  • Publication number: 20250137522
    Abstract: An oil guiding component for an oil guiding arrangement has a body rotationally fixedly connectable to a stationary component of the oil guiding arrangement, the stationary component defining a main oil channel. The body defines a first chamber opening in a radial direction toward an outer side of the body and being fluidly connectable to the main oil channel. The body also defines a second chamber opening in the radial direction toward an inner side of the body. The first chamber is outside of the second chamber in the radial direction and overlaps the second chamber in an axial direction. The first chamber is fluidly connected to the second chamber via a connection passage. The second chamber is fluidly connectable to a shaft passage through which an outer side and an inner space of a second output shaft of the oil guiding arrangement are in fluid communication.

  • Patent number: 12253150
    Abstract: A transmission (1) for a drive train of a vehicle (100) includes an input shaft (2), a first output shaft (3), a second output shaft (4) and a differential arranged in power flow between the input shaft (2) and the two output shafts (3, 4). A first output torque is transmittable onto the first output shaft (3) by the first planetary gear set (5). A support torque of the first planetary gear set (5) is convertible in the second planetary gear set (6) such that a second output torque is transmittable onto the second output shaft (4). The second planetary gear set (6) is axially adjacent to the first planetary gear set (5), and the planet gears (5.4) of the first planetary gear set (5) do not axially overlap the planet gears (6.4) of the second planetary gear set (6). A second gear set element in the first planetary gear set (5) is a ring gear (5.2) and is connected to a first gear set element in the second planetary gear set (6), which is a sun gear (6.1), for conjoint rotation. The sun gear (6.

  • Patent number: 12253145
    Abstract: A transmission includes an input shaft, two output shafts, at least three bearings and a differential. A first planetary gear set includes multiple gear set elements, and a second planetary gear set includes multiple gear set elements and is operatively connected to the first planetary gear set. A first output torque is at least indirectly transmittable onto the first output shaft by the first planetary gear set. One of the three bearings is arranged between the second output shaft and a stationary component and delimits the axial position of the second output shaft with respect to the stationary component at least in one axial direction. The second gear set element of the first planetary gear set is axially fixed at least in one axial direction on the first output shaft.

  • Patent number: 12181035
    Abstract: A transmission for a power train of a vehicle, the transmission including an input shaft, a first output shaft, and a second output shaft, where the first output shaft is received at least partially within the second output shaft, and where the first and second output shafts are rotatable. The transmission further includes a differential operatively arranged between the input shaft and the first and second output shafts, where the differential is configured to divide drive power applied at the input shaft onto the first and second output shafts. Moreover, the transmission includes a stationary component. Additionally, the transmission includes a cover between the second output shaft and the stationary component, where the cover defines at least one duct for guiding lubricant, with the at least one duct extending substantially radially.

  • Publication number: 20240360889
    Abstract: A transmission has a differential including a first planetary gear set having a first gear set element connected to an input shaft for conjoint rotation, a second gear set element at least indirectly connected to a first output shaft for conjoint rotation, and a third gear set element that is a ring gear. The differential further includes a second planetary gear set having a first gear set element that is a sun gear, a second gear set element non-rotationally connected to a positionally fixed component, and a third gear set element at least indirectly connected to a second output shaft for conjoint rotation. The differential also includes a connector connecting the ring gear of the first planetary gear set and the sun gear of the second planetary gear set for conjoint rotation, where the connector and the ring gear of the first planetary gear set are integrally bonded.

  • Publication number: 20240308331
    Abstract: A drive train (1) for a motor vehicle (13) includes a prime mover (2) and a transmission (3) with at least one first planetary gear set (P1) that includes gear set elements with a sun gear (P1.1), a planet carrier (P1.2) and a ring gear (P1.3). The prime mover (2) includes an input shaft (5), which at least indirectly transmits drive power onto an input shaft (4) of the transmission (3). The input shaft (4) is connected to one of the gear set elements of the first planetary gear set (P1) for conjoint rotation. The drive shaft (5) is connected via a spline (6) to the input shaft (4) for conjoint rotation. The spline (6) is arranged axially between a toothing (15) of a first gear set element of the first planetary gear set (P1) and an axial stop (8) configured to axially support the input shaft (4) against the drive shaft (5) in one torque direction.
