Vibration reduction connecting piece and pre-compression type track vibration reduction structure
The invention belongs to the technical field of rail traffic, and particularly relates to a vibration reduction connecting piece and a pre-compression type rail vibration reduction structure. The vibration reduction connecting piece comprises an outer sleeve and an inner sleeve which are coaxially arranged, and an elastic sleeve arranged between the outer sleeve and the inner sleeve; at least two kerfs are formed in the outer sleeve and/or the inner sleeve in an annular array around the axis of the outer sleeve and/or the inner sleeve; and the at least two kerfs cut the outer sleeve and/or the inner sleeve into at least two parts. After the vibration reduction connecting piece is installed, the outer sleeve and the inner sleeve have a certain compression force on the elastic sleeve, so that the outer sleeve and the inner sleeve are tightly attached to an installation hole and a spike, large transverse rigidity can be provided, part loss caused by friction between parts is avoided, and the connection stability of the shock absorber is guaranteed. Compared with pure rigid connection of the spike and the installation hole, the stability of the spike, the friction vibration and noise between the spike and the shock absorber and the vertical or transverse shock absorption and transition performance are greatly improved; and compared with the mode that only the elastic sleeve is arranged between the spike and the mounting hole, the connecting rigidity and the connecting stability are better.
本发明属于轨道交通技术领域，具体是涉及到一种减振连接件及预压缩式轨道减振结构，包括同轴设置的外套和内套，以及设置在外套和内套之间的弹性套，外套和/或内套上以其轴线呈环形阵列设置有至少两个割缝，至少两个割缝将外套和/或内套分割为至少两瓣，本发明在安装后外套和内套即对弹性套具有一定压缩力，使外套和内套紧贴安装孔和道钉，可以提供大横向刚度，也解决了各部件之间摩擦造成的零件损耗，保证减振器的连接稳定性。相对于道钉和安装孔纯刚性连接而言，其道钉的稳定性、道钉和减振器之间的摩擦振动、噪声以及垂向或横向减振和过渡的性能大大提升；而相对于在道钉与安装孔之间仅设置弹性套而言，本发明的连接刚度和连接稳定性更好。
