The operation process of the crawler truck clutch can be divided into the separation process and the engagement process. In the separation process, the clutch pedal is stepped on, and the free gap of the clutch is eliminated during the free stroke, and then the separation gap occurs during the operation stroke, and the clutch is separated. In the process of engagement, gradually loosen the clutch pedal of the crawler transporter, Rubber tracks series and the pressure plate moves forward under the effect of the tension spring. The separation gap is first eliminated, and the effect is sufficient on the pressure plate, driven plate and flywheel operating surface. Compressive force; in the future, the separation bearing moves backward under the effect of the reset spring, a free gap occurs, and the clutch is engaged.

During the operation of the clutch of a crawler transport vehicle, the driven disc will become thinner due to wear and tear, which will reduce the free gap, which will affect the normal engagement of the clutch. Therefore, the clutch needs to be adjusted after a period of operation. The intention of the clutch adjustment is to ensure a suitable free gap. The position and method of the clutch adjustment are determined by the detailed crawler vehicle model.

The pressure plate is an automatic part of the clutch, which always rotates with the flywheel. Generally, it can be driven by a boss, key or pin to make it rotate together with the flywheel. At the same time, the pressure plate can move backward relative to the flywheel to separate the clutch. The driven disc of the crawler transport vehicle is mainly composed of the driven disc body, the conflicting piece and the driven disc hub. During the process of clutch separation to engagement of the crawler transporter, the conflicting disc, the flywheel and the pressure plate will conflict, and a lot of heat will be generated. The heat needs to be dissipated out of the crawler transport vehicle in time to prevent the conflict disc from being damaged due to excessive temperature. Therefore, there are windows on the clutch cover, and some also have air guide fins to enhance the internal ventilation and heat dissipation.
