Patent ID: 7895910

Claim:
A gearbox with six or more forward gears for a single-clutch or twin-clutch motor-vehicle transmission, comprising: at least one input shaft, a first output shaft which is parallel to and disposed at a higher level than the at least one input shaft, a second output shaft which is parallel to and disposed at a lower level than the at least one input shaft, a first driven gearwheel and a second driven gearwheel which are idly mounted on opposite ends of the first output shaft, a third driven gearwheel and a fourth driven gearwheel which are idly mounted on opposite ends of the second output shaft, and a first driving gearwheel and a second driving gearwheel which are drivingly connected for rotation with the at least one input shaft on opposite ends thereof, the first driving gearwheel meshing both with the first driven gearwheel and with the third driven gearwheel to implement a fourth gear and a sixth gear, respectively, and the second driving gearwheel meshing with the fourth driven gearwheel to implement a first gear, wherein the gearbox further comprises: an intermediate shaft parallel to the at least one input shaft, an intermediate gearwheel idly mounted on the intermediate shaft and meshing with the second driven gearwheel, and a third driving gearwheel which is drivingly connected for rotation with the at least one input shaft beside the second driving gearwheel on a side facing towards the first driving gearwheel, and which meshes with the intermediate gearwheel on the intermediate shaft to implement a reverse gear.
