| 摘要 |
The invention relates to a power transmission unit, in particular a multiple disk clutch or friction brake, in which a disk carrier that has at least one disk, which has external teeth and is fastened to it in a non-rotating fashion, which disk carrier, in a cylinder section and oriented toward the disk, has axial grooves and axial ribs distributed over the circumference in alternating fashion and is connected to a hub on one side by means of a drive plate spaced axially apart from the disks; a non-rotatable connection between the drive plate and the disk carrier is produced by means of plug-in teeth in order to transmit a torque. The object of the invention is to propose a power transmission unit ( 1 ) in which the axial space is reduced. This object is attained in that additional means are provided for axially fastening the drive plate to the disk carrier; the axial fixing means are embodied so that axial forces that the drive plate exerts on the disk carrier exclusively engage the region of the disk carrier that extends axially from the drive plate in the direction of the disks.
