Title (EN) SUSPENSION GROUP FOR MOTOR VEHICLE, WHEEL GROUP FOR MOTOR VEHICLE, FRONT END OF A MOTOR VEHICLE AND MOTOR VEHICLE THEREOF
(FR) GROUPE DE SUSPENSION POUR VÉHICULE À MOTEUR, GROUPE DE ROUES POUR VÉHICULE À MOTEUR, EXTRÉMITÉ AVANT D'UN VÉHICULE À MOTEUR ET VÉHICULE À MOTEUR ASSOCIÉ
Abstract:
(EN) A suspension group (10) for a motor vehicle (100), wherein said suspension group (10) comprises: a wheel guide (1), which extends along a longitudinal axis (T-T), which comprises a wheel attachment (2) for connection to a rotation pin (3) of a wheel (102,102a) having a rotation axis (R-R) orthogonal to said longitudinal axis (T-T), wherein the wheel guide (1) extends between a first end (1a) and a second end (1b), opposite the first end (1a), a support arm (8) functionally connected to the wheel guide (1) respectively by means of: a first crank (9) rotatably connected at said second end (1b) to the wheel guide (1) and to the support arm (8); a second crank (12) rotatably connected at said first end (1a) to the wheel guide (1) and to the support arm (8), wherein the wheel guide elements (1), the support arm (8) and the first (9) and second (12) crank define a suspension quadrilateral (120), wherein, between at least two of said elements chosen between the wheel guide (1), the support arm (8), the first and the second crank (9,12), a shock absorber group (7) is interconnected in such a way that the shock absorber group (7) varies its extension as the movement of the suspension quadrilateral (120) varies.
(FR) L'invention concerne un groupe de suspension (10) pour un véhicule à moteur (100), ledit groupe de suspension (10) comprenant : - un guide de roue (1), qui s'étend le long d'un axe longitudinal (T-T), qui comprend une fixation de roue (2) destinée à être reliée à une broche de rotation (3) d'une roue (102, 102a) ayant un axe de rotation (R-R) orthogonal audit axe longitudinal (T-T), - le guide de roue (1) s'étendant entre une première extrémité (1a) et une seconde extrémité (1b) opposée à la première extrémité (1a), - un bras de support (8) relié fonctionnellement au guide de roue (1) respectivement au moyen de : - une première bielle (9) reliée de manière rotative au niveau de ladite seconde extrémité (1b) au guide de roue (1) et au bras de support (8); - une seconde bielle (12) reliée de manière rotative au niveau de ladite première extrémité (1a) au guide de roue (1) et au bras de support (8), les éléments de guidage de roue (1), le bras de support (8) et la première (9) et la seconde (12) bielle définissant un quadrilatère de suspension (120), - entre au moins deux éléments choisis parmi le guide de roue (1), le bras de support (8), la première et la seconde bielle (9, 12), un groupe d'absorbeurs de chocs (7) étant interconnecté de sorte que le groupe d'absorbeurs de chocs (7) fasse varier son extension lorsque le mouvement du quadrilatère de suspension (120) varie.
