20130160588 | DOUBLE CLUTCH TRANSMISSION HAVING A LAYSHAFT DESIGN - A double clutch transmission of countershaft design having a central shaft and a concentric hollow transmission shaft, one countershaft, and two power-shift elements. Two hollow shafts are disposed on the countershaft coaxially to the countershaft, each of which can be fixed, via one shift device, to the countershaft, and to which at least two gearwheels are fixed. A further hollow shaft is coaxially provided on either the central or hollow transmission shafts and can be connected, via a shift device, to the central or hollow transmission shaft, and to which at least two further gearwheels of the gear stages are fixed. At least three transmission ratios are possible by engaging three of the gear stages on the shift-element side into the power flow, thereby enabling one transmission ratio to be at least partially implemented by a respective sole engagement on the shift-element side into the power flow. | 06-27-2013 |
20130167676 | DUAL CLUTCH TRANSMISSION DESIGNED AS REDUCTION GEARING - A dual clutch transmission designed as a reduction gearing which has concentric central and hollow transmission shafts, exactly one layshaft, and two power shift elements. A hollow shaft is provided coaxially on the layshaft, which can be rotatably fixed to the layshaft, via one shift device, and to which at least two gears of the gear stages are rotatably fixed. A further hollow shaft is provided coaxially on either the central or the hollow transmission shaft, which can be connected, via one of the shift devices, with the central or the hollow transmission shaft and to which at least two further gears of the gear stages are rotatably fixed. At least three transmission ratios are obtainable as a result of engaging the shift element into the power flow in three of the gear stages, by which one transmission ratio results from engaging only one shift element into the power flow. | 07-04-2013 |

20140038762 | TRANSMISSION FOR A VEHICLE - A double clutch transmission for a vehicle comprising partial transmissions with an input shaft positioned on an input axis and an output shaft is positioned on the input axis or is at least positioned parallel to a counter shaft axis. A planetary transmission is connected with the output shaft and at least one of the input shafts can be connected with the output shaft via the planetary transmission. M wheel planes and N shifters are positioned, M and N are each natural numbers which are both greater than or equal to 2, and whereby at least N−1 shifter are positioned on the input shaft axis. At least a shift element of one of the N−1 shifter is connected with a shift element of additional N−1 shifters, and in each case a transmission element of two wheel planes is or can be connected with the shaft. | 02-06-2014 |
20140157924 | MOTOR VEHICLE TRANSMISSION - A motor vehicle transmission having two partial transmissions with coaxial input shafts which can connect to an output shaft. The inputs of the first and second partial transmissions are a central shaft and a hollow shaft, respectively, that are coaxial with the output shaft. A countershaft assembly is parallel to the input and output shafts, to transmit rotation from the drive input to the output via a variety of gears. Gear stages ( | 06-12-2014 |
