  • Patent number: 8307939
    Abstract: Disclosed is a steering gear for a power steering system of a vehicle, comprising a component that is mounted axially displaceably in a housing of the steering gear, a tie rod fixed in an articulated manner on at least one axial end of the component by way of a joint, wherein a rotational center of the joint is disposed on a radially directed adapter part laterally offset with respect to a central longitudinal axis of the axially displaceable component, and the adapter part is fixed to the axially displaceable component by way of a shaft-hub connection, which is fastened on the axial end of the axially displaceable component using a nut on an external thread so as to provide a steering gear that has a high-strength, play-free connection between the axially displaceable component thereof and the adapter part, and which is easy to produce, the shaft-hub connection being formed by a play-free, conical serrated connection.
