Description

Technical Field

[0001] The present invention relates to the field of engine power output, and in particular to an engine power output device. Background Art

[0002] The power output structure of the engine generally includes a flywheel and a flywheel housing outside the flywheel. The flywheel of the engine is a large disc-shaped part installed at the rear end of the engine crankshaft. It is connected to the engine crankshaft as part of the transmission system and transfers kinetic energy to the transmission by cooperating with the clutch. The flywheel housing, which is located on the outside of the flywheel and the clutch, connects the engine and the transmission to bear the mass of the transmission and provide power transmission support.

[0003] At present, the traditional flywheel housing structure still has certain shortcomings during use: during use, the traditional flywheel housing structure may cause the oil inside the engine or transmission to leak into the flywheel housing due to aging of the internal sealing ring of the transmission and damage to the crankshaft oil seal. This part of the oil cannot be discharged and collected in a timely and effective manner, which may cause the clutch to slip, and thus affect the normal transmission of engine power. Secondly, during the use of the flywheel, some powder will be generated due to the friction between the clutch friction plate and the flywheel, and the flywheel ring gear will also generate some powder due to friction during use. These impurities cannot be effectively collected and cleaned, and thus accumulate inside the flywheel housing. In addition, in cases where the clutch is half-clutched, the clutch brake pad slips, and a large amount of heat will be generated due to friction. This part of the heat cannot be effectively discharged, which may cause safety hazards.

[0004] Therefore, it is necessary to provide a new engine power output device to solve the above technical problems. Summary of the Invention

[0005] The technical problem solved by the present invention is to provide an engine power output device which can discharge and collect leaked oil in a flywheel housing, clean powder in the flywheel housing, and quickly and effectively dissipate heat when the friction plate is severely heated.

[0006] In order to solve the above technical problems, the present invention provides an engine power output device comprising: a flywheel housing, a cleaning assembly and a collection assembly, the cleaning assembly comprising a connecting member, two connecting members being provided and fixedly connected to the left and right side walls of the flywheel housing, respectively, an end of the connecting member on one side being fixedly connected to a second cover body, an end of the second cover body being fixedly connected to an air intake pipe, a fan being mounted on the surface of the air intake pipe, an end of the air intake pipe relative to the second cover body being connected to a dust collection box, a sealing door being hingedly connected to the top surface of the dust collection box;

[0007] An oil inlet hole is provided at the bottom of the flywheel housing, and the collecting assembly includes a fixed tube, the top of the fixed tube is fixedly connected to the oil inlet hole, the bottom of the fixed tube is fixedly connected to a first cover body, the bottom of the first cover body is connected to a connecting tube, one end of the connecting tube relative to the first cover body is connected to an oil collecting tank, a side wall surface of the oil collecting tank is fixedly connected to an observation plate, a liquid level sensor is fixedly connected to a side position of the top of the oil collecting tank, a detection end of the liquid level sensor extends to the interior of the oil collecting tank, an oil drain pipe is fixedly connected to the top of the oil collecting tank on the side of the liquid level sensor, and a sealing cover is threadedly connected to the top of the oil drain pipe.

[0008] As a further solution of the present invention, one end of the flywheel housing is fixedly connected to a mounting piece, and a plurality of first mounting holes evenly distributed around the axis are opened on the surface of the mounting piece, a first opening is opened at the center position of the surface of one side wall of the flywheel housing relative to the mounting piece, a plurality of second mounting holes are opened on the surface of the flywheel housing located outside the first opening, and a second opening is opened on the surface of the side wall of the flywheel housing located on the side of the first opening.

[0009] Through the above technical solution, the first mounting hole on the mounting part is docked with the hole position of the transmission housing and fixed with bolts. Then the crankshaft of the engine is passed through the first opening, and the second mounting hole is docked with the hole position on the engine housing and then fixed with bolts. The second opening on the engine housing is designed for installing a guide wheel that matches the gear disc.

[0010] As a further solution of the present invention, a flywheel disc is provided inside the flywheel housing, and a gear disc is fixedly connected to the side wall surface of the flywheel disc. A plurality of internal fixing holes evenly distributed around the axis are opened on the side wall surface of the flywheel disc relative to the gear disc, and a plurality of external fixing holes are opened at the edge of the flywheel disc outside the internal fixing holes.

