Hub unit for use in electrically movable wheels and vehicle comprising the hub unit |
摘要 |
A hub unit for use in electrically assisted bicycles has an improved effect to radiate heat from a stator. A hub ( 7 ) has inner teeth ( 66 a) meshable with planetary gears ( 65 ) and a fixing support shaft ( 57 ) projecting from opposite ends of the hub and provided fixedly relative to a motor housing ( 5 ). The motor housing ( 5 ) has no cylindrical wall ( 8 ) covering the outer peripheral surface of the stator ( 3 ) but leaves the stator outer peripheral surface exposed to effectively release the heat generated by the windings of the stator.
