Title: METHOD FOR CHECKING THE CONFIGURATION SAFETY OF A COUPLING DEVICE
Abstract:
Method for checking the configuration safety of a coupling device (8) for a gear box sliding gear (8c) that is rotationally connected to a drive input shaft (4) of the gearbox and is axially movable on the shaft, on either side of an intermediate neutral position, between two opposite positions of engagement with an idler pinion (6a, 7a), characterised in that a neutral configuration of the coupling device (8) is defined on the basis of a main information (F) relating to the position of the slider gear and its movement setting (C), in which position the transmission of the torque to the wheel is effectively stopped, and in that the start of synchronisation of the slider gear with a pinion (6a, 6b) is only allowed when the device (8) is in this configuration.
