The invention discloses an axle end nut locking assembly and an axle assembly. The axle end nut locking assembly comprises an axle, an axle head nut, a retaining washer and a clamping piece. The outer surface of the axle is provided with an external thread, the axle is provided with an extension section located at the outer side end of the external thread, and the extension section is provided with a first matching part; the axle head nut is arranged on the axle in a sleeving manner, an inner thread screwed outside the outer thread is arranged in an inner hole of the axle head nut, and a first clamping part is arranged on the axle head nut; the retaining gasket is arranged outside the extending section in a sleeving manner, a second matching part is arranged on the inner edge of the retaining gasket, the second matching part and the first matching part are meshed with each other to form a first limiting structure, a second clamping part is further arranged on the retaining gasket, and the second clamping part and the first clamping part are matched to form a second limiting structure; and the clamping piece is used for clamping and fixing the retaining washer on the shaft head nut. The influence of scrap iron on mounting of the shaft head nut is avoided, and the axial assembling precision of the shaft head nut is improved.
