PURPOSE:To permit good drive feeling by supporting a cab onto a frame through a plurality of expandable actuator and allowing a desired spring constant and a damping characteristic to be set, in a suspension apparatus for supporting the cab of a truck etc. CONSTITUTION:Installation shafts 3 and 4 are installed onto the front edge part of the frame 1 of a truck and the upper edge part of a rear arch 2, and further installtion shafts 6 and 7 are installed at the position opposite to the installation shafts 3 and 4 at the front and the rear parts of the cab 5, and actuators 10 are interposed between installation shaft (3, 6) and (4, 7). Said cab 5 is rotatably supported around the installation shaft 3 through a link mechanism 8 installed on the both sides in the front part, and a driving means 9 for tilting cab is installed between the frame 1 and the cab 5. Said driving means 9 is connected to a working-liquid feeding source 40 through a manually-operated selector valve 38 and an electromagnetic selector valve 39, and each actuator 10 is connected to the working-liquid feeding source 40 through electromagnetic selector valves 45 and 39. |
