Abstract:
A modular crawler-track unit for a forest machine has an engine, a chassis with a pivot bearing and a crawler-track frame. A sleeve shaft is attached to the crawler-track frame to support the crawler-track frame on the pivot bearing. A drive wheel is mounted in bearings in the crawler-track frame inside a circulation of a crawler mat. A support is arranged in the crawler-track frame inside the circulation to support a part of the crawler mat against the ground. A drive shaft is mounted in bearings in the crawler-track frame coaxially with the sleeve shaft to transmit power to the crawler-track unit. A shaft mounted in bearings on the crawler-track frame pivots the drive wheel to the crawler-track frame at a distance from the drive shaft. A power-transmission is fitted between the shaft and the drive shaft to transmit power from the drive shaft to the drive wheel.
