Description

Technical Field

[0001] This invention belongs to the field of automotive clutch technology, specifically relating to a clutch parallelism detection device. Background Technology

[0002] The clutch is located inside the flywheel housing between the engine and the transmission. The clutch assembly is fixed to the rear surface of the flywheel with screws. The output shaft of the clutch is the input shaft of the transmission. During vehicle operation, the driver can depress or release the clutch pedal as needed to temporarily separate and gradually engage the engine and transmission, thereby cutting off or transmitting power from the engine to the transmission.

[0003] An automotive clutch mainly consists of a driving part, a driven part, a pressing part, and an operating part. The driven part consists of a driven disc, friction plates, and a driven shaft. The friction plates are used for friction transmission. After the friction plates are manufactured, a parallelism testing device is needed to test the parallelism of the friction disc.

[0004] However, sliding the pointer of the indicator on the surface of the friction plate will cause the pointer to rub against the surface of the friction plate, resulting in damage to the pointer. In addition, the accuracy of the indicator is not good, and it cannot accurately detect the parallelism of the friction plate. Summary of the Invention

[0022] 3. Beneficial effects

[0023] The technical solution provided by this invention has the following advantages compared with the prior art:

[0024] This invention uses a rotating infrared emitter and receiver to detect the parallelism of the friction plates inside the clutch from multiple angles. The infrared emitter emits infrared light that comes into contact with the surface of the friction plates. When the surface of the friction plates is uneven, it will block the infrared receiver from receiving the infrared light, thus detecting the parallelism of the friction plate surface.

[0025] A pressure plate is set on the top of the testing device. The friction plate is placed into the friction plate lifting structure. Then, the motor drives the friction plate to rotate, so that the friction plate contacts the pressure plate and rubs against the bottom of the pressure plate. Then, the parallelism is tested to detect that the friction plate is subjected to non-uniform force. Four screws drive the friction plate lifting structure to lift and lower to maintain the stability and levelness of the friction plate. Attached Figure Description

[0038] Reference Figure 1-6 The clutch parallelism detection device shown includes a mounting plate 1, an infrared receiving structure 3 is provided on one side of the top of the mounting plate 1, and an infrared emitting structure 11 is provided on the other side of the top of the mounting plate 1.

[0039] The infrared receiving structure 3 includes a drive shaft 301, a driven gear 302 at the bottom of the drive shaft 301, a slider 303 at one end of the drive shaft 301, the slider 303 being slidably connected to the inside of the mounting plate 1, and an infrared receiver 304 being rotatably connected to the other end of the drive shaft 301.

[0040] The infrared emitting structure 11 includes a positioning strip 1101, which is disposed on the top of the mounting plate 1. An auxiliary groove 1102 is formed on the inner wall of the positioning strip 1101. A spring rod 1103 is disposed on the inner wall of the auxiliary groove 1102. A lifting block 1104 is disposed at one end of the spring rod 1103. The lifting block 1104 is slidably connected to the inside of the auxiliary groove 1102. An infrared emitter 1110 is disposed on the top of the lifting block 1104. The infrared emitter 1110 is aligned with the infrared receiver 304. A rotating structure is disposed at the bottom of the lifting block 1104.

[0041] Furthermore, in the above technical solution, the mounting plate 1 has two sliding grooves 2 on its top. A gear body 4 is provided on the top of the mounting plate 1 near the sliding groove 2. The slider 303 is slidably connected to the inside of the sliding groove 2. The driven gear 302 on the top of the slider 303 meshes with the gear body 4. A linear motor is provided at the bottom of the slider 303. The linear motor drives the slider 303 to slide on the inner wall of the sliding groove 2. The slider 303 drives the semi-circular driven gear 302 to mesh with the gear body 4 through the transmission shaft 301, so that the transmission shaft 301 drives the infrared receiver 304 to rotate, so that the infrared receiver 304 is always aligned with the infrared transmitter 1110 and receives the signal from the infrared transmitter 1110.

[0042] Furthermore, in the above technical solution, the four sides of the bottom of the mounting plate 1 are rotatably connected to a transmission screw 8, and a moving block 9 is provided on the outer wall of the transmission screw 8. The bottom of the mounting plate 1 is rotatably connected to an active bevel gear 7, and a drive motor 12 is provided at the bottom of the mounting plate 1. A rotating gear 13 is provided at the output end of the drive motor 12. The rotating gear 13 meshes with the inner side of the active bevel gear 7. The drive motor 12 drives the active bevel gear 7 to rotate through the rotating gear 13. The active bevel gear 7 drives the transmission screw 8 to rotate through the bevel gear provided at one end of the transmission screw 8. The transmission screw 8 drives the friction plate lifting structure 10 and the friction plate fixed inside to lift and lower through the moving block 9. The transmission screw 8 provided on the four sides can remain stable during the lifting and lowering of the friction plate lifting structure 10, and can stably keep the friction plate fixed inside the friction plate lifting structure 10 parallel to the mounting plate 1.

[0043] Furthermore, in the above technical solution, a servo motor 5 is provided on the top of the mounting plate 1, and a pressure plate 6 is provided at the output end of the servo motor 5. The pressure plate 6 is located directly above the mounting plate 1. The servo motor 5 drives the pressure plate 6 to rotate, and then the pressure plate 6 rubs the surface of the friction pad. Then, a second parallelism test is performed to check whether the friction pad can be evenly stressed.

