The invention provides an electric drive car split type main speed reducer shell and an automobile. The main speed reducer shell comprises an outer connecting part and an inner supporting part. A shell large flange is arranged on the supporting part. A connecting part female end is arranged inside the shell large flange. A supporting part male end is arranged at one end of the inner supporting part. The supporting part male end penetrates into the connecting part female end and is welded and connected to the connecting part female end. The other end of the inner supporting part is connected tothe interior of the outer connecting part. The shell large flange is connected with a drive motor. The electric drive car split type main speed reducer shell further comprises a middle sleeve. Roundholes are formed in the two side faces on the outer connecting part. The middle sleeve runs through the two round holes and is in overlapped joint with the inner walls of the round holes. The middle sleeve is in welded connection with the inner walls of the round holes. According to the electric drive car split type main speed reducer shell, the drive motor is in rigid connection with a main speedreducer assembly to be integrated, the integrated body does not need to be independently fixed to a car frame or a car body, the arrangement space of the whole automobile is reduced, the transmissionefficiency is improved, the production efficiency is improved, the production cost is lowered, and the casting defect risk is lowered.
Description
technical field [0001] The invention relates to the technical field of the main reducer housing of an automobile, in particular to a split type main reducer housing of an electric drive vehicle and an automobile. Background technique [0002] The main reducer of an automobile is an assembly component that can realize the functions of deceleration, torque increase, inter-wheel differential speed and change of force transmission direction according to structural requirements. In the new energy electric drive vehicle models, for the main reducer directly driven by the drive motor, the existing installation method is that the drive motor is connected with the frame and the body, and the final reducer is connected with the frame and the body. The existing integration level is low, the layout space of the vehicle chassis is large, the structure is not compact enough, and disassembly and assembly are inconvenient. Contents of the invention [0003] The invention provides a split...
