Description

Technical Field

[0001] The utility model relates to the field of transmission equipment, in particular to a novel transmission rotating torque buffer shaft, which is a device that uses a transmission shaft tube to extrude a telescopic sleeve to increase friction and thereby amplify the torque of the transmission shaft. Background Art

[0002] Take a vehicle as an example. The transmission shaft transmits the power of the engine to the wheels through the clutch, gearbox, transmission shaft, final drive assembly, and axle, causing the wheels to rotate and drive the vehicle's transmission shaft. Damage, wear, deformation, and loss of dynamic balance of the transmission shaft components will cause abnormal noises and vibrations during vehicle driving. In severe cases, it will lead to damage to related components. Moreover, the transmission shaft is a rotating body with high speed and few supports, so its dynamic balance is crucial.

[0003] In the past, the transmission shaft has always been connected in a rigid manner. Therefore, during vehicle driving, gear shifting, or due to road undulations, the transmission shaft will generate inconsistent torque values, resulting in abnormal noise or vibration problems. In addition, when engine power is required, the power of the engine cannot be transmitted in time, leading to insufficient climbing power or insufficient torque when overtaking, resulting in a longer distance and increased risk of danger.

[0004] How to improve the deficiencies of the conventional structure is an issue that relevant industries are actively solving. Summary of the Utility Model

[0005] The main purpose of the utility model is to provide a novel transmission rotating torque buffer shaft, which is a device that uses a transmission shaft tube to extrude a telescopic sleeve to increase friction and thereby amplify the torque of the transmission shaft. Thus, when it is necessary to increase the torque for operation, through the utility model, only the original transmission energy is needed to increase the output torque power.

[0006] The structure of the utility model includes: a shaft tube for transmission, a telescopic sleeve, and a shaft center assembly;

[0007] The shaft tube is tubular. A first spiral transmission part is annularly arranged on the outer side of the shaft tube. A shaft center accommodation groove is arranged in the center of the shaft tube to provide shaft setting for the shaft center assembly;

[0008] The sleeve is joined to the shaft tube. The sleeve is also tubular, and the sleeve has an accommodation space to provide shaft setting for the shaft center assembly. A second spiral transmission part is arranged on the inner side of the sleeve. The aforementioned first spiral transmission part and the second spiral transmission part are meshed with each other, and the sleeve approaches or moves away from the shaft tube according to the rotation direction of the shaft tube;

[0009] The shaft center assembly includes a first shaft rod, a second shaft rod, a first ball bearing, a compression spring, a second ball bearing, and a fixing unit;

[0010] One end of the aforementioned first shaft rod is engaged with a power source. The first shaft rod is axially connected to the axial center accommodating groove of the shaft tube, and the first shaft rod has an external thread portion on one side in the direction of the shaft tube;

[0011] The second shaft rod is arranged at one end of the sleeve. The second shaft rod has an internal thread portion. The external thread portion of the aforementioned first shaft rod is screwed into the internal thread portion of the second shaft rod, so that the first shaft rod is axially engaged with the second shaft rod. The second shaft rod is provided with a fastening thread section at a predetermined position. The second shaft rod is arranged in the accommodating space of the sleeve. The aforementioned first ball bearing, compression spring, second ball bearing, and fixing unit are installed in an axial setting manner. Moreover, the other end of the second shaft rod is axially connected to a spline connecting shaft;

[0012] The aforementioned first ball bearing, compression spring, and second ball bearing are sequentially assembled in the accommodating space of the sleeve, and then the fixing unit is screwed onto the fastening thread section;

[0013] When the power source drives the first shaft rod to rotate in the first direction, the first spiral transmission portion of the shaft tube drives the second spiral transmission portion of the sleeve, so that the sleeve moves in the direction of the shaft tube. The first ball bearing and the second ball bearing in the sleeve compress the compression spring, thereby adjusting and amplifying the output torque of the sleeve; on the contrary, when the power source drives the first shaft rod to rotate in the second direction, the first spiral transmission portion of the shaft tube drives the second spiral transmission portion of the sleeve, so that the sleeve moves away from the shaft tube. The sleeve moves away from the compression spring through the first ball bearing, thereby releasing the elastic force, and can also adjust and amplify the output torque of the sleeve.

[0014] In an embodiment of the present invention, the compression distance of the compression spring is between 0.8 cm and 2.0 cm.

[0015] In an embodiment of the present invention, the spiral angles of the first spiral transmission portion and the second spiral transmission portion are between 42° and 50°.

[0016] In an embodiment of the present invention, a gasket is further sleeved between the second ball bearing and the fixing unit.

[0017] In an embodiment of the present invention, the first spiral transmission portion is an external spiral tooth portion, and the second spiral transmission portion is an internal spiral tooth portion.

[0018] In an embodiment of the present utility model, the first screw drive part is an external thread, the second screw drive part is an internal thread, the sleeve is further provided with an end cap, and the shaft center assembly further includes a coupling bolt, a pressure regulating body and a fine-tuning spring. After the aforementioned coupling bolt passes through the pressure regulating body, the fine-tuning spring, the second ball bearing and the fixing unit, the coupling bolt is screwed to the second shaft rod. The first ball bearing and the compression spring are installed in the accommodating space of the sleeve, and then the shaft center assembly and the shaft tube are installed in the sleeve, thereby forming a buffer shaft structure capable of multiple pressure regulation.

