Axle pivoting controller and hydraulic cylinder for industrial vehicles |
摘要 |
A hydraulic apparatus is used in an industrial vehicle. The apparatus has a hydraulic cylinder interposed between a vehicle frame and an axle swingably coupled to the frame. A passage connects a first chamber with a second chamber defined by a piston in a cylinder case. The piston is movable based on differential pressure in the chambers. A cylinder rod selectively extends and retracts in respect with the cylinder case to absorb a swinging motion of the axle. The passage is selectively open and closed based on at least one of a traveling state and a loading state of the vehicle. The piston has a first surface defining the first chamber and a second surface defining the second chamber. The first surface has an area equal to that of the second surface.
