N-shaped arranged speed reducer shell for new energy vehicle

The invention relates to a N-shaped arranged speed reducer shell for a new energy vehicle. The shell comprises a shell cover and a shell body which are connected with each other, three-axis bearing holes, two-axis bearing holes and one-axis bearing holes are formed in the shell cover and the shell body, a differential mechanism assembly is arranged on one side of the shell body, a differential mechanism bearing hole is formed in the differential mechanism assembly, and the circle center connecting line among the differential bearing hole, the three-axis bearing holes, the two-axis bearing holes and the one-axis bearing holes form an N-shaped structure from the side view angle. According to the the speed reducer shell, a split design is adopted, so that casting, production and processing ofthe shell body and the shell cover are facilitated, and the subsequent assembly of gears and a bearing pack is facilitated; and the efficient lubrication of a speed reducer during low-high-speed advancing or low-speed retrea
