Abstract: A primary optics for a motorcycle headlamp, wherein the primary optics is a non-imaging primary optics configured to irradiate a segmented light distribution in front of the primary optics, wherein the primary optics includes a plurality of light guiding elements for forming a predetermined segmented light distribution from light of light sources in a main direction. Each light guiding element has a light input surface and a common light output surface, wherein the light guiding elements are arranged in groups, wherein each group includes at least two light guiding elements arranged in juxtaposition along a straight arrangement line orthogonal to the main direction. The light segments generated by the light guiding elements of a group are irradiated in juxtaposition along a straight irradiation line corresponding to and parallel to respective straight arrangement line of the respective group.

Abstract: An illumination device for a motorcycle headlamp, which device is configured to create a segmented light pattern and includes: (i) a plurality of light sources, at least some of which are configured to be activated independently from each other, (ii) a segmented light guide unit, including a plurality of light guide elements and a light homogenization body, and (iii) a projection lens, which is configured to receive the light emitted from the collective light exit surface of the light homogenization body and to project the segmented light pattern, wherein at least some of the light guide elements are part of a first group of light guide elements, said first group having a defined geometric shape of the light entry surface, which is limited by four corners connected by four side edges (left, right, lower, and upper) wherein three of the side edges are straight, and the fourth edge has a rounded protrusion, which increases the light entrance surface, and is either the left or the right edge of the respective li

Abstract: A gear is described for a spur gear stage without play having a hub (1) and a sprocket (2), which is divided along its axis-normal division plane into two partial sprockets, namely into a hub-fixed sprocket part (3) and a sprocket ring (4) which is mounted so it is coaxially rotatable in relation thereto, and which forms springs (6) sectionally enclosing the hub (1) in the circumferential direction, which are integrally connected at their bases (11) to the sprocket ring (4) and which are supported with their free ends (7) protruding toward the hub (1) on stops (8) of the hub (1).
