Description

Technical Field

[0001] This utility model relates to the technical field of turbocharger drive structure, and in particular to a turbocharger drive structure with lubrication function. Background Technology

[0002] Mechanical supercharging technology is being used more and more widely in the motorcycle industry. It can effectively improve the power output of motorcycles. The most common type is the turbocharger, which uses the rotation of a centrifugal impeller to compress air at high speed to achieve supercharging.

[0003] In existing supercharged motorcycles, the supercharger is mostly driven by chain drive. As the usage time increases, the chain will gradually lengthen due to continuous force and friction, resulting in a loose chain. This not only reduces transmission efficiency and causes power loss, affecting the motorcycle's power performance, but also accelerates the wear of the chain and sprocket, shortening their service life. In addition, chain drive is usually accompanied by a lot of operating noise. Utility Model Content

[0004] To solve the above problems, this utility model provides a turbocharger drive structure with lubrication function.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a turbocharger drive structure with lubrication function, comprising a turbocharger body, a drive gear fixedly sleeved on the connecting shaft of the turbocharger body rotor, a first gear rotatably mounted on the turbocharger body and meshing with the drive gear, a second gear rotatably mounted on the turbocharger body and meshing with the first gear, a drive assembly for driving the second gear to rotate in a gear transmission manner provided on the turbocharger body, and a lubrication tank for storing lubricating oil fixed on the turbocharger body, wherein the drive gear, the first gear, and the second gear are all rotatably mounted in the lubrication tank.

[0006] By adopting the above technical solution, the operating drive component drives the second gear to rotate in a gear transmission mode, which in turn drives the first gear meshing with the second gear, the drive gear meshing with the first gear, and the rotor connecting shaft fixed to the drive gear to rotate. This allows the supercharger body to perform supercharging work normally. By changing the existing chain drive to a gear drive, the gradual elongation of the chain due to continuous force and friction is avoided, which would cause the chain to become too loose, resulting in power loss, affecting the motorcycle's power performance, and aggravating the wear of the chain and sprockets. This ensures transmission efficiency. In addition, the lubricating oil in the lubrication box continuously lubricates the drive gear, the first gear, the second gear, and other transmission components, further reducing mechanical wear between the drive gear, the first gear, and the second gear, extending their service life, and reducing the noise caused by the transmission between the drive gear, the first gear, and the second gear.

[0007] Furthermore, the drive assembly includes a balance shaft disposed on one side of the supercharger body, a third gear fixedly sleeved on the balance shaft and meshing with the second gear, a crankshaft disposed on one side of the balance shaft, and a main gear fixedly sleeved on the crankshaft and meshing with the third gear. The balance shaft and the crankshaft are both located in the crankcase. The crankshaft is driven by the reciprocating motion of the piston of the motorcycle engine. The third gear and the main gear are both located in the lubrication box.

[0008] By adopting the above technical solution, the reciprocating motion of the motorcycle engine piston drives the crankshaft to rotate, which in turn drives the main gear fixed to the crankshaft, the third gear meshing with the main gear, the balance shaft fixed with the third gear, and the second gear meshing with the main gear to rotate, thereby ensuring the normal rotation of the drive gear. The entire power source is driven by the engine piston, eliminating the need for the additional drive shaft in existing chain drive technology, making the whole more compact and reducing the overall space occupied.

[0009] Furthermore, the lubrication tank is provided with a filtration mechanism, which includes a filtration assembly. The filtration assembly includes a filter cylinder disposed at and connected to the bottom of the lubrication tank, a filter plate disposed inside the filter cylinder, and an oil outlet pipe that rotates and is connected to the bottom of the filter cylinder. The filtration mechanism also includes an oil extraction assembly for draining the lubricating oil in the oil outlet pipe back into the lubrication tank.

[0010] By adopting the above technical solution, the lubricating oil in the lubrication tank flows into the filter cartridge under the action of gravity, and then flows from the filter cartridge into the oil outlet pipe. During this process, the filter plate will block the debris generated by the wear between the transmission components in the lubricating oil. Finally, the oil suction assembly is operated to discharge the lubricating oil in the oil outlet pipe back into the lubrication tank for lubrication, reducing the probability of wear between the transmission components caused by debris in the lubricating oil.

