Abstract

La présente invention concerne une poulie suspendue de dispositif de suspension, comprenant : un premier dispositif de suspension pourvu de premières poulies ; et un deuxième dispositif de suspension pourvu de deuxièmes poulies. Le premier dispositif de suspension est relié de manière détachable au deuxième dispositif de suspension. La poulie suspendue de dispositif de suspension de la présente invention a une structure combinée, ce qui simplifie les étapes de démontage et d'assemblage de la poulie suspendue de dispositif de suspension sur un rail de coulissement, évite une structure d'orifice d'accès formée dans le rail de coulissement d'un processus classique, assure la résistance structurelle du rail de coulissement, et obtient une sécurité élevée. La présente invention concerne en outre un ensemble d'amortissement de poulie, comprenant un ensemble tampon et la poulie suspendue de dispositif de suspension. Le premier dispositif de suspension et/ou le deuxième dispositif de suspension sont montés de manière détachable sur l'ensemble tampon. L'ensemble d'amortissement de poulie est pourvu de la poulie suspendue de dispositif de suspension détachable et d'un ensemble roue arrière détachable de sorte que l'ensemble d'amortissement de poulie et le rail de coulissement soient pratiques à assembler et que la faisabilité soit élevée.
