Obviously, the described embodiment is only a part of the utility model embodiment, not all the embodiments. Based on the embodiment in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor belong to the scope of the utility model protection.
[0043] In the description of the utility model, it is necessary to explain that, unless there is definite stipulation and limitation, the terms "mount", "connect", "connect" should be understood broadly, for example, it can be fixed connection, also can be detachable connection, or integrally connected, can be direct connection, also can be indirectly connected through intermediate medium, can be the communication inside two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to specific circumstances.
[0044] In addition, although the terms used in the utility model are selected from the known and common terms, some terms mentioned in the utility model specification can be selected by the applicant according to his or her judgment, and the detailed meaning is described in the relevant part of the description.
[0045] In addition, the utility model is required to be understood not only by the actual terms used, but also by the meaning implied by each term.
[0046] The technical scheme provided by the embodiments of the utility model is described in detail below with reference to the drawings.
[0047] The utility model embodiment provides a kind of oil baffle assembly. Reference Figures 1 to 4 The oil baffle assembly 100 provided by the utility model embodiment includes an oil baffle body 110 and an oil collector 120.
[0048] The oil baffle body 110 is provided with a first oil passage 111, and the first oil passage 111 extends from one side of the oil baffle body 110 to the opposite side. The oil collector 120 is provided with a second oil passage 121, and the second oil passage 121 is in communication with the first oil passage 111. One end of the first oil passage 111 away from the second oil passage 121 is provided with a first oil port 1111, and the first oil port 1111 is used to connect with the oil inlet of the oil pump.
[0049] In this way, in the embodiment of the utility model, the first oil passage 111 can be opened on the oil baffle body 110, and the second oil passage 121 of the oil collector 120 is in communication with the first oil passage 111. Therefore, the oil pump can suck oil from the oil pan through the second oil passage 121 and the first oil passage 111, so as to supply oil to the lubrication site.
[0050] In this way, the arrangement difficulty of the oil pipe can be reduced by using the first oil passage 111 opened in the oil baffle body 110 to replace at least part of the oil pipe, and the procurement cost of the oil pipe can be reduced.
[0051] In some embodiments, the first oil passage 111 is also provided with a second oil port 1112. Reference Figure 2The second oil port 1112 is arranged at a lower position of the oil baffle body 110. The second oil passage 121 is provided with a third oil port 1211. Referring to Figure 2 The third oil port 1211 is arranged at a top end of the oil collector 120. The third oil port 1211 is in butt joint with the second oil port 1112. In this way, the second oil passage 121 and the first oil passage 111 are connected in communication through the butt joint of the third oil port 1211 and the second oil port 1112.
[0052] In some embodiments, the first oil passage 111 extends in a straight line. In this way, the structure of the first oil passage 111 can be simplified, thereby reducing the difficulty of opening the first oil passage 111 and lowering the manufacturing cost of the oil baffle body 110.
[0053] Referring to Figure 3 In some embodiments, the cross-sectional area of the first oil passage 111 gradually decreases in a direction from the first oil port 1111 towards the second oil port 1112.
[0054] It should be noted that the oil baffle body 110 can be made by injection molding, and the first oil passage 111 can be formed on the oil baffle body 110. For example, during the injection molding of the oil baffle body 110, a mold can be inserted into the first oil passage 111. Then, after the plastic part is formed, the mold inserted into the first oil passage 111 can be removed to form the first oil passage 111 on the oil baffle body 110.
[0055] To facilitate the removal of the mold inserted into the first oil passage 111 during the manufacturing of the oil baffle body 110, the mold inserted into the first oil passage 111 needs to have a certain draft angle. In this way, due to the draft angle of the mold, the cross-sectional area of the first oil passage 111 gradually decreases.
[0056] Specifically, in combination with Figure 1 and Figure 3 In a direction from left to right, the cross-sectional area of the first oil passage 111 gradually decreases. In addition, the mold inserted into the first oil passage 111 is in a circular truncated cone structure, and thus the first oil passage 111 is a tapered hole with a thick left side and a thin right side.
