The invention relates to a motor vehicle steering system, comprising a steering housing () in which a steering rack () is mounted in a longitudinally displaceable manner and is connected to tie rods () to swivel steerable wheels (), the steering rack () being provided with a first toothed segment () which meshes with a first steering pinion () and the steering pinion () being connected to a steering wheel () for conjoint rotation by a steering shaft (), the steering rack () having a second toothed segment () which is opposite the first toothed segment () relative to the longitudinal axis of the steering rack (), and that a second steering pinion () is provided which meshes with the second toothed segment ().

Double pinion steering gear

A toothed rack or threaded rod, in particular for a steering mechanism for a motor vehicle, includes a first rod-shaped part which, as a function element of the toothed rack or threaded rod, includes at least one element for the conversion of a rotational movement into a translational movement, in particular a toothing and/or a threading for the engagement of a threaded nut or of a threaded drive, and a second rod-shaped part which is connected with the first rod-shaped part. The connection of the first with the second rod-shaped part takes place via a separate connection part which includes first and second connection pins, of which the first connection pin is held by press fit in the hollow volume opening out at the connection end of the first rod-shaped part and the second connection pin is held by press fit in the hollow volume opening out at the connection end of the second rod-shaped part. A section of the connection part located between the first and the second connection pin has at least over a region of its circumference a greater radial dimension than the first and the second rod-shaped part in the corresponding circumferential region.
