压路机常见的两大分类

发布者:wubaiyi发表时间:2017-12-22

按碾轮分类

碾轮构造有光碾、槽碾和羊足碾等。光碾应用*普遍,主要用于路面面层压实。采用机械或液压传动,能集中力量压实突起部分,压实平整度高,适于沥青路面压实作业。

按轮轴分类

按轮轴布置有单轴单轮、双轴双轮、双轴三轮和三轴三轮等种。以内燃机为动力,采用机械传动或液压传动。一般前轮转向,机动性好,后轮驱动。为改善转向及碾压性能,宜采用铰接式转向结构和全轮驱动。前轮框架和机架铰接,以减少路面不平时的机身摆动。后轮和机架为刚性联接。采用液压操纵、用液压缸控制转向。前后碾轮均装有刮板以清除碾轮上粘结物。还装有喷水系统,用于压实沥青路面时,对碾轮洒水以防沥青混合料粘附。为增大作用力还可在碾轮内加装铁、砂、水等加大压重。
