Title: A WORKING MACHINE COMPRISING AT LEAST ONE PROPULSION AXLE
Abstract:
The invention relates to a working machine (1, 101, 201) comprising a working machine frame (20, 120, 220), at least one propulsion axle (10, 110, 210) having an elongated main body (11, 111) comprising a first end portion (112), a second end portion (113) and a center portion (111C) arranged between the first and second end portions, each one of the first and the second end portions being adapted to be equipped with a propulsion hub (14, 114) for driving a working machine propulsion means. The elongated main body has a main body length (MBL) extending from the first end portion to the second end portion. The working machine further comprises a linkarm arrangement (15, 115, 215) pivotably connecting the propulsion axle with the working machine frame such that the roll axis (RA1) of the propulsion axle relative the working machine frame is comprised in the linkarm arrangement. At least the portion of the linkarm arrangement comprising the roll axis is positioned above the center portion of the propulsion axle.