[0057] In addition, in some embodiments, the oil collector 120 can also be made by injection molding. The second oil passage 121 can be opened on the oil collector 120 in a similar way to the opening of the first oil passage 111 on the oil baffle body 110.
[0058] In some embodiments, the second oil port 1112 penetrates the circumferential sidewall of the first oil passage 111. Illustratively, in combination with Figure 2 and Figure 3 , the second oil port 1112 penetrates the circumferential sidewall of the first oil passage 111 in a vertical direction. In this way, the second oil port 1112 can be docked with the third oil port 1211 of the top of the oil collector 120.
[0059] Referring to Figure 2 and Figure 3 , in some embodiments, the end of the second oil passage 121 away from the oil baffle plate body 110 is provided with a fourth oil port 1212, and the cross-sectional area of the end of the second oil passage 121 toward the first oil passage 111 gradually increases in the direction from the fourth oil port 1212 toward the third oil port 1211.
[0060] Illustratively, the cross-sectional area of the second oil port 1112 is substantially equal to the cross-sectional area of the third oil port 1211, so that the second oil port 1112 can be smoothly docked with the third oil port 1211. The cross-sectional area of the third oil port 1211 is 1.5 to 5 times the cross-sectional area of the fourth oil port 1212. In this way, the phenomenon of poor oil delivery due to the small cross-sectional area of the third oil port 1211 of the second oil passage 121 can be avoided.
[0061] Referring to Figure 1 and Figure 2 , in some embodiments, the oil baffle plate assembly 100 further comprises a filter 130. The filter 130 is arranged between the second oil port 1112 and the third oil port 1211. In this way, the filter 130 arranged between the second oil port 1112 and the third oil port 1211 can filter the oil flowing through the second oil passage 121 and the first oil passage 111, so as to improve the cleanliness of the oil.
[0062] It should be noted that in other embodiments, the filter 130 can not be arranged between the second oil port 1112 and the third oil port 1211. For example, a filter can be arranged on the outlet pipeline of the oil pump. In this way, the disassembly convenience of the filter can be improved.
[0063] Of course, in the case where the filter 130 is arranged between the second oil port 1112 and the third oil port 1211, the filter 130 can be a coarse filter for filtering large particles such as iron filings, so as to reduce the risk of clogging of the filter 130. In addition, for example, the filter 130 can be flushed by the oil in the first oil passage 111 by controlling the oil pump to periodically reverse, so as to reduce the risk of clogging of the filter 130.
[0064] Referring to Figure 1 and Figure 2In some embodiments, the oil baffle assembly 100 further comprises a sealing ring 140. The sealing ring 140 is arranged at the outer periphery of the portion of the oil baffle body 110 where the first oil port 1111 is arranged. The first oil port 1111 is configured to be sealingly connected with an oil inlet of the oil pump via the sealing ring 140. For example, the oil inlet of the oil pump can be sleeved on the first oil port 1111 so as to be sealingly connected with the oil inlet via the sealing ring 140.
[0065] In this way, the oil pump can be connected with the first oil port 1111 of the first oil passage 111 of the oil baffle body 110 in a sealing manner, so that the oil pump can suck oil from the oil pan through the first oil passage 111 of the oil baffle body 110 and the second oil passage 121 of the oil collector 120, and supply the oil to the lubrication position as needed.
[0066] In some embodiments, the oil baffle body 110 and the oil collector 120 are both plastic parts, and the two can be welded by a vibration friction welding process so as to be connected as one. Of course, in the case where the oil baffle assembly 100 comprises the filter 130, the filter 130 can be arranged between the second oil port 1112 and the third oil port 1211 before the oil baffle body 110 and the oil collector 120 are welded. Thus, after the welding is completed, the filter 130 will be clamped between the second oil port 1112 and the third oil port 1211.
[0067] In addition, the oil baffle body 110 and the oil collector 120 can also be connected by means of glue bonding and the like.
[0068] It should be noted that in other embodiments, the oil baffle body 110 and the oil collector 120 can also be made of other materials. For example, the oil baffle body 110 and the oil collector 120 can be made of metal, and the oil baffle body 110 and the oil collector 120 can be connected by a metal welding process.
