The tractor clutch is through the operating mechanism, relying on the friction between the main and driven components, the engine and the transmission are temporarily separated and gradually engaged, so as to provide or cut off the transmission power and ensure the smooth shifting of the transmission system. Some wheeled tractors mostly use friction clutches. Friction clutches transmit power by friction between contact surfaces. The clutch driving disc is connected with the crankshaft of the engine and rotates with the crankshaft, and the driven disc is connected with the input shaft of the transmission.

When sufficient pressure is provided to press the driven piece and the driving piece together, the power of the engine is transmitted to the driven piece through the driving piece due to the friction of the contact surfaces of the principal and driven pieces. When the pressing force is canceled and the master and the follower are out of contact, the power of the engine cannot be transmitted to the follower. Tractor work requires that the clutch can transmit the maximum torque from the engine without slipping, the separation is rapid and complete, the rotational inertia of the driven disc is small, and the engagement is smooth; and the heat dissipation is better, and the operation should be light. If these requirements can not be completed or the completion is not good, it means that there is a fault in the clutch that needs to be identified and eliminated in time.

Tractor clutch manufacturers have conducted a detailed analysis of clutch failures often encountered in use.

 

1. Change of clutch free stroke13-inch

The clutch free travel refers to the distance that the clutch pedal moves from the start of the clutch pedal movement until the clutch starts to disengage. The clutch free stroke has a specified value, and it is not qualified if it is too large or too small. If the free stroke of the clutch is too large, the clutch is not completely separated, and the gear shifting is difficult, which will cause the driven disc to wear out: If the free stroke of the clutch is too small, the clutch cannot be fully engaged, the power cannot be fully transmitted to the transmission, and the driving is weak. The free travel of the clutch pedal is one of the conditions to ensure the reliable operation of the clutch. The free travel of the tractor clutch pedal should be checked regularly and adjusted if necessary.
