Abstract: A gear transmission includes a first helical-cut gearwheel (1) and a second helical-cut gearwheel (2) engaged for transmitting torques in different directions. The first gearwheel (1) and the second gearwheel (2) each include corresponding ring-shaped thrust collars (4, 5), and corresponding thrust collars (4, 5) each form a race (8, 9, 10, 11) having an overlap region. A first race (8) and a second race (9) form an overlap region for traction torques, and a third race (10) and a fourth race (11) form an overlap region for overrun torques. Each overlap region includes a contact surface or a contact point (14, 15), and each contact point (14, 15) is situated on a contact circle diameter (16, 17). The contact surfaces or contact points (8, 9) for traction torques and the contact surfaces or contact points (10, 11) for overrun torques are radially offset.

Abstract: A toothing arrangement (1) includes at least one first helical-cut spur gear (3) and a second helical-cut spur gear (4), which form a common meshing toothing, and as least one thrust collar (7) with two races (8, 9) for axial load compensation on both sides in the region of the meshing toothing. The annular thrust collar (7) includes an internal gearing (10), which, in the mounted state, is supported in a circumferential groove (11) interrupting the tooth system (5) of the first spur gear (3). At least one rotation prevention means is associated with the thrust collar (7). The rotation prevention means is movable from a radially inner region to a radially outer region of the first spur gear (3) into an interlock position. A transmission may include the toothing arrangement.

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: A transmission for a motor vehicle having a first, a second, a third, a fourth, and a fifth shift element that are selectively actuated to couple a first and a second planetary gear set to each other while selecting different gears between an input shaft and an output shaft. The input shaft is rotationally fixable to a first element of the second planetary gear set via the first shift element and to a second element of the second planetary gear set via the second shift element. The first element of the second planetary gear set is rotationally fixable to a rotationally fixed component via the third shift element, and the second element of the second planetary gear set is rotationally fixable to the rotationally fixed component via the fourth shift element. Additionally, a third element of the second planetary gear set is rotationally fixed to the output shaft.

Abstract: A transmission for a motor vehicle having five shift elements, selective actuation of which couples first and second planetary gear sets together while selecting different gears between an input shaft and an output shaft. The input shaft is rotationally fixable to a first element of the first planetary gear set via the first shift element and to a third element of the second planetary gear set via the second shift element. The first element of the first planetary gear set is rotationally fixable to a rotationally fixed component via the third element, the third element of the second planetary gear set being rotationally fixable to the rotationally fixed component via the fourth shift element. A third element of the first planetary gear set is rotationally fixed to a first element of the second planetary gear set and is rotationally fixable to the rotationally fixed component via the fifth shift element.

Abstract: A powershift-capable multi-stage transmission having multiple forward gear ratios and one reverse gear ratio, a drive shaft (1), an output shaft (2), two planetary gear sets (RS1, RS2) which are coupled or coupleable to one another and which have at least one first, second, and third transmission element (1.1, 2.1; 1.2, 2.2; 1.3, 2.3), and multiple shift elements (10, 20, 30, 40, 50, 60, 70) which are assigned to the planetary gear sets (RS1, RS2) and selective shifting of which gives rise to a transmission ratio between the drive shaft (1) and the output shaft (2). At least three of the shift elements (10, 20, 30, 40, 50, 60, 70) are brakes by which the first, second, or third transmission element (1.1, 2.1; 1.2, 2.2; 1.3, 2.3) of the planetary gear sets (RS1, RS2) can be braked directly or indirectly against a component (G) fixed with respect to a housing.
