ELECTRIC MOTOR-WHEEL Russian patent published in 1997 - IPC

FIELD: mechanical engineering. SUBSTANCE: electric motor-wheel includes electric motor proper, planetary reduction gear, wheel hub and overrunning clutch. Planetary reduction gear is made in form of 2K-V drive consisting of central stem-pinion, involute satellite gears rigidly connected with eccentric shafts with epicycloid satellites on their journals; epicycloid satellites are thrown into engagement with cogwheel. Eccentric shafts are located in carrier to whose ends covers are secured. Covers are provided with trunnions for mounting the electric motor-wheel in fork of load-bearing frame. Cogwheel is mounted on fixed carrier by means of bearings. Part of outer surface of cogwheel is made in form of inner sprocket of overrunning clutch. Rollers are located in seats of control cage of over-running clutch. Control cage is connected with carrier of 2K-V drive mechanism by means of bent tabs. Hub of wheel performs the function of outer holder of overrunning clutch. Bearings are mounted between cogwheel and hub. Central stem pinion is connected with shaft of electric motor rotor; rotor of electric motor is rigidly connected with cover. Shaft of rotor and stem- pinion are mounted in bearings provided in covers. EFFECT: enhanced reliability. 2 dwg
