DEVICE HAVING SLIDING WEDGE TRANSMISSIONS CONNECTED ONE BEHIND THE OTHER

摘要

The invention relates to a device for braking, clamping, or gripping, comprising a drive that produces a reciprocating motion, wherein the drive comprises a drive device and two sliding wedge transmissions arranged in a housing and wherein the first sliding wedge transmission has a displacement transmission that is smaller than the displacement transmission of the second sliding wedge transmission. The first sliding wedge transmission comprises a following wedge and an angled pressure piece. The second sliding wedge transmission comprises a driving wedge that can be moved between a support element and the following wedge in the wedging direction. During the relative motion of the following wedge and the angled pressure piece, the stroke of the following wedge is limited by a stop arranged on the driving wedge. By means of the present invention, a device is developed that has a simple and space-saving construction and that is also low-maintenance over the long term while having a small drive stroke and large clamping forces.
