Abstract

On propose un coussinet pour un véhicule comprenant un manchon interne, un manchon externe et une pluralité de bras élastomères, dans lequel le manchon interne est agencé de manière coaxiale dans le manchon externe, dans lequel le manchon externe a un diamètre interne qui dépasse un diamètre externe du manchon interne afin de former un espace annulaire entre le manchon externe et le manchon interne, dans lequel les bras élastomères sont agencés de manière circonférentielle entre le manchon interne et le manchon externe et sont raccordés à la fois au manchon interne et au manchon externe, et dans lequel au moins un bras élastomère d’un premier groupe de bras élastomères comprend une première dureté Shore, dans lequel au moins un bras élastomère d’un second groupe de bras élastomères comprend une seconde dureté Shore et dans lequel la première dureté Shore et la seconde dureté Shore diffèrent l’une de l’autre.
