[0002] The clutch is located in the flywheel housing between the engine and the gearbox. The clutch assembly is fixed to the rear plane of the flywheel with screws. The output shaft of the clutch is the input shaft of the gearbox. While the car is driving, the driver can press or release the clutch pedal as needed to temporarily separate and gradually engage the engine and gearbox, thereby cutting off or transmitting the power input from the engine to the transmission. The clutch is a common component in mechanical transmissions that can separate or engage the transmission system at any time. The basic requirements for it are: smooth engagement, quick and complete separation; easy adjustment and repair; small overall dimensions; low mass; good wear resistance and sufficient heat dissipation capacity; easy and labor-saving operation.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] like Figures 1 to 7 As shown, the utility model provides a chromium-molybdenum-copper alloy cast iron clutch, comprising a clutch housing 1, a clutch main body mechanism 12 is slidably connected to the interior of the clutch housing 1, and a separation assembly 2 is mounted on the surface of the clutch housing 1;

[0027] The separation component 2 includes a support block 21. A plurality of support blocks 21 are symmetrically installed on the surface of the clutch housing 1. A fixed block 22 is installed on the surface of the clutch main body 12. A separation screw 23 is installed on one side surface of the support block 21. One end of the separation screw 23 passes through the clutch housing 1 and is slidably connected to the through hole opened on the surface of the fixed block 22 and extends to the outside of the fixed block 22. One end of the separation screw 23 passes through the fixed block 22 and is threadedly connected to a nut 24. The clutch housing 1 and the clutch main body 12 both adopt the "chromium-molybdenum-copper alloy cast iron" material structure. A tight component 3 is installed on the surface of the clutch housing 1, which can simplify the structure between the clutch housing 1 and the clutch main body 12, making it convenient for the operator to separate and disassemble the clutch housing 1 and the clutch main body 12, reducing the cost of separating and disassembling the clutch housing 1 and the clutch main body 12.

[0028] Specifically, a return spring 25 is sleeved on the surface of the separation screw 23, one end of the return spring 25 is connected to the support block 21, and the other end of the return spring 25 is connected to the clutch housing 1, so that the clutch housing 1 and the clutch main body mechanism 12 can be reset.

[0029] like Figures 1 to 7 As shown, the supporting blocks 21 and the fixing blocks 22 correspond one to one, thereby improving the connectivity between the clutch housing 1 and the clutch main body mechanism 12 .

[0030] Furthermore, a plurality of separation screws 23 are evenly distributed on the surfaces of the clutch housing 1 and the clutch main body 12 , thereby enabling connection processing at multiple locations of the clutch housing 1 and the clutch main body 12 .

[0031] It is worth noting that the clutch body mechanism 12 includes a plurality of pressing plates 26 therein.

[0032] like Figures 1 to 7 As shown, the tightening assembly 3 includes a tightening block 31, and a plurality of tightening blocks 31 are evenly installed on the surfaces of the plurality of pressure plates 26. An adjusting groove 32 is provided on the surface of the clutch housing 1 to match the tightening block 31. The tightening block 31 is slidably connected to the inside of the adjusting groove 32. A tightening rod 33 is commonly inserted between the plurality of pressure plates 26. The two ends of the tightening rod 33 are distributed and pass through the two pressure plates 26. A movable plate 34 is symmetrically installed on one side surface of the two pressure plates 26. A double-threaded rod 35 is slidably connected in the through hole opened on the surface of the movable plate 34. The double-threaded rod 35 is inserted into the inside of the tightening rod 33. One end of the double-threaded rod 35 passes through the movable plate 34 and the tightening rod 33 in turn, and extends to the outside of the other movable plate 34, so that the plurality of pressure plates 26 in the clutch main body mechanism 12 can be tightly processed to avoid collision between the plurality of pressure plates 26 during use, causing abnormal noise and the like.

[0033] It is worth emphasizing that both ends of the double-threaded rod 35 are threadedly connected with a nut 36, so that the position of the double-threaded rod 35 can be stabilized, so that the double-threaded rod 35 fixes the position of the tight rod 33.

