Stator core bracket

Abstract

The invention relates to a stator core bracket. The bracket comprises a main bracket body and a secondary bracket body which are formed by stretching raw materials, the main bracket body comprises a main supporting surface and an outer circumferential surface, the secondary bracket body comprises a secondary supporting surface and an outer positioning part, inner holes of the main bracket body andthe secondary bracket body are formed in the outer surface of a shaft sleeve in a clearance fitted mode, the main supporting surface and the secondary supporting surface are inclined towards two sides from inside to outside in the radial direction, and the outer positioning part of the secondary bracket body abuts against the inner surface of the end part of the outer circumferential surface of the main bracket for positioning. The bracket has the advantages that the overall strength is high, load bearing performance of the overall structure is greatly improved by optimizing the structure onthe basis of using the same material, a motor with larger power can be borne by arranging a stator core with a larger size, raw materials are reduced and the cost is saved, concentricity and coaxiality are improved, and the phenomenon of swinging is eliminated as far as possible.

Description

technical field [0001] The invention relates to a motor component, in particular to a stator core support. Background technique [0002] With the continuous development of electric vehicles, electric vehicles are becoming more and more popular as a means of green transportation. They are gradually promoted from flat road areas such as cities to areas with complex road conditions such as rural areas and mountainous areas, especially in rural areas. In terms of agricultural transportation, some conventional electric vehicles for cities have the following problems: insufficient motor power, weak climbing, inability to carry heavy loads, insufficient structural strength during heavy loads, and low load-bearing capacity, which seriously hinder the use of electric vehicles in rural areas. , the use and popularization of mountainous areas.

[0002] With the continuous development of electric vehicles, electric vehicles are becoming more and more popular as a means of green transportation. They are gradually promoted from flat road areas such as cities to areas with complex road conditions such as rural areas and mountainous areas, especially in rural areas. In terms of agricultural transportation, some conventional electric vehicles for cities have the following problems: insufficient motor power, weak climbing, inability to carry heavy loads, insufficient structural strength during heavy loads, and low load-bearing capacity, which seriously hinder the use of electric vehicles in rural areas. , use and popularization in mountainous areas

[0003] The stator core support of an electric vehicle is an important load-bearing component. During the working process, the stator support not only bears the constantly changing torque and electromagnetic field force of the motor itself, but also bears the impact force of the wheel hub when it is bumped. Gravity, its own structural strength is very important. At present, the stator core o
