Abstract
Ein Strömlinienformiger Aufbau (2) am Heck eines LKW (1), einen Busses oder einen Wohnmobils dadurch gekennzeichnet, dass: es es keine feste sondern eine aufblasbare Konstruktion ist; und dass es auf einer zusätzlichen Platte (3) auf der Hinterwand des Fahrzeugs montiert ist, die auf Scharnieren montiert ist, so dass die Konstruktion zur Seite geschwenkt werden kann um den Zugang zum Heck (4) des Autos zu ermöglichen; und dass die aufblassbare Konstruktion mittels Luftdruck rausgefahren wird wenn sie in Betrieb genommen wird; und dass die aufblassbare Konstrunktion mittels Vakuum stabil und fest eingefahren wird wenn sie nicht benutzt wird; und dass die aufblassbare Konstruktion aus mehreren Kammern (5) besteht, die getrennt, nach einander mit Druck oder Vakuum gefüllt werden um ein geordnetes und sicheres raus-, und reinfahren zu ermöglichen; und dass die Konstruktion mittels Pumpen oder Fahrwind, oder Kombination von beiden...A streamlined structure (2) at the rear of a truck (1), a bus or a mobile home, characterized in that: it is not a fixed but an inflatable structure; and in that it is mounted on an additional plate (3) on the rear wall of the vehicle, which is mounted on hinges so that the structure can be pivoted to the side to allow access to the rear (4) of the car; and that the inflatable structure is deployed by means of air pressure when it is put into operation; and that the inflatable construction is stably and firmly retracted by vacuum when not in use; and that the inflatable construction consists of several chambers (5) which are separately filled with pressure or vacuum one after the other in order to enable an orderly and safe drive out and in; and that the construction by means of pumps or driving wind, or a combination of both ...
Description
Das Technische GebietThe technical area
Fahrzeugbau, Autobau. Teile der Fahrzeugtechnik. Maßnahmen zu Optimierung der Aerodynamik der Fahrzeuge, insbesondere großen Fahrzeugen (keine PKW's)Vehicle construction, car construction. Parts of the vehicle technology. Measures to optimize the aerodynamics of vehicles, especially large vehicles (no cars)
Der bisherige Stand der TechnikThe current state of the art
Es gibt eine Vielzahl von Lösungen die die Aerodynamik der großen Fahrzeugen verbessern sollen. Bekannt sind Dachspoiler an LKW's die den Übergang von der Kabinne zum Laderraum aerodynamisch optimieren oder moderne Busse wo der Fahrer sehr niedrig sitzt und die obere Vorderwand des Fahrzeug sehr schräg nach hinten geneigt ist. Es gibt auch experimentelle Lösungen, ein LKW mit einem Strömlinienformigen Heck auszustatten. Dies ist jedoch aus praktischen Gründen in dem Alltagsbetrieb kaum anwendbar.There are a variety of solutions to improve the aerodynamics of large vehicles. Roof spoilers are known on trucks that aerodynamically optimize the transition from the cabins to the load compartment or modern buses where the driver is sitting very low and the upper front wall of the vehicle is inclined very obliquely backwards. There are also experimental solutions to equip a truck with a streamlined stern. However, for practical reasons, this is hardly applicable in everyday use.
Hintergrund und Darstellung der ErfindungBackground and illustration of the invention
Die Aufgabe besteht darin, einen stromlinienformigen Aufbau für die Hinterwand eines LKW zu entwerfen, der die praktische Nutzung des LKW nicht behindert oder erschwert.
- – Der Zugang zu der Hintertür des Laderaums soll nicht eingeschränkt werden.
- – Die Konstruktion die zwangsläufig die Fahrzeugslänge erheblich vergrössern würde sollte auch nach Bedarf ”einfahrbar” sein, so dass das Fahrzeug die ursprüngliche Länge hat. Bei den Stadtfahrten oder beim Manövrieren braucht man kein überlanges Aerodynamisches Teil
- - The access to the back door of the hold should not be restricted.
- - The construction would inevitably increase the vehicle length significantly should also be "retractable" as needed, so that the vehicle has the original length. For city driving or maneuvering you do not need a super long aerodynamic part
Die hier vorgestellte Konstruktion erfüllt diese Anforderungen. Sie wird an einer Platte (
Der stromlinienformige Körper (
Die unstabile Phase beim ausfahren oder reinfahren des Körpers wird dadurch gemildert, dass der Körper aus mehreren Kammern besteht die unabhängig voreinander mit Druck oder Unterdruck versorgt werden. So kann z. B. beim reinfahren schon die Außenhüle des Körpers ”eingesaugt” werden während innen ein Kern noch hart unter Druck steht und verhindert, dass der Stoff einfach auf den Boden hinter dem Fahrzeug abfallt oder (im Fahrt) hinter dem Fahrzeug flattert. Alternativ kann der Körper so aufgebaut sein, dass die Kammer nacheinander folgen, so dass der Körper ”scheibenweise” reingefahren wird (
Ausführungsbeispielembodiment
An der Hinterwand des LKW's (
An dem Rahmen mit Platte wird ein ”aerodynamisches Weichkörper” (
Der Weichkörper wird mit Luftdruck gefüllt beim rausfahren und mit Unterdruck wieder reingefahren (und mit Vakuum fest am Fahrzeugheck gehalten).The soft body is filled with air pressure when driving out and back in with negative pressure (and held firmly with vacuum at the rear of the vehicle).
Die einzelnen Kammern des Weichkörpers werden mit Pumpen oder Fahrwind oder Kombination von beiden nit Luft gefüllt oder wieder entleert.The individual chambers of the soft body are filled with pumps or driving wind or combination of both nit air or emptied again.
Am Ende des Weichkörpers werden zusätzliche Rücklichter des Fahrzeugs montiert. Es empfehlt sich eine robuste, stoßunempfindliche Ausführung, z. B. mit LED als Leuchtmittel.At the end of the soft body additional taillights of the vehicle are mounted. It recommends a robust, shock-resistant design, z. B. with LED as the light source.
