Abstract: An electro-mechanical actuator for generating an axial actuation force is provided. The electro-mechanical actuator includes an electric machine having a stator (1) and a rotor (2). The electro-mechanical actuator also includes a spindle drive with a rotary element (6) and with an element that is movable in a translatory manner. A rotation of the rotary element (6) may result in a translatory motion of the element that is movable in a translatory manner. The rotor (2) and the rotary element (6) of the spindle drive are coupled to each other in a circumferential direction (U) such that a rotation of the rotor (2) results in a rotation of the rotary element (6) of the spindle drive (5). A rotational play (8) is formed between the rotor (2) and the rotary element (6) of the spindle drive in the circumferential direction (U).

Abstract: A planetary transmission includes a plurality of planetary gear sets. Each of the plurality of planetary gear sets has a plurality of planetary gear set shafts. At least one additional rotatably mounted shaft is connectable to at least one of the plurality of planetary gear set shafts by at least one shift element in order to realize at least one ratio. The at least one additional rotatably mounted shaft is also connectable into power flow between an input shaft and an output shaft by the at least one shift element. The at least one additional rotatably mounted shaft is operatively connected directly to a component fixed to a housing, by which operative connection actuation energy for the at least one shift element is transferable from the component fixed to the housing into the at least one additional rotatably mounted shaft.

Abstract: The invention proposes a dual-clutch transmission with two clutches (K1, K2), the input sides of which are connected with an input shaft (w_an) and the output sides of which are respectively connected with one of two coaxially disposed transmission input shafts (w_K1, w_K2). Further provided are at least two countershafts (w_v1, w_v2) on which idlers (i2, i3, i4, i5, iR) are rotatably mounted. The dual-clutch transmission comprises fixed gears (F1, F2, F3), which are disposed on the two transmission input shafts (w_K1, w_K2) in a rotationally fixed manner and in engagement with the idlers, and output gears (iab1, iab2) respectively provided on the two countershafts (w_v1, w_v2), each of which is coupled to a gearing of an output shaft (w_ab), wherein the output shaft (w_ab) is not coaxially disposed to the input shaft (w_an). A plurality of shift elements (S1, S2, S3) is provided as well, so that at least six power-shiftable forward gears (1, 2, 3, 4, 5, 6) and at least one reverse gear (R1, R2) are shiftable. Only three double-acting shift elements (S1, S2, S3) are provided according to the invention, wherein two idlers (i2, i3, i4, i5, iR) of the countershafts (w_v1, w_v2) are allocated to each double-acting shift element (S1, S2, S3), wherein, in a first operating direction (S1a), one of the shift elements (S1) connects an idler (i3) with the associated countershaft (w_v1) and, in a second operating direction (S1b), connects the two associated idlers (i3, i4) with one another, and wherein two shift elements (S2, S3) respectively connect the associated idlers (i2, i5; i4, iR) with the associated countershafts (w_v1, w_v2) in a rotationally fixed manner.
