Further, described axle bowl assembly also includes left and right pad, and pad is located between bearing-type tooth plug and nut respectively.

Further, described axle bowl assembly also includes left and right locked spacer, respectively pad be located at bearing-type tooth plug and nut it Between.

Further, uniform three ages of a draught animal on the bearing-type tooth plug baffle ring in described left side, on the bearing-type tooth plug baffle ring on right side Uniform two ages of a draught animal.

Using technique scheme, this utility model is due to substituting rolling steel ball circle, big steel bowl accordingly with rolling bearing The outer rim of inwall and tooth plug is changed to plane and rolling bearing outer ring and inner ring tight fit, and the improvement of this structure, using rotary shaft Hold and can achieve relatively rotating of big steel bowl and rotating shaft, structure is simply, easy to install.
