Abstract
A steering gear comprises a helical pinion and a helical gear which are mounted in the gear housing and driven by an electric motor, wherein a control unit and a sensor system connected thereto are also disposed in or on the steering gear so as to detect and control the rotor position and/or rotation of the rotor of the electric motor. A section of the shaft of the worm located on the drive side extends in the axial direction and protrudes from the gear housing, wherein the protruding end of the section on the drive side is designed as a rotor shaft of the electric motor, and the control unit and/or the sensor system are disposed on the gear housing. The control unit and the sensor system are preferably disposed on differing sections of the gear housing. This allows a very compact, cost-saving and flexible implementation of the design.
