Abstract: An electric vehicle drive includes an electric motor, an axle drive and a multistep reduction gear that is arranged between the electric motor and the axle drive, is intended in structural terms for shifting at least two forward gears, and includes precisely three planetary gear stages that are operatively interconnected includes sun gears, internal gears and planet carriers, a transmission input element for attaching the electric motor for conjoint rotation, and a transmission output element for attaching the axle drive for conjoint rotation. The transmission input element being permanently connected to the sun gear of the first planetary gear stage for conjoint rotation. The transmission output element being permanently connected to the planet carrier of the third planetary gear stage for conjoint rotation. At least the planet carrier of the first planetary gear stage and the sun gear of the third planetary gear stage are permanently interconnected for conjoint rotation.

Abstract: A drive train device includes at least one electric motor, at least one axle drive, and a transmission arranged between the electric motor and the axle drive. The transmission has exactly one planetary gear stage, one braking unit, and one clutch unit. The transmission is provided, at least in terms of design, for the selection of two powershiftable transmission gears.

Abstract: A dual clutch transmission device is disclosed. The dual clutch transmission device has a transmission device with a transmission housing, with a coupling housing positioned within the transmission housing and with a lubricant reservoir to receive a lubricant for the transmission device, which includes an oil trap ring connected at least indirectly with the transmission housing, which at least partially surrounds the coupling housing. The oil trap ring has a side facing the coupling housing which is primarily designed as an oil guide surface and which has at least one groove which is intended to guide lubricant into the lubricant reservoir. The dual clutch transmission device also has a gear set with a dry sump to lubricate the gear set.

Abstract: The invention relates to a dual clutch transmission comprising two input shafts (11a, 12a; 11b, 12b) which are provided for respectively linking to a power shift clutch (K1a, K2a; K1b, K2b), a first countershaft (13a; 13b) arranged offset parallel to the input shafts (11a, 12a; 11b, 12b), a second countershaft (14a; 14b) arranged offset parallel to the input shafts (11a, 12a; 11b, 12b), at least five gear wheel planes (Z1a-Z5a; Z1b-Z5b) which each comprise a fixed gear (Z11a-Z51a; Z11b-Z51b) permanently connected in a rotationally fixed manner to one of the input shafts (11a, 12a; 11b, 12b), wherein one of the gear wheel planes (Z4a; Z4b) comprises an idler gear wheel (Z42a; Z42b) arranged coaxially relative to the first countershaft (13a; 13b) and an idler gear wheel (Z43a; Z43b) arranged coaxially relative to the second countershaft (14a; 14b), which form a gear wheel pair for shifting into at least one reverse transmission gear (R1a, R2a), at least nine shift units (S1a-S9a; S1b-S9b) for producing an opera
