    摘要： The invention relates to a hydraulic cylinder device to be used at a suspension arrangement for shock, noise and vibration damping suspension of an operator cab (2) on a frame of a working machine. The same comprises a hydraulic cylinder (5) having a cylinder body (6) having an inner cylinder space (7), a piston (8), a piston rod (9), wherein the piston delimits two hydraulic fluid chambers having variable volumes and more precisely a first hydraulic fluid chamber (34) on the side of the piston which is facing away from the piston rod, as well as a second hydraulic fluid chamber (39) on the piston rod side of the piston, hydraulic fluid passages through the cylinder body to the first as well as the second hydraulic fluid chamber for feeding of hydraulic fluid via hydraulic lines (25, 27) to and from the respective hydraulic fluid chamber, as well as an at least partly gas filled accumulator (16) which is in hydraulic fluid communication with the first hydraulic fluid chamber. The first hydraulic fluid chamber (34) and the accumulator (16) are connected via a first throttle (33) and a first one-way valve (32), which are coupled in parallel to each other and of which the first one-way valve allows hydraulic flow from the first hydraulic fluid chamber but blocks hydraulic flow in the opposite direction. The piston (8) comprises two through flow passages (35) which connect the first and second hydraulic fluid chambers (39) and of which one through flow passage is a second throttle (37) while the second is a second one-way valve (36) which allows hydraulic flow from the first to the second hydraulic fluid chamber but blocks hydraulic flow in the opposite direction. Moreover, the hydraulic fluid passage to and from the second hydraulic fluid chamber comprises a third throttle (38).

    摘要： The invention relates to a chassis structure for a working machine moving on a terrain, the chassis structure (40, 60) comprising a pair of front wheels and a pair of rear wheels supporting the frame (41 to 42, 61 to 62), and a controlled frame joint (63) between the frame parts (41, 42, 61, 62), when the frame is composed of two frame parts. The chassis structure (40, 60) further comprises a suspension (1a) 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 means of the actuators to the suspension, and each wheel is usually provided with hub motor means for drive transmission. The chassis structure (40, 60) can further comprise a pair of middle wheels for a second frame part (42, 62). In a method related to the chassis structure (40, 60) the forest machine can also be turned in place.
