摘要： 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.

摘要： A group transmission of a motor vehicle having a main transmission and a downstream range group. The range group has two gear steps for different speed ranges and a reversing step for reverse driving. The range group has two planetary gearsets, each with a planet carrier, a sun and ring gears. To engage a driving range for lower speeds, the sun gear of the second gearset and the ring gear of the first gearset are locked to the housing by a first clutch. To engage a driving range for higher speeds, two respective elements of the two gearsets can be connected to one another, in a rotationally fixed manner, by a second clutch. To engage a reversing driving range, the planet carrier of the first gearset and the ring gear of the second gearset are locked relative to the housing by a third clutch.

摘要： A gear unit includes: a stepped planetary gearset, and first and second gear shifting elements. The stepped planetary gearset has first and second sun gears, a first ring gear and a plurality of stepped planet gears rotatably mounted at a first planet carrier. The first ring gear is connected to an output shaft of the gear unit thus being fixed with respect to rotation relative to it. The first planet carrier is connected to a housing and fixed with respect to rotation relative to it. The first gear shifting element drivingly connects the second sun gear to an electric machine in a closed state, and the second gear shifting element drivingly connects the first sun gear to an electric machine in a closed state. One of the two gear shifting elements is in the closed state for driving the output shaft in rotation.

摘要： A power-split transmission (28) with a first power path and a second power path. In this case, the first power path is a mechanical power path and includes a primary planetary gearset (P1), a secondary planetary gearset (P2) and a tertiary planetary gearset (P3). Furthermore, the power-split transmission (28) is equipped with at least four shifting elements. In addition, a method for operating such a power-split transmission (28) is disclosed. Moreover, a drive-train (10) of a working machine with a power-split transmission (28) of the type concerned is presented.

The stepped planetary gearset has at least a first ring gear, a second ring gear and a plurality of stepped planet gears rotatably mounted at a first planet carrier. The first planet carrier drivingly connects to an electric machine. The second ring gear is connected to an output shaft of the gear unit so as to be fixed with respect to rotation relative to it. The first gear shifting element fixes the first ring gear relative to a housing in a closed state, and the second gear shifting element brings the stepped planetary gearset into direct drive in a closed state. One of the two gear shifting elements is in the closed state for driving the output shaft in rotation.

摘要： A multi-speed transmission (9) for a rail vehicle. The multi-speed transmission (9) has at least one transmission input (AN), at least one transmission output (AB), at least one planetary gearset (PR1, PR2), at least one shifting element (SE1, SE2) and a housing (G). The planetary gearset (PR1, PR2) has a sun gear (S1, S2), at least one planetary carrier (PT1, PT2) with planetary gearwheels, and a ring gear (H1, H2), and rotational movement from a drive element (8) is introduced into the multi-speed transmission (9). By actuating the at least one shifting element (SE1, SE2), at least two different transmission ratios can be obtained between the transmission input (AN) and the transmission output (AB).

摘要： Torsional vibration damper arrangement in a housing with a drive-side transmission element, an output-side transmission element, and a planetary gear unit arranged there between having a sun gear, an arm supporting a planet gear, and a ring gear with an energy storage and damping element acting at the planetary gear unit. To increase the damping capacity and to accommodate a large energy storage volume and minimize friction effects due to centrifugal accelerations, one of the planetary gear unit members, the sun gear or the arm or the ring gear, can be coupled to the housing via the energy storage and damping element. The energy storage and damping element has a helical compression spring arranged in a circumferential groove in the transmission housing. The groove is spiral-shaped in axial direction of the transmission housing.
