Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0030] It should be noted that, unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0031] In related technologies, the clutch disengagement clearance value is one of the important functional parameters of the clutch. Conventionally, the disengagement clearance value is measured manually; however, manual measurement is inefficient, prone to error, and unsuitable for mass production. Therefore, there is a need to design a device that is efficient, has low error, and is convenient to use.

[0032] To improve the measurement efficiency of the separation gap value and reduce measurement errors, this application provides an automotive single-clutch separation gap detection device and system. The device includes a reference pressure rod with at least two displacement sensors mounted on it, each of which contacts an elastic plate disposed in the component to be tested. An inflatable positioning seat is used to cooperate with the reference pressure rod to fix the component to be tested and to push the elastic plate in a first direction by inflation. A pressure plate is disposed on the elastic plate when the component to be tested is fixed, and the pressure plate is used to push the elastic plate in a second direction, the opposite of the first direction. The pressure plate and the inflatable positioning seat allow the elastic plate in the component to be tested to quickly and easily reach the engagement and disengagement limits of the clutch, thereby reducing the difficulty of measurement operations and improving measurement efficiency. Furthermore, by measuring the displacement distance of the elastic plate as it quickly reaches the engagement and disengagement limits of the clutch using the displacement sensors, the separation gap value can be obtained more accurately, effectively reducing measurement errors.

[0033] See Figures 1 to 2 In this embodiment of the application, an automotive single clutch separation gap detection device is provided. The device may include a reference pressure rod 1, an air-filled positioning seat 2, and a pressure plate 3.

[0034] The reference pressure rod 1 is equipped with at least two displacement sensors 11, each of which contacts an elastic plate disposed in the workpiece 100. The inflatable positioning seat 2 can be used to fix the workpiece 100 in cooperation with the reference pressure rod 1, and to push the elastic plate in a first direction by inflation. The pressure plate 3 is disposed on the elastic plate when the workpiece 100 is fixed, and can be used to push the elastic plate in a second direction, which is the opposite of the first direction.

[0035] In one embodiment, the first direction refers to the direction from the inflatable positioning seat 2 to the test piece 100.

[0036] Specifically, during test preparation, the test piece 100 is placed on the inflatable positioning seat 2. The reference pressure rod 1 is pressed against the test piece 100 by pushing it (e.g., using an inflatable press). Then, the pressure plate 3 is pressed against the elastic plate in the test piece 100 by pushing it (e.g., using an inflatable press). The pressure plate 3 is pushed in a second direction to compress the elastic plate in the second direction until the first stop point. Simultaneously, multiple displacement sensors 11 collect displacement parameters during compression in the second direction. Then, the pushing of the pressure plate 3 is stopped, and the inflatable positioning seat 2 is inflated to push the elastic plate in the first direction until the second stop point. Simultaneously, multiple displacement sensors 11 collect displacement parameters during rebound in the first direction. Finally, the test result is determined by the displacement parameters during compression in the second direction and the displacement parameters during rebound in the first direction.

[0037] In one embodiment, the reference pressure bar 1 may include a first plate-like structure 12 and a plurality of sensor mounting structures 13. The plurality of sensor mounting structures 13 are disposed at the edge of the first plate-like structure 12 and extend in a second direction. The number of sensor mounting structures 13 is the same as the number of displacement sensors 11, and each sensor mounting structure 13 is used to mount one of the plurality of displacement sensors 11. The first plate-like structure 12 may be cylindrical, polygonal, etc., and is not specifically limited here. Furthermore, the sensor mounting structures 13 may be sheet-like structures, columnar structures, etc., extending in the second direction, and are not specifically limited here.

[0039] In one embodiment, the rod structure 14 is arranged in a columnar shape, and the multiple sensor mounting structures 13 are distributed based on adjacent angles of the column center of the rod structure 14. For example, when the number of displacement sensors 11 is 3, the included angle between each displacement sensor 11 and its adjacent displacement sensor 11 is 120°; when the number of displacement sensors 11 is 4, the included angle between each displacement sensor 11 and its adjacent displacement sensor 11 is 90°.

[0040] In one embodiment, the pressure plate 3 may include a second plate-like structure 31, which has the same number of notch structures 32 as the displacement sensors 11. The distribution positions of the multiple notch structures 32 correspond to the distribution positions of the multiple displacement sensors 11. Specifically, each displacement sensor 11 corresponds to one of the multiple notch structures 32, and each displacement sensor 11 contacts the elastic plate through the notch structure 32 corresponding to itself.

[0041] In one embodiment, the pressure plate 3 may further include a contact structure 33, which is disposed at the edge of the second plate-like structure 31 and extends in a second direction. The contact structure 33 can be used to contact the elastic plate. The contact structure 33 can be a single integral structure or multiple structures (see [reference]). Figure 1 (in the form of), no specific form is specified here.

[0042] In one embodiment, the number of contact structures 33 is the same as the number of displacement sensors 11, and the multiple contact structures 33 are distributed based on adjacent corners such as the center of the rod structure 14.

[0043] In one embodiment, the test piece 100 includes a drive shaft 110, and the inflatable positioning seat 2 may include a drive shaft receiving structure 21. The drive shaft receiving structure 21 can be used to receive and fix the drive shaft 110 when the test piece 100 is placed on the inflatable positioning seat 2.

[0044] In one embodiment, the elastic plate is an inherent component of the test piece 100. During testing, the pressure plate 3 and the displacement sensor 11 are directly brought into contact with the inherent component of the test piece 100, which is the elastic plate.

[0045] In one embodiment, the test piece 100 does not include an elastic plate; the device may further include an elastic reference plate 4, which contacts each displacement sensor 11 and serves as an elastic plate. The elastic reference plate 4 may be disposed inside or on top of the test piece 100, or in the middle or bottom of the outer casing of the test piece 100, etc., and is not specifically limited here.
