Automatically actuated gearbox moves change sleeve back towards switching position if detector detects that it has been displaced away from switching position without driver gear change

摘要

The gearbox has a detector (51) of the displacement distance of a gear change sleeve into a set position that is arranged by control elements (40,50) between a switching position and an idle position and a controller (6) for operating the control elements to move the sleeve back towards the switching position if the detector detects that it has been displaced away from the switching position, without a driver gear change occurring, by a distance less than a defined position in the engagement region An Independent claim is also included for a control method for an automatic gearbox.
