1. A rack steering system comprising:
a steering gear housing;
a toothed rack that extends through the steering gear housing;
an electric motor coupled to the toothed rack on a thread side of the steering gear housing via a ball screw in order to provide an axial force at the toothed rack; and
two track rod links arranged at the axial ends of the toothed rack,
wherein the steering gear housing is monolithic such that a drive insert opening for arrangement of the electric motor is formed on the thread side of the steering gear housing and a support face is also formed on the thread side for the arrangement and axial support of a separate stop element for one of the two track rod links, and
wherein the support face extends along a part of the circumference of a circular ring, and wherein a drive belt, which is functionally arranged between the electric motor and the ball screw, extends through another part of the circumference of the circular ring in which there is no support face.
