Crawler Chassis Structure And Working Principle

The crawler chassis parts mainly includes the chain group(lien de suivi & chaussure de piste), track/bottom roller, oisif, Rouleau porteur, pignon et la structure du cadre au milieu.

Le galet de roulement est utilisé pour supporter et disperser le poids mécanique sur la piste.

Le support/rouleau supérieur is to maintain the linear movement of the chain rail.

Le galet est utilisé pour guider la piste pour tourner correctement, empêcher sa déviation, déraillement de la voie et réglage de l'étanchéité de la voie.

Le sprocket and segement is fixed on the traveling reducer to transmit the power of the traveling motor to the crawler.

Usually, the motor or diesel engine or hydraulic motor provides power, and the driving wheel rotates to drive the crawler movement and plays a supporting role.

When the crawlers on both sides move forward at the same time, the whole crawler chassis parts moves forward, the crawlers on both sides move backward at the same time, and the whole crawler chassis parts moves backward. When there is a speed difference between the two crawlers, the differential steering movement will be realized.
