  • Differential gear and method of making same
    Patent number: 6656079
    Abstract: A differential gear includes a differential housing consisting of cast iron and a differential crown wheel consisting of case hardened steel. The differential gear, while being of reproducible quality, can be produced simply and cost-effectively. The differential housing has, on the circumference onto which the differential crown wheel is pressed, a bearing shoulder, to which the differential crown wheel is fastened via a nickel-containing welded joint. The composition of the welded joint is influenced by the use of a nickel-containing additional material which is added to the welding melt in the form of an annular foil arranged between the bearing shoulder and the differential crown wheel.
