New performance - Import export

The PMKP-110 absorber is a new high-performance shock absorber of increased energy intensity, class T1, to protect multi-purpose freight cars of general purpose from longitudinal loads. The device is developed on the basis of the commercially available draft gear PMK-110K-23, in which, instead of a spring set, a supporting-return device is used, which is a set of polymer elastic blocks. The use of polymer blocks increases the completeness and energy intensity of the shock absorber's power characteristics. This is achieved by increasing the rigidity of the retaining set, which makes it possible to reduce the control angles of the wedge system and, accordingly, to stabilize the friction on the auxiliary surfaces. In combination with the damping properties of polymers, frictional self-oscillations can be eliminated.
