Up to now steering gears usally utilise worm drives with a maximum ratio of i = 20 : 1, since on higher ratios they would not allow for any backwards rotation. Our new developed involute steering gears achieve higher ratios and can transmit higher torque than comparable worm drives due to an increasement in module. If two input pinions are combined, even higher stresses e.g. for steering heavy duty vehicles can be tolerated. With their compact design, these gears take up smaller installation spaces than so far used worm drives.