[0011] Through the above technical solution, the inner fixing hole on the flywheel is used to connect with the hole at the end of the crankshaft and then fixed with bolts, and the outer fixing hole on its surface is used to connect with the external clutch and then fixed with bolts.

[0012] As a further solution of the present invention, an observation tube is fixedly connected to the top of the flywheel housing, a plug is provided on the inner side of the observation tube, and a scale bar is fixedly connected to the outer wall surface of the flywheel disc.

[0013] Through the above technical solution, after disassembling and assembling the engine and flywheel, etc., alignment is required. At this time, the designated scale on the flywheel needs to be aligned with the middle position of the observation tube. At this time, the user can pull out the plug to perform positioning and structural design.

[0014] As a further solution of the present invention, a second filter plate is fixedly connected to the surface of one side wall of the dust box, a first filter plate is fixedly connected to the inside of the connecting piece on the side of the second cover body, and ear pieces are fixedly connected to the side wall surfaces of the flywheel housing located on the upper sides of the two connecting pieces.

[0015] Through the above technical solution, during the use of the flywheel disc, some powder will be generated due to the friction between the clutch friction plate and the flywheel. During the use of the flywheel disc, some powder will also be generated due to friction. These impurities cannot be effectively collected and cleaned, and thus accumulate inside the flywheel housing. In addition, in cases such as when the clutch is half-engaged, the clutch brake pad slips, and a large amount of heat will be generated due to friction. This heat cannot be effectively discharged, which may cause safety hazards. In this device, the user can turn on the fan, so that the external wind enters the flywheel housing after being filtered from the side of the first filter plate, and the powder and other impurities therein are taken away and enter the dust collection box. The second filter plate will intercept these powders and collect them therein. The user can regularly open the sealed door to clean the impurities inside the dust collection box. When the clutch is half-engaged, after the fan is running, it will continue to introduce external natural wind to blow through the clutch and flywheel disc, taking away the heat on their surface, thereby avoiding high-temperature sintering of the clutch brake pad and the like. The structural design is reasonable.

[0016] As a further solution of the present invention, spring shock absorbers are fixedly connected to the four corners of the bottom of the oil collecting tank, and a support is fixedly connected between the bottoms of the four spring shock absorbers. Connection holes are opened at the four corners of the surface of the support.

[0017] Through the above technical solution, during the use of the traditional flywheel housing structure, the oil inside the engine or transmission may leak into the flywheel housing due to aging of the internal sealing ring of the transmission and damage of the crankshaft oil seal. This part of the oil cannot be discharged and collected in a timely and effective manner, which may cause the clutch to slip, and thus affect the normal transmission of engine power. The device sets an oil inlet hole at the bottom of the flywheel housing, and uses a connecting pipe to discharge the oil leaked into the flywheel housing into the oil collecting tank in time for collection. The user can connect the liquid level sensor to the buzzer in advance. In this way, when the liquid level sensor detects the presence of oil in the oil collecting tank, it can promptly alarm to remind the user to pay attention and quickly deal with the leakage, and at the same time pour out the oil in the oil collecting tank to avoid danger and large losses. The spring shock absorber at the bottom of the oil collecting tank can reduce the shaking of the liquid inside the oil collecting tank caused by equipment vibration to a certain extent. The structural design is humanized and can help users reduce danger.

[0018] As a further solution of the present invention, a side pipe is fixedly connected to the surface of the flywheel housing located on one side of the observation tube, a limiting groove is provided on the inner wall of the side pipe, a movable part is provided inside the side pipe, a limiting block is fixedly connected to the surface of the movable part, the limiting block is slidably connected to the limiting groove, and a locking tooth is fixedly connected to the bottom surface of the limiting block.

