Liquid resistance type high-grade vibration reduction fastener for rail transit
The invention relates to a hydraulic resistance type high vibration reduction fastener for rail transit, which comprises a rail bearing plate, a frame base, a vulcanized rubber structure, a bottom plate, an elastic unit, oil and a damping plate, the rail bearing plate is sleeved in the frame base, and an open cavity is enclosed by the vulcanized rubber structure; the damping plate is arranged in the open cavity, the elastic unit and the oil liquid are filled in the open cavity, and the rail bearing plate, the frame base and the vulcanized rubber structure are vulcanized into a whole and are connected with the bottom plate in a sealed mode. Different from a traditional steel rail fastener which generally adopts a rubber solid medium for vibration reduction design, the liquid resistance type high-grade vibration reduction fastener provides elasticity through gas compressibility, provides damping through oil viscous flow, can flexibly adjust rigidity and damping, and is assembled into a sealing structure through a vulcanized rubber structure and a bottom plate, so that the service life of the steel rail fastener is prolonged, and the service life of the steel rail fastener is prolonged. Therefore, the leakage problem of oil and gas is avoided, and the safety of train operation is ensured by arranging a transverse limiting structure and a vertical limiting structure.
本发明涉及轨道交通用液阻型高等减振扣件，包括承轨板、框架底座、硫化橡胶结构、底板、弹性单元、油液、阻尼板，所述承轨板内套于所述框架底座，通过所述硫化橡胶结构围合成一个开口腔室，所述开口腔室内设置所述阻尼板以及填充所述弹性单元和所述油液，所述承轨板、所述框架底座以及所述硫化橡胶结构硫化成一体，且与所述底板密封连接。不同于传统钢轨扣件普遍采用橡胶类固体介质进行减振设计，本发明的液阻型高等减振扣件由气体压缩性提供弹性、油液粘滞流动提供阻尼，刚度和阻尼可灵活调节，硫化橡胶结构与底板组装成密封结构，从而避免了油液和气体的泄露问题，设置横向和垂向限位结构，确保列车运行的安全性。
