DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] Please refer to Figures 1 to 4 , Figure 1 A front view of the gear chamber provided by the present invention; Figure 2 for Figure 1 Side view of Figure 3 for Figure 1 Rear view of Figure 4 for Figure 1 Schematic diagram of the structure of the middle shell.

[0026] The present invention provides a gear chamber, such as Figures 1 to 4 The gear chamber includes: a housing 1; a fuel pump 2 provided on the outer side of the housing 1 to supply fuel to the engine; an air compression pump 3 provided on the outer side of the housing 1 to compress air; a crankshaft gear 4 provided in the housing 1 to output engine power; an oil pump gear 21 provided in the housing 1 to drive the fuel pump 2 through the crankshaft gear 4; an air compression pump gear 31 provided in the housing 1 to drive the air compression pump 3 through the crankshaft gear 4. Specifically, the housing 1 is in an open shape, and the size of the opening of the housing 1 is consistent with the size of its edge contour, so that Figure 1 From the perspective of the engine, the crankshaft gear 4 is arranged at the bottom of the right side of the housing 1 and is connected to the crankshaft connecting rod mechanism of the engine. The fuel pump 2 and the air compression pump 3 are arranged on the left side of the housing 1, and the fuel pump 2 is located above the air compression pump 3. Preferably, the fuel pump 2 and the air compression pump 3 are fixed to the outer side of the housing 1 by bolts. Accordingly, the oil pump gear 21 used to drive the operation of the fuel pump 2 and the air compression pump gear 31 used to drive the operation of the air compression pump 3 are arranged on the left side of the housing 1. Among them, the structure and principle of the crankshaft connecting rod mechanism of the engine can refer to the existing technology, which will not be expanded in this article.

[0027] It should be noted that the housing 1 is provided with gear mounting grooves for accommodating the crankshaft gear 4, the oil pump gear 21 and the air pump gear 31. Specifically, Figure 4 As shown, the first gear mounting groove 11 is used to place the crankshaft gear 4, the second gear mounting groove 12 is used to place the air pump gear 31, and the third gear mounting groove 13 is used to place the oil pump gear 21. The gear shaft of the air pump gear 31 passes through the second gear mounting groove 12 and is connected to the air compression pump 3, and the gear shaft of the oil pump gear 21 passes through the third gear mounting groove 13 and is connected to the fuel pump 2.

[0028] It can be seen that since the fuel pump 2 and the air compression pump 3 are fixed to the housing 1, that is, the fuel pump 2 and the air compression pump 3 are supported and fixed by the housing 1, there is no need to set up additional brackets for supporting the fuel pump 2 and the air compression pump 3 in the power system, so that the number of components in the entire power system is reduced, the structure of the power system is simplified, and the power system is easy to assemble and maintain.

[0029] If the air pump gear 31 and the oil pump gear 21 are directly meshed with the crankshaft gear 4, the sizes of the three gears will need to be designed to be larger, which will increase the manufacturing difficulty and production cost of the gears, and will also make the sizes of the three gear installation slots opened in the housing 1 larger, which will reduce the rigidity of the housing 1. In order to avoid the above situation, if Figure 1 As shown, the gear chamber further includes: an air pump idler gear 32 disposed in the housing 1 and meshing with both the crankshaft gear 4 and the air pump gear 31; and a double gear 5 disposed in the housing 1 and meshing with both the crankshaft gear 4 and the oil pump gear 21. Specifically, the air pump idler gear 32 is added between the crankshaft gear 4 and the air pump gear 31 to reduce the size and space occupied by the crankshaft gear 4 and the air pump gear 31, and the double gear 5 is added between the crankshaft gear 4 and the oil pump gear 21 to reduce the size and space occupied by the crankshaft gear 4 and the oil pump gear 21, so as to reduce the size of the three gear installation slots provided on the housing 1, improve the rigidity of the housing 1, and thus facilitate the housing 1 to support the fuel pump 2 and the air compression pump 3.

