Description

Technical Field

[0001] The utility model relates to the technical field of clutches, in particular to a torque measuring tool for a pre-vibration damping assembly of a clutch. Background Art

[0002] The clutch pre-damping assembly is used to transmit torque at idle speed. Figure 1 The partial structure of the clutch is shown in Figure 1. Figure 1 As shown, the pre-damping assembly 100 is arranged on the inner ring of the clutch, including a drive plate, a spring 120 and a cover plate 130 (in Figure 1 (The drive plate is obscured from view by cover plate 130 and is not visible.) The drive plate and cover plate 130 are rotatably connected, leaving a spring cavity. Spring 120 is located in the spring cavity, with its ends connected to the drive plate and cover plate 130, respectively. The drive plate is connected to the clutch assembly, which is connected to the engine (including friction plate 180). Cover plate 130 is connected to the transmission via shaft hole 160. When the engine is idling, torque is transmitted to the drive plate through friction plate 180. Spring 120 compresses to absorb vibration and then transmits torque to cover plate 130 and the transmission.

[0003] The current problem is that the pre-vibration damper assembly 100 needs to be tested for torque transmission performance before use to ensure it can reduce vibration under idle conditions. However, there is currently no tooling to easily and accurately test the torque transmission performance of the pre-vibration damper assembly 100. Testing requires assembling the pre-vibration damper assembly 100 with the clutch body, which is time-consuming and labor-intensive.

[0029] The torque measuring tool provided by the present invention is used to detect the torque transmission performance of the pre-vibration damping assembly of the clutch. Figure 1 As described above, the pre-vibration damping assembly 100 includes a driving plate 110 and a cover plate 130 rotatably coupled to form a spring cavity, and a spring 120 disposed in the spring cavity with its two ends connected to the driving plate 110 and the cover plate 130 .

[0030] Figure 2 The figure shows the three-dimensional structure of the torque measurement tool of the pre-vibration damping assembly 100. Figure 3 The cross-sectional structure at the center position 200a of the torque measurement tool is shown. Figure 4 The cross-sectional structure of the torque measuring tool at the assembly hole position 200b is schematically shown. Figures 1 to 4 As shown, the torque measurement tooling of the pre-vibration damping assembly 100 provided by the present invention includes:

[0031] The clutch assembly contour assembly 210 includes a shaft sleeve 211 extending into the shaft hole 160 of the pre-damping assembly 100 and fixedly connected to the cover plate 130, and a shaft sleeve ring assembly 212 sleeved on the shaft sleeve 211 and fixedly connected to the drive plate 110;

[0032] The torque input plate 220 is fixedly connected to the shaft collar assembly 212;

[0033] The supporting member 230 extends into the shaft sleeve 211 and is fixedly connected to the shaft sleeve 211 .

[0034] The torque measurement tool for the pre-vibration damper assembly 100 provided by the present invention uses a clutch assembly profiling assembly 210 to simulate key components of the clutch assembly that mate with the pre-vibration damper assembly 100, thereby simulating the actual assembly environment of the pre-vibration damper assembly 100 and ensuring accurate and reliable testing of the torque transmission performance of the pre-vibration damper assembly 100. The clutch assembly profiling assembly 210 includes a sleeve 211 fixedly connected to the cover plate 130 and a sleeve ring assembly 212 fixedly connected to the drive plate 110, respectively simulating the sleeve components that mate with the cover plate 130 and the sleeve ring components that mate with the drive plate 110 in the clutch assembly under actual assembly conditions.

[0035] The torque measurement fixture of the present invention also securely supports the pre-vibration damper assembly 100 and its mating components via a support member 230, and utilizes a torque input plate 220 fixedly connected to the shaft collar assembly 212 for torque input. During testing, torque is transmitted to the drive plate 110 via the shaft collar assembly 212. Driven by the drive plate 110, the spring 120 compresses to absorb vibration and then transmits the torque to the cover plate 130. By measuring the force applied to the cover plate 130 and analyzing it in conjunction with the input torque, the pre-vibration damper performance and torque transfer capacity of the spring 120 can be effectively tested, thereby deriving the torque transfer performance of the pre-vibration damper assembly 100.

