TRW brand Suspension Sphere, pneumatic suspension are designed to accumulate energy with the help of a pump during its underload and return it in a short period of time when the power consumed exceeds the power developed by the pump.

If the operation of the hydraulic system is very uneven, then by turning on the accumulator, it is possible to reduce the pressure pulsation caused by the uneven operation of the pump and increase the efficiency of the hydraulic system. In addition, the suspension sphere as an attached container smooths out hydraulic shocks.

The construction of the pneumatic suspension sphere

Suspension spheres distinguish between pneumatic, cargo and spring. In the hydraulic drives of tractors, agricultural, construction and road machines, spring and pneumatic piston suspension spheres have become widespread.

The pneumatic suspension sphere consists of a closed cylinder (case), inside which is placed a piston, sealed along the outer diameter with two round rings made of oil-resistant rubber. The piston divides the interior of the accumulator into two chambers: an upper one filled with an inert gas and a lower one filled with pressurized oil.
