The paper presents the geometric and functional characteristics of a gear with ascending variable ratio, based on the gear with rack and geared segment. This gear can be used for the steering boxes of some low power vehicles (without servo-system). The steering gearbox requires an increase (around 30%) in the transmission ratio from the middle position (rectilinear displacement of the vehicle) to the extreme positions (turning/avoiding obstacles/parking).
