PURPOSE:To allow a leveling function to be added by inserting a hydraulic stabilizer, consisting of a pair of hydraulic cylinders suppressing pitching of a cab, to be interposed between a car body frame and the cab and connecting a hydraulic pressure source through a selector valve to chambers mutually in an opposite side in both the hydraulic cylinders. CONSTITUTION:In the case of a truck mounting to a front end part of a frame constituting a body of the truck a cab 11 through a cab suspension device consisting of front and rear suspension springs 12, 13, a hydraulic stabilizer, comprising front and rear hydraulic cylinders 15, 16, is mounted interposing between the body frame 10 and the cab 11. The front and rear hydraulic cylinders 15, 16 are connected in a manner wherein a chamber mutually in an opposite side for a piston communicates by communication pipes 19, 20. The communication pipes 19, 20 are connected respectively to accumulators 21, 22 each connected to a selector valve 23 controlling pressure oil supplied and discharged, and the selector valve 23 is controlled in its rotary position by a microcomputer 24. |