[0019] Through the above technical solution, when the flywheel is reinstalled after repair, it is necessary to align the flywheel and then fix it to the end of the crankshaft with bolts. In the traditional structure, in order to prevent the flywheel from deflecting when tightening the bolts, it is generally necessary to prepare in advance a setting to clamp the sprocket. In this structure, the user can quickly rotate the threaded rod to extend the end of the movable part into the flywheel housing so that the teeth clamp the sprocket. The structural design is conducive to quick operation of workers, and there is no need to worry about not having a limit mechanism prepared in advance.

[0020] As a further solution of the present invention, the latching teeth match the gear ring, the side pipe is fixedly connected to a threaded sleeve through a connecting block, the threaded sleeve is internally threaded with a threaded rod, and the end of the threaded rod is rotatably connected to the top of the movable part.

[0021] Through the above technical solution, the movable part can be driven to move inside the side pipe by rotating the threaded rod, so that the latching teeth can be stuck in the gear disc or the latching teeth can be separated from the flywheel housing.

[0022] Compared with related technologies, the engine power output device provided by the present invention has the following beneficial effects:

[0023] 1. In the present invention, during the use of the flywheel disc, some powder will be generated due to the friction between the clutch friction plate and the flywheel. During the use of the flywheel disc ring gear, some powder will also be generated due to the friction. These impurities cannot be effectively collected and cleaned, and thus accumulate inside the flywheel housing. In addition, when the clutch is half-engaged, the clutch brake pad will slip, and a large amount of heat will be generated due to friction. This heat cannot be effectively discharged, which may cause safety hazards. In this device, the user can turn on the fan, so that the external air passes through the first filter plate and enters the flywheel housing after being filtered, and the powder and other impurities therein are taken away and then enter the dust collection box. The second filter plate will intercept the powder and collect it therein. The user can regularly open the sealed door to clean the impurities inside the dust collection box. When the clutch is half-engaged, after the fan is running, it will continue to introduce external natural wind to blow through the clutch and flywheel disc, and take away the heat on their surface, thereby avoiding high-temperature sintering of the clutch brake pad and the like. The structural design is reasonable.

[0024] 2. In the present invention, during use, the traditional flywheel housing structure may cause the oil inside the engine or transmission to leak into the flywheel housing due to aging of the internal sealing ring of the transmission and damage of the crankshaft oil seal. This part of the oil cannot be discharged and collected in a timely and effective manner, which may cause the clutch to slip, thereby affecting the normal transmission of engine power. The device is provided with an oil inlet hole at the bottom of the flywheel housing, and uses a connecting pipe to discharge the oil leaked into the flywheel housing into the oil collecting tank in time for collection. The user can connect the liquid level sensor with the buzzer in advance. In this way, when the liquid level sensor detects the presence of oil in the oil collecting tank, it can timely alarm to remind the user to pay attention and quickly deal with the leakage. At the same time, the oil in the oil collecting tank can be poured out to avoid danger and large losses. The spring shock absorber at the bottom of the oil collecting tank can reduce the shaking of the liquid inside the oil collecting tank caused by equipment vibration to a certain extent. The humanized structural design can help users reduce the occurrence of danger.

[0041] As shown in Figure 1-9 , one end of the flywheel shell 1 is fixedly connected with the mounting piece 2, the surface of the mounting piece 2 is provided with a plurality of first mounting holes 3 which are uniformly distributed around the shaft center, the surface center position of the side wall of the flywheel shell 1 relative to the mounting piece 2 is provided with a first through hole 18, the surface of the flywheel shell 1 outside the first through hole 18 is provided with a plurality of second mounting holes 19, and the surface of the side wall of the flywheel shell 1 on one side of the first through hole 18 is provided with a second through hole 20.

[0042] The first mounting hole 3 on the mounting piece 2 is butt jointed with the hole position of the transmission shell and is fixed by bolts, then the crankshaft of the engine is passed through the first through hole 18, and the second mounting hole 19 is butt jointed with the hole position on the engine shell, and then is fixed by bolts, and the second through hole 20 on the engine shell is designed for installing the guide wheel matched with the toothed disc 25.

[0043] As shown in Figure 1-9As shown, a flywheel disc 4 is provided inside the flywheel housing 1, and a gear disc 25 is fixedly connected to the side wall surface of the flywheel disc 4. A plurality of internal fixing holes 5 are opened on the side wall surface of the flywheel disc 4 relative to the gear disc 25 and are evenly distributed around the axis. A plurality of external fixing holes 26 are opened on the edge of the flywheel disc 4 outside the internal fixing holes 5.

