  • Publication number: 20260160327
    Abstract: A vehicle differential transmission includes a drive shaft, first and second output shafts each operatively drivingly connected to a wheel, first and second planetary gear sets, an oil catchment device, and an oil feeding device. Each of the first and second planetary gear sets has a sun shaft, a ring gear shaft, and a carrier shaft. Exactly one of the shafts of the first planetary gear set is rotationally fixedly connected to exactly one of the output shafts. Exactly one of the shafts of the second planetary gear set is rotationally fixedly connected to exactly one of the output shafts. The oil catchment device is rotationally fixedly connected to the first carrier shaft. The oil feeding device is arranged on a stationary component and defines at least one channel for feeding lubricant to the oil catchment device via non-rotating components.

  • Patent number: 12631248
    Abstract: A lubricant drip pan for a vehicle transmission housing includes a cup-shaped separating section, which at least partially encloses a receiving area in which a receiving chamber for a rotating gear element in the vehicle transmission is defined when the drip pan is installed in the housing, and separates it from a lubrication collecting area at the bottom of the drip pan, and in which a lubricant reservoir for the vehicle transmission is formed when the drip pan is installed in the housing. There is also a suction section radially outside the separating section, partially lying in the lubricant collecting area. The suction section has a suction port and at least partially delimits a suction chamber, which supplies lubricant from the reservoir when the drip pan is installed, into which the suction port opens.

  • Publication number: 20250155007
    Abstract: A transmission (G) for an electric propulsion system of a motor vehicle includes at least one first planetary gear set (P1), a differential (D) operatively connected to the at least one first planetary gear set (P1), and a first output shaft (AB1) and a second output shaft (AB2) operatively connected to the differential (D). A first element (E11) of the first planetary gear set (P1) is configured to conduct a drive power from an electric machine (EM) into the first planetary gear set (P1). A second element (E21) of the first planetary gear set (P1) is configured to conduct the drive power of the electric machine (EM) out of the first planetary gear set (P1). A third element (E31) of the first planetary gear set (P1) is connected to a rotationally fixed component of the transmission (G) for conjoint rotation.

  • Patent number: 11852224
    Abstract: A gear unit for a motor vehicle electric drive system, has a housing with a middle portion and a first and second axial end portions. The middle portion receives an electric machine. A differential gear is arranged in the second end portion of the housing. The differential gear is connected on the drive side to a first planetary gearset and on the driven side to a first output shaft and second output shaft arranged coaxial to one another. The second output shaft is a hollow shaft, and the first output shaft extends into the second output shaft. A first bearing for rotatable support of the second output shaft is arranged radially between the second output shaft and a structural component of the gear unit, and a second bearing for the rotatable support of the two output shafts is arranged between the first output shaft and second output shaft.
