Title
(DE) KAROSSERIESTRUKTUR FÜR EIN ELEKTRISCH BETRIEBENES FAHRZEUG
(EN) BODY STRUCTURE FOR AN ELECTRICALLY OPERATED VEHICLE
(FR) STRUCTURE DE CARROSSERIE POUR VÉHICULE À PROPULSION ÉLECTRIQUE
Abstract
(DE)
Die Erfindung betrifft eine Karosseriestruktur für ein elektrisch betriebenes Fahrzeug, mit einem in Fahrzeughochrichtung (z) nach fahrzeugunten offenen Montageraum (12) für eine Traktionsbatterie (9), der nach fahrzeugoben von einem, den Fahrzeugboden bildenden Bodenblechteil (10) begrenzt ist, wobei die Traktionsbatterie (9) von fahrzeugunten in den Montageraum (12) eingesetzt ist, und zwar unter Bildung eines freien Montagespalts (∆z) zwischen der Traktionsbatterie-Oberseite (29) und dem Bodenblechteil (10), und wobei im Fahrbetrieb betriebsbedingte Schwingungen sich von ihrem Entstehungsort (VA, HA) in Richtung auf das Bodenblechteil (10) ausbreiten. Erfindungsgemäß ist zur Schall-Dämpfung im Bodenblechteil (10) zumindest ein Dichtstreifen (31, 33, 53) bereitgestellt, der im Montagespalt (∆z) in schallisolierender Druckanlage sowohl mit der Traktionsbatterie-Oberseite (29) als auch mit dem Bodenblechteil (10) ist.
(EN)
The invention relates to a body structure for an electrically operated vehicle, comprising an installation space (12) for a traction battery (9), which installation space is open toward the bottom of the vehicle in the vehicle vertical direction (z) and is delimited toward the top of the vehicle by a floor sheet-metal part (10) forming the vehicle floor, the traction battery (9) being inserted into the installation space (12) from the bottom of the vehicle, namely in such a way that a free installation gap (∆z) is formed between the traction battery top side (29) and the floor sheet-metal part (10), and operation-related vibrations propagating from the production location (VA, HA) thereof toward the floor sheet-metal part (10) during driving. According to the invention, at least one sealing strip (31, 33, 53) is provided for sound damping in the floor sheet-metal part (10), which sealing strip, located in the installation gap (∆z), is in sound-insulating compressive contact both with the traction battery top side (29) and with the floor sheet-metal part (10).
(FR)
L'invention concerne une structure de carrosserie pour un véhicule à propulsion électrique. La structure est pourvue d'un espace de montage (12) qui est ouvert vers le bas du véhicule dans le sens vertical (z) du véhicule pour une batterie de traction (9) et qui est délimité vers le haut du véhicule par une pièce de tôle de fond (10) formant le fond du véhicule, la batterie de traction (9) étant insérée par le bas du véhicule dans l'espace de montage (12), et ce avec formation d'une fente de montage libre (∆z) entre la face supérieure (29) de batterie de traction et la pièce de tôle de fond (10), et les vibrations dues au fonctionnement pendant la marche se propageant de leur lieu d'origine (VA, HA) en direction de la pièce de tôle de fond (10). Selon l'invention, pour l'absorption acoustique dans la pièce de tôle de fond (10), au moins une bande d'étanchéité (31, 33, 53) est fournie, qui, dans la fente de montage (∆z), est en contact avec pression, entraînant une isolation acoustique, aussi bien avec la face supérieure (29) de la batterie de traction qu'avec la pièce de tôle de fond (10).
