Patent ID: 11333084

Abstract:
An exhaust gas flap includes a flap tube (12), a flap diaphragm (16), in an interior of the flap tube on a pivot shaft (14) rotatable about a pivot axis (A), a pivot drive (30) for the pivot shaft (14) and a coupling device (36) coupling the pivot shaft to a drive shaft (34). The coupling device includes a first coupling area (42) rotationally coupled, positive-lockingly meshed with the drive shaft and a second coupling area (44) rotationally coupled, positive-lockingly meshed with the pivot shaft. A biasing element (58) is supported in relation to the coupling device and in relation to one shaft of the drive shaft and the pivot shaft. The coupling device is axially prestressed, by the prestressing element, away from the one shaft along in the direction of the pivot axis and is prestressed about the pivot axis in relation to the one shaft.
