    • An electromagnetic clutch 1 is disclosed having first and second relative rotary members 3, 5, an electromagnet 11 having a coil 7 and a yoke 9, a rotor 13 placed in close proximity to the electromagnet 11 and permeating magnetic field lines through the yoke 9, a friction clutch 15 operative to transfer drive torque between the first and second relative rotary members 3, 5, and an armature 17 permeating magnetic field lines coming from the rotor 13 for controlling coupling the friction clutch. The rotor 13 includes first and second magnetic members 21, 23 for forming at least one magnetic flux loop 19 and the first and second magnetic members 21, 23 are made of materials different from each other.
    • 公开了具有第一和第二相对旋转构件3,5的电磁离合器1,具有线圈7和磁轭9的电磁体11,靠近电磁体11放置的转子13和通过磁轭9的渗透磁场线, 摩擦离合器15,用于在第一和第二相对旋转构件3,5之间传递驱动力矩,以及来自转子13的用于控制联接摩擦离合器的磁场线的电枢17。 转子13包括用于形成至少一个磁通环19的第一和第二磁性构件21,23,并且第一和第二磁性构件21,23由彼此不同的材料制成。
