FIELD: machine building.SUBSTANCE: shock-absorbing device consists of an operating cylinder, in which two dividing pistons forming three operating chambers are located. There is one spring in each chamber. A nut of the operating cylinder, through which a stock passes, is screwed on both ends of the operating cylinder. One side of the stock is attached to the dividing piston to transfer forces to it, and its other side is provided with an eye lug for attachment to a car frame and a suspended lever. A stock cuff is installed between the stock and the nut of the operating cylinder. A high pressure pipeline, in which systems of compression and rebound valves and adjustable throttles are located, is provided from the upper operating chamber to the lower operating chamber. There is a branch between two adjustable throttles, which leads to the intermediate operating chamber. One more high pressure pipeline for supply of working liquid is connected to the upper and lower operating chambers, on each of which one control valve and one check valve is installed. One more pipeline is connected to the intermediate operating chamber for discharge of working liquid, on which a control valve and a check valve is installed as well.EFFECT: wide range of change of elastic damping characteristics of the shock-absorbing device.1 dwg |