[0069] The materials and connection processes of the oil baffle body 110 and the oil collector 120 can be flexibly selected according to requirements, which will not be listed one by one here.
[0070] In some embodiments, the filter 130 comprises an outer frame and a filter screen. The outer frame is arranged around the outer periphery of the filter screen so as to keep the filter screen in a predetermined shape. In addition, the outer frame can be clamped between the hole edge of the second oil port 1112 and the hole edge of the third oil port 1211. It should be noted that the material of the filter screen can be flexibly selected according to actual requirements, which will not be listed one by one here.
[0071] Reference Figure 1 and Figure 2In some embodiments, the oil baffle assembly 100 further comprises a plurality of metal bushings 150. The oil baffle body 110 is provided with a plurality of through holes. The metal bushings 150 can be provided in the through holes one by one. For example, the metal bushings 150 can be provided in the through holes by an interference press-fit process. For example, the metal bushing 150 is provided with a mounting hole, and the oil baffle body 110 can be mounted on the cylinder block of the engine through a bolt passing through the mounting hole of the metal bushing 150. For example, the engine cylinder block is provided with a threaded hole matched with the bolt, and the bolt passing through the mounting hole of the metal bushing 150 can be fixed on the engine cylinder block by screwing into the threaded hole. By using the scheme provided in this embodiment, the connection firmness between the oil baffle assembly 100 and the cylinder block of the engine can be improved by embedding the metal bushing 150.
[0072] For example, the metal bushing 150 can be a steel sleeve. The metal bushing 150 is provided with a mounting hole for the bolt to pass through. It should be noted that those skilled in the art can flexibly set the material of the metal bushing 150 according to actual needs during implementation of the embodiments of the utility model, and thus the specific material of the metal bushing 150 will not be listed one by one here.
[0073] In some embodiments, the sealing ring 140 is an O-shaped sealing ring. The sealing ring 140 can be connected with the oil pump by being inserted into the oil inlet of the oil pump at the part of the oil baffle body 110 where the first oil port 1111 is located.
[0074] For example, the oil baffle body 110 is provided with a protruding ring at the part where the first oil port 1111 is located. The inner wall of the protruding ring forms the first oil port 1111. Referring to Figure 2 , the protruding ring protrudes to the left. The outer peripheral wall of the protruding ring is provided with an annular groove, and the sealing ring 140 is clamped in the annular groove of the protruding ring. Further, the protruding ring can be inserted into the oil inlet of the oil pump, so that the sealing ring 140 is in sealing cooperation with the groove wall of the annular groove and the side wall of the oil inlet, respectively. In this way, the sealing effect of the oil inlet of the oil pump and the first oil port 1111 of the oil baffle body 110 can be improved by providing the sealing ring 140.
[0075] For example, the O-shaped sealing ring can be a butyronitrile rubber sealing ring or a fluorine rubber sealing ring, etc. Of course, the O-shaped sealing ring can also be made of other oil-resistant materials, and those skilled in the art can flexibly set the material of the O-shaped sealing ring according to actual needs during implementation of the embodiments of the utility model, and thus the specific material of the O-shaped sealing ring will not be listed one by one here.
[0076] The utility model embodiment provides a kind of engine.The utility model embodiment provides the engine comprising: the utility model embodiment provides any one oil baffle assembly 100.Exemplarily, engine can be diesel engine or gasoline engine or the engine of other types.
[0077] Reference Figure 4 In some embodiments, the engine further comprises: cylinder body and oil pan 200.Oil pan 200 cover is located in the lower side of cylinder body, and oil baffle assembly 100 is located in the area surrounded by oil pan 200 and cylinder body.The side of oil pan 200 deviating from the front end of engine is provided with lower recess 210, and one end of second oil passage 121 extends into the area surrounded by lower recess 210.
