[0031] Reference Figures 1 to 4 According to the engine crankcase cover oil filter circuit of the first embodiment of the utility model, the engine crankcase cover oil filter circuit includes: a cover and a filter. The cover is provided with a plurality of interconnected oil passages, the oil passages are connected to the oil pump and various oil passages, and a filter chamber is provided on the outside of the cover; the filter is provided in the filter chamber, the filter is connected to the oil passage, the oil passage includes an oil inlet passage, one end of the oil inlet passage is connected to the oil pump, and the other end of the oil inlet passage is connected to the filter chamber, the oil passage also includes an oil outlet passage, one end of the oil outlet passage is connected to the filter chamber, and the other end of the oil outlet passage is connected to various oil passages.
[0032] Specifically, the engine crankcase cover oil filter circuit mainly includes two parts: the cover and the filter. Several interconnected oil passages are arranged inside the cover, which are not only connected to the oil pump, but also to the oil passages of each level of the engine. In particular, a filter chamber is arranged on the outside of the cover for installing the filter. The oil passages inside the cover are crisscrossed to form a network, ensuring that the oil can flow smoothly from the oil pump to the oil passages of each level. Among them, the two important oil passages are the oil inlet passage and the oil outlet passage. One end of the oil inlet passage is connected to the oil pump, and the other end is connected to the filter chamber, ensuring that the oil pumped out from the oil pump can first flow through the filter for filtration. One end of the oil outlet passage is connected to the filter chamber, and the other end is connected to the oil passages of each level, so that the filtered clean oil can flow smoothly to various parts of the engine that need lubrication.
[0033] It should be noted that the filter chamber is located on the outside of the case cover, and its size and shape are determined according to the specifications and design of the filter. The filter is arranged in the filter chamber and is connected to the oil passage. The specific structure and filtering principle of the filter will be described in detail below. When the engine is running, the oil pump pumps the oil into the oil inlet passage, and the oil then flows into the filter in the filter chamber. The filter effectively removes impurities and particulate matter in the oil, ensuring that only clean oil can pass through. The filtered clean oil then flows to the various oil passages of the engine through the oil outlet passage, providing the necessary lubrication and cooling for the engine. By integrating the oil filtering function on the crankcase cover, the structure of the engine is simplified, and the filtering effect of the oil is improved. It not only facilitates the installation and removal of the filter, but also helps to maintain the cleanliness of the oil, thereby improving the operating efficiency of the engine and extending its service life.
[0034] The engine crankcase cover oil filter circuit according to the embodiment of the utility model has at least the following beneficial effects: the oil pump pumps the oil to the oil channel in the cover, and then enters the filter in the filter chamber after passing through the oil inlet channel; after being filtered by the filter, it can flow out from the oil outlet channel and be sent to the oil channels at all levels. The filter is arranged on the outside of the crankcase, which can facilitate the disassembly, maintenance and cleaning of the filter on the one hand, and is also conducive to the heat dissipation of the oil in the filter, thereby ensuring the good performance of the oil.
[0035] Reference Figures 1 to 4 In some embodiments of the present invention, the filter includes a main body, a filter element and a filter cover. The main body is arranged on the outside of the box cover, the main body and the box cover are integrally formed, and the interior of the main body forms a filter cavity; the filter element is arranged in the filter cavity; the filter cover is detachably arranged at the outer end of the main body, and the inner side of the filter cover abuts against the filter element.
[0036] Specifically, the main body of the filter is arranged on the outside of the box cover and is integrally formed with the box cover, which not only enhances the stability of the structure but also helps to simplify the manufacturing process. A specific filter cavity is formed inside the main body, which is the main place for oil filtering. A filter element is arranged in the filter cavity. The filter element is the core component of oil filtration, which can effectively intercept impurities and particles in the oil to ensure that only clean oil can pass through. The material and structure of the filter element can be selected to provide the best filtering effect. In order to protect the filter element and facilitate maintenance, the filter is also equipped with a detachable filter cover. This filter cover is arranged at the outer end of the main body and can be easily removed and installed. The inner side of the filter cover is tightly abutted against the filter element, which not only ensures the stability and sealing of the filter element, but also provides convenience when the filter element needs to be replaced. When the oil flows through the filter cavity, the filter element intercepts and absorbs impurities and particles in the oil to ensure that the oil flowing to the engine is clean. After the filter element has been used for a period of time, the filter element can be easily replaced by removing the filter cover, thereby maintaining the continuous effectiveness of the oil filtration system. It not only improves the cleanliness of the engine oil, but also helps to extend the service life of the engine and improve its operating efficiency. At the same time, due to the detachable design of the filter cover, maintenance becomes simpler and more convenient.
[0037] Further, refer to Figures 1 to 4 In some embodiments of the utility model, a radially extending engine oil passage is provided at the bottom of the filter cavity, the bottom end of the filter element abuts against the outside of the engine oil passage, a filter oil passage is provided at the axis of the filter element, and the oil passage opening of the filter oil passage is sleeved on the engine oil passage and communicated with the engine oil passage.
