Abstract:
An electromagnetic clutch structure in a driving force distribution system comprising:a first electromagnetic clutch for transmitting torque from a right output shaft connected to a right driven wheel to a left output shaft connected to a left driven wheel; and a second electromagnetic clutch for transmitting torque from the left output shaft connected to the left driven wheel to the right output shaft connected to the right driven wheel, wherein the selective operation of the first and second electromagnetic clutches transmits torque between the right and left output shafts; wherein each of the first and second electromagnetic clutches comprises a coil; a core housing the coil; an armature arranged to adjoin the core in the lateral direction, the armature having a pressure part; and frictional engagement members arranged on the inside, in the radial direction, of the core; and wherein the frictional engagement members are engaged by pressure of the pressure part of the armature, the pressure part extending further inward in the radial direction than the core.
