Abstract:
1. A disc brake assembly for use with a brake disc, comprising: a caliper operatively configured to be engageable over the brake disc; a brake application device by which a brake lining is pressable against the brake disc through at least one adjusting spindle; a wear adjustment device connected in a rotationally fixed manner to the adjusting spindle, the wear-adjustment device substantially compensating for wear-induced changes in a running clearance between the brake lining and the brake disc; a closure lid that covers the wear-adjustment device and is fastened to the caliper; a reduction gear mechanism connected to the adjusting spindle; a transmitter operatively configured to revolve on a concentric path, the transmitter being connected to the reduction gear mechanism; a contactless lining wear sensor operatively configured to detect a change in angular position of the transmitter, and to provide an output indicative of the change in angular position of the transmitter; wherein the reduction gear mechanism comprises an epicyclic gear; wherein the epicyclic gear comprises a sun wheel and the wear-adjustment device comprises a chain wheel, the sun wheel being fastened in a rotationally fixed manner to the chain wheel; and wherein the sun wheel has locking arms operatively configured to engage in corresponding openings of the chain wheel.
