  • the brakes are braked by supplying energy fluid to the stock cavity - Cylinder 16 - 14.

Abstract

L'invention se rapporte au domaine du génie mécanique et peut être utilisée dans les freins à serrage de véhicules de transport. Le modèle d'utilité consiste essentiellement en un étrier de frein relié par charnière à une base le long d'un axe perpendiculaire à l'axe de rotation de l'objet en rotation. La semelle de frein mobile est connectée par charnière à une tige de piston entrant en interaction avec un guide de dispositif se présentant sous forme d'un premier épaulement, tandis que la semelle de frein immobile est connectée par charnière directement à un second épaulement. Le résultat technique consiste en une plus grande fiabilité et une réduction des pertes énergétiques du frein.
