  • Publication number: 20100288588
    Abstract: Disclosed is a brake device, particularly a disc brake, comprising a caliper, brake drum, or similar, and energy accumulator, especially an accumulator spring. The energy accumulator rests on the caliper or similar while being supported on an abutment by means of a lever arm. A mechanism for transmitting resilient forces between the energy accumulator embodying one spring element is created with the aid of a lever arm via the abutment. The brake device is characterized in that the lever arms can take at least two or more different angular positions relative to each other in relation to the abutment.

  • Publication number: 20100133053
    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.
