The invention relates to a chassis structure for a working machine moving on a terrain, the chassis structure comprising a pair of front wheels and a pair of rear wheels supporting the frame, and a controlled frame joint between the frame parts, when the frame is composed of two frame parts. The chassis structure further comprises a suspension controlled by actuators and arranged to move each wheel in a level transverse in relation to the frame. Each wheel is mounted rotatably and to turn by the actuators to the suspension, and each wheel is usually provided with a hub motor for drive transmission. The chassis structure can further comprise a pair of middle wheels for a second frame part. In a method related to the chassis structure the forest machine can also be turned in place. |
