Automatic gear actuating system for motor vehicle, has gear coupling arrangement with variable power transmission ratios, so that higher actuation force acts on feed shaft during transitions between two switching positions of shaft

摘要

The system has a gear coupling arrangement for coupling a transmission rod (38) and a feed shaft (48). The coupling arrangement has variable power transmission ratios, so that a higher actuation force acts on the shaft during a transition from a switching position of the shaft corresponding to a chosen P-condition, to a switching position of the shaft corresponding to a chosen driving condition.
