Abstract

L'invention concerne un appareil de stabilisation (100) et un appareil à cardan (200). L'appareil de stabilisation (100) selon l'invention comprend un premier ensemble bras oscillant (10), un deuxième ensemble bras oscillant (20) et un moyen d'alimentation (30); une première extrémité du deuxième ensemble bras oscillant (20) étant reliée rotative au premier ensemble bras oscillant (10), le deuxième ensemble bras oscillant (20) et le premier ensemble bras oscillant (10) pouvant entraîner le déplacement l'un de l'autre, et une deuxième extrémité du deuxième ensemble bras oscillant (20) étant reliée à un composant (90) à stabiliser; le moyen d'alimentation (30) étant relié à l'une ou l'autre extrémité du premier ensemble bras oscillant (10); le moyen d'alimentation (30) réglant un angle entre le premier ensemble bras oscillant (10) et le deuxième ensemble bras oscillant (20) en fonction d'un écart de décalage du composant (90) à stabiliser dans le sens vertical, de sorte à compenser l'écart de décalage du composant (90) à stabiliser dans le sens vertical, ce qui réduit le degré de gigue vers le haut et vers le bas du composant (90) à stabiliser et améliore la stabilité dudit composant (90) dans le sens vertical.