[0020] 1. Through the first screw drive part of the shaft tube and the second screw drive part of the sleeve, the sleeve is pushed and extruded to form the compression action of the compression spring, forming an axial torque buffer zone.

[0021] 2. Through the first screw drive part of the shaft tube and the second screw drive part of the sleeve, the sleeve is pushed and extruded to increase the friction force, thereby amplifying the output torque.

[0022] 3. Through the first screw drive part of the shaft tube and the second screw drive part of the sleeve, the sleeve is pushed and extruded, and the pressure spring can do work in the accommodating space, creating new kinetic energy and storing it in the accommodating space. And continuously store kinetic energy, and when a larger torque is required, it can be instantly released, forming a natural mechanical physical infinite cycle function of kinetic energy storage and kinetic energy release.

[0023] 4. The transmission shaft of the present utility model uses a flexible connection method to replace the conventional transmission shaft transmission method using a rigid connection; the flexible connection transmission can instantly absorb rigid stress and impact force, and then smoothly release the kinetic energy by the flexible connection method.

[0024] 5. The initial power passes through the first screw drive part and the second screw drive part to increase the friction load, and the compression spring stores kinetic energy. The compression spring can instantly release the torque kinetic energy output value, which is 30% higher than the original power in terms of the transmitted torque power.

[0061] As Figures 1 to 3 shown, a novel transmission rotating torque buffer shaft of the utility model comprises: a shaft tube 10 for transmission, a telescopic sleeve 20 and a shaft center assembly 30.

[0062] As Figures 1 to 3 shown, it can be known that the shaft tube 10 is tubular, a first spiral transmission part 11 is arranged on the outer side of the shaft tube 10 in a ring shape, a shaft center accommodating groove 12 is arranged in the center of the shaft tube 10, and the shaft center accommodating groove 12 provides shaft setting for the shaft center assembly 30.

[0063] As Figures 1 to 3 shown, it can be known that the sleeve 20 is joined with the shaft tube 10, the sleeve 20 is also tubular, and the sleeve 20 has an accommodating space 21 to provide shaft setting for the shaft center assembly 30. A second spiral transmission part 22 is arranged on the inner side of the sleeve 20. The foregoing first spiral transmission part 11 and the second spiral transmission part 22 are meshed with each other. The first spiral transmission part 11 is an external spiral tooth part, and the second spiral transmission part 22 is an internal spiral tooth part. By the rotation direction of the shaft tube 10, the sleeve 20 can be close to or far away from the shaft tube 10. In the embodiment of the utility model, the spiral angles of the first spiral transmission part 11 and the second spiral transmission part 22 are between 42° and 50°.

[0064] As Figure 1 、 Figure 3 shown, it can be known that the shaft center assembly 30 comprises a first shaft rod 31, a second shaft rod 32, a first ball bearing 33, a compression spring 34, a second ball bearing 35 and a fixing unit 36.

[0065] As Figure 3As shown, it can be known that one end of the aforementioned first shaft 31 is engaged with a power source (not shown in the figure). The first shaft 31 is pivotally connected to the axial center receiving groove 12 of the shaft tube 10, and the first shaft 31 has an external thread portion 311 on one side in the direction of the shaft tube 10.

[0066] As Figure 1 , Figure 3 shown, it can be known that the second shaft 32 is disposed on the sleeve 20. The second shaft 32 has an internal thread portion 321. The external thread portion 311 of the aforementioned first shaft 31 is screwed into the internal thread portion 321 of the second shaft 32, so that the first shaft 31 and the second shaft 32 are axially engaged. There is a fastening thread section 322 on the second shaft 32. The second shaft 32 is disposed in the accommodating space 21 of the sleeve 20. Furthermore, the other end of the second shaft 32 is axially connected to a spline connecting shaft (not shown in the figure) to transmit power to an output end (such as a wheel). In addition, a gasket 37 can be disposed between the second ball bearing 35 and the fixing unit 36 to increase the contact area between the fixing unit 36 and the second ball bearing 35, so that the compression spring 35 can be compressed smoothly.

[0067] As Figure 1 , Figure 3 shown, it can be known that the aforementioned first ball bearing 33, compression spring 34, and second ball bearing 35 are sequentially assembled in the accommodating space 21 of the sleeve 20. Then, the fixing unit 36 is screwed onto the fastening thread section 322 to position the positions of the aforementioned three components.

[0068] The above is the configuration and introduction of the components of the present invention. Next, the operation mode of the present invention will be introduced.

[0069] As Figure 4 , Figure 5 shown, when the power source drives the first shaft 31 to rotate in the first direction A1, the first spiral transmission portion 11 of the shaft tube 10 drives the second spiral transmission portion 22 of the sleeve 20, so that the sleeve 20 moves in the direction of the shaft tube 10. The first ball bearing 33 and the second ball bearing 35 in the sleeve 20 compress the compression spring 34, thereby adjusting and amplifying the output torque of the sleeve 20. After calculation, the present invention can increase the torque value by about 30%. Therefore, when a vehicle needs to overtake or drive on an uphill section, the present invention can increase the kinetic energy of the wheel (output end) with the original input power, achieving the effect of enhancing power.

