  • Patent number: 10724614
    Abstract: A gear arrangement for transforming a linear force and/or motion into a rotational torque and/or motion and vice versa. The arrangement comprises; a rack (10, 110, 210, 510, 1010, 2010, 3010, 4010) exhibiting a longitudinal axis (A) and at least one toothed side extending parallel to the longitudinal axis of the rack, the rack being reciprocally movable along its longitudinal axis. At least two pinions (20, 120, 220, 520, 1020, 2020, 3020, 4020, 5020) are arranged such that each pinion is rotationally meshing with a toothed side of the rack. Each pinion is fixed to a respective first primary gear (30, 130, 230, 530, 1030, 2030, 3030, 4030, 5030) arranged at a first axial side of the pinion. At least two first primary gears are mechanically connected to a common out- or input shaft (60, 160, 560, 1060), such that the at least two first primary gears transmit torque to or from the first out- or input shaft.
