<p>A double-clutch transmission includes, but is not limited to two input shafts and three layshafts that are parallel to each other. One or more of the layshafts comprises a pinion that meshes with an output gearwheel on an output shaft. Gearwheels are arranged on the shafts and the shafts comprise seven gearwheel groups for providing seven sequentially increasing forward gear speeds. Each of the gearwheel groups comprises a fixed gearwheel on one of the input shafts, meshing with an idler gearwheel on one of the layshafts. One or more coupling devices of the double-clutch transmission is mounted on one of the layshafts to selectively engage one of the idler gears for outputting these seven gear speeds. Especially, the pinion comprises a first pinion mounted on a first layshaft via a bearing.</p> |