[0044] The inner fixing hole 5 on the flywheel 4 is used to connect with the hole at the end of the crankshaft and then be fixed with bolts. The outer fixing hole 26 on its surface is used to connect with the external clutch and then be fixed with bolts.

[0045] like Figure 1-9 As shown, an observation tube 7 is fixedly connected to the top of the flywheel housing 1 , a plug 22 is provided on the inner side of the observation tube 7 , and a scale bar 27 is fixedly connected to the outer wall surface of the flywheel disc 4 .

[0046] At present, after disassembling and assembling the engine and the flywheel 4, alignment is required. At this time, the designated scale on the flywheel 4 needs to be aligned with the middle position of the observation tube 7. At this time, the user can remove the plug 22 to perform positioning and structural design.

[0047] like Figure 1-9 As shown, a second filter plate 36 is fixedly connected to a side wall surface of the dust box 14, a first filter plate 17 is fixedly connected to the inside of the connecting piece 16 on the side relative to the second cover body 33, and an ear piece 6 is fixedly connected to the side wall surface of the flywheel housing 1 located on the upper side of the two connecting pieces 16.

[0048] During the use of the flywheel disc 4, some powder will be generated due to the friction between the clutch friction plate and the flywheel. The flywheel disc 4 ring gear will also generate some powder due to friction during use. These impurities cannot be effectively collected and cleaned, and thus accumulate inside the flywheel housing 1. In addition, when the clutch is half-engaged, the clutch brake pad slips, and a large amount of heat will be generated due to friction. This heat cannot be effectively discharged, which may cause safety hazards. In this device, the user can turn on the fan 13, so that the external wind enters the flywheel housing 1 after being filtered from the side of the first filter plate 17, and takes away the powder and other impurities therein and enters the dust collection box. The second filter plate 36 will intercept these powders and collect them therein. The user can regularly open the sealing door 35 to clean the impurities inside the dust collection box. When the clutch is half-engaged, after the fan 13 is running, it will continue to introduce external natural wind to blow through the clutch and flywheel disc 4, taking away the heat on their surface, thereby avoiding high-temperature sintering of the clutch brake pad and the like. The structural design is reasonable.

[0049] like Figure 1-9As shown, spring shock absorbers 30 are fixedly connected to the four corners of the bottom of the oil collecting tank 12, and support members 21 are fixedly connected between the bottoms of the four spring shock absorbers 30. Connection holes are opened at the four corners of the surface of the support member 21.

[0050] During use, the traditional flywheel housing 1 structure may cause the oil inside the engine or transmission to leak into the flywheel housing 1 due to aging of the internal sealing ring of the transmission and damage to the crankshaft oil seal. This part of the oil cannot be discharged and collected in a timely and effective manner, which may cause the clutch to slip, thereby affecting the normal transmission of engine power. The device is provided with an oil inlet hole 10 at the bottom of the flywheel housing 1, and uses a connecting pipe 11 to discharge the oil leaked into the flywheel housing 1 into the oil collecting tank 12 for collection in time. The user can connect the liquid level sensor 29 to the buzzer in advance. In this way, when the liquid level sensor 29 detects the presence of oil in the oil collecting tank 12, it can promptly alarm to remind the user to pay attention and quickly deal with the leakage, and at the same time pour out the oil in the oil collecting tank 12 to avoid danger and large losses. The spring shock absorber 30 at the bottom of the oil collecting tank 12 can reduce the shaking of the liquid inside the oil collecting tank 12 caused by equipment vibration to a certain extent. The structural design is humanized and can help users reduce danger.

[0051] like Figure 1-9 As shown, the surface of the flywheel housing 1 located on the side of the observation tube 7 is fixedly connected to the side pipe 15, and a limiting groove 41 is provided on the inner wall of the side pipe 15. A movable part 38 is provided inside the side pipe 15, and a limiting block 39 is fixedly connected to the surface of the movable part 38. The limiting block 39 is slidably connected to the limiting groove 41, and the bottom surface of the limiting block 39 is fixedly connected to a locking tooth 40.