[0036] By adopting the torque measuring tool of the present invention, the torque transmission performance of the pre-vibration damping assembly 100 can be easily and accurately detected, thereby ensuring that the pre-vibration damping assembly 100 put into use meets the performance requirements of effectively absorbing vibration and improving stability under idle conditions.

[0037] In some embodiments, the torque input plate 220, the shaft collar assembly 212, and the drive disc 110 are provided with relatively positioned assembly holes, and the torque input plate 220, the shaft collar assembly 212, and the drive disc 110 are fixedly connected by fasteners 240 passing through the assembly holes. The fasteners 240 are suitable components such as bolts and rivets that can conveniently and securely connect the torque input plate 220, the shaft collar assembly 212, and the drive disc 110.

[0038] In addition, the support member 230, the sleeve 211 and the cover plate 130 may also be riveted or fastened together by fasteners such as bolts.

[0039] In some embodiments, the shaft collar assembly 212 includes: at least one first shaft collar 212a, which is pressed against the drive disc 110; and a second shaft collar 212b, which is pressed against the at least one first shaft collar 212a. The first shaft collar 212a and the second shaft collar 212b have different thicknesses and / or different materials. The different thicknesses and materials of the first and second shaft collars 212a, 212b, not only simulate the actual assembly environment of the pre-vibration damper assembly 100, but also reliably press the drive disc 110, ensuring lossless torque transmission to the drive disc 110 during testing, thereby ensuring accurate testing of the torque transmission performance of the pre-vibration damper assembly 100.

[0040] There may be two or more first shaft collars 212 a , which may be determined according to the actual assembly environment of the pre-vibration damping assembly 100 .

[0041] In some embodiments, the shaft collar assembly 212 further includes a washer 121c compressed between the second shaft collar 212b and at least one first shaft collar 212a. The washer 121c can increase friction, ensuring a secure fit between the second shaft collar 212b and the first shaft collar 212a, thereby stably transmitting torque.

[0042] In some embodiments, the torque measurement tool further includes: a first pad 251 pressed between the shaft collar assembly 212 and the driving disk 110 ; and a second pad 252 pressed between the torque input plate 220 and the shaft collar assembly 212 .

[0043] The first gasket 251 can fill the gap between the shaft collar assembly 212 and the drive disk 110, so that the shaft collar assembly 212 and the drive disk 110 are pressed tightly and fit firmly; the second gasket 252 can fill the gap between the torque input plate 220 and the shaft collar assembly 212, so that the torque input plate 220 and the shaft collar assembly 212 are pressed tightly and fit firmly.

[0044] In some embodiments, a torque input hole 222 is provided at the center of the torque input plate 220 , and the torque input hole 222 is used to connect a torque input shaft.

[0045] During the test, the test torque is input through the torque input axial torque measurement tool, and the torque transmission performance of the pre-vibration damping assembly 100 can be obtained based on the input test torque and the detected force on the cover plate 130.

[0046] In some embodiments, the support member 230 includes a support rod 231 extending into the sleeve 211 and a support seat 232 connected to the support rod 231. The support seat 232 is used to be installed on the test bench. The support rod 231 is fixedly connected to the sleeve 211. The support rod 231 and the sleeve 211 together support the pre-vibration damping assembly 100 and the sleeve ring assembly 212 and other components.

[0047] In summary, the torque measurement fixture of the present invention, through the coordination of the clutch assembly contour assembly 210 and the support member 230 with the pre-vibration damper assembly 100, simulates the actual assembly environment of the pre-vibration damper assembly 100 and stably supports the pre-vibration damper assembly 100, enabling accurate and reliable testing of the torque transmission performance of the pre-vibration damper assembly 100. During testing, torque is input from the torque input plate 220 and transmitted to the drive plate 110 via the shaft collar assembly 212. Driven by the drive plate 110, the spring 120 compresses to absorb vibration and then transmits the torque to the cover plate 130. By measuring the force applied to the cover plate 130 and analyzing it in combination with the input torque, the pre-vibration damper performance and torque transmission capacity of the spring 120 can be effectively tested, thereby determining the torque transmission performance of the pre-vibration damper assembly 100.

[0048] By adopting the torque measuring tool of the present invention, the torque transmission performance of the pre-vibration damping assembly 100 can be easily and accurately detected, ensuring that the pre-vibration damping assembly 100 put into use meets the performance requirements of effectively absorbing vibration and improving stability under idle conditions.
