  • Patent number: 10421481
    Abstract: A utility vehicle steering system includes a steering gear for transmitting a manual torque from a steering wheel to a steering drop arm. An electric motor provides an auxiliary torque for the steering boost, which is provided exclusively electrically over the entire operating range of the steering system. An input shaft and an output shaft have axes of rotation that are skewed with respect to each other. A first gear device couples the input shaft to the output shaft. A second gear device has the electric motor connected to the input side and has at least one speed-reduction gear stage in the form of a coaxial gear with a high transmission ratio. The output side of the second gear device is coupled to the output shaft and its speed reduction gear stage, a coaxial gear with a high transmission ratio, is coaxial with the output shaft.
