Abstract

Dispositivo di regolazione automatica per freni. "Simplex" e "Duo-Duplex", con estremità di collegamento mobili contrastate da una molla; con una vite di regolazione associata alla prima di esse ed un dado ivi impegnato, tramite la cui rotazione si imposta la distanza fra le estremità; con una boccola girevole collegata alla seconda estremità, girevole in relazione allo spostamento assiale della seconda estremità rispetto alla prima; con una bussola intermedia installata sul perimetro esterno del dado di regolazione; con un giunto di azionamento mono-direzionale, installato fra boccola e bussola intermedia; e con un dispositivo d'arresto installato fra bussola intermedia e dado di regolazione, che consente una loro rotazione relativa in relazione ad una sollecitazione sul dado di regolazione tendente ad avvicinare le estremità di collegamento, costituito da un elemento elastico fissato alla bussola intermedia e provvisto di zone di elasticità bloccate entro corrispondenti rientranze del dado di regolazione.Automatic adjustment device for brakes. "Simplex" and "Duo-Duplex", with mobile connection ends contrasted by a spring; with an adjustment screw associated with the first of them and a nut engaged therein, by means of which rotation the distance between the ends is set; with a rotating bushing connected to the second end, rotating in relation to the axial displacement of the second end with respect to the first; with an intermediate bush installed on the external perimeter of the adjustment nut; with a mono-directional actuation joint, installed between bushing and intermediate bushing; and with a stop device installed between the intermediate bush and adjustment nut, which allows their relative rotation in relation to a stress on the adjustment nut tending to approach the connection ends, consisting of an elastic element fixed to the intermediate bush and provided of elasticity zones blocked within corresponding recesses of the adjustment nut.
