Abstract

Two-body damper vehicle characterised in that it consists of a tractor body (prime mover) 1 equipped with a vertical mounting plate 2 on which is fixed the damper body 3 itself carried by an axle 4. The damper body consists of changeable replaceable energy absorbers joined together, the position of the axle 4 being adjustable.

Description

DESCRIPTION
La présente invention concerne un véhicule destiné à atténuer les chocs provoqués par d'autres engins roulants qui viennent à tamponner par l'arrière le véhicule destiné à assurer par exemple la signalisation d'un chantier mobile ou fixe.DESCRIPTION
The present invention relates to a vehicle intended to attenuate the shocks caused by other rolling vehicles which come to buffer the rear of the vehicle intended to ensure, for example, the signaling of a mobile or fixed construction site.

Traditionnellement ces chantiers sont protégés par des véhicules automobiles classiques portant une signalisation spécifique, les conducteurs de ces véhicules sont alors soumis à des risques élevés d'accident provoquant des lésions importantes sur les occupants des véhicules tamponneurs et tamponnés et sur leur materiel. Le dispositif selon l'invention permettent de remédier à ces inconvénients. Le dispositif est représenté sur la figure (1). Traditionally these sites are protected by conventional motor vehicles carrying specific signage, the drivers of these vehicles are then subject to high risks of accident causing significant damage to the occupants of bumper and buffered vehicles and their equipment. The device according to the invention overcomes these drawbacks. The device is shown in Figure (1).

Il comporte un corps tracteur < i) équipé, préférentiellement d'un seul essieu directeur et moteur, d'une platine verticale (2! faisant office de chassis qui peut être la coque elle-meme de la cabine suffisamment rigide pour solidariser selon un procédé connu par exemple par boulonnage, rivetage, collage etc ... un corps atténuateur constitué de modules déformables sous contraintes, par exemple, nid d'abeilles, mousses semi-rigide, métal déployé ..., de forme géométriques simples au besoin autobloquantes.  It comprises a tractor body <i) equipped, preferably with a single steering and driving axle, with a vertical plate (2! Acting as a chassis which can be the hull itself of the cabin sufficiently rigid to be joined according to a process known for example by bolting, riveting, bonding, etc., an attenuating body made up of deformable modules under stresses, for example, honeycomb, semi-rigid foam, expanded metal, etc., of simple geometric shape if necessary, self-locking.

Ces modules sont assemblés par des moyens classiques. L'ensemble des modules constitue un caisson qui est solidarisé à un essieu tracté selon des procédés connus ce qui remplace le chassis et constitue un ensemble rigide, mais déformable sous les chocs. Les modules déformés pouvant être remplacés économiquement selon l'ampleur des dégâts.These modules are assembled by conventional means. The set of modules constitutes a box which is secured to a towed axle according to known methods which replaces the chassis and constitutes a rigid assembly, but deformable under impact. The deformed modules can be replaced economically depending on the extent of the damage.

Une autre caractéristique très intéressante de l'invention est que les modules peuvent être remplacés par d'autres différents de par leurs caractéristiques géométriques et selon leur capacité d'absorption, ce qui permettra de tester différents types de modules et différentes dispositions de façon économique permettant d'aboutir rapidement aux emplois les plus rationnels. Another very interesting characteristic of the invention is that the modules can be replaced by others different by their geometrical characteristics and according to their absorption capacity, which will make it possible to test different types of modules and different arrangements economically allowing to quickly get the most rational jobs.

La position de l'essieu est adaptable, plus en avant ou plus en arrière une disposition particulière est de le solidariser sur une platine. à l'extrémité ou en position intermédiaire du corps de 1 'atténuateur.  The position of the axle is adaptable, further forward or further back a particular arrangement is to secure it on a plate. at the end or in the intermediate position of the body of the attenuator.
