And therefore, the change of the oil liquid height of the oil pan can be better adapted.

Description

Technical Field

[0001] This utility model relates to the lubrication system of an internal combustion engine, specifically to an oil pump cover that facilitates oil suction. Background Technology

[0002] Depending on the structure of the oil pump, many oil pumps need to have their suction port located on the pump cover. The position of the suction port on the pump cover usually corresponds to the position of the oil inlet chamber of the oil pump. This structure cannot adapt well to changes in the oil level in the oil pan. For example, when going uphill, the oil in the oil pan tilts to one side, causing the suction port to not be fully immersed in the oil, which can easily lead to air suction and pressure fluctuations in the oil pump. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an oil pump cover that facilitates oil suction and can better adapt to changes in the oil level in the oil pan.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an oil pump cover that facilitates oil suction, wherein a small hole is provided on the inner side of the pump cover and a large hole is provided on the outer side of the pump cover, and the small hole and the large hole are connected by an oblique hole to form an oil suction channel.

[0005] In the above technical solution, by setting an oil suction channel consisting of large holes, oblique holes and small holes on the pump cover, it is equivalent to extending the oil suction channel on the pump cover laterally. In this way, the size of the pump cover and the position of the oil suction port can be designed according to the actual situation. For example, the position of the pump cover and the large hole can be extended to one side of the oil pan, so as to better adapt to the changes in the oil level in the oil pan.

[0006] Preferably, the oblique hole is a process hole formed from the side of the pump cover by a core-pulling method, and the outer end of the process hole is sealed by a process plug.

[0007] Furthermore, a filter assembly and a filter cover are installed on the outer side of the pump cover at the position corresponding to the large hole, and the filter cover is provided with an oil suction port.

[0008] Furthermore, the filter assembly includes a metal mesh and a rubber edging around the periphery of the metal mesh, and the filter assembly is clamped between the pump cover and the filter cover.

[0009] Furthermore, the outer side of the pump cover is provided with an annular boss at the position corresponding to the large hole, and the periphery of the filter cover is provided with multiple protrusions. After the filter cover covers the large hole of the pump cover and the filter assembly, the multiple protrusions are bent and hooked onto the annular boss, so that the filter assembly and the filter cover can be fixed on the pump cover.

[0010] The filter components and filter covers used in the above technical solutions have a simpler structure and are much easier to install compared to traditional ones.

[0011] In one embodiment, the inner side of the pump cover is also provided with a plurality of screw holes. Attached Figure Description

[0017] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0018] It should be noted in advance that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing" in this utility model should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0019] like Figures 1 to 4 As shown, an oil pump cover for easy oil suction is provided. The inner side of the pump cover 1 is provided with a small hole 2, and the outer side of the pump cover 1 is provided with a large hole 4. The small hole 2 and the large hole 4 are connected by an oblique hole 3 to form an oil suction channel. In this embodiment, the oblique hole 3 is a process hole formed by core pulling from the side of the pump cover 1. The outer end of the process hole is closed by a process plug 8. Obviously, the oblique hole 3 can also be formed by other processing methods.

[0020] like Figure 3 , 4As shown, a filter assembly 5 and a filter cover 6 are installed on the outer side of the pump cover 1 at the position corresponding to the large hole 4. The filter assembly 5 includes a metal mesh and a rubber edging around the metal mesh. The filter assembly 5 is clamped between the pump cover 1 and the filter cover 6. An annular boss is provided on the outer side of the pump cover 1 at the position corresponding to the large hole 4. An oil suction port 7 is provided on the filter cover 6. Multiple protrusions are provided around the periphery of the filter cover 6. After the filter cover 6 covers the large hole 4 and the filter assembly 5 of the pump cover 1, the multiple protrusions are bent and hooked onto the annular boss, so that the filter assembly 5 and the filter cover 6 can be fixed on the pump cover 1. Multiple screw holes are also provided on the inner side of the pump cover 1. After the inner side of the pump cover 1 is attached to the pump body, bolts are screwed into the screw holes to fix the two.

[0021] In this embodiment, by setting an oil suction channel consisting of a large hole 4, an oblique hole 3, and a small hole 2 on the pump cover 1, it is equivalent to extending the oil suction channel on the pump cover 1 laterally. This allows the size of the pump cover 1 and the position of the oil suction port 7 to be designed according to actual conditions. For example, the pump cover 1 and the position of the large hole 4 can be extended to one side of the oil pan, thereby better adapting to changes in the oil level in the oil pan. In addition, the filter assembly 5 and filter cover 6 installed at the position of the large hole 4 have a simpler structure and are much easier to install than traditional ones.

[0022] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.

[0023] To facilitate understanding by those skilled in the art of the improvements of this utility model over the prior art, some of the drawings and descriptions of this utility model have been simplified, and for clarity, some other elements have been omitted from this application. Those skilled in the art should realize that these omitted elements may also constitute the content of this utility model.