[0038] Specifically, a radially extending oil passage is designed at the bottom of the filter cavity. This oil passage not only provides a flow channel for the oil, but also plays a role in supporting and positioning the filter element. The bottom end of the filter element is tightly abutted against the outside of the oil passage, ensuring the stability of the filter element during the filtering process and preventing it from shifting due to the flow of oil; it also improves the uniformity of the oil passing through the filter element, thereby improving the filtering effect. A filter oil passage is provided at the axial part of the filter element. This filter oil passage is tightly combined with the filter material outside the filter element. When the oil flows from the outside of the filter element, impurities and particulate matter are intercepted, and clean oil enters the filter oil passage of the axis through the filter material. The passage opening of the filter oil passage can be sleeved on the oil passage and maintain close communication with the oil passage, ensuring that the clean oil filtered by the filter element can flow smoothly into the oil passage and then flow to various parts of the engine. In order to ensure the tightness and sealing of the sleeve, a seal or sealing structure may be further provided at the connection between the filter oil passage and the oil passage.
[0039] When the engine oil flows from the oil pump into the filter chamber, the oil first contacts the outside of the filter element. Under the interception of the filter element, the impurities and particles in the oil are retained outside the filter element, while the clean oil passes through the filter element into the filter oil passage of the axis. Subsequently, the clean oil flows from the filter oil passage into the oil passage, and then flows to various parts of the engine that need lubrication through the oil outlet passage.
[0040] Further, refer to Figures 1 to 4 In some embodiments of the utility model, the engine oil channel is protruded from the bottom of the filter cavity, a connecting protrusion is provided on the outer side of the engine oil channel, the axis of the filter element is sleeved on the connecting protrusion, the filter oil channel is connected with the engine oil channel through the connecting protrusion, and a sealing ring is sleeved on the connecting protrusion.
[0041] The oil passage is convexly arranged at the bottom of the filter cavity. This convex design not only enhances the structural strength of the oil passage, but also facilitates the smooth flow of the oil. At the same time, the convex oil passage provides a stable installation foundation for the connecting protrusion. A connecting protrusion is arranged on the outside of the oil passage, which not only plays the role of positioning the filter element, but also ensures the tight connection between the filter element and the oil passage. The axial part of the filter element can be sleeved on this connecting protrusion, thereby realizing the stable connection between the filter element and the oil passage. Through the connecting protrusion, the filter oil passage and the oil passage are closely connected. When the filter element is sleeved on the connecting protrusion, the opening of the filter oil passage is aligned with the oil passage, ensuring that the clean oil filtered by the filter element can flow smoothly into the oil passage. In order to further improve the sealing of the connection and prevent oil leakage, a sealing ring is also sleeved on the connecting protrusion. The sealing ring fits tightly between the connecting protrusion and the filter element, effectively preventing the oil from leaking from the connection.
[0042] When the oil flows from the oil pump into the filter chamber, it is first filtered through the filter element. The clean oil then enters the filter oil passage at the center of the filter element and flows into the oil passage through the connecting protrusion. The sealing ring ensures the sealing during this process and prevents the leakage of the oil. It not only improves the reliability and stability of the oil filtration system, but also ensures the cleanliness and smooth flow of the oil. At the same time, the use of the sealing ring further enhances the sealing of the system, providing a continuous and stable supply of clean oil to the engine.
[0043] In some embodiments of the utility model, an elastic member is provided on the inner side of the filter cover, and one end of the elastic member can abut against the outer end of the filter element. An elastic member is provided on the inner side of the filter cover. This elastic member can be made of a spring, a rubber pad or other elastic material. One end of the elastic member can abut against the outer end of the filter element. It ensures that the filter element can fit tightly against the inner wall of the filter cavity when the filter cover is pressed, thereby preventing the oil from passing directly without being filtered; when the filter element is compressed or deformed due to long-term use, the elastic member can provide appropriate pressure to ensure that the filter element always maintains a tight filtering state. By providing the elastic member, not only the stability and sealing of the oil filtration system are improved, but also the filtering effect of the filter element during the entire use process is ensured. This design is conducive to extending the service life of the filter element, while maintaining the cleanliness of the oil, providing a continuous and stable supply of clean oil to the engine.
[0044] In some embodiments of the utility model, the filter cover is connected to the main body by connecting screws, and a sealing gasket is provided between the ends of the filter cover and the main body. The filter cover is firmly connected to the main body by connecting screws. This connection method is simple and easy, and can provide sufficient connection strength. The connecting screws can be evenly distributed around the periphery of the filter cover to ensure a tight fit between the filter cover and the main body. A sealing gasket is provided between the ends of the filter cover and the main body. This sealing gasket can be made of rubber, silicone or other materials with good elasticity to ensure its sealing performance. The shape of the sealing gasket matches the contact surface of the filter cover and the main body, so that an effective sealing barrier can be formed between the two.
[0045] According to the engine of the second embodiment of the utility model, the engine includes the engine crankcase cover oil filter circuit of any one of the embodiments of the first aspect. The engine provided by the utility model has the above engine crankcase cover oil filter circuit, and by arranging an external oil filter on the outside of the right crankcase cover, the filtering area is effectively increased to meet the demand for full oil filtering, so that the filtering effect is good and lasting, the use cost is low, and the maintenance is convenient and reliable. At the same time, the housing of the filter is exposed to the air, which can cool the oil.
[0046] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
