Abstract
A drive plate of an electromagnetic-fan clutch comprises: a body of the drive plate provided with magnetic-insulation air holes, connection ribs, and magnetic conductive layers. The magnetic-insulation air holes and the magnetic conductive layers are arranged alternatively along a radial direction of the body of the drive plate. A friction-increasing groove is opened on the magnetic conductive layer. The thickness of the magnetic insulation air holes and the thickness of the connection ribs are less than the thickness of the magnetic conductive layers. Six connection ribs are distributed uniformly between the magnetic conductive layers, and the connection ribs at two sides of the magnetic conductive layer are distributed along the radial direction of the body of the drive plate at an interval of 30 degrees. A drive plate through hole is opened in the body of the drive plate, and accommodation walls are disposed on the magnetic conductive layers.