[0030] It should be noted that, during the transmission process from the crankshaft gear 4 to the oil pump gear 21, Figure 1 As shown, the crankshaft gear 4 meshes with the gear teeth at the outer edge of the large gear plate of the duplex gear 5, and the oil pump gear 21 meshes with the gear teeth at the outer edge of the small gear plate of the duplex gear 5; wherein, compared with the above-mentioned large gear plate, the above-mentioned small gear plate is located closer to the inside of the housing 1.

[0031] like Figures 1 to 3 As shown, the gear chamber also includes: a first camshaft idler gear 6 disposed in the housing 1 and meshing with the double gear 5; and a second camshaft idler gear 7 disposed outside the housing 1 and meshing with both the camshaft gear and the first camshaft idler gear 6. The crankshaft gear 4 realizes the rotation of the camshaft gear through the double gear 5, the first camshaft idler gear 6 and the second camshaft idler gear 7 in sequence, so that the camshaft, which can be regarded as the same rotating body as the camshaft gear, rotates, and then drives the valve switch to control the intake and exhaust of the engine. Among them, the structure and principle function of the camshaft gear, camshaft and valve switch can refer to the existing technology, and will not be repeated in this article.

[0032] It should be noted that Figures 1 to 3 From the perspective of , the second camshaft idler gear 7 is arranged at the top of the housing 1, and the top of the housing 1 should be provided with a through groove for the second camshaft idler gear 7 to pass through so as to engage with the first camshaft idler gear 6; the first camshaft idler gear 6 is engaged with the teeth at the outer edge of the small gear plate of the double gear 5.

[0033] Since there is no gear installation slot for accommodating the air pump idle gear 32, the double gear 5 and the first camshaft idle gear 6 in the housing 1, and there is no gear installation slot for accommodating the crankshaft gear 4, the oil pump gear 21 and the air pump gear 31, in order to improve the strength of the support for the above three gears, as shown in FIG. Figure 4 As shown, the gear chamber further includes a support rib 14 disposed in the housing 1 for supporting the gear shafts of the air pump idle gear 32, the double gear 5, and the first camshaft idle gear 6. Specifically, a plurality of fixing holes 19 for fixing the support rib 14 are provided on the port surface of the housing 1, one end of the support rib 14 is fixed in the fixing hole 19 by a bolt, and the other end of the support rib 14 is used to support the gear shaft of one of the above three gears.

[0034] Taking the first camshaft idler gear 6 as an example, Figure 4 As shown, three supporting ribs 14 are preferably used to support the gear shaft of the first camshaft idler gear 6, wherein the first ends of two supporting ribs 14 are fixed in the fixing holes 19, and the first end of another supporting rib 14 is used to support the gear shaft of the double gear 5, and the second ends of the above three supporting ribs 14 form a supporting hole for supporting and allowing the gear shaft of the first camshaft idler gear 6 to pass through and rotate, so as to improve the supporting strength of the first camshaft idler gear 6.

[0035] Regarding the double gear 5, Figure 4 As shown, it is also preferred to use three supporting ribs 14 to support the gear shaft of the double gear 5, and the first ends of the three supporting ribs 14 form a supporting hole for supporting and allowing the gear shaft of the double gear 5 to pass through and rotate. The second end of one of the supporting ribs 14 is fixed in the fixing hole 19, and the second end of another supporting rib 14 is used to support the gear shaft of the first camshaft idler gear 6, and the second end of the last supporting rib 14 is used to support the gear shaft of the air compressor idler gear 32.

[0036] For the air pump idler gear 32, Figure 4 As shown, it is still preferred to use three support ribs 14 to support the gear shaft of the air compressor idler gear 32. The first ends of the three support ribs 14 form a support hole for supporting and allowing the gear shaft of the air compressor idler gear 32 to pass through and rotate. The second ends of two support ribs 14 are fixed in the fixing hole 19, and the second end of the other support rib 14 is used to support the gear shaft of the above-mentioned double gear 5.

