Determine area, add the reliability of machinery, but motor internal is a set of hub bearing double row angular contact bearing, in practical operation,
Bearing is difficult to bear the superposed forces such as automobile gravity, magnet steel suction, motor driving force, causes bearing life to reduce, and bearing clearance is big,
Rotor swing is big, has a strong impact on motor overall performance.
In addition, existing hub motor structure design is unreasonable, make its manufacture that inconvenience to be installed, expense is bothersome, limits it
Concrete application, it is also very poor using reliability.
The content of the invention
The technical problems to be solved in the utility model be to provide it is a kind of it is rational in infrastructure, manufacture easy for installation, cost is low, reliable
Property the stable new-energy automobile hub motor structure of good and overall performance.
In order to solve the above-mentioned technical problem, new-energy automobile hub motor structure of the present utility model, an including side end face
Closing, the unlimited housing of other side end face and in housing by silicon steel sheet and the winding structure being wrapped on silicon steel sheet
Into stator, the mounting hole coordinated with automobile rim is provided with the end face at housings close end, housing is arranged on by fastener
The medial extremity of automobile rim, the open end formation inner chamber of the housing, the middle part of housing also have stretch to inner chamber and with housing one
Body formed central shaft, in addition to the stator seat with installation set, installation set are installed on center shaft by inner bearing and make peace
The outer rim for filling seat is arranged on the inner surface of housing by outer bearing, and stator is arranged on outside the installation set of stator seat, stator seat and shell
Being formed between the inner chamber of body has magnet steel of the radial direction ring cloth on housing inner circumferential surface in placing chamber, placing chamber, magnet steel is with determining
The winding position of son is relative.
The oil sealing of the outer ledge positioned at outer bearing is provided between the stator seat and housing.
The end face of the stator seat is provided with for the mounting hole with vehicle bridge or automotive suspension connection.
The oil outlet and inlet nozzle passed in and out for cooling oil is provided with the stator seat.
The terminals of power supply machine wire extraction are provided with the stator seat, being provided with waterproof sealing on the terminals connects
Head.
The utility model has the advantage of：
The mounting hole being connected with wheel rim is provided with its housing, it is possible thereby to directly and be completely disposed in automotive hub, no
It is only easy for installation, it is time saving and energy saving, greatly facilitate automobile integral arrangement and its reasonable in design is compact, make its manufacturing cost
Also it is very low, in addition, the structure installed between stator and housing by interior outer bearing is installed, it is ensured that electromechanics structure
Reliability, overall performance is stable, furthermore rational topology layout, motor can be made to fix solid reliable with automotive suspension, simultaneously
Also the oil nozzle to cooling oil reserves position, using cooling oil circulating cooling, the power and overload capacity of the motor that can be multiplied.
