Title:
ELECTROMAGNETIC CLUTCH
Document Type and Number:
WIPO Patent Application WO/2022/057158
Kind Code:
A1
Abstract:
An electromagnetic clutch. The electromagnetic clutch comprises a fixed component, a driven component, and an elastic component (1); the fixed component comprises a magnetic yoke (2), several iron cores (3) are provided on the magnetic yoke (2), coils (4) are provided on the iron cores (3), the driven component comprises an armature disk (5), and several magnetic steels (6) are provided on the armature disk (5); the armature disk (5) is provided corresponding to the magnetic yoke (2), and the iron cores (3) are provided corresponding to the magnetic steels (6); the elastic component (1) is used for keeping the armature disk (5) at a separation position from the magnetic yoke (2); when the coils (4) are energized in the forward direction, the iron cores (3) attract the magnetic steels (6), and the armature disk (5) overcomes an elastic force of the elastic component (1) and moves to an attraction position with the magnetic yoke (2), so that the fixed component is transmittingly connected to the driven component; and when the coils (4) are energized in the backward direction, the iron cores (3) generate an electromagnetic force to reduce an attraction force of the magnetic steels (6), and the elastic force of the elastic component (1) overcomes the attraction force of the magnetic steels (6) to push the armature disk (5) to the separation position from the magnetic yoke (2).
