The invention discloses a liftable universal driving wheel, which belongs to the technical field of driving wheels of special large transport vehicles, is rotatably mounted at the tail end of a suspension arm of a wheel seat, and comprises a steering seat, a support, a lifting arm and a lifting oil cylinder, wherein the steering seat comprises a fixed shell, a driving cavity communicated with the fixed shell, a mounting bottom hole formed in the top of the fixed shell, and a turbine seat fixedly connected to the interior of the fixed shell; the support is composed of a connecting disc and an inclined arm, the tail end of a connecting shaft is installed in a pin shaft base in the center of the bottom of the driver, and an encoder is installed at the outer end of a lower pin shaft and used for detecting the included angle between the support and the lifting arm. Compared with the prior art, the steering seat adopts a worm and gear structure, 360-degree free rotation of the wheel is achieved, the connecting shaft adopts a detachable scheme and can be conveniently replaced and maintained, the lifting arm does not need to be integrally replaced when the connecting shaft is damaged, and in addition, the encoder is installed at the outer end of the lower pin shaft so that the lifting height of the driving wheel can be accurately calculated.
本发明公开了一种可升降的万向驱动轮,属于特种大型运输车驱动轮技术领域,该万向驱动轮可旋转的安装在车轮座的悬空臂末端,包括转向座、支座、举升臂和举升油缸,其中:转向座包括定壳体、与定壳体连通的驱动腔、设置在定壳体顶部的安装底孔、固连在定壳体内部的涡轮座;支座由连接盘和斜臂组成,连接轴的末端安装在驱动器底部中央的销轴座内,下销轴的外端安装有编码器,编码器用于检测支座和举升臂之间的夹角。与现有技术相比,该转向座采用蜗轮蜗杆结构,实现了车轮360°的自由旋转,连接轴采用可拆卸方案能够方便更换、维护,连接轴受损时不用整体更换举升臂,此外,该下销轴的外端安装有编码器能够精准计算驱动轮的升降高度。
