Abstract

The invention discloses a right box of a bi-gear gearbox assembly of an electric vehicle. The front side of the right box body is a box body combined surface, the box body combined surface is provided with eight bolt mounting holes and two positioning pin holes circumferentially, the inner side of the box body combined surface is a form cavity, and the left portion of the bottom of the form cavity is provided with output bevel gear mounting holes. The bottom of the middle lower portion of the form cavity is provided with a bearing mounting sinking platform, and the bottom of the right upper portion of the form cavity is provided with an input shaft mounting hole. The left upper portion of the rear side of the right box body is provided with two first suspension mounting holes, the rear side of the right portion of the right box body is a motor mounting portion, and a motor mounting surface of the rear side of the motor mounting portion is provided with four threaded holes. The inner side of the motor mounting surface of the motor mounting portion is a motor mounting cavity, and the front side of the motor mounting portion is provided with two first suspension mounting holes. The right box is compact in structure, high in strength and convenient to be arranged on the gearbox assembly, and can be used as a mounting base for positioning pins, output bevel gears, bearings, an input shaft, a motor and suspensions.

Description

technical field [0001] The invention belongs to the field of transmission assembly, and in particular relates to a right box body of a transmission assembly of a second-speed electric vehicle. Background technique [0002] The existing electric vehicle transmission assembly has only one gear position, that is, it cannot change speed, its output speed and torque are constant, and it cannot be adjusted accordingly according to the road conditions, which leads to its poor adaptability to road conditions. [0003] In order to improve the road condition adaptability of the transmission, it is now necessary to redesign an electric vehicle transmission assembly with two gears. At the same time, in the design process, it is necessary to design a right box body, which not only has a compact structure and high strength, but also can reliably serve as the installation base for various components. Contents of the invention [0004] The technical problem to be solved by the present in...
