Abstract: The invention relates to an adjustment mechanism that includes a set ring gears which are arranged coaxially towards a central axis and which each include a cylindrical toothing system, two eccentric wheels with beveloid gears which mesh with the cylindrical toothing systems of the ring gears, eccentric axes which are inclined at an angle towards the central axis, and a central shaft that is driven by a drive shaft onto which the eccentric wheels are mounted. The set of ring gears include a center ring gear that is circulating and two outer neighboring ring gears which are solidly fixed.

Abstract: An arrangement for shifting a gearbox. The arrangement having first and second transmission components (14) and an axially movable shifting sleeve (17) such that the shifting sleeve (17) and the second transmission component (14) each have respective drive teeth (14a, 17a) that can be brought into engagement with one another. The drive teeth are in the form of beveloid teeth (14a, 17a).

Abstract: A swash plate mechanism consists of a drive element that can be rotated about a main axis, a transmission element that can be rotated about a swash plate axis, the swash plate axis intersecting the main axis at a swash plate angle and rotating about the main axis together with the drive element, a power take-off element and a supporting element. A first coupler is arranged between the transmission element and the power take-off element and a second coupler is arranged between the transmission element and the supporting element, with at least one of the two couplers being a pair of teeth, and with the teeth of the pairs of teeth serving as coupling means being designed as spur toothing.

Abstract: A swash plate mechanism (200) consists of a drive element (210) that can be rotated about a main axis (250), a transmission element (220) that can be rotated about a swash plate axis (260), the swash plate axis intersecting the main axis at a swash plate angle (a) and rotating about the main axis together with the drive element, a power take-off element (230) and a supporting element (240). A first coupling means is arranged between the transmission element (220) and the power take-off element (230) and a second coupling means is arranged between the transmission element and the supporting element, with at least one of the two coupling means being a pair of teeth, and with the teeth (271, 272, 273, 274) of the pairs of teeth serving as coupling means being designed as spur toothing.

Abstract: A superposition gear unit for a steering system of a motor vehicle. The gear unit comprising a drive input shaft (1) and a drive output shaft (2) which each carry gearwheels (3, 4; 3?, 4?) at their ends facing toward one another such that rotational movement of the input shaft (1) can be transmitted by the gearwheel (3; 3?), on the drive input side, to the gearwheel (4; 4?), on the drive output side, via external planetary gears (5a-5c; 5a?-5c?) which are mounted on a planetary gear carrier (6). The rotational movement of the input shaft (1) can be overlaid with additional rotation movement by intentional rotation of the planetary carrier (6) relative to the input shaft (1). The input-side gearwheel (3; 3?) and the output-side gearwheel (4; 4?) are, in each case, made as conical involute gearwheels.
