{{Introduction
|Introduction=<translate>Ce tutoriel vous explique comment réaliser une liaison rotule pour attache une remorque à tout véhicule à mobilité douce. Pour réaliser cette rotule, nous avons récupéré des barres stabilisatrices de voiture, issues du système de suspension. 


La rotule offre une rotation latérale de 360°, une rotation verticale d'environ ± 45°, et un tangage d'environ 20°. Afin de prévoir au cas où un tangage excessif (en cas de chute latérale), on va ajouter une liaison tangage, en venant visser partiellement l'axe de la rotule dans une pièce taraudée pour laisser libre sa rotation.</translate>

{{Tuto Step
|Step_Title=<translate>Trouver les barres stabilisatrices</translate>
|Step_Content=<translate>Les garages automobiles jettent régulièrement ce genre de pièces lors des contrôles techniques, qui sont toujours fonctionnelles pour l'utiliser sur une remorque. Le premier garage que nous avons croisé nous en a donné deux paires. Racontez-leur le projet et iels seront ravi.es de vous aider !


Les barres stabilisatrices sont deux rotules liées par une tige d'acier.</translate>

|Step_Title=<translate>Fabrication de la rotule</translate>
|Step_Content=<translate>*Coupez une paire de rotule en deux, puis taillez le bout de l'axe en cône (pour faciliter le début du filetage).
*Filetez l'axe à l'aide d'une filière à main correspondant à l'axe.
