| 20080314196 | Universal Light Transmission - A light and small-sized gear type multi-stage automatic transmission capable of eliminating the power loss in comparison with a current automatic transmission and usable also for a large-sized vehicle by diversifying gears, wherein backward position, and a neutral position and several gear blocks for changing the shift between HIGH and LOW are combined to operate the transmission with the microcomputer operation. Since the gear for changing the shift between HIGH and LOW can provide the number of speed change by the number of grade of the number of the gears to be combined, the gear for changing the shift between HIGH and LOW can improve the fuel consumption and can cope with an engine brake by utilizing the combination of an electronic parking brake with the selection of the gear. In addition, since the same gear block is used, the manufacturing cost is remarkably reduced. | 12-25-2008 |
| 20090107289 | MULTI-GROUP TRANSMISSION AND METHOD FOR CHANGING GEAR IN A MULTI-GROUP TRANSMISSION - An automated multi-group standard transmission, for a utility vehicle, and a process for changing gears in the multi-group transmission. The multi-group transmission includes at least two multi-speed transmission groups arranged one after the other, such that a multitude of gears can be shifted. A transmission input shaft that can be connected to an engine, via a startup element, is associated with a first transmission group and a second transmission main shaft is associated with a second transmission group. Load shifting mechanisms produce a temporary direct connection between the transmission input shaft and the transmission main shaft such that an intermediate gear can be shifted during a gear change from an original gear into a target gear. The load shifting mechanism enables gear changes that are virtually free of interruptions in load transfer during a gear change from a lower to a higher gear, thus increasing a high operational comfort. | 04-30-2009 |

| 20110259147 | AUTOMATED MULTI-GROUP TRANSMISSION OF A MOTOR VEHICLE AND METHOD FOR OPERATING AN AUTOMATED MULTI-GROUP TRANSMISSION - The invention relates to an automated multi-group transmission of a motor vehicle and a method for its operation, with at least two gearing groups successively disposed in the power flow of the drive train, with a clutch assembly having at least one start-up clutch, by means of which a connection can be established between a drive shaft of a drive motor and a transmission input shaft associated with a first gearing group, with a shifting device, by means of which a connection can be established between the transmission input shaft and a transmission main shaft associated with a second gearing group, whereby the transmission main shaft is designed as a transmission output shaft or is at least functionally connected to a transmission output shaft, and with a means by which the tractive force gear shifting can be carried out. | 10-27-2011 |
| 20130087018 | METHOD FOR ENGAGING AT LEAST ONE SPEED-INCREASING OR SPEED REDUCTION STAGE IN A TRANSFER BOX - A method of shifting at least one of a speed increasing stage (H) and/or a speed reductions stage (L) in a claw shifted transfer gear box (VG) in a drive train of a vehicle having a drive engine and a load shiftable shift transmission (SG). The transfer gearbox (VG) is shifted into the neutral position (N) and, after the synchronization, is shifted into the speed increasing stage (H) or the speed reductions stage (L). During synchronization, the shift transmission (SG) is decelerated or accelerated, by activating at least an additional shift element, so that the output rotational speed (n_SG) of the shift transmission (SG) is matched to the output rotational speed (n_VG) of the transfer gearbox (VG), multiplied by the target gear ratio in the transfer gear box (VG). | 04-11-2013 |
