Abstract
A disc brake for a commercial vehicle is equipped with a wear adjustment device having two adjustment spindles and a slip clutch actuated when a certain torque is exceeded. The slip clutch is designed such that it can be installed in existing installation spaces. The slip clutch is a safety adapter that is pressed onto the end region of each adjustment spindle via a press fit. In order to achieve the press fit, an inner contour of the safety adapter deviates from a circular shape and that an oversize is selected such that sufficient press forces are generated. The disc brake is particularly suited for heavy trucks and cantilevers.
Claims18
A disc brake having a brake disc, the disc brake comprising:
- a caliper which, in use, straddles the brake disc;
- a brake application device including a wear adjustment device for compensating wear of brake pads, said wear adjustment device including at least one adjusting spindle and an associated slip clutch, the slip clutch being actuated when a given torque is exceeded;
- and
- wherein the slip clutch comprises a safety adapter operatively configured to fit onto an end region of the adjustment spindle via a non-positive connection such that the safety adapter is rotatable with respect to the adjustment spindle when the given torque is exceeded.
A slip clutch for a wear adjustment device of a disc brake for a commercial vehicle, the wear adjustment device including at least one adjustment spindle having a longitudinal axis, the slip clutch comprising:
- a safety adapter operatively configured to fit over an end region of the adjustment spindle with a non-positive connection, a portion of the safety adapter extending from an end face of the adjustment spindle along the longitudinal axis;
- and
- wherein the non-positive connection is operatively configured such that the safety adapter is rotatable with respect to the adjustment spindle when a defined torque is exceeded.