[0078] In this way, during the climbing process of the vehicle provided with the engine, oil can be collected to the lower recess 210 at the rear side under the action of gravity.So that the lower end of the second oil passage 121 of the oil collector 120 can always be below the oil level, so that the phenomenon that the oil pump cannot suck oil can be avoided.
[0079] In addition, it should be noted that during the downhill process of the vehicle provided with the engine, oil can be collected to the front side of oil pan 200 under the action of gravity.In general, a small amount of oil is also retained in lower recess 210, so that the oil pump can also suck oil.Furthermore, since the vehicle can move under the action of gravity during the downhill process of the vehicle provided with the engine, the lubrication demand of the engine is small when the engine is in a low-power working state, so that the supply amount of oil can meet the lubrication demand during the downhill process of the vehicle provided with the engine.
[0080] Reference Figure 3 And Figure 4 In some embodiments, the first oil passage 111 extends from the rear side of the engine to the front side of the engine.In this way, the oil on the rear side of the oil pan can be transported to the oil pump located at the front side through the second oil passage 121 and the first oil passage 111.
[0081] It should be noted that in the engine lubrication system, the oil pump is used to suck oil from the oil pan 200, and after the oil is raised to a certain pressure, it is supplied to each lubrication site.Exemplarily, the oil pump can be a gear type oil pump, a turbine type oil pump or a plunger type oil pump or other types of hydraulic pump.Of course, those skilled in the art can also flexibly select the appropriate type of hydraulic pump according to the actual needs during the implementation of the embodiments provided by the utility model, which will not be listed one by one here.
[0082] It should be noted that in some embodiments, the engine comprises a cylinder block, an oil pan 200, a crankshaft, a piston and the oil baffle assembly 100. The cylinder block is provided with a piston hole, and the piston is slidingly arranged in the piston hole. The piston is connected to the lower crankshaft through a connecting rod. The oil pan 200 is arranged below the cylinder block, and the oil baffle assembly 100 is arranged in the area surrounded by the oil pan 200 and the cylinder block. The oil pan 200 contains engine oil, wherein the engine oil mainly plays a role of lubricating, cooling and cleaning the moving pairs.
[0083] In some special working conditions of the vehicle provided with the engine, the engine oil may surge in a large amplitude. In order to avoid the splashing of the surging engine oil to the working area of the crankshaft, and to avoid the phenomenon of the crankshaft stirring the engine oil, the oil baffle assembly 100 can be arranged above the oil pan 200, and the baffle body 110 is located above the engine oil level and below the crankshaft. In this way, the baffle body 110 can be shielded between the crankshaft and the engine oil, so as to prevent the phenomenon of the crankshaft stirring the engine oil.
[0084] Exemplarily, the side wall of the oil pan 200 surrounds the outer periphery of the baffle body 110. Therefore, the shape of the baffle body 110 can be matched with the shape of the side wall of the oil pan 200, so as to prevent the surging engine oil from bypassing the baffle body 110 and splashing to the area where the crankshaft is located.
[0085] Further, the oil baffle assembly is provided with a first oil passage 111 and a second oil passage 121 which are connected in communication. The fourth oil port 1212 at the lower end of the second oil passage 121 is submerged below the engine oil level. Therefore, in the case that the engine oil pump is working in connection with the first oil port 1111 of the first oil passage 111, the engine oil pump can suck the engine oil from the oil pan 200 through the second oil passage 121 and the first oil passage 111. Further, the engine oil sucked by the engine oil pump can be delivered to each lubrication site through an oil delivery pipeline, wherein the lubrication site is respectively located in the piston, the crank, the connecting rod, etc.
[0086] Further, the side of the oil pan 200 close to the rear end of the engine is provided with a lower recess 210, and the fourth oil port 1212 at the lower end of the second oil passage 121 extends into the area surrounded by the lower recess 210. In this way, in the case that the vehicle provided with the engine is in a high-power working condition such as climbing a steep slope, the engine oil in the oil pan 200 can be collected to the lower recess 210 under the action of gravity. In this way, the fourth oil port 1212 at the lower end of the second oil passage 121 can always be submerged below the engine oil level. In this way, it can be ensured that the engine oil pump can always suck the engine oil from the oil pan 200, so that the engine oil can be continuously supplied to each lubrication site.
