Description

Technical Field

[0001] The invention relates to a clutch structure.

[0002] Background technology solution

[0003] The clutch is located in the flywheel housing between the engine and the gearbox, and its output shaft is the input shaft of the gearbox. During the driving process of the car, the driver can step on or release the clutch pedal as needed to temporarily separate and gradually engage the engine and the gearbox to cut off or transfer the power input from the engine to the transmission. The clutch includes electromagnetic clutch, friction clutch, etc. The friction clutch squeezes the pressure plate through the diaphragm spring, so that the pressure plate squeezes the friction plate, so that the flywheel drives the friction plate to rotate.

[0004] During the use of the clutch, the friction plate will continue to wear, which will cause the thickness of the friction plate to become thinner, making it impossible for the pressure plate to completely squeeze the friction plate, which will reduce the service life of the equipment. In addition, during use, the friction plate will generate a large amount of heat, and the current equipment cannot dissipate the heat, causing the equipment to age due to heat, which in turn reduces the service life of the equipment. Therefore, a clutch structure is urgently needed to improve the above problems. Summary of the invention

A squeezing mechanism 12 is provided on the top of the adjusting mechanism 8 to enable the adjusting mechanism 8 to move up and down.

[0024] Reference Figure 2 , Figure 3 and Figure 4The adjusting mechanism 8 includes a pressing plate 13, a telescopic rod 14 is arranged on the top of the pressing plate 13, which can be extended and retracted, a spring 15 is arranged on the outer surface of the telescopic rod 14, and a rotating plate 16 is arranged on the top of the telescopic rod 14. The adjusting mechanism 8 can squeeze the friction plate 7, thereby controlling whether the turntable 3 rotates. A ventilation hole 17 is opened inside the pressing plate 13 to dissipate heat. The vertical position of the ventilation hole 17 is different from that of the telescopic rod 14. The outer surface of the housing 9 is provided with a heat dissipation hole 18, which can dissipate heat for the equipment, thereby slowing down the thermal aging of the equipment, thereby extending the service life of the equipment.

[0025] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 A connecting block 19 is fixedly connected to the top edge of the rotating plate 16, and a sliding block 20 is arranged on the top of the shell 9, which can move up and down. A mounting block 21 is fixedly arranged on the top of the shell 9 on one side of the sliding block 20, which can limit the connecting rod 22. The lower part of the mounting block 21 is connected to the connecting rod 22, and the connecting rod 22 can rotate relative to the mounting block 21. One end of the connecting rod 22 is fixedly connected to the connecting block 19, and the other end is located below the sliding block 20 and contacts with the sliding block 20, so that the pressing plate 13 can move up and down, and then whether the turntable 3 can rotate can be controlled.

[0026] The extrusion mechanism 12 includes a sleeve 23 with an internal thread. A rotating ring 24 is provided on the top of the sleeve 23 and an external thread is provided on the bottom. Sliders 25 are provided on both sides of the rotating ring 24, which can enable the rotating plate 16 to move up and down, and then enable the pressing plate 13 to move up and down, so that the device can always squeeze the pressing plate 13 with the same force, thereby extending the service life of the device.

[0027] Reference Figure 1 , Figure 2 , Figure 4 and Figure 6 The slider 25 is adapted to the slide groove 10, and the slider 25 is slidably connected to the slide groove 10. A positioning pin 26 is provided on the outer surface of the rotating ring 24, which can rotate the rotating ring 24, so that the pressure plate 13 can move up and down. A connecting key 27 is provided at the bottom of the rotating shaft 4, and a key groove 28 cooperating with the connecting key 27 is provided inside the turntable 3. The limit ring 6 and the turbine 5 are fixedly connected to the rotating shaft 4, so that the rotating shaft 4 can rotate with the turntable 3, so that the device can output power outward.

[0028] The implementation principle of the present invention is:

[0029] The clutch structure is provided with a connecting shaft 2, which is connected to the output shaft of the motor, so that the connecting shaft 2 can rotate with the motor. When the clutch is pressed, the sliding block 20 will move downward. The downward movement of the sliding block 20 can drive one end of the connecting rod 22 to move downward. The connecting rod 22 is limited by the mounting block 21, so that the connecting rod 22 can rotate, and then the connecting block 19 can move upward, and then the rotating plate 16 can be driven to move upward. The upward movement of the rotating plate 16 can drive the telescopic rod 14 to extend and the spring 15 can be restored to its deformation, so that the pressure plate 13 is no longer subjected to downward pressure. As the rotating plate 16 continues to move upward, the pressure plate 13 will be separated from the friction plate 7, so that the friction plate 7 can be separated from the flywheel 1, so that the turntable 3 can stop rotating. The stop of the rotation of the turntable 3 can stop the rotation of the rotating shaft 4, so that the device can no longer output outward.

[0030] When the clutch is released, the sliding block 20 moves upward, which can drive the pressure plate 13 to move downward, so that the friction plate 7 can contact the flywheel 1, and the shaft 4 can rotate. The rotation of the shaft 4 can drive the turbine 5 to rotate. The rotation of the turbine 5 can extract the heat generated by the friction plate 7 and enter the top of the pressure plate 13 through the ventilation hole 17. Then, the heat can be dissipated to the outside of the housing 9 through the heat dissipation hole 18, thereby slowing down the thermal aging of the equipment and extending the service life of the equipment.

[0031] When the friction plate 7 becomes thinner, the positioning pin 26 is rotated to rotate the rotating ring 24, and the rotating ring 24 can rotate by sliding the slider 25 inside the slide groove 10. The rotation of the rotating ring 24 can move the sleeve 23 downward, and the downward movement of the sleeve 23 can drive the rotating plate 16 to move downward, and then drive the pressure plate 13 to move downward, thereby offsetting the thickness of the friction plate 7 worn, and thereby enabling the pressure plate 13 to squeeze the friction plate 7 with the same force, thereby preventing the pressure plate 13 from being unable to generate sufficient force after the friction plate 7 becomes thinner, thereby extending the service life of the equipment.
