[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. During the driving of the vehicle, the driver can step on or release the clutch pedal as needed to temporarily separate and gradually engage the engine and the gearbox, so as to cut off or transmit the power input from the engine to the transmission.

[0003] After the clutch operates for a long time, the friction plate will have the phenomenon of overheating, which will cause the friction plate to be ablated and adhere to the engine turntable and cannot be separated, thus affecting the shifting operation of the vehicle and the normal driving of the vehicle.

[0012] (3) Beneficial effects (1) In the present invention, through the connecting heat conduction ring, heat conduction rod, second heat conduction rod, elastic capsule, air extraction fan blade ring, bottom ring, and heat dissipation pipe arranged in the temperature reduction mechanism, under the action of air flow and friction, air enters the heat dissipation pipe during the rotation of the friction plate. While circulating in the heat dissipation pipe, it collides with the flow disturbing convex blocks, causing the air flow in the heat dissipation pipe to be disordered, enhancing the heat exchange effect between the air and the heat conducted from the friction plate to the heat dissipation pipe, dissipating heat from the friction plate, and preventing the friction plate from being overheated and burned out.

[0013] (2) In the present invention, through the auxiliary heat dissipation capsule and elastic air pipe arranged in the temperature reduction mechanism, when the engine output fluctuates, the auxiliary heat dissipation capsule can be squeezed to extract the air between the friction plate and the engine turntable and eject it upward. When the temperature of the friction plate is not in the high-temperature state, it can accelerate the air flow speed between the friction plate and the engine turntable and inside the housing, inhibit the heating speed of the friction plate, and prevent the temperature of the friction plate from rising too fast in a short time when the friction plate and the engine turntable rub against each other.

[0014] (3) In the present invention, through the touch rod, induction valve block, heat receiving cavity, third heat conduction rod, air guide ring, air outlet pipe, and L-shaped nozzle arranged in the drying mechanism, after the pressure in the heat receiving cavity increases to a certain extent under the action of the friction between the third heat conduction rod and the engine turntable, it can be ejected through the L-shaped nozzle to dry the friction plate at the bottom end of the friction disc, accelerating the drying speed of the friction plate, and preventing the friction disc from slipping after the vehicle wades through water, affecting the normal driving of the vehicle.

[0015] (4)In the present invention, through the elastic cleaning plate, electromagnet ring, and L-shaped nozzle provided in the drying mechanism, under the action of magnetic force, the L-shaped nozzle can rotate to eject the air in the heating cavity upward to blow the elastic cleaning plate, causing the elastic cleaning plate to swing between the separation springs to clean between the tops of the separation springs, preventing debris from sticking between the tops of the separation springs after the vehicle wades through water, which affects the air flow in the housing and thus the heat dissipation effect of the housing.

[0021] The drying mechanism 8 is uniformly and fixedly connected to the elastic cleaning plate 801 on the inner wall of the top end of the outer shell 1.

An electromagnet ring 809 is fixedly connected to the middle part of the top end of the outer shell 1.

An exhaust port is arranged at the end of the L-shaped nozzle 808 far from the induction valve block 803. A magnetic ball is fixedly connected to the end of the L-shaped nozzle 808 far from the induction valve block 803. The magnetic poles of the magnetic ball and the electromagnet ring 809 are opposite to each other. The bottom end of the air outlet pipe 807 passes through the arc-shaped opening and is located at the bottom end of the arc-shaped opening. Oval openings are provided on the parts of the third heat conducting rod 805 passing through the turntable 5 and the connecting plate 4. The area of the oval opening on the turntable 5 is larger than that of the oval opening on the connecting plate 4. Limiting rods are fixedly connected to both sides of the part of the third heat conducting rod 805 placed in the oval opening on the connecting plate 4, and the limiting rods are fixedly connected to the oval opening. A friction block is arranged at the bottom end of the third heat conducting rod 805. The intervals between the magnetic ball and the separation springs 9 are on the same vertical line.

