ABSTRACT:
A self-contained brake actuator assembly including a cylinder, an actuated piston within the cylinder, an actuating piston, a rotatable threaded shaft for translating rotational motion to axial motion operatively connected to the actuating piston, a fluid-filled chamber between the actuated and actuating pistons defining a fluid link therebetween whereby axial movement of the actuating piston causes axial movement of the actuated piston, wear take-up and anti-drag structure for permitting substantially free forward movement of the actuated piston in unison with the actuating piston and for limiting retraction of the actuated piston to a predetermined maximum distance, and a fluid supply contained within the cylinder for supplying additional fluid to the chamber in response to retraction of the actuating piston a distance greater than the predetermined maximum for the actuated piston to thereby accommodate the increase in volume of the chamber occasioned by the resultant separation of the pistons.
The invention further includes stop members for preventing transverse deflection of the brake shoe when the brakes are applied, structure for permitting compound motion of the brake shoe to accommodate uneven brake pad wear between the inside and outside brake pads in an assembly including a cone disc, and structure for attaching the brake pads to the brake shoe to increase resistance to shear forces so that an inexpensive adhesive may be used to bond the pads to the shoes.
