  • Patent number: 10759265
    Abstract: A transmission having five planetary gearsets and seven shift elements for achieving various ratios between drive and output shafts. A forward gearset has three shafts. Two intermediate gearsets have four shafts. Two main gearsets have at least four shafts. Depending on the shift states of the second and third shift elements, the forward gearset can generate two rotational speeds at the output side, which transfer from a forward gearset shaft to an intermediate gearset shaft. Depending on the shift states of the first to fifth shift elements, the intermediate gearset can generate eight rotational speeds at the output side, which pass from another intermediate gearset shaft to a main gearset shaft. Depending on the shift states of the seven shift elements, the main gearset can generate up to fourteen forward and two reverse gears at the output side, which are transferred by another main gearset shaft to the output shaft.

  • Publication number: 20200132171
    Abstract: A transmission (G) for a motor vehicle. The transmission (G) comprises a transmission input (GW1-A), a transmission output (GW2-A), first, second, third and fourth planetary gearsets (P1, P2, P3, P4) and first, second, third, fourth, fifth and sixth shift elements (B1, B2, K1, K2, K3, K4). Ten forward gears and one reverse gear can be achieved between the transmission input (GW1-A) and the transmission output (GW2-A) by selectively operating the six shift elements (B1, B2, K1, K2, K3, K4). A drive train for a motor vehicle having such a transmission (G) is also disclosed.

Selective actuation of the six shift elements (B1, K1, K2, B2, K3, K4) implements eleven forward gears and two reverse gears between the drive shaft (GW1) and the output shaft (GW2-A). A drive train for a motor vehicle having such a transmission (G) is also disclosed.

  • Publication number: 20200040968
    Abstract: A transmission (G) for a motor vehicle which has a transmission input (GW1-A), a transmission output (GW2-A), five planetary gear sets (P1, P2, P3, P4, P5) and six shifting elements (B1, B2, K1, K2, K3, B3). By selectively actuating the six shifting elements (B1, B2, K1, K2, K3, B3), ten forward gears and one reverse gear can be selected between the transmission input (GW1-A) and the transmission output (GW2-A). Further, the drive train is typically incorporated into a motor vehicle.

  • Publication number: 20190193560
    Abstract: An auxiliary power take-off assembly (32) for a transmission (6) of a motor vehicle (2) having a torque converter (8). A driveshaft (30) is permanently connected to a drive motor (4), via the pump shaft (24) of the torque converter (8). In addition, the auxiliary power take-off assembly (32) has a transmission drive chain which includes at least a drive input element (34) and a drive output element (42) connected to an additional assembly (66) to be driven, and a shifting element (64, 68). The shifting element (64, 68) is functionally arranged between the driveshaft (30) and the drive input element (34) of the transmission chain for the optionally connecting the driveshaft (30) to the drive input element (34).

  • Publication number: 20180339586
    Abstract: A planetary-stage automatic transmission with a transmission housing which has a first region in which a transmission input shaft is positioned, a transmission output shaft and a plurality of planetary-stages for the creation of different gear ratios. A hydrodynamic startup has a turbine wheel and connects an engine to the transmission input shaft of the planetary-stage automatic transmission. A power take-off assembly comprises a drive wheel and is positioned in a second region in the transmission housing, between the hydrodynamic startup and the first region which accommodates the planetary-stages. The turbine wheel is connected with the drive wheel of the power take-off assembly. A rotational speed sensor is positioned in the second region of the transmission housing for detecting the rotational speed of the transmission input shaft.

  • Patent number: 9447848
    Abstract: A transmission which has drive input and output shafts, a housing, two planetary gearsets (PR1, PR2), and at least three shifting elements which produce three gears or ratios. A ring gear of the gearset (PR1) and the input shaft are connected for forming a first shaft, a carrier of gearset (PR1) and the output shaft are connected for forming a second shaft, a ring gear of gearset (PR2) forms a third shaft, sun gears of gearsets (PR1, PR2) are connected for forming a fourth shaft, and carrier of gearset (PR2) couples the housing. The first shifting element is arranged in the force flow between the third shaft and the housing, the third shifting element is arranged in the force flow between the second and third shafts, and the second shifting element is arranged in the force flow either between the first and second shafts or the second and fourth shafts.

  • Patent number: 9435407
    Abstract: A transmission having a drive input shaft (AN), a drive output shaft (AB), a housing (G), at least two planetary gearsets (PR1, PR2), and at least three shifting elements (A, B, C) whose selective engagement produces various transmission ratios between the drive input shaft (AN) and the drive output shaft (AB), so that at least three gears can be obtained. To obtain a gear in each case, two shifting elements are engaged and a further shifting element is disengaged.