[0011] Furthermore, the oil extraction assembly includes a sealing box fixed to the lubrication tank, an oil supply pipe fixed and connected to the sealing box, a sealing piston slidably disposed within the sealing box, and a connecting rod that passes through the sealing box and slides in cooperation with the sealing box. The other end of the oil supply pipe is fixedly connected to the lubrication tank, the upper end of the oil outlet pipe is fixedly connected to the sealing box, the connecting rod is fixed to the sealing piston, and a one-way valve is provided on the oil outlet pipe to control the lubricating oil to be discharged from the oil outlet pipe into the sealing box. A one-way valve is provided on the oil supply pipe to control the lubricating oil to be discharged from the oil supply pipe into the sealing box. The filtering mechanism also includes a displacement component for driving the connecting rod to reciprocate.

[0012] By adopting the above technical solution, the displacement component drives the connecting rod to reciprocate, which in turn drives the sealed piston fixed to the connecting rod to reciprocate. In this process, the lubricating oil is first drawn into the sealing box from the oil outlet pipe, then discharged from the sealing box to the oil supply pipe, and finally discharged from the oil supply pipe to the lubrication box to ensure the normal lubrication of the lubricating oil.

[0013] Furthermore, the displacement assembly includes a drive shaft that passes through and is rotatably connected to the lubrication box, an adjustment disc that is fixedly sleeved on the drive shaft, and an adjustment column that is set on the connecting rod. The drive shaft is fixed and coaxially arranged with the drive gear. An adjustment groove that is eccentrically arranged on the drive shaft is provided on the drive shaft. The adjustment column passes through the adjustment groove and slides in fit.

[0014] By adopting the above technical solution, during the rotation of the drive gear, the drive shaft fixed to the drive gear and the adjustment plate fixed to the drive shaft rotate synchronously. Since the adjustment groove is eccentrically set with the drive shaft and the adjustment groove is slidably set with the adjustment column, the adjustment column and the connecting rod connected to the adjustment column move towards or away from the axis of the drive shaft, thereby ensuring the normal circulation of lubricating oil.

[0015] Furthermore, a connecting cylinder fixed to the lubrication box is provided through the bottom of the lubrication box, the filter cylinder is threadedly connected to the connecting cylinder, an oil drain hole is provided on the side wall of the connecting cylinder, a notch communicating with the oil drain hole is provided at the upper end of the filter cylinder, and a shielding component is provided on the connecting cylinder.

[0016] By adopting the above technical solution, the lubricating oil in the lubrication box passes through the oil drain hole and notch in sequence and finally enters the filter cylinder. The debris in the lubricating oil will remain on the top of the filter plate. By rotating the filter cylinder until it separates from the connecting cylinder, the debris on the filter plate can be cleaned so that the filter plate can perform filtering work normally.

[0017] Furthermore, the shielding assembly includes a sealing block slidably disposed within the connecting cylinder and a spring fixed between the sealing block and the inner top wall of the connecting cylinder and in a retracted state, wherein the bottom of the sealing block abuts against the upper end of the filter cylinder.

[0018] By adopting the above technical solution, during the descent of the filter cartridge, the spring gradually extends, thereby driving the sealing block connected to the spring to descend. Finally, the sealing block moves to the position corresponding to the oil drain hole, thereby reducing the probability of lubricating oil in the lubrication box overflowing from the oil drain hole.

[0019] Furthermore, the adjusting column passes through the connecting rod and is rotatably connected to the connecting rod.

[0020] By adopting the above technical solution, the adjusting column and the connecting rod are rotatably connected, which reduces the friction between the adjusting column and the adjusting groove when the adjusting column moves.

[0021] Furthermore, multiple grooves are formed on the side wall of the filter cartridge.

[0022] By adopting the above technical solution, the groove design reduces the probability of slippage when rotating the filter cylinder.

[0023] Furthermore, the distance between the top and bottom of the sealing block is greater than the distance between the top wall and the bottom wall of the oil drain hole.

[0024] In summary, this utility model has the following beneficial effects: In this application, by changing the chain drive to a gear drive, the chain is prevented from gradually stretching due to continuous force and friction, which would cause the chain to become too loose, resulting in power loss, affecting the power performance of the motorcycle, and aggravating the wear of the chain and sprocket, thus ensuring transmission efficiency.

