ABSTRACT:
An automatic adjusting device for a disc brake having a brake piston displaceably arranged in a brake cylinder for the purpose of actuation of a brake shoe. This device which is actuatable by means of a hydraulic and a mechanical actuating device, includes an adjusting member between the brake piston and the mechanic actuating device which member is composed of two adjusting elements, an adjusting spindle and adjusting nut interconnected via a thread without self-locking engagement. It further comprises a friction clutch having conical friction surfaces for fixing one of the adjusting elements in position on mechanical actuation. One of the conical friction surfaces is on one of the adjusting elements and the other friction surface is on a mechanically actuatable clamping member. It also comprises a bowl-type (cup-shaped) spring retainer which is secured to the brake housing by means of an accommodation sleeve. In order to render manufacture as simple and cost-effective as possible, the accommodation sleeve is made from a straight tubular member which is pressed into a corresponding bore in the brake housing.
