Abstract

Official abstract text for this publication.

A load sensitive magnetic clutch device includes: a magnetic pole rotating body having magnetic poles arranged on the circumference thereof and provided with a clutch projection of a claw clutch at an end thereof; a yoke rotating body configured to rotate about an axial center of rotation identical to that of the magnetic pole rotating body; and a high-torque input member configured to rotate about the identical axial center of rotation and having a clutch engaging portion engaging the clutch projection. The clutch projection is formed of a magnetic body. The clutch engaging portion includes a clutch retaining magnetic body configured to attract the clutch projection by a magnetic force. The clutch projection is attracted by the clutch retaining magnetic body by an application of a load torque exceeding a torque which is transferrable between the magnetic pole rotating body and the yoke rotating body.

First claim

Opening claim text (preview).

The invention claimed is: 1. A load sensitive magnetic clutch device, comprising: an output rotating member having a claw clutch projection at an end thereof, and having a magnetic pole rotating body that has magnetic poles arranged on a circumference of the magnetic pole rotating body and that is configured to rotate about an axial center of rotation; a low-torque input member having a yoke rotating body that is configured to rotate about the axial center of rotation of the mag…
