Operation device for automatic vehicle coupling, has ball screw, which is coupled with coupling unit in manner allowing slip, where ball screw is connected with disengaging device for axial power transmission

摘要

The device has a disengaging device shifting device, which shifts a disengaging device (18) through a ball rotation drive coaxial to an input shaft (10) of a drive chain. One of ball circulating nut and/or ball screw (24) is axially non-relocatable opposite to the input shaft. The ball screw is coupled with a coupling unit in a manner allowing a slip. The ball screw is connected with the disengaging device for axial power transmission.
