Abstract
A drive bogie for a crawler vehicle. The bogie comprises carrying wheels freely rotatably suspended on a solid or divided bogie beam. An endless crawler mat passes over the carrying wheels. At least one drive roll is provided, which drives the crawler mat and which is arranged to press the crawler mat against the wheels. The crawler mat is substantially resilient in every direction. The carrying wheels are suspended on the bogie beam so that the resilient crawler mat is pressed between the drive roll and carring wheels forming part of the bogie construction and situated at the sides of the drive roll.
