摘要
Abstract
The paper introduces the main structure and characteristics of the hydraulic wheel holding and lifting mechanism, which is applied in a towbarless aircraft tractor. The wheel holding and lifting mechanism includes the two parts of holding mechanism and lifting mechanism. The holding mechanism mainly has four structural forms. Two forms of them are applied widely on account of their simple and symmetric structure, and small working space. The lifting mechanism mainly have twirling form and lifting form. The twirling form has simple structure, but its dimension is large, because of the load of the spherical hinge which combines the framework and the carrying bucket. However the lifting form dimension is small, because the framework and the carrying bucket are combined by connecting rods, and every rod is a two-force rod.关键词