[0052] When the flywheel 4 is reinstalled after repair, it is necessary to align the flywheel 4 and then fix it to the end of the crankshaft with bolts. In the traditional structure, in order to prevent the flywheel 4 from deflecting when tightening the bolts, it is generally necessary to prepare in advance to clamp the sprocket 25. In this structure, the user can quickly rotate the threaded rod 23 to allow the end of the movable part 38 to extend into the inside of the flywheel housing 1, so that the locking teeth 40 clamp the sprocket 25. The structural design is conducive to quick operation by workers, and there is no need to worry about not preparing a limit mechanism in advance.

[0053] like Figure 1-9 As shown, the latching teeth 40 match the gear ring, the side pipe 15 is fixedly connected to the threaded sleeve 37 through the connecting block, the threaded sleeve 37 is internally threadedly connected to the threaded rod 23, and the end of the threaded rod 23 is rotatably connected to the top of the movable part 38.

[0054] By rotating the threaded rod 23 , the movable member 38 can be driven to move inside the side pipe 15 , so that the latching teeth 40 can be clamped on the gear plate 25 or the latching teeth 40 can be separated from the flywheel housing 1 .

[0055] The working principle of an engine power output device provided by the present invention is as follows:

[0056] Step 1: During the use of the flywheel disc 4, some powder will be generated due to the friction between the clutch friction plate and the flywheel. The flywheel disc 4 ring gear will also generate some powder due to friction during use. These impurities cannot be effectively collected and cleaned, and thus accumulate inside the flywheel housing 1. In addition, when the clutch is half-engaged, the clutch brake pad will slip, and a large amount of heat will be generated due to friction. This heat cannot be effectively discharged, which may cause safety hazards. In this device, the user can turn on the fan 13, so that the external air enters the flywheel housing 1 after being filtered from the side of the first filter plate 17, and the powder and other impurities therein are taken away and then enter the dust collection box. The second filter plate 36 will intercept the powder and collect it therein. The user can regularly open the sealing door 35 to clean the impurities inside the dust collection box. When the clutch is half-engaged, after the fan 13 is running, it will continue to introduce external natural wind to blow through the clutch and flywheel disc 4, taking away the heat on their surface, thereby avoiding high-temperature sintering of the clutch brake pad and the like. The structural design is reasonable.

[0057] Step 2: During the use of the traditional flywheel housing 1 structure, the oil inside the engine or transmission may leak into the flywheel housing 1 due to aging of the internal sealing ring of the transmission and damage to the crankshaft oil seal. This part of the oil cannot be discharged and collected in a timely and effective manner, which may cause the clutch to slip, thereby affecting the normal transmission of the engine power. The device is provided with an oil inlet hole 10 at the bottom of the flywheel housing 1, and uses a connecting pipe 11 to discharge the oil leaked into the flywheel housing 1 into the oil collecting tank 12 for collection in time. The user can connect the liquid level sensor 29 to the buzzer in advance. In this way, when the liquid level sensor 29 detects the presence of oil in the oil collecting tank 12, it can promptly alarm to remind the user to pay attention and quickly deal with the leakage. At the same time, the oil in the oil collecting tank 12 is poured out to avoid danger and large losses. The spring shock absorber 30 at the bottom of the oil collecting tank 12 can reduce the shaking of the liquid inside the oil collecting tank 12 caused by equipment vibration to a certain extent. The humanized structural design can help users reduce danger.

[0058] Step 3: When the flywheel 4 is reinstalled after repair, it is necessary to align the flywheel 4 and then fix it to the end of the crankshaft with bolts. In the traditional structure, in order to prevent the flywheel 4 from deflecting when tightening the bolts, it is generally necessary to prepare in advance to clamp the sprocket 25. In this structure, the user can quickly rotate the threaded rod 23 to allow the end of the movable part 38 to extend into the inside of the flywheel housing 1, so that the locking teeth 40 clamp the sprocket 25. The structural design is conducive to quick operation by workers, and there is no need to worry about not having a limit mechanism prepared in advance.
