APPARATUS FOR WHEEL DIRECT DRIVE

摘要

PURPOSE: A wheel direct driving device for directly driving a rim of the wheel is provided to minimize the installation space by reducing the mechanical power loss. CONSTITUTION: A wheel direct driving device for directly driving a rim of the wheel comprises a motor housing(110), motors(120,130) and a reducer. The motor installs inside the motor housing. The reducer is connected to the motor. The motor housing, the motor and the reducer install inside a rim(190) of the wheel. A driving shaft has an eccentric shaft(142) and is connected in the rotation of the motor. A center hole is inserted to a cycloidal gear. The cycloidal gear has a plurality of penetration holes. A cycloidal tooth is formed on the outer circumference of the cycloidal gear. The cycloidal gear installs to the eccentric shaft. A plurality of guide pins is contacted with the outer circumference of the cycloidal gear. The connection pin is inserted into the penetration hole of the cycloidal gear. A reducer output unit is fixed with the connection pin.
