Abstract：
 The invention provides a coaxial-split motor circular rim, which comprises a motor, a rim case and a gear transmission system. Wherein, said motor and case are coaxial-split arranged; the central shaft of case is un-rotationally fixed and formed by first semi-shaft and second semi-shaft; the inner end of each two semi-shafts is individually fixed with a disc support, while said two disc supports are fixed; the outer thread of the end of first semi-shaft is connected to the inner thread of the end of motor end-cap to form a connection sheath; the rotational shaft of motor is through the connection shaft and inserted into the central through hole of first semi-shaft to connect one end of universal connection rod; another end of universal connection rod is connected to the input small gear of gear transmission system mounted on the central shaft; and the coaxial-split motor circular rim is mounted between two back horizontal forks of the frame of electric vehicle. The invention has the advantages that the rotor is in suspend unload condition to protect the motor from jounce and outer load, to improve its reliability and service life.
