Title:
POWER TRANSMISSION DEVICE
Document Type and Number:
Japanese Patent JP2007139150
Kind Code:
A
Abstract:

To reduce inverse input torque from an output member, and to reduce driving torque of a motor, in a power transmission device for preventing inverse input applied to the output member from being transmitted to an input member, by transmitting rotation of the input member to the output member with the motor as a driving source.

The input member 3 is rotated by driving of the motor 1, and after moving a clutch disc 13 in the axial direction up to an engagement releasing position by an advancing cam means 18 incorporated between its input member 3 and the clutch disc 13, the output member 7 is rotated together with the clutch disc 13. Rotation of an output gear 7a of the output member 7 is transmitted to a driven gear 10 by reducing a speed, and the inverse input torque transmitted to the output member 7 from the driven gear 10 is reduced. Rotation of a pinion 4 arranged on a rotary shaft 2 of the motor 1 is also transmitted to an input gear 3a of the input member 3 by reducing a speed, and driving torque of the motor 1 is reduced.