[0037] It should be noted that the number of the support ribs 14 for strengthening the support of the first camshaft idler gear 6, the double gear 5 and the air pump idler gear 32 is set to three only as an example, and the number can be set according to actual conditions.

[0038] like Figure 3As shown, the outer side of the housing 1 is provided with a gear oil supply pipe; wherein, the gear oil supply pipe comprises: a main oil pipe 15, a first auxiliary oil pipe 16 and a second auxiliary oil pipe 17. Specifically, the first end of the main oil pipe 15 has an oil inlet 151 for oil to flow in, and the second end of the main oil pipe 15 has a double oil supply port 152 for lubricating the double gears 5. The oil inlet 151 is connected to the oil pump of the engine, and the oil pump pumps the oil into the main oil pipe 15 from the oil inlet 151, and the oil flows out from the double oil supply port 152 along the main oil pipe 15, so that the oil lubricates the double gears 5; the first end of the first auxiliary oil pipe 16 is connected to the second end of the main oil pipe 15, and the second end of the first auxiliary oil pipe 16 has an air compressor idler gear oil supply port 161 for lubricating the air compressor pump idler gear 32. The oil from The second end of the main oil pipe 15 flows into the first auxiliary oil pipe 16 and flows along the first auxiliary oil pipe 16, and finally the engine oil flows out from the air compressor idler oil supply port 161 to lubricate the air compressor idler gear 32; the first end of the second auxiliary oil pipe 17 is connected to the second end of the main oil pipe 15, and the second end of the second auxiliary oil pipe 17 has a camshaft idler oil supply port 171 for lubricating the first camshaft idler gear 6. The engine oil is diverted from the second end of the main oil pipe 15 and flows into the second auxiliary oil pipe 17 and flows along the second auxiliary oil pipe 17, and finally the engine oil flows out from the camshaft idler oil supply port 171 to lubricate the first camshaft idler gear 6.

[0039] It should be noted that Figure 3 From the perspective of , the above-mentioned oil inlet 151 is located on the left side above the crankshaft gear 4, so as to be connected to the engine oil pump, and the main oil pipe 15 extends from this position toward the double gear 5; the first auxiliary oil pipe 16 extends from the double gear 5 toward the air compressor idler gear 32; the second auxiliary oil pipe 17 extends from the double gear 5 toward the first camshaft idler gear 6; the above-mentioned double oil supply port 152, the air compressor idler gear oil supply port 161 and the camshaft idler gear oil supply port 171 should pass through the housing 1, so that the oil can reach the inside of the housing 1 from the outer side of the housing 1, thereby realizing the lubrication of the above-mentioned gears.

[0040] like Figure 3 As shown, an oil distribution port 162 is provided between the first end and the second end of the first auxiliary oil pipe 16, and the gear chamber further includes an air pump oil supply pipe 33 which is communicated with the oil distribution port 162 and connected to the air compression pump 3 for lubricating the air compression pump 3.

[0041] like Figure 3As shown, the outer side of the housing 1 is also provided with a power take-off oil supply pipe 18 for supplying oil to the power take-off; wherein the first end of the power take-off oil supply pipe 18 is connected to the second end of the second auxiliary oil pipe 17, and the second end of the power take-off oil supply pipe 18 has a power take-off oil supply port 181 for lubricating the power take-off. Specifically, a portion of the oil in the second auxiliary oil pipe 17 flows into the power take-off oil supply pipe 18, and flows out of the housing 1 from the power take-off oil supply port 181, and the outflowing oil is guided into the power take-off through a dedicated oil supply pipeline, thereby finally achieving lubrication of the power take-off. Figure 3 From the perspective of , the power take-off is arranged above the engine oil pump, and the power take-off oil supply pipe 18 extends from the camshaft idler oil supply port 171 toward the power take-off.