[0027] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0028] Example 1: As Figure 1-2As shown in the figure, this application discloses a turbocharger drive structure with lubrication function, including a turbocharger body 1 and a drive assembly 5. A drive gear 2 is fixedly sleeved on the connecting shaft of the rotor of the turbocharger body 1. A first gear 3 that meshes with the drive gear 2 is rotatably mounted on the turbocharger body 1, and a second gear 4 that meshes with the first gear 3 is rotatably mounted on the turbocharger body 1. A lubrication tank 6 for storing lubricating oil is fixed on the turbocharger body 1, and the drive gear 2, the first gear 3, and the second gear 4 are all rotatably disposed within the lubrication tank 6. A rotating shaft is fixed on both the first gear 3 and the second gear 4, and the rotating shafts on the first gear 3 and the second gear 4 pass through the lubrication tank 6 and are rotatably connected. The rotating shafts on the first gear 3 and the second gear 4 are rotatably connected to the turbocharger body 1, and the rotor connecting shaft on the drive gear 2 passes through the lubrication tank 6 and is rotatably connected to the lubrication tank 6. The operating drive assembly 5 drives the second gear 4 to rotate via gear transmission, which in turn drives the first gear 3 meshing with the second gear 4, the drive gear 2 meshing with the first gear 3, and the rotor connecting shaft fixed to the drive gear 2 to rotate. This allows the supercharger body 1 to perform supercharging normally. By changing the existing chain drive to gear drive, the gradual elongation of the chain due to continuous force and friction is avoided, which would lead to a loose chain, power loss, and affect the motorcycle's power performance. It would also prevent the chain and sprocket from wearing out, thus ensuring transmission efficiency. In addition, the lubricating oil in the lubrication box 6 continuously lubricates the drive gear 2, the first gear 3, the second gear 4, and other transmission components, further reducing mechanical wear between the drive gear 2, the first gear 3, and the second gear 4, extending their service life, and reducing the noise caused by the transmission between the drive gear 2, the first gear 3, and the second gear 4.

[0029] The drive assembly 5 is mounted on the supercharger body 1 and is used to drive the second gear 4 to rotate via gear transmission. The drive assembly 5 includes a balance shaft 51, a third gear 52, a crankshaft 53, and a main gear 54. The balance shaft 51 is located on one side of the supercharger body 1. The third gear 52 is fixedly mounted on the balance shaft 51 and meshes with the second gear 4. The crankshaft 53 is located on one side of the balance shaft 51. Both the balance shaft 51 and the crankshaft 53 are located within the crankcase, and the crankshaft 53 is driven by the reciprocating motion of the motorcycle engine piston. The main gear 54 is fixedly mounted on the crankshaft 53 and meshes with the third gear 52. Both the third gear 52 and the main gear 54 are located within the lubrication box 6. The reciprocating motion of the motorcycle engine piston drives the crankshaft 53 to rotate, which in turn drives the main gear 54 fixed to the crankshaft 53, the third gear 52 meshing with the main gear 54, the balance shaft 51 fixed with the third gear 52, and the second gear 4 meshing with the main gear 54 to rotate, thereby ensuring the normal rotation of the drive gear 2. The entire power source is driven by the engine piston, eliminating the need for the existing chain drive technology to add a separate drive shaft 731, making the whole more compact and reducing the overall space occupied.

[0030] Example 2: Figure 3-6 As shown in the illustration, this application discloses a turbocharger drive structure with lubrication function, including a filter mechanism 7 and a shielding assembly 9. The filter mechanism 7 is disposed on a lubrication tank 6 and includes a filter assembly 71, an oil extraction assembly 72, and a displacement assembly 73. The filter assembly 71 includes a filter cylinder 711, a filter plate 712, and an oil outlet pipe 713. The filter cylinder 711 is disposed at the bottom of the lubrication tank 6 and is connected to it. The filter plate 712 is disposed inside the filter cylinder 711, and the oil outlet pipe 713 rotates and is connected to the bottom of the filter cylinder 711. Under the action of gravity, the lubricating oil in the lubrication tank 6 flows into the filter cylinder 711 and then flows from the filter cylinder 711 into the oil outlet pipe 713. During this process, the filter plate 712 blocks the debris generated by the wear between the transmission components in the lubricating oil. Finally, the oil extraction assembly 72 is operated to discharge the lubricating oil in the oil outlet pipe 713 back into the lubrication tank 6 for lubrication, reducing the probability of wear between the transmission components caused by debris in the lubricating oil.

