Hand-driven, wheeled carrier deceleration device and hand-driven, wheeled carrier having the same
A hand-driven, wheeled carrier deceleration device, applied to an axle of a hand-driven, wheeled carrier, is introduced and has a wheel, driven gear, reluctance motor and resistive component. The wheel, pivotally disposed at the axle, has a drive gear which rotates together with the wheel. The driven gear, disposed beside the axle, meshing with and driven by the drive gear, has a connection portion. The reluctance motor, connected to the connection portion and driven by the driven gear, has permanent magnets and metal elements. The metal elements and permanent magnets are arranged annularly. The metal elements rotate relative to the permanent magnets. The resistive component electrically connects to the permanent magnets. Therefore, a driving force exerted on the hand-driven, wheeled carrier is partially offset by reluctance to effectively slow down the hand-driven, wheeled carrier.
