| 摘要 |
The invention concerns a suspension arm for a motor vehicle wheel, said arm being defined in particular by a null torsional plane and being of the type having the shape of a boomerang one of the ends of which (13) is designed to be coupled to a wheel, the other end (12) and the median part (111) of the arm being designed to be pivotably mounted on a cradle integral with said vehicle chassis, said arm also comprising means to be coupled (15) to at least and anti-side-to-side rolling motion bar (2) having a bent part (21) bypassing a steering link rod (3). The invention is characterized in that it comprises a cavity (16) extending from the vicinity of said pivotably mounted end (12) up to the vicinity of the coupling means (15) to said anti-side-to-side rolling motion bar (2), said cavity (16) being arranged to receive at least partly said bent part (21) beneath said null torsional plane when said arm occupies a bouncing position, and it that it further comprises rigidifying means for compensating loss of rigidity induced by the presence of said cavity (16). |
