<p>The system has a secure high speed ratio disengaging system (40) including a retractable arm (80) i.e. swivel lever, that pivots between a normal position and a retracted position. The arm allows a disengaging rod (42) to pass from its rest position to an offset position and to occupy its rest position during disengaging of high speed ratio of a gearbox, in the normal and retracted positions, respectively. A single pull off spring (50) brings the disengaging rod to its rest position and brings the retractable arm to its normal position. An independent claim is also included for a vehicle comprising a manually controlled gearbox.</p> |
