摘要

New mechanism for concentric expansion brake systems and automatically synchronized regulation applicable to motor vehicles and machinery in general, including each individualized brake in a rotating element shoes whose simultaneous concentric displacement is due to the action of individual oscillating levers oscillating around one end and receiving in their other the thrust of the expander means actuated from the control is linked to the two pads being linked to each other by an effort-balancing device characterized by the fact that each shoe-driving lever has been practiced near the end receiving the action of the expanding means in an elongated eyelet in which a sliding element is slid. Shaft with axis normal to the plane of rotation of the braking element is attached to one end of a connecting rod that is swung in oscillation by its other end in a stump that is in turn joined to the base plate of said rotating element. The contact between the outer cylindrical surface of said trunnion and the interior of the crankpin of the crankpin is based on one or several rollers having a shaft parallel to that of the trunnion and freely housed in roller cavities with ovoidal cross section practical in the surface area of said trunnion so that each trunnion roller to be dragged by the oscillation of the rod around the stump allows free oscillation of the same in one direction but it hinders it in the opposite direction because its rolling on the bottom of the cavity in which the referred ovoidal tracing of this cavity is forced the roller to flush with the plane of opening when rolling towards the widest area to protrude when rolling towards the narrowed area, leaving its projection in the latter case enough to wedge against the hitch surface of the bieladeralizing its oscillation.
