FIELD: railway transport. SUBSTANCE: invention can be used in designing of passenger car bogies. Proposed bogie contains frame resting through primary springing system onto wheels axle boxes, and overspring beam designed for coupling with car body and resting on frame through secondary springing system. Hydraulic vibration dampers and device for suppressing high-frequency component of vertical vibrations installed in series with springs are used in primary and secondary springing system in parallel with springs. Said device 10 consists of elastic nonmetallic three-layer monoblock indestructible members. EFFECT: suppression of amplitudes of vertical components. 4 cl, 7 dwg |
