The utility model discloses an adopt following technical scheme to realize:
the axle wheel edge sealing structure is characterized in that the shaft diameter of a half shaft oil seal is pressed into a center circular hole of an end face flange of a half shaft, and the outer end faces of the half shaft oil seal are aligned; the axostylus axostyle of semi-axis is packed into the axle housing assembly, and the sealing lip of semi-axis oil blanket cooperates with the axle diameter of axle housing assembly, and the terminal surface flange of semi-axis passes through bolted connection with wheel hub's terminal surface laminating, semi-axis terminal surface flange.
Furthermore, the half shaft is formed by welding a flange plate and a half shaft rod, and a central circular hole of the flange plate is matched with a circular outer spigot of the half shaft rod, and the end faces of the central circular hole and the circular outer spigot of the half shaft rod are attached to each other for axial limiting; the flange plate is provided with distribution holes for screwing the wheel hub; and the non-welded end of the circular hole in the center of the flange plate is used for mounting a half shaft oil seal.
Furthermore, an end part structure is arranged at the end part of the half shaft rod, and a spigot matched with the flange plate is arranged on the outer diameter of the end part flange structure; two spline shafts are arranged on the rod diameter of the half shaft rod, the spline shafts at the outer ends are used for connecting half shaft gears, and the spline shafts at the middle parts are used for connecting driving axle sliding meshing sleeves.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model provides an axle wheel limit seal structure, through adopting components of a whole that can function independently welding semi-axis structure, arranges the semi-axis oil blanket and installs on the flange terminal surface of semi-axis. The structure size of the half-shaft oil seal is reduced, the cost of the oil seal is reduced, and the sealing reliability is improved; the combined surface of the half shaft and the hub is contracted towards one side of the hub, so that the weight of the hub is reduced, and the cost is reduced.
