Problems solved by technology

But there are the following disadvantages: the radial and axial dimensions of the stator are too large, the consumables are large, and the cost is high; the starting current is large and the overall efficiency is not high
Although the Chinese patent ZL200420000124.1 solves the above problems, its transmission gear is made of engineering plastics, which has a short service life and cannot be applied to motors above 350W
Due to the particularity and limitations of the hub structure, hard tooth surface transmission cannot overcome the noise problem, so the market is still blank

Abstract

The invention relates to an internal bias hub motor for an electric vehicle. End closures are fixed at the two ends of a housing, the left end closure and the right end closure are sleeve jointed with a front crankshaft and a back crankshaft by a support, the front crankshaft is fixedly connected with the back crankshaft, a stator is fixed in space, the stator is wound with a short-distance threephase winding coil, a circular hole of the stator is sleeve jointed with a rotor, the outer side of the rotor is provided with magnetic pole, the middle part of the rotor is provided with a circular hole which is used for fixing a monodirectional bearing, a middle shaft hole of the monodirectional bearing is sleeve jointed with a rotor shaft which is sleeve jointed on the front crankshaft and the back crankshaft by the support, the right end of the rotor shaft is sleeve jointed with a speed-testing magnetic coil, the left end of the rotor shaft is provided with an external gear, the external gear is externally meshed with an output gear which is sleeve jointed on the front crankshaft by the support, and the left end of the output gear is connected with the front end closure. When in use, the front stator is fixed, the rotor runs at high speed, and power is output by gearing mesh in a deceleration way. When the motor is out of work, the rotor shaft is deviated from the stator so as to prevent the motor from producing magnetic resistance to the external force for remaining the continues rotation. The device has the advantages of low consumption, low noise, free-disassembling maintenance, is effectient and durable, and the like.

Description

technical field [0001] An internally biased in-wheel motor involving motors primarily used in electric vehicles. Background technique [0002] Chinese patent ZL03229449.2 The brushless motor for electric vehicles is a low-speed motor, which has the advantages of simple structure and reliable performance. But there are the following disadvantages: the radial and axial dimensions of the stator are too large, the consumables are large, and the cost is high; the starting current is large, and the overall efficiency is not high. Although the Chinese patent ZL200420000124.1 solves the above problems, its transmission gear is made of engineering plastics, has a short service life, and cannot be applied to motors above 350W. Due to the particularity and limitations of the hub structure, the hard tooth surface transmission cannot overcome the noise problem, so the market is still blank. Contents of the invention [0003] In order to overcome the defects of the prior art, the pres...
