Novel active self-adaptive suspension mechanism

一种新型主动自适应悬架机构

Abstract

The utility model relates to a novel active self-adaptive suspension mechanism for a small-sized wheel type movable carrying platform at the bottom of the sea. The mechanism comprises six suspension rods, and a positive and negative quadrilateral structure is formed by the six suspension rods which are articulated with one another; one of the six suspension rods is replaced by a hydraulic cylinder, only tension and pressure are applied to the suspension rod, and the suspension rod has a two-force rod structure; extending ends of the another three suspension rods are respectively connected with a front wheel, a middle wheel and a rear wheel; and a damping spring is connected between the two parallel suspension rods. The suspension mechanism is deformed by the relative rotation of all rod pieces of the suspension mechanism so as to adapt to the change of terrain, so that the stability of a machine body is guaranteed; the height of a center of gravity of the machine body can be controlled by actively adjusting the extension of the hydraulic cylinder, so that the travelling stability of the movable platform can be guaranteed; and all the suspension rods are designed by a constant strength mechanism, and the damping spring is capable of effectively alleviating the impact coming from the uneven ground of the bottom of the sea, so that the service lives of the suspension mechanism and equipment carried by the suspension mechanism can be prolonged.
本实用新型涉及海底小型轮式移动搭载平台的一种新型主动自适应悬架机构,该机构采用6个悬架杆相互铰接形成正反四边形结构,其中一根悬架杆由液压缸替代只受拉压力作用,属于二力杆结构,其中三根悬架杆的伸出端分别与前、中、后轮相连,一根减震弹簧连接于两平行悬架杆之间。悬架机构各杆件之间发生相对转动使悬架机构产生形变可适应地形的变化,保证机体的平稳性,通过主动调节液压缸的伸缩量能够控制机体的重心高度保证移动平台行驶的稳定性,各悬架杆采用等强度机构设计,同时减震弹簧可有效缓和来自海底不平地面的冲击,提高悬架机构和所搭载设备的寿命。
