Abstract
A driving apparatus 100 includes a motor 20 that generates drive power and power transmission units 30, 40, and 50 that transmit drive power of the motor 20 to an output shaft 60. The power transmission units 30, 40, and 50 include a clutch mechanism 30 that switches between a state where the motor 20 and the output shaft 60 are connected and a state where the motor 20 and the output shaft 60 are disconnected, and a brake mechanism 40 that brakes rotation of the output shaft 60, and the clutch mechanism 30 is arranged so as to overlap the brake mechanism 40 in a radial direction.
Claims4
A driving apparatus comprising:
- a motor that generates drive power;
- and
- a power transmission unit that transmits drive power of the motor to an output shaft,
- wherein the power transmission unit includes a clutch mechanism that switches between a state where the motor and the output shaft are connected and a state where the motor and the output shaft are disconnected, a brake mechanism that brakes rotation of the output shaft, and a deceleration mechanism that converts a torque of the motor, and transmits a resultant torque to the output shaft, and
- wherein the deceleration mechanism includes an input shaft that is connected to or disconnected from a motor shaft of the motor by the clutch mechanism,
- the clutch mechanism includes an inner clutch that is directly connected to the motor shaft, an outer clutch that is directly connected to the input shaft, and a sleeve that moves between the inner clutch and the outer clutch,
- the outer clutch overlaps the brake mechanism in the radial direction, and
- the sleeve overlaps the inner clutch and the outer clutch in the radial direction, so as to be movable between the inner clutch and the outer clutch.
