Diagnostic procedure for gearbox gear connector system

摘要

The invention relates to a diagnosis method for a steering knuckle coupling system of a vehicle gearbox, which comprises at least one complementary mobile steering knuckle and a fixed steering knuckle, A drive actuator for axially moving a mobile grab relative to a fixed grab between a separation position and a meshing position with the fixed grab, and a controller for driving the actuator, which has a memory, Two sensors connected to the controller, the first of which can provide the position of the actuator,And a second position sensor adapted to provide an axial position of the moving crab.The process includes the following steps: detecting the time window to realize the diagnosis, driving the actuator and storing the positions provided by the two position sensors, and generating the diagnostic balance from the stored positions.Abstract figure: 3
