Description

Technical Field

[0001] This invention relates to the field of transmission shaft testing technology, and in particular to a high-torque carbon fiber transmission shaft testing platform. Background Technology

[0002] Carbon fiber driveshafts, with their advantages of high specific strength, high specific modulus, good fatigue resistance, and lightweight design, are widely used in high-torque transmission systems in new energy commercial vehicles, heavy engineering machinery, and high-end rail transit equipment. Especially ultra-long carbon fiber driveshafts (length-to-diameter ratio greater than 20) can effectively reduce the number of connection points in the transmission system, improve power transmission efficiency, and have become a core component for lightweight upgrades of transmission systems in large equipment. Traditional driveshaft torque testing often uses end-loading methods, where the torque loading mechanism of the testing platform is directly connected to both ends of the driveshaft via a coupling to apply and detect torque. However, when this loading method is applied to ultra-long carbon fiber driveshafts, the excessively large length-to-diameter ratio leads to significant torque attenuation along the shaft during end-loading, resulting in uneven torque distribution and severe stress concentration in the end area. This not only affects the accuracy of torque detection data but may also cause damage such as carbon fiber delamination and resin matrix cracking at the driveshaft end, failing to accurately reflect the actual load-bearing capacity of the driveshaft. Summary of the Invention

[0008] As a preferred embodiment of the present invention, a cooling assembly is provided on the outer surface of the compression belt. The cooling assembly includes a water pump fixedly installed on the top of the movable plate. A cooling plate filled with cooling water is provided on the outer surface of the compression belt, and a drying layer is provided on the surface of the cooling plate near the compression belt. The output end of the water pump is connected to the interior of the cooling plate through a first connecting pipe.

[0009] As a preferred embodiment of the present invention, a water tank is fixedly installed at the top of the movable plate, a return pipe is installed on the outer surface of the pressing belt, and one end of the return pipe is connected to the inside of the water tank through a second connecting pipe.

[0010] As a preferred embodiment of the present invention, a pressurizing component is provided at the top of the movable plate. The pressurizing component includes a cylinder fixedly installed at the top of the movable plate. A sliding rod slides through the inside of the cylinder.

[0012] As a preferred embodiment of the present invention, the cleaning roller is fixedly installed with absorbent cotton, and the absorbent cotton is provided with a water storage pipe, which is connected to the water outlet pipe.

[0013] As a preferred embodiment of the present invention, a main detection platform is provided on the side of the base plate, and the main detection platform is electrically connected to multiple detection blocks through a built-in power supply.

[0014] Compared with the prior art, the beneficial effects of the present invention are: This invention utilizes the frictional transmission between the clamping belt of the torque transmission component and the drive shaft body, along with the partition on the belt surface to achieve segmented loading. This effectively solves the problem of uneven torque distribution at the ends of ultra-long carbon fiber drive shafts due to their large length-to-diameter ratio. Furthermore, the groove design of the partition is designed to allow for thermal expansion gaps, further ensuring the uniformity of contact pressure under different torque conditions. This avoids damage such as carbon fiber layer delamination and resin cracking at the drive shaft ends, ensuring that the test data accurately reflects the actual load-bearing capacity of the shaft.

[0015] This invention utilizes multiple stacked support springs in conjunction with a pressure plate to form an adaptive damping support structure. This structure can flexibly counteract the deflection deformation caused by the weight of an ultra-long drive shaft. Simultaneously, the elastic properties of the belt can buffer the instantaneous impact torque during motor drive, reducing torsional and bending vibrations of the shaft. Furthermore, the detection block connected by the elastic rope can move synchronously with the slight deformation of the shaft, avoiding interference from rigid contact with the detection signal. This significantly improves the stability of the torque detection process and the accuracy of data acquisition.

[0016] This invention uses a cooling plate and a water circulation system to cool the compression belt in real time, and a drying layer to prevent the belt from getting damp and slipping, thus delaying belt aging. At the same time, the cleaning rollers of the cleaning component spray cleaning media through air holes, and combined with carbon ball filtration and water-absorbing cotton, can remove friction debris from the belt surface in a timely manner, preventing debris from entering the transmission contact surface and affecting torque transmission efficiency.

