Abstract
The utility model relates to a differential device shell, in particular to the differential device shell with a differential lock. The differential device shell with the differential lock comprises a shell body. A differential cavity is formed in the shell body. The left side end of the differential cavity is provided with a left half shaft hole communicated with the shell body. The right side end of the differential cavity is provided with a right half shaft hole communicated with the shell body. The upper portion and the lower portion of the inner wall of the differential cavity are respectively provided with a planet gear positioning spherical surface. The upper portion and the lower portion of the differential cavity are respectively provided with a planet shaft hole. The planet shaft holes are communicated with the planet gear positioning spherical surfaces. The left half shaft hole and the right half shaft hole are distributed horizontally in the same straight line. The two planet shaft holes are distributed in a vertical symmetry mode. An oil path is formed in the shell body. The outer wall of the tail portion of the shell body is provided with spline teeth which are evenly distributed. The differential device shell with the differential lock is compact in structure, high in assembly accuracy, and capable of improving using performance.
