Detailed Description
The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.
It should be understood that the present invention uses the terms "front", "back", etc. to describe various information, but the information should not be limited to these terms, and these terms are only used to distinguish one type of information from another. For example, "front" information may also be referred to as "back" information, and "back" information may also be referred to as "front" information without departing from the scope of the present invention.
As shown in fig. 1 to fig. 2, an embodiment of the present invention provides a lubricating system of an engine, which is disposed on a crankcase 1, and is used for transmitting engine oil, specifically, the lubricating system includes an engine oil pump (not shown), an engine oil filter 2, an engine oil passage 3 and a pressure regulating valve 4, wherein the engine oil passage 3 is respectively communicated with the engine oil pump and the engine oil filter 2, and the pressure regulating valve 4 is disposed in the engine oil passage 3. The oil passage 3 includes a first oil passage 31 adjacent to the oil pump and a second oil passage 32 adjacent to the oil filter 2, and the pressure-regulating valve 4 is provided at the intersection of the first oil passage 31 and the second oil passage 32.
Based on the structure, the utility model creatively adjusts the setting position of the pressure regulating valve 4, so that the pressure regulating valve and the oil pump are separately arranged, the structure of the oil pump is simplified, the occupied space of the oil pump is reduced, more setting forms of the oil pump can be realized in the crankcase 1, and the miniaturization and the light weight of the engine are facilitated; furthermore, the pressure regulating valve 4 is arranged at the intersection of the oil passages, and can be used for supplementing the cone angle left by the drilled engine oil passage 3, so that the oil passages are more smoothly communicated, the generation of engine oil turbulence is reduced, the temperature of oil pressure and flow speed is ensured, and the mechanical loss is reduced; the pressure regulating valve 4 is far away from the oil filter 2, so that the pressure stabilizing section (namely the second oil path 32) is longer, the whole oil pressure is more stable before the oil enters the oil filter 2, and the damage of oil pressure fluctuation to a paper filter screen of the oil filter 2 is favorably reduced.
It should be noted that reducing the flow path of the lubricating oil from the oil pump to the pressure regulating valve 4 can effectively reduce the energy loss of the lubricating oil, and the energy loss of the lubricating oil in the pipeline of the oil outlet of the pressure regulating valve 4 is smaller as the pressure regulating valve 4 is closer, so that the pressure regulating valve 4 is arranged close to the oil pump in some embodiments of the present application to ensure the use effect of the lubricating oil.
Furthermore, in some embodiments of the present application, the oil passage 3 is disposed in an "L" shape, and compared with a conventional linear oil passage, the L-shaped oil passage 3 can effectively shorten a distance between the oil pump and the oil filter 2, thereby reducing an occupied space of the engine. Of course, the L-shaped oil passage 3 formed by adjusting the position of the oil pump also prevents the oil from impacting the corners of the passage during operation, reduces the flow rate of the oil, and affects the circulation of the oil. Therefore, in some embodiments of the present application, the pressure regulating valve 4 is disposed at a turning point of the "L" shaped oil passage 3, that is, at an inflection point of the L shaped oil passage 3, and this design can provide a certain buffer for the high-pressure lubricating oil flowing out of the oil pump, so as to reduce the impact of the high-pressure lubricating oil on the corner of the passage, and the regulated high-pressure lubricating oil continues to flow to the oil pipeline communicated with the oil filter 2 through the pressure regulating valve 4, and the provision of the pressure regulating valve 4 can reduce the flow resistance of the lubricating oil, thereby improving the pumping efficiency of the lubricating system.
Note that, when the oil passage 3 is not disposed in front of the oil pump, the length of the engine in the front-rear direction is not increased, and the size and weight of the entire engine are not increased, which is advantageous for weight reduction, so the end surface position of the oil passage 3 is not higher than the sealing surface of the oil pump. However, the method causes deeper processing depth, increases the difficulty of drilling processing, ensures that the function of the oil pump is not influenced by avoiding the plug because the upper passage of the oil pump cover is smaller than the upper passage of the box body.
Further, in order to reduce the weight and size of the engine, the crankcase 1 is formed of an upper case and a lower case, and the oil pump, the oil passage 3, the pressure regulating valve 4, and the oil filter 2 in the present application are located on the bottom surface of the crankcase 1.
