Novel damping fastener
The invention relates to the technical field of rail transit components, in particular to a novel damping fastener which can ensure reliable fixation of a vibration isolation rubber pad and ensure the vibration reduction effect and comprises a sleeper, and an under-plate base plate, a lower iron base plate and a floating iron base plate are sequentially arranged on the sleeper from bottom to top. Wherein the under-plate base plate and the lower iron base plate are fixed on a sleeper through threads at the lower ends of the studs, two ends of the floating iron base plate are sleeved on polish rod sections of the studs, compression springs and nuts are arranged at the upper ends of the studs, the steel rail and the under-rail base plate are arranged on the upper end face of the floating iron base plate, and a vibration isolation rubber pad is arranged below the floating iron base plate. The novel damping fastener is characterized in that notches used for installing a vibration isolation rubber pad and a sliding sleeve are formed in the under-plate base plate and the lower iron base plate, bosses are installed at the two ends of the lower iron base plate, a through hole is formed in each boss, a columnar protrusion matched with the corresponding through hole is arranged on one side of the sliding sleeve, and a clamping ring matched with a protruding block at the bottom of the floating iron base plate is arranged on the other side of the sliding sleeve. The side face of the vibration isolation rubber pad abuts against the inner wall of the notch and the sliding sleeve.
本发明涉及轨道交通部件技术领域，具体为一种新型减振扣件，其能够确保隔振橡胶垫可靠固定，确保减振效果，其包括轨枕，轨枕上从下至上顺次设置有板下垫板、下铁垫板、浮置铁垫板，板下垫板和下铁垫板通过双头螺栓的下端螺纹固定于轨枕上，浮置铁垫板两端套装于双头螺栓的光杆段，双头螺栓上端设置有压缩弹簧和螺母，钢轨和轨下垫板安装于浮置铁垫板上端面，浮置铁垫板下方设置有隔振橡胶垫，其特征在于，板下垫板和下铁垫板上开设有用于安装隔振橡胶垫和滑套的缺口，下铁垫板两端安装有设置有凸台，每个凸台上开设有通孔，滑套一侧设置有与通孔配合的柱状凸起，滑套另一侧设置有与浮置铁垫板底部凸块配合的卡圈，隔振橡胶垫侧面抵住缺口内壁和滑套。
