  • Articulated shaft having an axial securing means
    Patent number: 10408276
    Abstract: The articulated shaft has an axial securing means which includes a securing ring which has a spring prestress and acts on the articulated shaft via a connecting device of the articulated shaft to a housing cover of a joint housing. It is provided, in particular, that the housing cover is made of aluminum, on which a bearing disk made from steel lies which supports the prestressed securing ring on the outer side. This arrangement avoids it being possible for the securing ring to bury itself into the housing cover made from aluminum and a greater play being produced and the axial securing action no longer being ensured.
