Title:
ELECTROMAGNETIC FRICTION CLUTCH DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/023918
Kind Code:
A1
Abstract:
[Problem] To provide an electromagnetic friction clutch device that makes it possible to achieve size/weight reduction and cost reduction. [Solution] A clutch device 1 transmits torque between a first rotary shaft member 11 and a second rotary shaft member 12 by means of frictional force. The clutch device 1 comprises a first rotary element 2 that cannot rotate relative to the first rotary shaft member 11, a second rotary element 3 that can move in the axial direction but cannot rotate relative to the second rotary shaft member 12, an electromagnetic coil 51 that generates magnetic force that moves the second rotary element 2 in the axial direction relative to the second rotary shaft member 12, and a yoke 52 that supports the electromagnetic coil 51. The second rotary element 3 has a magnetic force reception part 31 that receives the magnetic force generated by the electromagnetic coil 51 and a pressing part 35 that moves in the axial direction with the magnetic force reception part 31 and thereby presses a friction member that is on the first rotary element 2 side and generates frictional force.
