FIELD: machine engineering.
SUBSTANCE: invention relates to the rail vehicle, in particular to the auto-oscillation suppressors of the freight car truck wagging. An auto-oscillation suppressor of the freight car truck wagging includes a rigid horizontal frame and means of the wagging suppression. Means of the wagging suppression contain a double-arm lever and two identical pneumo-amortisseurs with the possibility of air pumping into their rodless cavities with adjustable leaking. The horizontal suppressor frame is fixed to the lateral frames of the truck. The short arm of the double-arm lever is a part of the rocker engagement with the center sill of the car. Two pneumoclamps, the most extended rods of which are directed in a straight way from the both sides of the center cill, are rigidly fixed on the horizontal frame. The rodless cavities of the pneumo-amortisseurs are interconnected and with the cylinders of the pneumoclamps.
EFFECT: increased efficiency of the auto-oscillation suppressor is achieved.
