Abstract

Est décrit un système de freinage comportant un frein qui est soumis à l'action d'un ressort accumulateur et qui est boulonné sur un bloc d'engrenage. L'inconvénient des dispositifs connus est que le ressort accumulateur nécessaire pour actionner le frein est relié directement au carter et éventuellement à une bande de serrage supplémentaire. Par suite, le système de freinage est difficile à réaliser et le ressort accumulateur est soumis, par l'intermédiaire du carter, à des chocs et à des oscillations considérables. L'objet de la présente invention est de simplifier et d'améliorer la conception du système de freinage et de faciliter son montage. Ce but est atteint dans le principe grâce au fait que le carter (14) du ressort accumulateur est combiné avec le carter (37) du frein. Des perfectionnements avantageux concernent le raccordement direct par liaison de force entre le poussoir (30) du ressort accumulateur (14) et le disque de butée à billes (36) d'un frein à disque plein, qui fait partie du frein (2), le refroidissement et le renforcement améliorés du carter de frein au moyen de nervures radiales,la position spéciale du ressort accumulateur (14) par rapport au carter de frein (37), ainsi que la configuration du frein de blocage (14).