[0017] This invention utilizes a pressurization component to drive a sliding rod and limit rollers to rise and fall using cooling water pressure. The belt tension can be dynamically adjusted according to the required detection torque, balancing the sensitivity of low-torque detection with the transmission reliability of high-torque detection. Meanwhile, the movable plate can flexibly adjust the position of the support component and the torque transmission component. With multiple sets of mounting side plates, it can adapt to the detection of ultra-long carbon fiber drive shafts of different lengths and diameters. The stacked design of the support springs can adjust the support stiffness by increasing or decreasing the number of auxiliary springs, further improving the adaptability to working conditions.

[0018] This invention enables modular installation and testing of ultra-long carbon fiber drive shafts through a movable plate, simplifying the overall structure of the testing station. At the same time, the main testing station is electrically connected to multiple testing blocks, allowing for simultaneous acquisition of testing data from multiple locations without the need for manual point-by-point measurement, thus significantly improving testing efficiency.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figure 1-8 This invention provides a high-torque carbon fiber drive shaft testing platform, including a base plate 2, a plurality of mounting side plates 4 at the top of the base plate 2, a drive shaft body 3 at the top of the mounting side plates 4, a stabilizing mechanism 5 at the top of the base plate 2, the stabilizing mechanism 5 including a movable plate 55 mounted at the top of the base plate 2, a support assembly 51 at the top of the movable plate 55, a support spring 517 fixedly mounted at the top of the movable plate 55, a long plate 511 at the top of the support spring 517, a plurality of elastic ropes 512 fixedly mounted on the surface of the long plate 511 near the drive shaft body 3, and a detection block 513 at the free end of the elastic ropes 512, a torque transmission assembly 52 at the top of the movable plate 55, the torque transmission assembly 52 including a roller 524 rotatably mounted at the top of the movable plate 55, a motor 522 fixedly mounted at the top of the movable plate 55, and the output shaft of the motor 522 fixedly connected to the roller 524, and a pressure belt 523 is installed between the roller 524 and the drive shaft body 3 for transmission.

[0023] The movable plate 55 can be moved and adjusted on the base plate 2. The support spring 517 of the support component 51 provides elastic support. The long plate 511 approaches the drive shaft body 3 under the action of the support spring 517. The detection block 513 connected by the elastic rope 512 contacts the drive shaft body 3 to detect relevant parameters. At the same time, the motor 522 drives the roller 524 to rotate and transmits torque to the drive shaft body 3 through the tightening belt 523 to realize torque transmission for detection. Through the stabilizing mechanism 5 and the torque transmission component 52, the torque transmission and detection of the drive shaft body 3 can be stably performed, providing basic support and power transmission functions for detection and ensuring the accurate operation of the detection process.

[0024] In some embodiments, an oil plate 516 is fixedly installed at one end of the support spring 517 near the drive shaft body 3, and a clamping plate 514 is fixedly installed on the side wall of the oil plate 516. The long plate 511 is connected to the clamping plate 514 by screws. The support spring 517 is composed of multiple sets of auxiliary springs stacked together, and a pressure plate is fixedly installed between each pair of auxiliary springs.

[0025] Among them, the oil plate 516 at one end of the support spring 517 is connected to the long plate 511 with screws through the clamping plate 514, which facilitates disassembly and adjustment of the spacing. The support spring 517 adopts multiple sets of auxiliary springs stacked together, and the pressure plate increases the pressure between the auxiliary springs. The elasticity of the support spring 517 can be adjusted according to different needs, so that the support assembly 51 provides more stable and flexible support for the long plate 511 and the detection block 513, and is suitable for the detection of different specifications of the drive shaft body 3.

[0026] In some embodiments, a top plate 515 is fixedly installed on the surface of the oil plate 516 near the drive shaft body 3, and the cross section of the top plate 515 is arc-shaped. The interior of the oil plate 516 is filled with lubricating oil, and an oil-absorbing cotton 518 for absorbing lubricating oil is provided in the middle of the top plate 515.

