FRICTION DAMPENER FOR RAILROAD CAR TRUCK |
摘要 |
<p>FRICTION DAMPENER FOR RAILROAD CAR TRUCK A three-piece dampener assembly provides means to depress vertical and horizontal oscillations between ends of a bolster of a railroad car truck and side frames of the truck. This assembly includes a control or friction shoe having an outer vertical engaging surface for contact with a vertical wear plate of a pocket formed in the side frame and an inner projecting triangular-shaped segment. The triangular segment is cowered by a relatively low friction adapter and engages a like triangular-shaped wedge slot formed in a control or friction shoe housing. The housing further includes an inclined wear surface for engaging with a complementary inclined friction surface formed in the bolster and a bottom surface for supporting engagement with a coil spring carried in the side frame pocket below the bolster. -i-</p> |
