The invention relates to the technical field of train seats, in particular to a train driver zero-rigidity vibration reduction seat, a vibration reduction assembly comprises an upper top plate and a lower bottom plate, deformable main supports are arranged at the two ends between the upper top plate and the lower bottom plate, and guide frames are fixedly arranged on the inner side walls of the main supports; a horizontally-arranged guide through groove is formed in the surface of the adjusting assembly in a penetrating mode, and the adjusting shaft is located at the intersection of the guide through groove and the guide frame and movably penetrates through the guide through groove and an inner cavity of the guide frame in sequence. The damping assembly has the beneficial effects that the adjusting assemblies are arranged in the upper area and the lower area of the main support correspondingly, the two adjusting assemblies are fixedly connected with the upper top plate and the lower bottom plate correspondingly, and when the whole damping assembly deforms due to vibration, the main support rotates and extrudes the adjusting shaft, so that the adjusting shaft horizontally slides in the length direction of the guide through groove; therefore, the connecting position between the main spring and the main support is changed, the absorption effect on vibration impact force is improved, and it is guaranteed that the damping assembly has better buffering and damping performance.
本发明涉及列车座椅技术领域,具体为一种列车驾驶员零刚度减振座椅,减振组件包括上顶板和下底板,上顶板和下底板之间的两端均设置有可形变的主支架主支架的内侧壁固定设置有导向架;调节组件的表面贯穿开设有水平设置的导向通槽,调节轴位于导向通槽和导向架的交叉处并依次活动贯穿导向通槽和导向架的内腔;有益效果为:通过在主支架上下两部分区域均设置有调节组件、且两个调节组件分别固定连接上顶板和下底板,当减振组件整体受振动而变形时,主支架旋转并挤压调节轴,使调节轴沿导向通槽长度方向水平滑动,从而改变主弹簧与主支架之间的连接位置,提高对振动冲击力的吸收效果,确保减振组件具有更加良好的缓冲减振性能。