[0044] Furthermore, in the above technical solution, a friction plate lifting structure 10 is provided in the middle of the mounting plate 1. The friction plate lifting structure 10 includes a lifting shaft 1001, a fixed shaft 1002 is provided at the top of the lifting shaft 1001, and a fixed plate 1003 is provided at the bottom of the lifting shaft 1001. A connecting rod 1004 is rotatably connected to the outer wall of the fixed plate 1003. One end of the connecting rod 1004 is rotatably connected to the moving block 9. The moving block 9 pulls the connecting rod 1004 to rotate, and then the connecting rod 1004 drives the fixed plate 1003 to move upward. The fixed plate 1003 drives the fixed shaft 1002 to move upward through the lifting shaft 1001, so that the fixed shaft 1002 drives the brake pad to move upward and keep it parallel to the infrared receiver 304 and the infrared transmitter 1110.

[0045] Furthermore, in the above technical solution, the rotating structure includes a rotating rod 1105, which is rotatably connected to the bottom of the lifting block 1104. A planar spiral spring is provided between the rotating rod 1105 and the lifting block 1104. An auxiliary shaft 1106 is rotatably connected to one end of the rotating rod 1105. A sliding shaft 1107 is provided on the inner wall of the auxiliary shaft 1106. The bottom of the friction plate is in contact with the top of the sliding shaft 1107. When the friction plate moves upward, the planar spiral spring drives the rotating rod 1105 to rotate. Then, the rotating rod 1105 drives the roller 1108 to move upward and contact the bottom of the friction plate. At the same time, when the rotating rod 1105 rotates to the maximum angle, it separates from the friction plate. When the friction plate descends, it contacts the roller 1108 again and pushes the rotating rod 1105 to rotate to support the friction plate.

[0046] Furthermore, in the above technical solution, a roller 1108 is rotatably connected to the top of the sliding shaft 1107, and a load block 1109 is provided at the bottom of the sliding shaft 1107. The load block 1109 drives the auxiliary shaft 1106 to rotate through the sliding shaft 1107 according to gravity, so that the roller 1108 always remains horizontal. A motor is provided at the bottom of the infrared transmitter 1110 for driving the infrared transmitter 1110.

[0047] A clutch parallelism detection device, characterized in that:

[0048] S1, the friction plate is engaged with the fixed shaft 1002, the bottom of the friction plate is in contact with the top of the roller 1108, and the friction plate lifting structure 10 drives the friction plate to move downward, so that the infrared transmitter 1110 and the infrared receiver 304 are in the same cross section as the friction plate.

[0049] S2, the infrared transmitter 1110 and the infrared receiver 304 rotate, and the infrared transmitter 1110 and the infrared receiver 304 always remain aligned. When the infrared light emitted by the positioning strip 1101 is blocked by the friction plate and the infrared receiver 304 cannot receive the infrared light, the parallelism of the friction plate is unqualified, otherwise it is qualified.

[0050] S3, the friction plate lifting structure 10 drives the friction plate to fit against the pressure plate 6, the pressure plate 6 rubs against the friction plate lifting structure 10, and then the friction plate lifting structure 10 drives the friction plate to descend. Following the steps of S2, the parallelism of the friction plate is checked again to see if the friction plate can be evenly stressed during use.

[0051] Working principle of this invention:

[0052] Refer to the instruction manual appendix Figure 1-6 First, when it is necessary to test the parallelism of the brake pads inside the clutch, the middle of the brake pads is connected to the fixed shaft 1002. Then, the bottom of the four sides of the brake pads are in contact with the top of the roller 1108. After that, the drive motor 12 is started. The drive motor 12 drives the rotating gear 13 to rotate. The rotating gear 13 drives the active bevel gear 7 to rotate. The active bevel gear 7 drives the transmission screw 8 to rotate through the bevel teeth at one end of the transmission screw 8. The transmission screw 8 drives the moving block 9 to move inward, so that the moving block 9 drives the lifting shaft 1001 to move downward through the connecting rod 1004. Then, the lifting shaft 1001 drives the brake pads to move downward and squeeze the roller 1108. Then, the roller 1108 drives the rotating rod 1105 to rotate and squeeze the planar spiral spring, so that the infrared transmitter 1110 and the infrared receiver 304 are aligned with the top of the friction plate.

[0053] Then, the infrared emitter 1110 emits infrared light, which moves on the surface of the friction pad. When blocked by the friction pad, the infrared receiver 304 cannot receive or receives only a small amount of infrared light. The principle is similar to that of a photoelectric switch. The parallelism of the brake pad is detected by sensing the infrared light to start or stop. At the same time, the linear motor drives the slider 303 to slide on the inner wall of the groove 2. The slider 303 drives the transmission shaft 301 to move, so that the slider 303 on the outer wall of the transmission shaft 301 meshes with the gear body 4 and drives the slider 303 to rotate. The slider 303 drives the transmission shaft 301 to rotate, and the transmission shaft 301 drives the infrared receiver 304 to rotate. At the same time, the motor drives the infrared emitter 1110 to rotate, so that the positioning strip 1101 is always aligned with the infrared receiver 304, and the parallelism of the friction pad surface at different positions is detected.

[0054] Then, the friction plate lifting structure 10 drives the friction plate to move upward, so that the friction plate is in contact with the pressure plate 6. The servo motor 5 drives the pressure plate 6 to rotate, rubbing the friction plate. After rubbing, the friction plate undergoes the above steps to check the parallelism of the surface of the friction plate, and to check whether the friction plate can be evenly stressed.

[0055] The above-described embodiments are merely illustrative of certain implementations of the present invention, and are described in a relatively specific and detailed manner. However, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements are all within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
