摘要： This invention concerns an arrangement (1) intended to be mounted at a vehicle (2) intended for forestry, comprising a load-bearing part (3) and driving bogie wheels (4) where the arrangement (1) comprises at least two extra wheels (5) that can be individually controlled in the vertical direction where each extra wheel is arranged at a shaft (6) that is fixed and that is not rotatable, pivotable, and is arranged at the frame (7) of the vehicle in order to distribute the weight of the machine. The individually controlled extra wheels (5) are subject to a driving force and mounted at least two arms (12) arranged at the frame of the vehicle, that a track (18) is placed around each set of bogie wheels (4) and the extra wheel (5) in order to protect against skidding and to distribute the weight, reducing the ground pressure, and that a tension arrangement (19) in the form of a cylinder under pressure or a coiled spring unit is arranged at each arm in order to absorb motions in the length of the arm (12) such that the length of the track does not change when the arm (12) moves up and down. The invention concerns also a vehicle (2) comprising such an arrangement (1).

摘要： This invention concerns an arrangement (1) intended to be mounted at a vehicle (2), comprising a load- bearing part (3) and driving wheels (4), where the arrangement (1) comprises at least two extra wheels (5) that can be individually controlled in the vertical direction and that are mounted at the vehicle (2) in order to distribute the weight of the vehicle, the gross weight of the vehicle including its payload weight, over more areas of the support (6), the ground, and in this way improve the distribution of weight and reduce the pressure exerted against the support, the ground. Each of the individually controlled extra wheels (5) comprises a pair of wheels and is subject to a driving force. The invention concerns also a vehicle (2) comprising such an arrangement (1).

摘要： The invention concerns an arrangement and a terrain-going motor vehicle. At a terrain-going motor vehicle (1 ) that has a chassis with wheel axles (12, 13) and pairs of wheels (12:1, 13:1 ), a half-track unit (15:1, 15:2) with half-track assembly (15) arranged at a wheel axle. For the regulation of the ground pressure, each half-track assembly (15) comprises: a pivotable arm (20) with a tracker wheel (22) that can pivot centrally to a driving wheel (12:1; 13:1 ) in a vertical plane at the chassis through a joint, a continuous track (24) that runs around tracker wheels (22) and driving wheels (12:1; 13:1 ), a hydraulic system including a piston-cylinder device (25) for the setting of the pivotable arm into angular positions (a) including an inactive position, and an operating condition, a positional valve (29), which valve when set to a first operating condition (A) leads hydraulic medium to the piston-cylinder device (25) for the setting of the pivotable arm (20) and the tracker wheel (22) to the operating condition and in interaction with the support, a third operating condition (C) leads hydraulic medium from the piston-cylinder device (25) for the setting of the pivotable arm (20) and thus also the tracker wheel (22) to the inactive position and away from interaction with the ground, whereby the tracker wheel (22) is placed in the first operating condition (A) in contact with the ground at a pre-determined force.
