TIE TAMPER VIBROPLATE SUSPENSION Russian patent published in 1994 - IPC

FIELD: railway maintenance machines; tie tampers. SUBSTANCE: suspension has longitudinal beams installed at both sides from longitudinal symmetry plane of machine. Beams are hinge-connected to track machine frame by means of telescopic rods. Vibroplates with wedges are suspended from longitudinal beams through flexible members. Suspension has also Y- shaped levers. Ends of lever horizontal wings are connected with corresponding lifting mechanism, and free ends of vertical legs of levers are installed for turning around vertical axles arranged in zone of end sections of longitudinal beams in longitudinal symmetry plane of machine. Secured machine frame are supports to installed lower ends of vertical axles whose upper ends are made fast on machine frame. Two rods forming turning mechanism of T-shaped lever are installed on vertical axles for turning around the axles by means of hydraulic cylinders. Rods are installed in mirror-like symmetry at both sides of longitudinal symmetry plane of machine. Resilient members hinge-connected with vertical leg of corresponding T-shaped lever are fastened to rods. EFFECT: enhanced operation reliability. 2 cl, 4 dwg
