An oil duct part to be mounted in a transmission, particularly a motor vehicle transmission, includes a conduit with an inlet port and an outlet port, at least one oil collection region for collecting oil conducted through the conduit, and at least one drain for oil from the at least one oil collection region. The conduit has an oil conducting direction (F) from the inlet port to the outlet port and a conduit wall that is closed all around perpendicularly to the oil conducting direction (F). The at least one oil collection region may have a first reservoir with a first reservoir wall and a first reservoir base, as well as a second reservoir with a second reservoir wall and a second reservoir base.

Oil duct part to be mounted in a transmission, and transmission comprising an oil duct part

The invention relates to a drive unit () for a vehicle, comprising an electric machine () having a rotor shaft () and a transmission () having a transmission shaft (). According to the invention, the rotor shaft () and the transmission shaft () are interlocking and coupled by means of an interlocking toothing (), wherein a lubricant channel () is formed in the transmission shaft (), which feeds into an inner space () of the rotor shaft () at the end facing the rotor shaft () in order to provide lubricant for the interlocking toothing (), wherein the rotor shaft () has an end side () at the axial end facing the transmission shaft (), on which end side one or more openings () are formed, extending from an inner circumference () of the rotor shaft () bordering the inner space () to the outer circumference () thereof, such that the lubricant channel () is fluidically connected to the openings () via the inner space () and the interlocking toothing ().

Drive unit for a vehicle

The invention relates to a multi-speed planetary transmission (). The multi-speed planetary transmission () comprises a driveshaft (), which comprises a sun gear () and a ring gear (), and an output shaft (), which comprises a planet carrier with at least one planet gear (). The drive shaft () and the output shaft () can be connected together or separated from each other by means of a clutch (). The multi-speed planetary transmission () has a freewheel (), via which a shift is carried out between a first transmission ratio i_1 and a second transmission ratio i_2 under a load using the clutch ().

Multi-speed planetary transmission for a vehicle with at least one electric machine

The invention relates to a power-shift multi-speed transmission (), comprising at least one stepped planet gear (), which revolves around a first sun gear () and in a first ring gear (). The first ring gear () is held on a lockable freewheel (). A first planet gear step () of the stepped planet gear () revolves in the first ring gear (), while a second planet gear step () revolves in a second ring gear (), with which at least one brake () is associated.

Power-shift multi-speed transmission

The invention relates to a power-shift multi-speed transmission () provided in the power train of a vehicle, comprising at least one sun gear (), at least one stepped planetary gear (), at least one ring gear (), and an input shaft () and an output shaft (). The power-shift multi-speed transmission () can be shifted into a shift mode of a first speed or into a shift mode of a second speed and vice versa by means of the at least one stepped planetary gear (). A first brake () is associated with a first ring gear () and a second brake () is associated with a second ring gear (). Depending on the actuation of these brakes, in the shift modes there is at least one torque flow under acceleration, or at least one torque flow on overrun, through the power-shift multi-speed transmission ().
