Abstract
The invention provides a hub motor with external spline shaft. Based on a traditional motor with three asynchronous machines and through the design change of shape and structure, the invention is allowed to be a hub motor with reliable performance, simple structure and strong practicality. Two sides of a motor shell are provided with motor pedestals perpendicular to motor shafts so as to continent for connecting with a suspension of an electric vehicle; the external end of the motor shafts are provided with the external spline and a wheel connector; a wheel and a brake drum or a brake disk are arranged on the wheel connector on the external end of the motor shaft by a wheel bolt. A brake floor and a brake clamp support are arranged on an external side end cover of the hub motor. The internal end of the motor shaft is provided with a gap-adjusting nun used for adjusting the gaps of the bearing, namely, used for adjusting the gaps of the wheels in real usage. The invention is applicable to the manufacture of small-sized electric vehicle.
Description
Affiliated technical field
The present invention relates to a kind of automobile-used motor, a kind of specifically external spline shaft hub motor.
Background technology
Adopting wheel hub motor to drive electric automobile, can save engine and complicated transmission mechanism, reduce slippage, improve Energy Efficiency Ratio, is the state-of-the-art type of drive of electric automobile.Wheel hub motor of a great variety, or too simple, poor performance, or complexity and application is poor too technically all seem not mature enough, and rest on the development stage more, enter the practical stage to move towards market seldom.This also is that present electric automobile adopts electrical machinery of active force to add one of reason of transmission system drives more.The advance that wheel hub motor drives has determined that it is must needing of electric automobile development, therefore needs a kind of wheel hub motor simple and practical, dependable performance to address that need.
Summary of the invention
The invention provides a kind of external splines wheel hub motor, is a kind of wheel hub motor of simple and practical, dependable performance.
The present invention includes motor shaft, shell, motor cabinet, the technical scheme that is adopted is: the outer end of motor shaft is provided with external splines, and the outside of shell is equiped with the multipurpose bolt, and outside end cap is installed, outboard end covers and is provided with positioning step, and the both sides of shell are provided with the motor cabinet vertical with motor shaft.
The external splines of described motor shaft outer end is equipped with the wheel connector by hold-down nut, and is equiped with wheel bolt.
The inner of described motor shaft is equiped with transfers the crack nut.
Be provided with cooling water chamber in the described case body, and be provided with the cooling water circulation port.
The flat key mounted connector also can be adopted in the outer end of described motor shaft.
The invention has the beneficial effects as follows: based on traditional threephase asynchronous machine, simple structure is installed easy-to-connect, than the pole changing and the complicated control that are easier to realize to wheel hub motor, perfect heat-dissipating can be installed brake drum, again brake disc can be installed, be a kind of wheel hub motor of dependable performance.
