[0002] The clutch mechanism of the tractor is a device used to control the connection and disconnection between the engine and the transmission system to achieve operations such as starting, shifting and parking. It is usually composed of a clutch disc, a pressure plate, a clutch separator, a clutch pedal and a linkage mechanism. When the driver steps on the clutch pedal, the clutch mechanism separates the separator from the pressure plate, and the contact force between the clutch disc and the pressure plate is reduced, so that the power of the engine cannot be transmitted to the transmission system. In this way, the driver can select the appropriate gear through the transmission to complete the shifting operation. When the clutch pedal is released, the clutch disc and the pressure plate contact again, and the power of the engine can be transmitted to the transmission system to achieve the driving of the vehicle.

[0022] Example:
[0023] See also Figure 1 - Figure 5 A tractor clutch mechanism comprises a frame 1 and a clutch 2, wherein the frame 1 is provided with a clutch 2, the left end of the clutch 2 is connected with a handwheel 3, the frame 1 is provided with a hydraulic mechanism 4, the hydraulic mechanism 4 is provided with a pedal 5, a disassembly component 6 is provided between the hydraulic mechanism 4 and the pedal 5, the hydraulic mechanism 4 is connected to the pedal 5 through the disassembly component 6, the frame 1 is connected to the pedal 5 through the disassembly component 6, a connecting component 7 is provided between the clutch 2 and the handwheel 3, and the clutch 2 is connected to the handwheel 3 through the connecting component 7.
[0024] By setting up the disassembly component 6, the purpose of quickly replacing the pedal 5 can be achieved, so that the staff can replace the pedal 5 by themselves, thereby saving the use cost required for replacing the pedal 5, and the staff can replace the pedal 5 for use anytime and anywhere; by setting up the connection component 7, the staff can replace the damaged handwheel 3 conveniently, and at the same time make it more efficient for the staff to replace the handwheel 3, thereby preventing the handwheel 3 from being damaged, resulting in the staff being unable to use the clutch 2 through the handwheel 3.
[0025] In other embodiments, the disassembly assembly 6 includes an assembly groove 61 provided on the right side surface of the hydraulic mechanism 4, a movable groove 62 is slidably connected in the assembly groove 61, a movable groove 62 is provided on the front end surface of the pedal 5, two groups of slide grooves 63 are symmetrically provided on the inner wall of the movable groove 62, guide blocks 64 are slidably provided in the slide grooves 63, slide bars 65 are provided on the outer walls of the guide blocks 64, a spring 66 is provided on the inner wall of the movable groove 62, the other end of the spring 66 is connected to the inner end of the slide bar 65, a handle 67 is provided on the outer end surface of the slide bar 65, two groups of plug blocks 68 are symmetrically provided on the rear end surface of the handle 67, and slots 69 are provided in the hydraulic mechanism 4 and the pedal 5 corresponding to the rear end surface of the plug block 68;
[0026] When in use, first pull the handle 67 in the direction away from the hydraulic mechanism 4, so that the handle 67 drives the slide bar 65 to slide in the movable groove 62, and the slide bar 65 synchronously drives the guide block 64 to slide in the slide groove 63, and at the same time the slide bar 65 continuously stretches the spring 66 until the handle 67 drives the plug block 68 to slide out of the slot 69, and then the pedal 5 can slide out of the assembly slot 61, so as to achieve the purpose of quick removal of the pedal 5. When it is necessary to install a new pedal 5, similarly, slide one end of the pedal 5 until it abuts against the inner wall of the assembly slot 61, and then release the handle 67. At this time, the restoring force of the spring 66 will drive the slide bar 65 to reset and slide in the movable groove 62, and the handle 67 synchronously drives the plug block 68 to slide into the slot 69, so that the plug block 68 abuts against the inner wall of the slot 69, so as to achieve the purpose of quick replacement of the pedal 5, so that the staff can replace the pedal 5 by themselves, thereby saving the use cost required when replacing the pedal 5, and it is convenient for the staff to replace the pedal 5 for use anytime and anywhere.
[0027] In other embodiments, the outer wall of the spring 66 is fitted to the inner wall of the movable groove 62, one end of the spring 66 is welded to the inner wall of the movable groove 62, and the other end of the spring 66 is welded to the inner end of the slide bar 65;
[0028] This design can limit the position of the spring 66 to prevent the spring 66 from being displaced in the movable groove 62, resulting in uneven elastic force output to both sides of the slide bar 65, which can easily cause the slide bar 65 to become stuck and unable to slide.
[0029] In other embodiments, the guide block 64 is designed in a semicircular shape, the slide groove 63 is provided as a through hole matching the semicircular shape, and the slide groove 63 and the guide block 64 are both adapted;
[0030] This design can improve the stability of the slide bar 65 when it slides back and forth in the movable groove 62, thereby preventing the slide bar 65 from shaking.
[0031] In other embodiments, the connecting assembly 7 includes a movable bin 71 disposed on the clutch 2, the handwheel 3 is slidably connected to the clutch 2, a bearing 72 is provided on the top surface of the movable bin 71, a stud bolt 73 is fixedly connected to the bearing 72, a brake disc 74 is provided on the bottom surface of the stud bolt 73, two groups of threaded blocks 75 are threadedly connected to the stud bolt 73, a limit plate 76 is provided on the rear end surface of the threaded block 75, and a limit groove 77 is provided on the surface of the handwheel 3 corresponding to the surface of the limit plate 76;
[0032] When the clutch 2 is in use, the hand wheel 3 is first sleeved on the clutch 2, and the limiting groove 77 on the hand wheel 3 is aligned with the limiting plate 76. Then, the brake disc 74 is rotated to enable the brake disc 74 to drive the stud bolt 73 to rotate on the bearing 72, and the stud bolt 73 is continuously acted on the two sets of threaded blocks 75 during rotation, so that the two sets of threaded blocks 75 move linearly on the stud bolt 73 and gather towards the middle of the stud bolt 73. While the threaded block 75 moves, it simultaneously drives the limiting plate 76 to slide into the limiting groove 77 until the surface of the limiting plate 76 abuts against the limiting groove 77 to achieve the purpose of installing the hand wheel 3, so that the staff can replace the damaged hand wheel 3, and at the same time make it more efficient for the staff to replace the hand wheel 3, and prevent the hand wheel 3 from being damaged, resulting in the staff being unable to use the clutch 2 through the hand wheel 3.
[0033] In other embodiments, the movable chamber 71 is detachably connected to the clutch 2 by bolts, and the bolts are pentagonal bolts;
[0034] With this design, when the movable chamber 71 is not needed, the movable chamber 71 is removed from the clutch 2 by bolts to reduce the external usable space of the clutch 2. When the movable chamber 71 is needed, the movable chamber 71 is installed on the clutch 2 by bolts for use.
[0035] In other embodiments, a ball bearing is built between the threaded block 75 and the movable chamber 71, and the threaded block 75 performs linear reciprocating motion in the movable chamber 71 through the ball bearing;