[0070] As Figure 6 , Figure 7As shown in the figure, when the power source drives the first shaft 31 to rotate in the second direction A2, the first screw drive portion 11 of the shaft tube 10 drives the second screw drive portion 22 of the sleeve 20, causing the sleeve 20 to move away from the shaft tube 10. The first ball bearing 33 in the sleeve 20 moves away from the compression spring 34, thereby releasing elastic force, and can also adjust and amplify the output torque of the sleeve 20.

[0071] Since the compression distance of the compression spring 34 of the present utility model is between 0.8 cm and 2.0 cm, therefore, the overall structure does not need to be very large to obtain the effect of increasing torque. Therefore, the application fields are wide, such as motorcycles, locomotives, cranes, heavy machinery, generators, trucks, drilling machinery, electric fans, motor rotors, etc., and the structure of the present utility model can be used to achieve the effect of energy saving.

[0072] From the above operation mode, the characteristics of the present utility model are as follows:

[0073] 1. Through the first screw drive portion 11 of the shaft tube 10 and the second screw drive portion 22 of the sleeve 20, the sleeve 20 is pushed and squeezed, forming a compression action of the compression spring 34, and forming an axial torque buffer zone.

[0074] 2. Through the first screw drive portion 11 of the shaft tube 10 and the second screw drive portion 22 of the sleeve 20, the sleeve is pushed and squeezed, increasing the friction force, and thus amplifying the output torque.

[0075] 3. Through the first screw drive portion 11 of the shaft tube 10 and the second screw drive portion 22 of the sleeve 20, the sleeve 20 is pushed and squeezed, and the compression spring 34 can do work in the accommodation space 21, creating new kinetic energy and storing it in the accommodation space 21. And continuously store kinetic energy, and when a larger torque is required, it can be instantly released, forming a natural mechanical physical infinite cycle function of kinetic energy storage and kinetic energy release.

[0076] 4. The transmission shaft of the present utility model uses a flexible connection method to replace the conventional transmission shaft transmission method using a rigid connection; the flexible connection transmission can instantly absorb rigid stress and impact force, and then smoothly release the kinetic energy by the flexible connection method.

[0077] 5. The initial power passes through the first screw drive portion 11 and the second screw drive portion 22 to increase the friction load, and the compression spring 34 stores kinetic energy. The compression spring 34 can instantly release the torque kinetic energy output value, which is 30% higher than the original power in terms of the transmitted torque power.

[0078] 6. Briefly speaking, the working principle of the present utility model is to save energy and improve the output power.

[0079] 7. The structure of the utility model can be used in fields such as fuel vehicles, electric vehicles, generators, lifting machinery, heavy machinery, aircraft, powered ships, elevators, water pumps, drilling machinery, fan motor output, air conditioning compressor rotor output, freight trucks, power tools, etc. As long as there is power to be transmitted, the utility model can be used, greatly improving the economic value of the utility model.

[0080] 8. As Figure 8 , Figure 9 As shown, the first spiral transmission part 11 is an external thread, the second spiral transmission part 22 is an internal thread, the sleeve is further provided with an end cover 23, and the axis assembly 30 further includes a combination bolt 38, a pressure regulating body 39 and a fine-tuning spring 310. After the aforementioned combination bolt 38 penetrates the pressure regulating body 39, the fine-tuning spring 310, the second ball bearing 35 and the fixing unit 36, the combination bolt 38 is screwed on the second shaft 32, the first ball bearing 33 and the compression spring 34 are installed in the accommodating space 21 of the sleeve 20, and then the axis assembly 30 and the shaft tube 10 are installed in the sleeve 20, thereby forming a buffer shaft structure capable of multiple pressure adjustments; Figure 10 As shown, when the first shaft 31 and the second shaft 32 of the shaft assembly 30 are driven to rotate in the direction A1, the first spiral transmission part 11 of the shaft tube 10 will be screwed into the second spiral transmission part 21 of the sleeve 20, and the fine-tuning spring 310 will be compressed by the second ball bearing 35, and the pressure regulating body 39 will generate a secondary adjustment torque on the compression spring 34, and then the power will be output by the end cover 23. On the contrary, when the rotation is opposite to the direction A1, it will return to Figure 9 state, accordingly, by utilizing this embodiment, it is possible to achieve multi-stage adjustment of the torque so that the power can be released smoothly.

[0081] Therefore, the utility model has excellent progress and practicality among similar products. At the same time, after searching domestic and foreign technical data and literature on this type of structure, it is indeed found that there is no identical or similar structure existing before the application of this case. Therefore, this case should have met the patent requirements of "creativity", "suitability for industrial applicability" and "progressiveness", and the application is filed in accordance with the law.

[0082] However, what is described above is only a preferred embodiment of the present utility model.
