A steering gear mechanism for motor vehicles may include a steering system housing in which a toothed rack is mounted and displaceable along a longitudinal axis. The toothed rack may be connected to steerable wheels of a motor vehicle and configured to pivot the steerable wheels. The toothed rack can include a first toothed segment that meshes with a first pinion of a pinion shaft, with the pinion shaft being connectable to a steering wheel via an input shaft. The toothed rack may further include a second toothed segment that is situated opposite the first toothed segment with respect to the longitudinal axis and engages with a second pinion. Further, an electric motor can drive the first pinion in a first direction, which by way of direct or indirect coupling causes the second pinion to rotate in a second direction opposite the first direction. The electric motor may drive a gear mechanism shaft that surrounds the pinion shaft and is connected to the pinion shaft by way of a gear mechanism.

Double pinion steering gear with an electric motor

Steering pinions and methods for producing the same are described. The steering pinion has a toothed section for meshing with a gear rack and a connection section for connecting to a steering shaft. The toothed section includes a toothed part and the connection section includes a connection part. The toothed part and the connection part are pressed together in a rotationally fixed manner.

Steering pinion for a steering system and method for the production thereof

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 ().
