Transverse retaining shoulder reinforced damping fastener
The transverse retaining shoulder reinforced vibration reduction fastener. The fastener comprises a lower iron base plate, a middle elastic cushion, an upper iron base plate, two steel rail transverse limiting structures and a damping unit, wherein the middle elastic cushion is clamped by the upper iron base plate and the lower iron base plate; each steel rail transverse limiting structure comprises a blocking shoulder, a blocking table and a cushion block, the blocking shoulders and the blocking tables are arranged on the lower iron base plate and the upper iron base plate respectively, and the cushion blocks are clamped by the blocking shoulders and the blocking tables and generate elastic deformation; the damping unit is a piezoelectric unit body and/or a damper, the piezoelectric unit body comprises piezoelectric particles and conductive particles which are dispersed in the middle elastic cushion, the damper penetrates through the middle elastic cushion, and an upper end and a lower end of the damper are connected with the upper iron cushion plate and the lower iron cushion plate respectively. The fastener is advantaged in that on the basis that the transverse rigidity of the fastener is improved through the steel rail transverse limiting structure, the damping unit is further arranged between the upper iron base plate and the lower iron base plate, vibration energy of the steel rail is consumed through the damping unit, and the vibration impact buffering capacity of the fastener is further improved.
本发明公开了一种横向挡肩加强型减振扣件，包括下铁垫板、中间弹性垫、上铁垫板、两个钢轨横向限位结构和阻尼单元，上铁垫板和所述下铁垫板夹住所述中间弹性垫；每个钢轨横向限位结构均包括挡肩、挡台和垫块，挡肩和挡台分别设置在下铁垫板和上铁垫板上，垫块被挡肩和挡台夹住并且产生弹性变形；阻尼单元为压电单元体和/或阻尼器，压电单元体包括分散在中间弹性垫内部的压电粒子和导电粒子，阻尼器穿过中间弹性垫，阻尼器的上、下两端分别连接所述上铁垫板和下铁垫板。本发明通过钢轨横向限位结构来提高扣件横向刚度的基础上，在上铁垫板与下铁垫板之间还设置阻尼单元，通过阻尼单元消耗钢轨振动能量，进一步提高扣件缓冲振动冲击的能力。
