(FR) AVANT-TRAIN POUR VÉHICULES À MOTEUR À DEUX ROUES DIRECTRICES AVANT, AVEC ENSEMBLE CENTRAL ABSORBEUR DE CHOCS, ET VÉHICULE À MOTEUR COMPRENANT LEDIT AVANT-TRAIN
Abstract
(EN)
The forecarriage comprises a forecarriage frame (111) and a four-bar linkage (17) connected to the forecarriage frame (111). The four-bar linkage supports, by means of a first supporting member (31') and a second supporting member (31"), a first front wheel (13') and a second front wheel (13") respectively. The forecarriage also comprises a steering column (5) rotatingly housed in a steering column tube (3) connected to the forecarriage frame. The steering column is connected to a connecting bar (41) which connects the first supporting member (31') and the second supporting member (31") to one another. There is also provided a shock absorber assembly (51) interconnected between the steering column (5) and the first connecting bar (41).
(FR)
L'avant-train comprend un cadre (111) et une tringlerie à quatre barres (17) reliée au cadre d'avant-train (111). La tringlerie à quatre barres supporte, au moyen d'un premier élément de support (31') et d'un second élément de support (31"), une première roue avant (13') et une seconde roue avant (13") respectivement. L'avant-train comprend également une colonne de direction (5) logée rotative dans un tube (3) correspondant relié au cadre d'avant-train. La colonne de direction est reliée à une barre de liaison (41) qui relie le premier élément de support (31') et le second élément de support (31 ") l'un à l'autre. L'invention concerne également un ensemble amortisseur de chocs (51) interconnecté entre la colonne de direction (5) et la première barre de liaison (41).
