Patent ID: 10247249

Abstract:
A clamping device for a shaft-hub connection in a torque-transferring device in a drive train of a vehicle. The connection is an axial spline connection between an externally toothed shaft and an internally toothed hub. An externally toothed ring is provided for clamping the shaft and hub, wherein the externally toothed ring includes an annular body having external teeth. Fastening tongues of leaf-spring-type design are provided on and extend from the radially inner side of the annular body. Outer ends of the leaf-spring-type fastening tongues are attached to the shaft, and the teeth of the toothed ring mesh with teeth of the hub. By rotating the toothed ring against a force provided by the fastening tongues, a clamping force is produced on the shaft-hub connection in the assembled state and is introduced into the shaft-hub connection through the teeth and fastening tongues.
