  • Patent number: 11400804
    Abstract: A transmission arrangement for a hybrid drive of a motor vehicle, in particular a utility vehicle. The transmission arrangement has a change-speed transmission (1), in particular a group transmission (1) with a drive output side (1b), a drive output flange (2) and a countershaft (VW). An add-on transmission (3) is arranged on the change-speed transmission (1) and has at least one electric machine (EM) and at least one gear ratio step (Ü1). The at least one electric machine (EM) is connected to the countershaft (VW) by way of the at least one gear ratio step (Ü1) and can be engaged as an additional electric drive.

  • Publication number: 20190077246
    Abstract: A method of operating a vehicle having a hybrid drive, a transmission with shift elements, a drive output with a brake, a main transmission with input shafts, an output shaft and planetary gear sets (PG1, PG2). The main transmission has five gear planes. One shift element can connect a gear plane to an element of gear set (PG1) adjoining the main transmission. Another shift element couples a further element of gear set (PG1) either to the output shaft or a housing. An electric machine is permanently connected to an element of gear set (PG2). If, while driving with a transmission gear engaged, the drive output brake is engaged for a full brake application, a shift element of the transmission is first relieved by the electric machine and/or a brake assigned to one of the input shafts and then subsequently disengaged to decouple the combustion engine from the drive output.

  • Publication number: 20080141805
    Abstract: The invention relates to a shifting device (1) for a group transmission with a first switching device (9) for switching the gear steps of a group, a second switching device (10) for switching the groups of the group transmission, and a locking device (22), which features a locking member (23), which can be moved from a releasing position into a locking position, in which the first switching device (9) is locked in a neutral position. Inventively, the locking member (23) can be moved independently of a switching movement of the second switching device (10) from the releasing position into the locked position. The invention also involves a method for controlling a switching device (1) for a group transmission.

  • Patent number: 7272990
    Abstract: An automatic multiple-gear transmission, in particular a power-bifurcated auxiliary transmission for motor vehicles, is described, in which several power paths are provided in a transmission housing (24) between a transmission input shaft (3) and a transmission output shaft (4) for the shifting of gears. The gears are presented with several conversion devices (8, 9, 10) that can be hooked up via control elements (5, 6, 7) into a power flow. At least one of the conversion devices (8, 9, 10) is located at least partially in a transmission housing (24) in such a way that the radial and tangential forces can be transmitted directly to the housing when the conversion device (8, 9) is hooked up.

  • Patent number: 6799411
    Abstract: An apparatus for inserting individual piece goods (3) into containers (4) has a first conveyor (1) for feeding the individual piece goods (3), and a second conveyor (2) for feeding the containers (4), and at least one picker unit (5). At least one of the at least one picker units (5) inserts a number x of piece goods (3) from the first conveyor (1) into a container (4), the container (4) holding a number N>x of piece goods (3). The apparatus also has at least one separate transfer unit (U) for transferring the final N−x piece goods (3) into the container (4) holding N piece goods (3), at least one of the at least one picker units (5) transferring the N−x piece goods (3) from the first conveyor (1) into the transfer unit (U).
