  • Configuration for preventing contact corrosion in magnesium wheels
    Patent number: 5454628
    Abstract: In order to prevent contact corrosion when a magnesium wheel is fixed to a wheel mount of a motor vehicle, a configuration is provided in which an annular aluminum spacer is inserted between an inner contact surface of the magnesium wheel and the wheel mount in the vicinity of fixing bores. A central centering device in the form of an annular plastic adapter is squeezed into a hub bore of the magnesium wheel in order to cover the radially inner peripheral surface of the spacer and to center the same.
