Electric Power Steering with servo unit on the steering column
The servo unit, together with its electronics, is integrated into the steering column. It connects to the mechanical rack and pinion steering via the intermediate steering shaft. Sensors and torsion bar are located next to the helical gear. The torque generated by the electric motor is converted into an assisting torque by the worm gear and transmitted to the steering shaft. Mechanical steering gear from Bosch provides the ideal platform for this steering variant. High stiffness, good efficiency lightweight construction and low space requirement are the major benefits of this time-tested component, which has been built in the millions. Software developed by Bosch makes it possible to program the electric steering to individual customer needs. In this way, a steering system with the same hardware components can be adapted for different types of applications.
The adaptation to the respective vehicle requirements is ensured by a broadly scalable modular system.
