Abstract: A vehicle having a wagon body which is supported on at least one running gear, wherein the wagon body defines a vehicle longitudinal direction, a vehicle transverse direction and a vehicle height direction. The wagon body has a body section and an adjacent head section. The head section has an outer skin and a flow separation unit for reducing sensitivity of the vehicle to crosswind. The flow separation unit comprises a roof-like protrusion formed by the outer skin. The roof-like protrusion has a first roof section, a second roof section, and a ridge section forming a transition between the first roof section and the second roof section. The first roof section and the second roof section run inclined to one another such that, the ridge section forms a flow separation edge for the air flow.

Abstract: A superstructure module of a front-end section of a vehicle is supported on a chassis and includes a flow guiding device. The front-end section forms a leading, free vehicle end during normal operation of the vehicle. The flow guiding device is mounted on a lower side of the superstructure in the longitudinal direction of the vehicle between the free vehicle end and a leading end of a chassis. The flow guiding device influences air flow that flows during operation of the vehicle along the lower side of the superstructure from the free vehicle end to the chassis section. The flow guiding device via a deflection area confers on the air flow, in the region of a flow separation edge at the leading end of the chassis section, a downwardly directed direction of flow.

Abstract: A vehicle component includes first and second surfaces, in a first travel direction of the vehicle. The first surface is exposed to an air flow having a local main flow direction. In a region of a recess on the vehicle, the first surface forms a flow separation edge where the air flow is deflected from the first surface. The recess is delimited by a leading first wall facing the local main flow direction and a trailing second wall. The flow separation edge extends transversely to the local main flow direction over a majority of a transverse dimension of the recess. In the local main flow direction, the second surface borders on the flow separation edge and forms a part of the first wall. The second surface is disposed so that it is inclined like a chamfer about an acute angle of inclination relative to the local main flow direction.

Abstract: A vehicle component includes a surface which, during operation, is exposed to an air flow. The surface includes a separating area where the air flow separates from the surface, and at least one obstructing element associated with the separating area for introducing an obstruction into the air flow. The obstructing element includes at least one guide surface which protrudes into the air flow. The guide surface is inclined relative to the local direction of the main air flow so that it confers on the part of the main air flow that impacts the guide surface a speed component that runs perpendicular to the local direction of the main air flow and induces turbulence in the air flow downstream of the obstructing element.

Abstract: An electronic printed circuit board has a memory module and a contact strip for insertion into another electronic unit. The memory module has at least nine identically designed housing-encapsulated integrated semiconductor memories configured on the printed circuit board. The longer dimension of the housing of one of the semiconductor memories, which is connected as an error correction chip, is oriented perpendicular to the contact strip. The longer dimension of the housings of the other semiconductor memories are oriented parallel to the contact strip. The different orientation of the semiconductor memories makes it possible to reduce the height of the printed circuit board while enabling the rectangular housings to keep the same physical form.
