Problems solved by technology

[0003] Due to the irregular space of the front cabin, the small space, and the large number of parts arranged, it is not conducive to the design and layout of the motor and reducer with a low integration level at present, which makes the design and layout of the front cabin parts of the whole vehicle difficult. Difficult to arrange

Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings.

[0020] see figure 1 , The motor is mainly composed of a front end cover 1, a rear end cover (integrated with a junction box) 2, a motor body 3, and a rotor shaft 4. The front end cover 1 is an irregular shape, on the assembly surface with the reducer 7, with the motor shaft 4 as the center, five studs 5 connected to the flange surface of the reducer 7 are distributed on half of the side, and the other half A through hole 6 connected with the flange surface of the reducer 7 is provided on each of the three radially outwardly protruding parts, and connected to the flange surface of the reducer 7 . Two positioning pin holes 8 are additionally designed on the front end cover 1, and the positioning pins are used to cooperate with the positioning pin holes 9 on the flange surface of the reducer. The junction box 12 is installed on the rear end cover 2 of the motor. The fr...

Abstract

The invention discloses a driving motor of a pure electric automobile. The driving motor comprises: a motor body, a drive end baring bracket and a commutator end bearing bracket. The drive end baring bracket is in an irregular shape and is arranged on a mounting surface of a reducer. Taking a motor shaft as a center, five studs, which are connected with a flange face of the reducer, are arranged on a half side, and through holes, which are connected with the flange face of the reducer, are respectively arranged on radial outward convex positions of the other half side so as to connect the flange face of the reducer. An upper edge of the drive end baring bracket is wider than the upper edge of the flange face of the reducer, and suspending installing holes are arranged on a part which exceeds the upper edge of the flange face so as to install a suspending support. By using the invention, a space structure in a front cabin can be reasonably used. The structure is compact, reasonable, practical and reliable.

Description

technical field [0001] The invention belongs to the technical field of motors, and in particular relates to a pure electric vehicle drive motor. Background technique [0002] At present, the driving motors of pure electric vehicles are basically arranged in the front cabin of the vehicle. The installation structure is usually as follows: a regular front-end cover is designed on the motor, and a stopper and several mounting holes are designed on the front-end cover. Through the motor The spigot is concentrically positioned with the input shaft of the reducer, and then the motor and the reducer are connected together by bolts to ensure power transmission. The rear end cover of the motor is designed with a junction box and a mounting hole for the suspension bracket on the axial boss, which occupies axial space. [0003] Due to the irregular space of the front cabin, the small space, and the large number of parts arranged, it is not conducive to the design and layout of the mot...
