commercial vehicle is directly connected to the heat exchange mounting assembly 3, and the heat exchanger 4 is only directly connected to the heat exchange mounting assembly 3.

[0092] More preferably, the size of the lubricating oil sealing hole is slightly smaller than the size of the top surface of the oil filter 2, so that the edge of the top surface of the oil filter 2 can contact the bottom surface of the heat exchange mounting assembly 3, thereby preventing the oil filter 2 from passing through the lubricating oil sealing hole and from being contained by the lubricating oil sealing hole.

[0093] Preferably, the first space 51 of the integrated mounting base 5 is provided with limiting elements and / or support elements.

[0094] Preferably, the limiting member is used to limit the position of the oil filter 2, ensuring that the top surface of the oil filter 2 completely covers the lubricating oil sealing hole.
