Abstract
A wrap-around braking device for a planetary gear train, having at least one wrap-around element, with first and second cam devices, and is designed to wrap around at least one ring gear of the planetary gear train for braking engagement. A shift fork, which can be moved in the axial direction of the shift fork and which has first and second actuating elements that act oppositely in the axial direction and which is mounted in a rotationally fixed manner in a housing that has at least first and second stops in the axial direction. For braking engagement on the ring gear, which rotates in a first rotational direction, the shift fork can be moved in a first axial direction such that the first actuating element interacts with the first cam device, while the second stop opposite the first actuating element in the axial direction interacts with the second cam device.
