Embodiment Construction

[0042] Such as figure 1 , 2 As shown in the figure, an N-shaped layout of the new energy vehicle reducer housing includes a shell cover 1 and a shell 2 connected to each other. Both the shell cover 1 and the shell 2 are provided with three-axis bearing holes, two-axis bearing holes and a Shaft bearing holes, one side of the housing 2 is equipped with a differential assembly 8, the differential assembly 8 has a differential bearing hole, and the differential assembly 8 is provided with a differential bearing 9, a bearing Cover 10, bearing cover bolt 11;

[0043] The connection line between the differential bearing hole and the three-axis bearing hole, the second-axis bearing hole, and the first-axis bearing hole on the housing cover 1 forms an "N"-shaped structure from a side view; the differential bearing hole and the housing 2 The line connecting the center of the three-axis bearing hole, the second-axis bearing hole, and the first-axis bearing hole forms an "N"-shaped stru...

Abstract

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 retreating of the whole vehicle is guaranteed through various oil baffles and oil grooves ingeniously designed on the shell body and the shell cover.

Description

technical field [0001] The invention relates to the technical field of lubricating reducers for new energy light truck drive axles, in particular to an N-shaped arrangement of reducer shells for new energy vehicles, which can effectively solve the problem of poor lubrication of the internal gears and bearings of the reducer when the pure electric light truck is moving forward and backward at low speed Hidden dangers, to ensure the reliable operation and comfort of the vehicle. Background technique [0002] With the acceleration of the electrification of automobiles, the electrification of commercial light trucks has been recognized as the next market explosion point. The industry generally adopts parallel-axis electric drive axles in which the motor is directly connected to the reducer. Usually, a larger reduction ratio can effectively reduce the overall size and weight of the product, so the center of each gear in the reducer will be arranged in an N-shaped posture; the lub...
