Description
Technical Field
[0001] The present application relates to the technical field of engine oil pans, and in particular to an engine oil pan with an integrated oil suction pipe and an engine. Background Art
[0002] The oil pan plays a crucial role in the diesel engine's lubrication system. It not only stores and recycles lubricating oil, but also serves as the starting point for the oil pump to draw oil. Enclosed beneath the engine's crankcase is the oil pan, which stores lubricating oil. An oil suction pipe is located within the oil pan to draw oil.
[0003] In the existing engine lubricating oil passage, the oil suction pipe and the oil pan are two independent components. Before installing the oil pan, it is necessary to install the oil suction pipe on the oil pan, pass the oil suction pipe through the side wall of the oil pan, and then connect the lubricating oil pump.
[0004] The oil suction pipe needs to be matched according to the position of the oil tank in the oil pan. Therefore, almost every engine model requires a newly designed oil suction pipe assembly and oil pan assembly to match, which leads to excessive supporting parts and high production costs.
[0005] In order to reduce the number of oil suction pipe components of an engine lubrication system, the present application provides an engine oil pan with an integrated oil suction pipe. Utility Model Content

These terms are only used to distinguish information of the same type from each other.

[0029] Example 1
[0030] In the engine's lubrication system, the section of the oil suction pipe is a negative pressure line. If the oil suction pipe is too long or the inner wall is too flat, the oil suction pressure of the oil suction pipe will be reduced, resulting in a decrease in the oil pressure of the lubrication system.
[0031] In existing diesel engines, the lubricating oil pump is generally arranged on the side of the crankshaft pulley. The oil suction pipe is connected to the lubricating oil pump outside the oil pan, passes through the side wall of the oil pan and is connected to the filter at the bottom of the oil pan.
[0032] As you can understand, the oil pan is die-cast from a thin metal or plastic sheet, forming the oil pan's shell. The bottom of the oil pan has a protrusion that forms an oil reservoir within the pan. The non-protruding portion of the bottom is typically fixed to the ring beam. Therefore, the placement of the ring beam varies between engine compartments of different designs. To prevent the oil pan's protrusion from blocking the ring beam, the oil pan's structure needs to be redesigned.
[0033] The oil suction pipe needs to be matched according to the position of the oil tank in the oil pan. Therefore, almost every engine model requires a newly designed oil suction pipe assembly and oil pan assembly to match, which leads to excessive supporting parts and high production costs.
[0034] In order to reduce the number of oil suction pipe components in the engine lubrication system, the present application provides an engine oil pan with an integrated oil suction pipe, such as Figure 1 As shown, it includes: an oil pan 1 arranged at the bottom of the crankcase.
[0035] The top surface of the oil pan 1 is an oil pan opening, and the bottom surface of the oil pan 1 is provided with a first oil storage tank 2 and a second oil storage tank 3 that are adjacent and connected; the depth direction of the first oil storage tank 2 and the second oil storage tank 3 is the direction from the oil pan opening toward the bottom of the oil pan;
[0036] Specifically, such as Figure 2 As shown, the bottom of the first oil storage tank 2 is connected to a side wall of the second oil storage tank 3, and a cavity is provided in the wall of the first oil storage tank 2, and the cavity forms a first oil suction pipe 21;
[0037] One end of the oil inlet of the first oil suction pipe 21 is connected to the second oil storage tank 3, and one end of the oil outlet 212 of the first oil suction pipe 21 is connected to the lubricating oil pump; the oil inlet is arranged in the area where the first oil storage tank 2 and the second oil storage tank 3 abut, and a filter mounting hole 211 is also provided on the oil inlet of the first oil suction pipe 21.
[0038] Specifically, the oil inlet is connected to a filter, and the filter is fixed in the second oil storage tank 3 .
[0039] During die-casting of the oil pan 1 in the embodiment of the present application, a first oil suction pipe 21 is simultaneously die-cast on one side of the second oil storage tank 3. The pipe wall of the first oil suction pipe 21 is formed by the tank wall of the first oil storage tank 2. The oil inlet of the first oil suction pipe 21 is on the side wall of the second oil storage tank 3, and the filter mounting hole 211 on the oil inlet is connected to the filter in the second oil storage tank 3. The first oil suction pipe 21 and the oil pan 1 in the embodiment of the present application are integrally formed, and then a filter mounting hole 211 is provided on the first oil suction pipe 21 for installing the filter, which can reduce the number of components of the oil suction pipe and reduce production costs. The present application can also shorten the length of the oil suction pipe and reduce oil suction resistance.
[0040] Example 2
[0041] Based on the first embodiment, the engine oil pan of the embodiment of the present application also has the following improvements.
[0042] like Figure 1 As shown, in the engine oil pan of the embodiment of the present application, the first oil suction pipe 21 is further provided with an oil outlet 212 ; the oil outlet 212 is provided on the side wall of the first oil storage tank 2 .
[0043] Furthermore, the oil outlet 212 is provided with a sealing groove 213 and a sealing protrusion 214, and a sealing gasket is provided in the sealing groove 213; the oil outlet 212 is connected to the lubricating oil circuit of the engine cylinder, and the lubricating oil circuit is connected to the lubricating oil pump.
[0044] In the embodiment of the present application, the oil outlet 212 is connected to the lubricating oil circuit on the engine cylinder block. In order to prevent pressure leakage at the interface position, the oil outlet 212 is sealed by a sealing groove 213, a sealing protrusion 214 and a sealing gasket.
[0045] Furthermore, an oil pan fixing ring 4 is provided around the oil pan opening, and the oil pan fixing ring 4 is provided with N fixing holes 41 , where N is an integer greater than or equal to 1.
[0046] In the embodiment of the present application, the oil pan 1 is installed below the engine block through the fixing hole 41 .
[0047] Furthermore, a heater mounting hole 31 is provided on the sidewall of the second oil reservoir 3. The heater mounting hole 31 is used to mount a lubricating oil heater 5. The heating end of the lubricating oil heater 5 is disposed within the second oil reservoir 3. When the lubricating oil temperature is too low, the lubricating oil heater 5 heats the lubricating oil.
[0048] Further, such as Figure 2 As shown, an oil drain port 32 is further provided on the bottom of the second oil storage tank 3. When the lubricating oil is replaced, the oil drain port 32 at the bottom of the second oil storage tank 3 is opened to allow the lubricating oil to flow out.
