A steering gear apparatus for a steer-by-wire steering system of a motor vehicle has a sliding rod, which has a rack with a toothing, a gear section, which has a worm gear with a worm wheel and a drive pinion extending in an axial direction (A), a motor and a steering angle sensor. The motor is connected here to the drive pinion via the worm gear so as to transmit torque, and the drive pinion is in toothed engagement with the toothing. The steering angle sensor is coupled here to the drive pinion, in particular so as to transmit torque.

Steering gear apparatus for a steer-by-wire steering system

The disclosure relates to an electromechanical rack and pinion steering system for a motor vehicle with an input shaft which is connected to a pinion shaft, wherein a torsion bar is arranged between the input shaft and the pinion shaft, and is directly connected to the input shaft, and the pinion shaft has a steering pinion section for interacting with a rack, and with an electric motor for driving the pinion shaft. The electric motor is connected to the pinion shaft by a transmission. An intermediate shaft piece is arranged between the pinion shaft and the input shaft. The intermediate shaft piece is connected directly to the pinion shaft and connected directly to the torsion bar.
