ABSTRACT:
A front-wheel driving apparatus for use in tractors and the like has bevel-gear cases one each of which a front-wheel case is fitted for free rotation about a kingpin axis, the front-wheel case being adapted to support a front wheel and accommodate therein a bevel-gear train which is for incorporating the kingpin and the front wheel. Both upper and lower end portions of the kingpin are supported on the bevel-gear case via the respective bearings, and are provided with the respective bevel pinions as mounted thereon so as to exert axial thrusts on the kingpin in directions opposite to each other, and further with the respective thrust retainers as secured thereon for taking up any possible overall balance thrust. A hub base is consolidatedly incorporated in the front-wheel case, and on the hub base there is fitted, for free rotation, through a bevel gear fixture base a bevel gear which meshes with the lower bevel pinion on the kingpin. The front wheel is mounted on an outer end portion of the bevel gear fixture base.
