IN-WHEEL MOTOR INSTALLED IN A SPEED REDUCER FOR A VEHICLE CAPABLE OF INCREASING THE DEGREE OF FREEDOM FOR DESIGN

摘要

PURPOSE: An in-wheel motor installed in a speed reducer for a vehicle is provided to increase power efficiency by manufacturing a speed reducer having a high deceleration ratio while minimizing the size of an in-wheel motor.;CONSTITUTION: An in-wheel motor(100) installed in a speed reducer for a vehicle comprises a drive motor(10), a first rotary shaft(20), a second rotary shaft(30), and a reducer(40). The drive motor supplies torque to a vehicle wheel(11). The first rotary shaft is rotated by being connected to the driving shaft of a drive motor. The second rotary shaft transfers torque to a vehicle wheel by receiving the torque from the first rotary shaft. The speed reducer comprises a drive gear(41) and an inner gear(43). The drive gear is mounted in the first rotary shaft. The inner gear transfers torque to the second rotary shaft.;COPYRIGHT KIPO 2013