[0027] Among them, the arc-shaped top plate 515 of the oil plate 516, which is close to the transmission shaft body 3, contacts the surface of the transmission shaft body 3, which can increase the contact fit with the transmission shaft body 3. The lubricating oil inside the oil plate 516 is absorbed by the oil-absorbing cotton 518 and slowly released to the contact surface between the top plate 515 and the transmission shaft body 3, which can reduce the friction between the top plate 515 and the transmission shaft body 3, reduce wear, and ensure a long-lasting and stable lubrication effect.

[0028] In some embodiments, a partition 521 is fixedly installed on the surface of the compression belt 523 near the drive shaft body 3, and both outer surfaces of the partition 521 are provided with a plurality of grooves for reserving thermal expansion gaps.

[0029] Among them, the partition plate 521 on the surface of the pressure belt 523 contacts the drive shaft body 3. The groove on the partition plate 521 provides a thermal expansion gap when the pressure belt 523 is heated and expands, preventing the pressure belt 523 from being damaged or affecting the torque transmission effect due to excessive stress caused by thermal expansion and contraction. At the same time, it ensures the stability of the friction between the pressure belt 523 and the drive shaft body 3, and improves the accuracy and reliability of torque transmission.

[0030] In some embodiments, a cooling assembly 53 is provided on the outer surface of the compression belt 523. The cooling assembly 53 includes a water pump 531 fixedly installed on the top of the movable plate 55. A cooling plate 533 filled with cooling water is provided on the outer surface of the compression belt 523, and a drying layer is provided on the surface of the cooling plate 533 near the compression belt 523. The output end of the water pump 531 is connected to the interior of the cooling plate 533 through a first connecting pipe 532.

[0031] The water pump 531 delivers cooling water from the water tank 537 to the cooling plate 533 through the first connecting pipe 532. The cooling plate 533 can promptly remove the heat generated by the clamping belt 523 during torque transmission, reduce the temperature of the clamping belt 523, prevent the performance of the clamping belt 523 from deteriorating due to excessive temperature, ensure the stability and accuracy of torque transmission, and improve detection accuracy. The drying layer prevents cooling water vapor from leaking onto the surface of the clamping belt 523, affecting the use of the clamping belt 523.

[0032] In some embodiments, a water tank 537 is fixedly installed on the top of the movable plate 55, a return pipe 534 is connected to the outer surface of the clamping belt 523, one end of the return pipe 534 is connected to the inside of the water tank 537 through a second connecting pipe 536, the bottom end of the water tank 537 is connected to the input end of the water pump 531 through a water inlet pipe 535, and a filter component for filtering water source is provided inside the water tank 537.

[0033] The cooling water in the cooling plate 533 flows back to the water tank 537 through the return pipe 534 and the second connecting pipe 536. The filter component in the water tank 537 filters and purifies the return water. The purified water enters the water pump 531 through the inlet pipe 535 to realize the recycling of cooling water. The filter component removes impurities from the cooling water to prevent impurities from clogging the pipes or wearing the water pump 531, ensuring the stable operation of the water circulation system and guaranteeing the continuous and reliable cooling effect.

[0034] In some embodiments, a pressure boosting assembly 54 is provided at the top of the movable plate 55. The pressure boosting assembly 54 includes a cylinder 541 fixedly installed at the top of the movable plate 55. A slide rod 542 slides through the inside of the cylinder 541. The bottom end of the cylinder 541 is connected to the first connecting pipe 532. A fixing plate 543 is fixedly installed at the top of the slide rod 542. Two limiting rollers 545 for pressurizing the belt 523 are rotatably installed at the top of the fixing plate 543, and the pressing belt 523 slides through the two limiting rollers 545.

