The invention discloses a tapered wedge and swing bolster elastic connection damping device for a wagon bogie and the bogie, solves the problems of low rhombus deformation resistance of the bogie andweak control capability between a swing bolster and a side frame due to vertical vibration and transverse vibration on a main friction surface in the prior art, and has the benefits of effectively improving the transverse performance of the bogie and improving the rhombus deformation resistance of the bogie. According to the specific scheme, the tapered wedge and swing bolster elastic connection damping device for the wagon bogie comprises the swing bolster, side frames and tapered wedges, the swing bolster is connected between the two side frames, the tapered wedges are arranged at the positions, where the side frames are arranged, of the swing bolster, and the tapered wedges are arranged between the swing bolster and the side frames; the tapered wedges are connected with the inner sidesof the side frames through mortise and tenon structures so that the tapered wedges can only move vertically, elastic pieces are arranged between the two side faces of each tapered wedge and the swingbolster and make contact with the tapered wedges and the swing bolster respectively, and damping springs are arranged on the bottom sides of the tapered wedges and the bottom side of the swing bolster.
本发明公开了一种铁路货车转向架用斜楔与摇枕弹性连接减振装置及转向架,解决了现有技术中主摩擦面处存在垂向振动和横向振动,使得转向架抗菱形变形能力低、摇枕与侧架间控制能力弱的问题,具有有效提高转向架的横向性能,提高转向架抗菱形变形能力的有益效果,具体方案如下:一种铁路货车转向架用斜楔与摇枕弹性连接减振装置,包括摇枕、侧架和斜楔,摇枕连在两个侧架之间,摇枕在其设置侧架位置处设置斜楔,斜楔设于摇枕与侧架之间,斜楔与侧架内侧通过卯榫结构连接以使得斜楔只有垂向运动,斜楔的两侧面与摇枕之间均设置弹性件,弹性件与斜楔、摇枕分别接触,斜楔与摇枕的底侧均设置有减震弹簧。
