Abstract
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.
Claims17
A steering gear apparatus for a steer-by-wire steering system of a motor vehicle, comprising:
- a sliding rod, which has a rack with a toothing, the sliding rod being free of a mechanical connection to a steering wheel of the motor vehicle,
- a gear section, which has a worm gear with a worm wheel and a drive pinion extending in an axial direction (A),
- a motor
- a steering angle sensor,
- wherein the motor is connected via the worm gear to the drive pinion so as to transmit torque, and the drive pinion is in toothed engagement with the toothing, wherein the steering angle sensor is coupled to the drive pinion so as to transmit torque, the rack being arranged in the axial direction (A) between the steering angle sensor and the worm wheel, and
- a housing formed from a sliding rod housing for the sliding rod, a gear housing for the gear section and a motor housing for the motor, the sliding rod housing and the gear housing being integrally formed, the sliding rod housing having a first opening and the gear housing having a second opening.
A steering gear apparatus for a steer-by-wire steering system of a motor vehicle, the steering gear apparatus comprising:
- a sliding rod including a rack having toothing, the sliding rod being free of a mechanical connection to a steering wheel of the vehicle;
- a gear section including a worm gear having a worm wheel and a drive pinion extending in an axial direction (A);
- a motor connected via the worm gear to the drive pinion so as to transmit torque, wherein the drive pinion is in toothed engagement with the toothing;
- a steering angle sensor configured to detect rotation of the drive pinion attached to the drive pinion to detect the angle of rotation of the drive pinion, the rack being arranged in the axial direction (A) between the steering angle sensor and the worm wheel, and
- a housing formed from a sliding rod housing for the sliding rod, a gear housing for the gear section and a motor housing for the motor, the sliding rod housing and the gear housing being integrally formed, the sliding rod housing having a first opening and the gear housing having a second opening.
