Definitions

  • the invention relates to a device for the pivotable connection of an air guiding element, preferably a side air guiding element at the rear of the driver's cab, to a vehicle, preferably in front of a rear cab wall of a commercial vehicle.
  • the air guiding elements are intended to improve the aerodynamics between the tractor unit and the trailer.
  • side air guiding elements are attached to a cabin rear wall and can at least partially close or bridge an area between the cabin and the trailer.
  • the side air guiding elements can generally be arranged to be pivotable about a vertical axis at least on one side (driver's side or passenger's side). This enables access to the rear wall of the cabin, for example to connect and disconnect a media supply for the trailer or to be able to carry out certain maintenance work.
  • pivoting connections for the side air control elements include pivoting outward via a parallelogram, pivoting outward via an axis of rotation and pivoting inward via an axis of rotation.
  • US 8 403 401 B2 discloses an adjustable, air-repellent cover for mounting on a vehicle.
  • Each bracket includes a vehicle bracket section for attachment to the vehicle and a panel bracket section for attaching the panel to the vehicle bracket section.
  • the bracket sections are pivotally coupled to each other, thereby pivotally connecting the panel to the vehicle.
  • the vehicle mounting portion includes a first engagement member and the visor mounting portion includes a second engagement member.
  • the engagement elements are designed in such a way that, when the engagement elements are clamped together, they engage in one another, in order thereby to prevent the cover from pivoting about the axis of rotation and in relation to the vehicle.
  • the invention is based on the object of creating an alternative and / or improved connection for the side air guide elements.
  • the object is achieved by the features of independent claim 1.
  • Advantageous further developments are given in the dependent claims and the description.
  • the invention provides a device for the pivotable connection of a, preferably flat, air guiding element (z. B. spoiler element), preferably a side air guiding element at the rear of the driver's cab, with a vehicle, preferably a rear wall of the driver's cab of a utility vehicle.
  • the device has a swivel hinge which is designed on the one hand for (e.g. direct or indirect) attachment to the air guiding element and on the other hand for (e.g. direct or indirect) attachment to the vehicle.
  • the pivot hinge has a locking mechanism which is designed to automatically lock the pivot hinge when it reaches at least one predetermined pivot position (preferably at least two predetermined pivot positions).
  • the device can offer the advantage that the locking mechanism automatically applies a (z. B. mechanical or magnetic) locking force that holds the pivot hinge in the pivoted position specified before.
  • a swivel mechanism that is as simple as possible for the user can be implemented, which, for example, can do without extra actuation by a lever etc.
  • the automatic locking can contain feedback that is haptically and / or acoustically perceptible for the user, so that the user can be sure that the air guiding element has been locked.
  • the device manages with a few large components and can thus bring a cost and weight advantage over today's series solutions.
  • the locking mechanism is integrated into the swivel hinge. This means, for example, that no separate locking mechanism has to be provided. Construction space can be saved.
  • the locking mechanism is arranged coaxially about a pivot axis of the pivot hinge.
  • the locking mechanism can protect the swivel axis from corrosion.
  • a swivel axis of the swivel hinge is completely encapsulated or sealed, with the locking mechanism particularly preferably partially encapsulating or sealing the swivel axis (e.g. by enveloping a lateral surface of the Swivel axis).
  • the locking mechanism of the swivel hinge can be completely encapsulated or sealed. For example, corrosion can be reduced and maintenance intervals extended.
  • the locking mechanism is designed as a latching mechanism.
  • the locking mechanism is designed to be at least double-acting, so that the pivot hinge can be locked in the at least one predetermined pivot position by at least two locking engagements or movable locking elements. For example, large loads can be withstood in a small installation space.

  • the latching elements are arranged coaxially to one another and / or the latching elements surround a pivot axis of the pivot hinge coaxially and / or the latching elements give a spring, preferably a helical spring (e.g. helical compression spring), coaxially. It is also possible that a socket area of the swivel hinge, preferably a swivel arm of the swivel hinge, surrounds the latching elements coaxially. For example, the installation space required can be reduced and / or a protective encapsulation can be contributed.
  • the second locking element and the fourth locking element are elastically supported against one another, preferably by means of a spring.

Abstract

L'invention concerne, entre autres, un dispositif conçu pour connecter de manière pivotante un élément déflecteur d'air (16), de préférence un élément déflecteur d'air latéral situé face arrière de la cabine de conducteur, à un véhicule (10), de préférence à une paroi arrière de cabine de conducteur d'un véhicule utilitaire. Ce dispositif comprend une charnière de pivotement (22) conçue pour être reliée d'un côté à l'élément déflecteur d'air (16) et de l'autre côté au véhicule (10). Cette charnière de pivotement (22) comprend un mécanisme d'arrêt (32) conçu pour arrêter la charnière de pivotement (22) automatiquement lorsqu'au moins une position de pivotement prédéterminée est atteinte.