[0034] The structure of the motor is prior art and will not be described in detail. Furthermore, the present invention also includes a power supply, a controller, and a switch, which are not the main technical points of this patent and will not be described in detail. The wiring diagram of the motor in this utility model is common knowledge in the field, and its operating principle is already known technology. The model is selected according to actual use, so the control method and wiring layout of the motor will not be explained in detail.

[0035] Working principle and process: When the clutch housing 1 and the clutch main body 12 are separated and disassembled, the nut 1 24 threadedly connected to one end of the separation screw 23 is first rotated to disengage the nut 1 24 from the surface of the separation screw 23. At this time, the operator pulls the clutch housing 1 as a whole, so that the support block 21 drives the separation screw 23 to disengage from the through hole opened on the surface of the fixed block 22. At this time, the clutch housing 1 is pulled so that the adjustment groove 32 opened on the clutch housing 1 is separated from the tight block 31 on the surface of the pressure plate 26 in the clutch main body 12, thereby realizing the separation and disassembly of the clutch housing 1 and the clutch main body 12. When the clutch housing 1 and the clutch main body 12 are in use, if the clutch housing 1 is hit, the clutch housing 1 drives the separation screw 23 to slide in the through hole opened on the surface of the fixed block 22 through the support block 21, and the tight block 31 slides in the adjustment groove 32 opened on the surface of the clutch housing 1. At this time, the support block 21 pushes the return spring 25 to deform, and the return spring 25 can reset the position of the clutch housing 1, thereby further improving the use effect of the device. Space is reserved between the clutch housing 1 and the clutch main body 12, thereby alleviating direct collision between the clutch housing 1 and the clutch main body 12;

[0036] When tightening the pressure plate 26 in the clutch main body mechanism 12, first insert the tightening rod 33 into the through holes opened on the surface of multiple tightening blocks 31. At this time, insert the double-threaded rod 35 into the movable plate 34, so that the double-threaded rod 35 passes through the movable plate 34 and the tightening rod 33 in sequence. At this time, the operator rotates the nut 2 36 so that the nut 2 36 is threadedly connected to the two ends of the double-threaded rod 35, thereby fixing the position of the tightening rod 33. At this time, the tightening rod 33 stabilizes the positions of multiple pressure plates 26. At this time, after the clutch housing 1 is installed on the pressure plate 26, the adjusting groove 32 can also tighten the tightening block 31 at the same time.

[0037] It should be noted that the clutch housing 1 and the clutch main body mechanism 12 are mature existing technologies, wherein the working process of the clutch main body mechanism 12 is as follows: when the diaphragm spring is installed between the clutch cover and the pressure plate, it is pre-compressed and deformed to form the pressure on the pressure plate, so that the clutch master and slave parts are pressed together, that is, the clutch is in the engaged state, and the engine power is transmitted to the driven plate through the flywheel, clutch cover and pressure plate connected to the crankshaft, and then transmitted to the input shaft of the transmission through the spline shaft sleeve of the driven plate. The working characteristics of this process are that the torque and speed transmitted by the master and slave parts of the clutch are the same, there is no speed difference between the master and slave parts, and there is no slip wear;

[0038] During the disengagement process, the clutch pedal is depressed, which moves the pedal and the push rod to the left. This, in turn, pushes the diaphragm spring release plate to the left via the cylinder and the working cylinder. This influences the diaphragm spring, which in turn uses the support pin fixed to the clutch cover as a fulcrum to move its large end to the right. Simultaneously, the release plate pulls the pressure plate to the right. Finally, a gap is created between the driven plate and the flywheel, and the pressure plate, and the clutch is disengaged. This completes the clutch disengagement process.

[0039] Engagement process: Release the clutch pedal, and the return spring returns it to its original position, simultaneously driving the push rod and release bearing back to their original positions. The movement of the operating mechanism during engagement is the reverse of the release process. When a gap forms between the release bearing and the diaphragm spring release plate, and the diaphragm spring re-presses the pressure plate against the driven plate, the engagement process is complete, and the clutch resumes its power transmission function.
