Abstract

The invention refers to a spring shock absorber destined especially for buffers and traction devices of the rail vehicles; while it may have other applications as well, in others technical domains where it is necessary to absorb shocks. The shock absorbing spring, according to present invention, is composed by a tubular cylinder (1), or ring-shaped cylinder Z sealed at one end and divided by a diaphragm a with central guiding and sealing system (b), into two coabal rooms (c) and (d), in room (d) being mounted a piston (3) or several concentric pistons (4, 6) respective (6, 7), piston having its head (e) set at certain distances to the ends of the piston's rod, a rod f from one end of the piston's head (e) being mounted into the guiding and sealing system (b), while the other rod (g) from the other end of the piston's head being mounted into the guiding and sealing system (h) made of a cap (8) that closes the room d of the cylinder. Room (c) is filled with gas or compressible crude rubber (9) at a certain pressure level, and the room (d) is filled with hydraulic oil (10) at atmospheric pressure. The rooms (c) of the cylinders of the shock absorbing springs mounted into the shock or traction devices of the railcars can be interconnected in various configurations, ensuring the adaptation of the force - travel characteristic depending on the railcar situation (whether it is passing through curves, applying shocks to an isolated railcar or to a railcar in a convoy).
