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

An electrically driven rack and pinion steering system of a motor vehicle has an axially displaceably mounted rack which transmits a steering movement for steered wheels of the motor vehicle, has an electric drive which provides a steering force and interacts with the rack, and has a housing which receives the rack and a drive element of the drive. The drive element is in engagement with a toothing system of the rack. A bearing assembly is arranged on a section of the rack without a toothing system axially on each side of the drive element, with a carrier cylinder, on the outer shell face of which an outer contact seal is arranged and on the inner shell face of which an inner contact seal is arranged, the contact seals sealing the housing with respect to the rack.

Electrically driven rack and pinion steering system of a motor vehicle

A steering system () for a motor vehicle, which steering system () is configured as a steer-by-wire steering system, comprises a rack (), an electric drive () for the longitudinal displacement of the rack (), and a rotatably mounted supporting element () which is spaced apart from the electric drive () along the longitudinal axis of the rack (), and the rotatably mounted supporting element () being in toothed engagement with the rack ().
