SIDE SUPPORT OF RAILWAY CAR BODY ON BOGIE Russian patent published in 1994 - IPC

FIELD: railway transport. SUBSTANCE: side support comprises flexible member 3 and support plates 4 and 5 secured rigidly on body 1 and bogie 2, respectively. One end of flexible member 3 is connected with its support plate directly while the other end, via a slide disposed between guides on support plate 5. Side support is provided with a device for limiting horizontal motion of the slide relative to support plate 4 of the opposite end of flexible member 3 made as a combination of flat stops 15 and 16 whose working surfaces are perpendicular to guides of support plate 5, and brackets 17 and 18 with stop cams 19 and 20 installed in a spaced relation to working surfaces of stops 15 and 16. Relative motions of points of body 1 and bogie 2 square to guides of support plate 5 and parallel to them within the limits of the gap are effected due to shear deformation of flexible member 3, i. e. without friction and wear of support parts. Displacement of slide relative to support plate 5 takes place when the size of said gap is exceeded in this direction, i.e. only on changes of track curvature in plan. EFFECT: lower friction and wear of support elements resulting in higher reliability of support. 3 dwg
