所述轮组横梁的侧面设有横梁座板， 所述横梁座板位于减震垫组件的 下方处， 所述底盘主梁的底面上设有主梁座板， 所述连杆的两端分别铰接 于横梁座板和主梁座板上。
本发明进一步公开了一种自行走减震底盘， 包括轮组横梁、 底盘主梁 以及固定于轮组横梁下方的轮组， 所述自行走减震底盘上装设有上述的减 震装置。
与现有技术相比， 本发明的优点在于：
1、本发明砂浆设备用自行走底盘的减震装置及自行走底盘， 结构筒单 紧凑、 成本低廉、 安装方便、 减震效果好， 用于减小或消除在底盘行走时， 由于地面不平而引起的震动对砂浆车上装的影响， 同时可以弥补底盘主梁 的制造误差， 保证砂浆车上装与底盘主梁接触面紧密贴合。
