Please also refer to Fig. 2 and Fig. 3, Fig. 2 is that the axle of the wedge of prior art is surveyed scheme drawing; Fig. 3 looks scheme drawing for the left side of wedge shown in Figure 2.
Because the left surface and the right flank of bolster 11 ends are inclined downward, and the left side wall of the central square frame at bogie side frame 13 middle parts and right side wall are vertical plane, therefore the cross-sectional plane of wedge 14 is a wedge shape shown in Figure 3, so that closely cooperate with the sidewall of the central square frame at the side of bolster 11 ends and bogie side frame 13 middle parts.
Wedge 14 has main friction face 141 (being shown among Fig. 3) and secondary friction face 142, and both contact with the sidewall of the central square frame at bogie side frame 13 middle parts and the side of bolster 11 ends respectively.For fear of bolster 11 and bogie side frame 13 wearing and tearing, and in order to improve friction effect, the side of the sidewall of the central square frame at bogie side frame 13 middle parts and bolster 11 ends is captive joint column wearing plate 16 and inclined-plane wearing plate 17 respectively.
Owing to be subjected to the restriction of bolster 11 structures, therefore two square plates that inclined-plane wearing plate 17 is provided with about normally side by side form the groove that is parallel to bolster 11 sidewalls, i.e. a wedge groove between two inclined-plane wearing plates 17.
Be provided with wedge spring 15 between the diapire of the central square frame at the bottom surface 141 of wedge 14 and bogie side frame 13 middle parts.When described rolling stock travels, between the main friction face 141 of column wearing plate 16 and wedge 14, have certain pressure between the secondary friction face 142 of inclined-plane wearing plate 17 and wedge 14.
In the Vehicular vibration process, bolster 11 and wedge 14 repeatedly carry out up-and-down movement along with moving of bolster 11, between the main friction face 141 of column wearing plate 16 and wedge 14, between the secondary friction face 142 of inclined-plane wearing plate 17 and wedge 14 owing to produce and relatively move and mutual friction mutually, therefore cause that the kinetic energy of body vibrations can be converted into the interior energy that friction produces, thereby realize the friction damping of vehicle.
