Embodiment Construction

[0028] exist Figures 1 to 6 A preferred first embodiment of a wind-up brake device 1 for a planetary gear 16 or a wind-up brake 1 with a planetary gear 16 is shown in . Features which are not considered essential to the invention in the following description are to be understood as optional. The following description therefore also relates to further exemplary embodiments of the wrap-around brake device 1 which have partial combinations of the features to be explained below.

[0029] The wrap-around brake device 1 is preferably designed as a band brake device. The wrap-around brake device 1 acts on a planetary transmission 16 , which is preferably designed as a power shift transmission. Particularly preferably, it is a 2-gear planetary transmission, which is preferably used in hybrid and pure electric drives of motor vehicles.

[0030] The planetary gear transmission 16 has at least one ring gear 17, the ring gear 17 is provided with an internal tooth structure in its inne...

Abstract

The invention relates to a winding brake device (1) for a planetary gear transmission, having at least one winding element (2) and at least one shift fork (4) displaceable in axial direction, said winding element Having at least one first and second lug means (3a, 3b) and configured to wrap around the ring gear (17) of the planetary gear transmission for brake engagement, the shift fork has at least one first and The second actuating element (5a, 5b) opposite in the axial direction, and the shifting fork is mounted in a housing (8) with at least one first and A second stop (9a, 9b) opposite in the direction in which the switching fork (4) can be moved in the first axial direction The first actuating element is moved in such a way that the first cam arrangement interacts with the first actuating element, while the second stop opposite the first actuating element in the axial direction interacts with the second cam arrangement.

Description

technical field [0001] The invention relates to a winding brake device for a planetary gear transmission, especially for a double-speed planetary gear transmission, and a planetary gear transmission with a winding brake device, especially a double-speed planetary gear transmission. Background technique [0002] WO 02 / 093034 A2 discloses a winding or band brake for braking a brake drum. Band brakes have a floating-mounted spindle with a right-handed thread and a left-handed thread. The brake band wrapped around the brake drum is fixed not only to the right-hand thread but also to the left-hand thread by means of two nuts. Through the rotation of the lead screw by means of the electric motor, the two nuts are moved towards each other, so that the brake band comes into contact with the brake drum and brakes the brake drum, or the brake band and the brake drum interact with each other. away, thereby opening the brake band and releasing the brake drum. [0003] Housing-side st...
