Disc brake with a reset device and motor vehicle with a disc brake

1. A disc brake ( 1 ) for motor vehicles, comprising at least two brake pads ( 25 , 26 ), an application unit ( 4 ) having a setting spindle ( 5 ) arranged axially in the direction of the brake pads ( 25 , 26 ), and a resetting device ( 7 ) for central adjustment of the setting spindle ( 5 ) after reaching a degree of wear of the brake pads ( 25 , 26 ), the resetting device ( 7 ) having a housing ( 8 ), a sensor ( 9 ) and a central resetting shaft ( 10 ), wherein the resetting device ( 7 ) has an adapter ( 11 ) with a decentral output ( 12 );

wherein the adapter ( 11 ) has a cover ( 13 ) and a chain drive ( 14 ), the chain drive ( 14 ) being configured to transmit an actuating movement from the decentral output ( 12 ) to the central resetting shaft ( 10 );

wherein the central resetting shaft is centrally located on the disc brake;

wherein the adapter is selectively removable from the housing, to provide for direct central actuation of the resetting shaft, and is selectively receivable on the housing, to provide for decentral actuation of the resetting shaft via the decentral output;

wherein the chain drive is fixed to the cover when the adapter is removed from the housing and the chain drive and the cover define a unit, and wherein the chain drive is retained on the housing when the adapter is received on the housing.

2. The disc brake ( 1 ) according to claim 1 , wherein the adapter ( 11 ) is arranged on the resetting device ( 7 ) by a plug connection ( 16 ) or an adhesive connection.

3. The disc brake ( 1 ) according to claim 1 , wherein the housing ( 8 ) has, on a side of the housing ( 8 ) opposed to the sensor ( 9 ), a groove ( 17 ) for receiving the adapter ( 11 ).

4. The disc brake ( 1 ) according to claim 1 , wherein the decentral output ( 12 ) is a casting shaped as a hexagon for receiving a tool.

5. The disc brake ( 1 ) according to claim 1 , wherein the cover ( 13 ) is a plastic part or a metal part and has an opening ( 19 ), through which the decentral output ( 12 ) extends.

6. A motor vehicle comprising a disc brake ( 1 ) according to claim 1 .

7. The disc brake according to claim 1 , wherein the cover and chain drive extend linearly in a lateral and downward direction from the resetting shaft to the decentral output.

8. A disc brake ( 1 ) for motor vehicles, comprising at least two brake pads ( 25 , 26 ), an application unit ( 4 ) having a setting spindle ( 5 ) arranged axially in the direction of the brake pads ( 25 , 26 ), and a resetting device ( 7 ) for central adjustment of the setting spindle ( 5 ) after reaching a degree of wear of the brake pads ( 25 , 26 ), the resetting device ( 7 ) having a housing ( 8 ), a sensor ( 9 ) and a resetting shaft ( 10 ), wherein the resetting device ( 7 ) has an adapter ( 11 ) with a decentral output ( 12 );

wherein the adapter ( 11 ) has a cover ( 13 ) and a chain drive ( 14 ), the chain drive ( 14 ) being configured to transmit an actuating movement from the decentral output ( 12 ) to the resetting shaft ( 10 );

wherein the chain drive ( 14 ) is affixed to the cover ( 13 ) with a fastener ( 15 ) in a force-fitting or positively locking manner.

9. A disc brake ( 1 ) for motor vehicles, comprising at least two brake pads ( 25 , 26 ), an application unit ( 4 ) having a setting spindle ( 5 ) arranged axially in the direction of the brake pads ( 25 , 26 ), and a resetting device ( 7 ) for central adjustment of the setting spindle ( 5 ) after reaching a degree of wear of the brake pads ( 25 , 26 ), the resetting device ( 7 ) having a housing ( 8 ), a sensor ( 9 ) and a resetting shaft ( 10 ), wherein the resetting device ( 7 ) has an adapter ( 11 ) with a decentral output ( 12 );

wherein the adapter ( 11 ) has a cover ( 13 ) and a chain drive ( 14 ), the chain drive ( 14 ) being configured to transmit an actuating movement from the decentral output ( 12 ) to the resetting shaft ( 10 );

wherein the housing ( 8 ) has, on a side of the housing ( 8 ) opposed to the sensor ( 9 ), at least one projection ( 18 , 18 a ) for retaining the chain drive ( 14 ).