[0022] During use, when the temperature of the friction plate 6 gradually rises, the temperature inside the friction plate 6 is conducted to the air inside the elastic bladder 704 through the second heat-conducting rod 703, the heat-conducting rod 702, and the connecting heat-conducting ring 701, heating the air inside the elastic bladder 704 and increasing the pressure inside the elastic bladder 704, so that the elastic bladder 704 elongates and pushes the air-extracting fan blade ring 705 downward, making the bottom end of the air-extracting fan blade ring 705 closely adhere to the top end of the connecting block 401. The rough surfaces at the bottom end of the air-extracting fan blade ring 705 and the top end of the connecting block 401 cause the connecting block 401 to drive the air-extracting fan blade ring 705 to rotate through friction. The rotation of the air-extracting fan blade ring 705 draws external air into the space between the bottom end of the air-extracting fan blade ring 705 and the bottom ring 706 and enters the heat-dissipating tube 707 through the circular air inlet on the friction disc 3, making the air flow rapidly in the heat-dissipating tube 707 and collide with the turbulence bumps 710, causing the air flow in the heat-dissipating tube 707 to be disordered and enhancing the heat exchange effect between the air in the heat-dissipating tube 707 and the heat conducted from the friction plate 6 to the heat-dissipating tube 707, thereby improving the heat dissipation effect on the friction plate 6 and further dissipating heat from the friction plate 6. Also, when the friction plate 6 is in close contact with the engine turntable 5 and drives the rotation between the friction disc 3 and the connecting disc 4, when the engine output fluctuates, the connecting disc 4 squeezes the buffer spring 501, causing the auxiliary heat-dissipating bladder 708 inside the buffer spring 501 to contract and draw the high-temperature air between the bottom ends of the friction disc 3 into the auxiliary heat-dissipating bladder 708 through the elastic air tube 709. When the engine output fluctuates again, the auxiliary heat-dissipating bladder 708 is squeezed again to spray the high-temperature air inside the auxiliary heat-dissipating bladder 708 to the top end of the auxiliary heat-dissipating bladder 708, further improving the heat dissipation effect on the friction plate 6.

[0023] When the vehicle wades through water, the small air supply device 2 starts to inject air into the heat-receiving cavity 804 through the air supply pipe 201. The heat generated by the friction between the engine turntable 5 and the friction block at the bottom of the third heat-conducting rod 805 is conducted to the heat-receiving cavity 804 through the third heat-conducting rod 805 to heat the air in the heat-receiving cavity 804, increasing the pressure in the heat-receiving cavity 804. When the heat-receiving cavity 804 is fully expanded, the induction valve block 803 automatically opens, allowing the air in the heat-receiving cavity 804 to be ejected through the L-shaped nozzle 808. At this time, under the action of the magnetic ball, the L-shaped nozzle 808 guides the air in the heat-receiving cavity 804 placed in the elliptical groove into the air outlet pipe 807 and ejects it through the air outlet pipe 807 to blow the friction plate 6 at the bottom of the friction disc 3, accelerating the drying speed of the moisture on the surface of the friction plate 6 and preventing the friction plate 6 from slipping, which may affect the normal driving of the vehicle. At the same time, after the air in the heat-receiving cavity 804 is discharged, the small air supply device 2 continues to fill the heat-receiving cavity 804 with air, and the air in the heat-receiving cavity 804 is continuously heated by the friction between the third heat-conducting rod 805 and the engine turntable 5. After the drying of the friction plate 6 is completed, an electric current is passed into the electromagnet ring 809, causing the L-shaped nozzle 808 to rotate under the action of the magnetic force of the electromagnet ring 809, making the magnetic ball on the L-shaped nozzle 808 face upward. When the driver steps on the clutch pedal, the separation spring 9 pushes the touch rod 802 downward. When the touch rod 802 contacts the heat-receiving cavity 804, the induction valve block 803 opens, allowing the air in the heat-receiving cavity 804 to be ejected upward to blow the elastic cleaning plate 801 between the separation springs 9, causing the elastic cleaning plate 801 to continuously swing between the separation springs 9, thereby cleaning the space between the separation springs 9 to prevent debris from accumulating between the top intervals of the separation springs 9 after the vehicle wades through water, blocking the top of the outer shell 1 and affecting the dissipation of heat inside the outer shell 1.