[0031] The oil extraction assembly 72 is used to drain the lubricating oil in the oil outlet pipe 713 back into the lubrication tank 6. The oil extraction assembly 72 includes a sealing box 721, an oil supply pipe 722, a sealing piston 723, and a connecting rod 724. The sealing box 721 is fixed to the lubrication tank 6, and the upper end of the oil outlet pipe 713 is fixed to and connected to the sealing box 721. A one-way valve is provided on the oil outlet pipe 713 to control the lubricating oil to be discharged from the oil outlet pipe 713 into the sealing box 721. The oil supply pipe 722 is fixed to and connected to the sealing box 721. A one-way valve is provided on the oil supply pipe 722 to control the lubricating oil to be discharged from the oil supply pipe 722 into the sealing box 721. The other end of the oil supply pipe 722 is fixedly connected to the lubrication tank 6. The sealing piston 723 is slidably disposed within the sealing box 721. The connecting rod 724 passes through the sealing box 721 and slides in cooperation with the sealing box 721. The connecting rod 724 is fixed to the sealing piston 723. The operating displacement component 73 drives the connecting rod 724 to reciprocate, which in turn drives the sealed piston 723 fixed to the connecting rod 724 to reciprocate. During this process, the lubricating oil is first drawn into the sealing box 721 through the oil outlet pipe 713, then discharged from the sealing box 721 to the oil supply pipe 722, and finally discharged from the oil supply pipe 722 to the lubrication box 6 to ensure the normal lubrication of the lubricating oil.

[0032] The displacement assembly 73 drives the connecting rod 724 to reciprocate. The displacement assembly 73 includes a drive shaft 731, an adjusting disc 732, and an adjusting column 733. The drive shaft 731 is rotatably connected to the lubrication box 6 and is fixed to and coaxially arranged with the drive gear 2. An adjusting groove 8 is provided on the drive shaft 731, eccentrically positioned therefrom. The adjusting column 733 passes through the adjusting groove 8 and slides within it. The adjusting disc 732 is fixedly sleeved on the drive shaft 731, and the adjusting column 733 is mounted on the connecting rod 724. During the rotation of the drive gear 2, the drive shaft 731 fixed to the drive gear 2 and the adjustment plate 732 fixed to the drive shaft 731 rotate synchronously. Since the adjustment groove 8 is eccentrically set with the drive shaft 731, and the adjustment groove 8 is slidably set with the adjustment column 733, the adjustment column 733 and the connecting rod 724 connected to the adjustment column 733 move towards or away from the axis of the drive shaft 731, thereby ensuring the normal circulation of lubricating oil.

[0033] A connecting cylinder 10, fixed to the bottom of the lubrication tank 6, is installed through it. The filter cylinder 711 is threadedly connected to the connecting cylinder 10. An oil drain hole 11 is provided on the side wall of the connecting cylinder 10, and a notch 12 communicating with the oil drain hole 11 is provided at the upper end of the filter cylinder 711. The lubricating oil in the lubrication tank 6 passes through the oil drain hole 11 and the notch 12 in sequence, and finally enters the filter cylinder 711. The debris in the lubricating oil will remain on the top of the filter plate 712. By rotating the filter cylinder 711 until it separates from the connecting cylinder 10, the debris on the filter plate 712 can be cleaned so that the filter plate 712 can perform filtering work normally.

[0034] A blocking component 9 is mounted on the connecting cylinder 10. The blocking component 9 includes a blocking block 91 and a spring 92. The blocking block 91 is slidably disposed inside the connecting cylinder 10, with its bottom abutting against the upper end of the filter cylinder 711. The spring 92 is fixed between the blocking block 91 and the inner top wall of the connecting cylinder 10 and is in a contracted state. As the filter cylinder 711 descends, the spring 92 gradually extends, thereby driving the blocking block 91 connected to the spring 92 to descend. Finally, the blocking block 91 moves to the position corresponding to the oil drain hole 11, thereby reducing the probability of lubricating oil in the lubrication tank 6 overflowing from the oil drain hole 11.

[0035] The adjusting column 733 passes through the connecting rod 724 and is rotatably connected to the connecting rod 724. The rotatable connection between the adjusting column 733 and the connecting rod 724 reduces the friction between the adjusting column 733 and the adjusting groove 8 during movement.

[0036] Multiple grooves are provided on the side wall of the filter cartridge 711. The grooves reduce the probability of slippage when rotating the filter cartridge 711.

[0037] The distance between the top and bottom of the sealing block 91 is greater than the distance between the inner top wall and the inner bottom wall of the oil drain hole 11.

[0038] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
