<p>The gearbox (72) has couplers (K1, K2, K3) for activation and deactivation of driving areas, and a hydraulic system for controlling variators (67) and the couplers. The hydraulic system is designed such that one of the driving areas is activated in a hydraulic dry-running operation. The driving area has a synchronous gear that is activated during transmission in the dry-running operation, when the actual transmission in the other driving area is larger than the transmission in the synchronous gear.</p> |
