Articulated working machine
A working machine includes a first section with a first frame and at least one oscillation axle holding a first pair of ground engaging members; a second section with a second frame and a second pair of ground engaging members; a joint arrangement pivotly connecting the first frame to the second frame; a motor configured for driving one ground engaging member of the first pair of ground engaging members in order to create propulsion forces; a propulsion force transfer arrangement adapted to transfer propulsion forces from the ground engaging member of the first pair of ground engaging members to the second pair of ground engaging members, via the joint arrangement. The propulsion force transfer arrangement includes a connecting element extending centrally in a longitudinal direction of the working machine.
Method and control unit for preventing a rollover situation of an articulated vehicle
A method of preventing a rollover situation for an articulated vehicle, specifically in relation to the forward vehicle section of the articulated vehicle, is disclosed. A corresponding control unit and a computer program for such an articulated vehicle is also disclosed.
Work vehicle
A work vehicle (1) comprising a forward part (3) and a rearward part (7) pivotally coupled about a main vertical pivot axis (10) for steering thereof. A power take-off shaft (29) is located adjacent a forward end (31) of the forward part (3) and is mechanically driven from a main output drive shaft (15) of an engine (14) located in the rearward part (7). A step-up gearbox (20) steps up the speed from the main output drive shaft (15) onto first and second output shafts (23, 24) for driving first and second hydraulic pumps (27, 28) which provide hydraulic supplies for motive power and for operating attachments attached to the forward end (31) of the forward part (3). A step-down gearbox (30) receives drive directly from the main output drive shaft (15) of the engine (14) and produces a stepped-down drive on an output shaft (33) of the step-down gearbox (30) with a gear ratio of 2:1. A main drive transmission shaft (35) transmits drive from the step-down gearbox (30) to the power take-off shaft (29) at the regulatory speed of a power take-off shaft in the range of 540 rpm to 1000 rpm, thereby minimising the speed of the mechanical drive required from the rearward part (7) to the forward part (3), and reducing the mechanical drives required from the rearward part (7) to the forward part (3) to a single mechanical drive.

ARTICULATED WORKING MACHINE
A working machine includes a first section with a first frame and at least one oscillation axle holding a first pair of ground engaging members; a second section with a second frame and a second pair of ground engaging members; a joint arrangement pivotly connecting the first frame to the second frame; a motor configured for driving one ground engaging member of the first pair of ground engaging members in order to create propulsion forces; a propulsion force transfer arrangement adapted to transfer propulsion forces from the ground engaging member of the first pair of ground engaging members to the second pair of ground engaging members, via the joint arrangement. The propulsion force transfer arrangement includes a connecting element extending centrally in a longitudinal direction of the working machine.
Articulated vehicle
A vehicle has first and second parts with at least one road wheel. The first part pivotally connects to a connecting member at two spaced apart points to pivot about a first axis relative and the second part pivotally connects to the connecting member at two spaced apart points 18 to pivot about a second axis, which is perpendicular to the second axis, intersecting at a pivot point. A first drive shaft rotatably mounts to the first part and extends in a direction perpendicular to a longitudinal axis of the first part, a second drive shaft rotatably mounts to the second part and extends in a direction perpendicular to a longitudinal axis of the second part. The first and second drive shafts connect by a universal joint so that the two shafts to pivot relative to each other about the pivot point.
