The invention relates to a rear suspension for a vehicle such as a bicycle, a motorcycle, or the like, which comprises a chassis referred to as a frame (1), a swinging arm (12) hinged to the frame (1) and supporting the axle (14) of the hub of a driving wheel (15), and a shock absorber (27) having ends respectively connected to the frame (1) and the swinging arm (12), the driving torque being transmitted to the driving wheel by a transmission means, and a crankset housing (16) hinged to the frame (1) by a first hinge means (19) interacting with a second hinge means (22) hinged to the swinging arm (12). The suspension is characterised in that the rotation axis (21) between the first hinge means (19) and the second hinge means (22), the rotation axis (23) between the second hinge means (22) and the swinging arm (12), and the rotation axis (13) of the swinging arm (12) relative to the frame (1) are substantially aligned when the bicycle is in the so-called SAG static balance position.
Image La présente invention concerne une suspension arrière d'un véhicule telle qu'une bicyclette, une moto ou analogue du type comportant un châssis dit cadre (1), un bras oscillant (12) articulé au cadre (1) portant l'axe (14) du moyeu d'une roue motrice (15) et un amortisseur (27) dont les extrémités sont solidaires respectivement du cadre (1) et du bras oscillant (12), le couple moteur étant transmis à la roue motrice par des moyens de transmission, et un boitier de pédalier (16) articulé au cadre (1) par un premier moyen d'articulation (19) coopérant avec un second moyen d'articulation (22) articulé au bras oscillant (12); ladite suspension est remarquable en ce que l'axe de rotation (21) entre le premier (19) et le second (22) moyen d'articulation, l'axe de rotation (23) entre le second moyen d'articulation (22) et le bras oscillant (12), et l'axe de rotation (13) du bras oscillant (12) par rapport au cadre (1) sont sensiblement alignés lorsque la bicyclette est en position d'équilibre statique dit SAG.