[0087] Further, the oil seeping from each lubrication site can flow downward under the action of gravity. Furthermore, the oil seeping from each lubrication site can pass through the gap between the oil baffle body 110 and the oil pan 200 and be collected at the bottom of the oil pan. In this way, the oil can be recycled.
[0088] In some embodiments, the oil baffle body 110 and the oil collector 120 are respectively provided with reinforcing ribs to improve their own structural strength. An oil passing gap is provided between the outer periphery of the oil baffle body 110 and the inner wall of the oil pan 200. In this way, the returned oil can pass through the oil passing gap and be collected at the bottom of the oil pan. The top surface of the oil baffle body 110 is provided with a recessed avoidance portion opposite the crankshaft, so as to prevent the crankshaft from interfering with the oil baffle body 110.
[0089] In some embodiments, the oil baffle body 110 extends in a direction from the front end of the engine toward the rear end of the engine. The first oil passage 111 also extends in a direction from the front end of the engine toward the rear end of the engine. The second oil passage 121 is connected to the side of the first oil passage 111 close to the rear end of the engine. The first oil port 1111 at the front end of the first oil passage 111 is connected to the oil inlet of the oil pump. In this way, for some special engine models, when it is difficult to leave a space for arranging the oil pump at the rear end of the engine, the oil pump can be conveniently arranged at the front end of the engine.
[0090] The utility model embodiment provides a kind of vehicle. The vehicle provided by the utility model embodiment includes any one of the engine provided by the utility model embodiment. Exemplarily, the vehicle can be Off-Road Vehicle (abbreviated as ORV). The vehicle can be sport utility vehicle (abbreviated as SUV). The vehicle can be a small car. Here is not listed one by one.
[0091] To facilitate the skilled in the art to apply the scheme provided by the utility model embodiment, the following, briefly introduce the beneficial effects generated by the scheme provided by the utility model embodiment.
[0092] In the embodiment of the utility model, the oil baffle body 110 and the oil collector 120 are connected as a whole, the first oil passage 111 of the oil baffle body 110 is communicated with the second oil passage 121 of the oil collector 120, so that the oil baffle assembly 100 forms an integrated oil suction passage. Thus, the oil pump can be connected with the oil collector 120 through flexible adjustment of the direction of the first oil passage 111 according to requirements, so that the oil pump sucks oil from the oil pan 200 through the integrated oil suction passage, thereby supplying oil to each lubrication site. The scheme provided by the embodiment of the utility model can replace the oil pipe with the integrated oil suction passage, thereby reducing the number of parts, reducing weight and cost.
[0093] In some embodiments, the size parameters, shape parameters and installation positions of the oil baffle body 110 can be reasonably set according to requirements, so that the oil baffle body 110 can better shield the oil between the crankshaft connecting rod mechanism and the oil pan 200 below, thereby reducing the risk of stirring oil by the crankshaft and reducing the gas content in the oil. Thus, the phenomenon that bubbles enter the moving pair with the oil, causing abnormal wear of the moving pair, and bubbles enter the oil cooler with the oil, causing cavitation of the oil cooler, can be avoided. Thus, the service life of the engine can be improved.
[0094] In some embodiments, the oil inlet of the oil collector 120 is arranged at the rear end of the engine and extends into the area surrounded by the lower recess 210 of the oil pan 200. In this way, when the vehicle equipped with the engine is in a high-power working condition such as climbing a steep slope, the oil in the oil pan 200 can be collected into the lower recess 210 under the action of gravity. Thus, the oil inlet (i.e., the fourth oil port 1212 at the lower end of the second oil passage 121) of the oil collector 120 is always submerged below the oil level. In this way, the oil pump can always suck oil from the oil pan 200, so that oil can be continuously supplied to each lubrication site. Thus, the oil suction capacity of the oil pump can be improved when the vehicle is climbing a steep slope, so that each lubrication site can be normally lubricated when the vehicle is in a large-angle climbing condition.