[0035] The water pump 531 delivers cooling water to the cylinder 541. The water pressure inside the cylinder 541 pushes the slide bar 542 to slide upward. The slide bar 542 drives the fixed plate 543 to rise. The limiting roller 545 on the fixed plate 543 pressurizes the clamping belt 523, increasing the friction between the clamping belt 523 and the drive shaft body 3, thereby adjusting the torque transmission efficiency, making the torque transmission more accurate, adapting to different testing conditions and torque requirements, and improving the flexibility and accuracy of testing.

[0036] In some embodiments, a cleaning component 546 is rotatably mounted on the top of the fixed plate 543. The cleaning component 546 includes a cleaning roller 5461 rotatably mounted on the top of the fixed plate 543. The interior of the cleaning roller 5461 is connected to the interior of the cylinder 541 through a water outlet pipe 544, and a plurality of air holes 5462 for cleaning are provided on the outer surface of the cleaning roller 5461.

[0037] Cooling water inside cylinder 541 enters the cleaning roller 5461 through water outlet pipe 544. Water-absorbing cotton 5465 absorbs the water entering the cleaning roller 5461. When the cleaning roller 5461 rotates, the water is squeezed out through air hole 5462 to clean the pressure belt 523. The cleaning component 546 cleans the pressure belt 523 while the pressurizing component 54 is working, removing dirt and impurities from the surface of the pressure belt 523, ensuring stable friction between the pressure belt 523 and the drive shaft body 3, and improving torque transmission effect.

[0038] In some embodiments, a water-absorbing cotton 5465 is fixedly installed inside the cleaning roller 5461, and a water storage pipe 5466 is provided inside the water-absorbing cotton 5465. The water storage pipe 5466 is connected to the water outlet pipe 544. A breathable membrane 5464 is provided between the inner wall of the cleaning roller 5461 and the water-absorbing cotton 5465, and a plurality of carbon balls 5463 are provided inside the air holes 5462.

[0039] The absorbent cotton 5465 absorbs water from the water storage tube 5466, and the breathable membrane 5464 controls the rate of water release, allowing water to be squeezed out evenly and slowly from the air holes 5462. The carbon balls 5463 in the air holes 5462 can further filter and regulate the water, making the cleaning process more uniform and effective. This allows for better removal of stubborn stains from the surface of the pressure belt 523, while also preventing excessive water from damaging the pressure belt 523, thus improving cleaning quality and efficiency.

[0040] In some embodiments, a main detection stage 1 is provided on the side of the base plate 2, and the main detection stage 1 is electrically connected to multiple detection blocks 513 through a built-in power supply.

[0041] The main testing station 1 supplies power to multiple testing blocks 513 via a built-in power supply. The testing blocks 513 contact the drive shaft body 3, detect various parameters of the drive shaft body 3 during torque transmission, and transmit the data to the main testing station 1 for analysis and processing. This provides reliable data support for evaluating the quality and performance of the drive shaft body 3 and facilitates the timely detection of problems in the drive shaft body 3.

[0042] Working Principle: The base plate 2, through multiple mounting side plates 4, provides basic support and positioning for the drive shaft body 3, ensuring that the drive shaft body 3 is in a preset testing posture. For ultra-long carbon fiber drive shafts, this testing platform transmits torque through the friction between the belt and the shaft, achieving segmented or multi-point loading, making the torque distribution along the shaft more uniform and avoiding stress concentration at the ends. Specifically, the moving plate 55 moves and adjusts its position on the base plate 2, the support spring 517 of the support assembly 51 provides elastic support, and the long plate 511 approaches the drive shaft body 3 under the action of the support spring 517. The testing block 513, connected by the elastic rope 512, contacts the drive shaft body 3 to detect relevant parameters. Simultaneously, the motor 522 drives the roller 524 to rotate, transmitting torque to the drive shaft body 3 through the tightening belt 523, thus achieving torque transmission for testing. Through the stabilizing mechanism 5 and the torque transmission assembly 52, torque transmission and testing of the drive shaft body 3 can be stably performed, providing basic support and power transmission functions for testing, ensuring accurate operation of the testing process.

Any simple changes, equivalent substitutions, or modifications made based on the present invention to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of the present invention.
