Abstract
A double-clutch gearbox includes two primary shafts and at least one secondary shaft. Each of a plurality of gear pairs mechanically couples the primary shaft to the secondary shaft and defines a respective gear. Each gear pair includes a primary gear mounted to the primary shaft and a secondary gear, which is mounted to the secondary shaft and permanently meshes with the primary gear. Synchronizers coaxially mounted to a shaft are coupled to a gear of at least one gear pair and adapted to be actuated to engage the gear with the shaft. Forks that actuate the synchronizers are movably mounted and have corresponding catches. A single control shaft is rotationally mounted about and can be slid axially along a longitudinal axis. A single gear actuator is connected to the control shaft to rotate the control shaft about and axially displace the control shaft along the longitudinal axis.
