Упругий элемент гидропневматической подвески

A fluid suspension unit, particularly for heavy motor vehicles, comprising an outer cylinder and an inner cylinder slidably mounted within the outer cylinder, the outer and inner cylinders defining therein a chamber of variable volume containing hydraulic fluid and compressed gas. A diaphragm divides the chamber into two portions and has an opening therein which is normally closed by a mushroom valve. The upper portion of the chamber has a constant volume and a prefixed pressure and the lower portion has a variable volume and a variable pressure, lower or at most equal to that of the upper portion. The mushroom valve, normally closed, opens mechanically only when the suspension reaches a predetermined degree of compression that is when the pressure in the two portions of the chamber are the same. The valve is closed by gravity when the suspension returns to the same predetermined degree of compression.

Oscillation damper with gas- or liquid-filled spaces

Oscillation dampers for the oscillation damping of two components that can be moved relative to one another generally have gas- or liquid-filled spaces which are connected to one another via flow restriction openings. In vehicles, especially motor vehicles, use is generally made of hydraulic telescopic shock absorbers and these require a considerable installation space in the direction of compression. The new oscillation damper, in contrast, is to require less space in the direction of compression but nevertheless to have good damping properties both in the compression stage and in the extension stage. It has a dimensionally stable can-shaped first damper part with a storage space of constant volume and an axially adjacent second damper part with a first spring-damper space of variable volume enclosed by a rolling bellows. This space communicates via first flow restriction openings with the storage space and via second flow restriction openings with a second spring-damper space of variable ...
