Correctly Adjust the Tractor Clutch

The clutch is an indispensable important component on the tractor. It is used to transmit and cut off the power transmitted by the engine to the gearbox and power output device, and to prevent damage of the parts when the drive train and power output device are overloaded.

 

The tractor clutch transmits torque by the friction force generated by the active friction plate and the driven friction plate, and the magnitude of the friction force depends on the value of the friction plate pressing force and the nature of the surface material of the friction plate. However, with the increase in the number of uses or improper use, the tractor clutch transmission mechanism will wear out, and the clutch friction plate will also become thinner due to wear, so that the friction force of the main and driven parts of the clutch is weakened, affecting the normal use of the vehicle. Therefore, after the tractor clutch is used for a period of time, it should be adjusted according to needs, which can effectively reduce the damage of the clutch, increase the use efficiency, extend the use period, and obtain better economic benefits.

 

The inner end of each tractor clutch release lever must be in contact with the release bearing at the same time for the vehicle to start smoothly. If the inner end of the release lever varies, the clutch will shake when it is engaged. Therefore, during assembly and maintenance, it is necessary to check the contact between the inner end of each separating lever and the separating bearing. The inner end of each separating lever is required to lie on the same plane. If it does not meet the requirements, it should be adjusted. The method is to adjust the position of the adjusting screw on the inner or outer end of the separation lever.

 

For the diaphragm spring clutch, if the diaphragm spring separation means that the load on the diaphragm spring is uneven or reduced due to wear, corrosion, cracking, etc., it must be updated. Diaphragm spring separation must be evenly arranged on the circumference, and the limit deviation is not more than 0.5 mm. At the same time, the height of each spring separation finger should be on the same horizontal plane, and the error should not be greater than 0.5 mm. If the spring separation finger is uneven, it will make the vehicle start unstable, tremble, and the tractor clutch cannot be completely separated.

 

Due to the frequent use of tractor clutches, the clutch operating mechanism first requires light handling to reduce the driver's labor intensity. The ease of operation includes two aspects: one is that the force applied to the tractor clutch pedal should not be too large, generally 196 to 245 N; the second is that the total stroke of the pedal should be within a suitable range (generally 100 to 150 mm, the maximum is no more than 180 mm). If it does not meet the requirements, it should be adjusted.
