Abstract: A bottom bracket gear mechanism for a bicycle or a pedelec includes a gear mechanism shifting group in which a second element of the first gear set is connected to a first shaft, a third element of the first gear set is connected via a fourth shaft to a second element of the second gear set, and a first element of the first gear set is connected to a fifth shaft. A first element of the second gear set is fixable via a third shaft and the second shifting element. The third shaft is connectable to the fifth shaft via the sixth shifting element. The third element of the second gear set is fixable via a second shaft and via the first shifting element. The second shaft is connectable to the first shaft via the fifth shifting element.

Abstract: A drive train for a vehicle includes an internal combustion engine coaxial to a first axis, a first electric machine, and a second electric machine. The first electric machine has larger dimensions than the second electric machine. The second electric machine is connectable to the internal combustion engine. A rotor axis of the first electric machine is axially offset from a rotor axis of the second electric machine. Additionally, the drive train includes a transmission arrangement connectable to a drive output, with the first electric machine being connectable to the transmission arrangement.

Abstract: A transmission has an input shaft, first and second output shafts, and first and second planetary gear-set, connected together. The first output shaft is rotationally fixed to a first planetary gear-set second element, the second output shaft is rotationally fixed to a second planetary gear-set third element, a first planetary gear-set third element is rotationally fixed to a second planetary gear-set first element via a shaft, and a second planetary gear-set second element is secured to a rotationally fixed component. A first shift element blocks the third planetary gear-set by connecting third planetary gear-set elements in a rotationally fixed manner, a second shift element secures a third planetary gear-set first element to the rotationally fixed component, a third planetary gear-set second element is rotationally fixed to the first planetary gear-set first element via an intermediate shaft, and a third planetary gear-set third element is rotationally fixed to the input shaft.

Abstract: A transmission may include an input shaft, a first output shaft, a second output shaft, a first planetary gearset, and a second planetary gearset connected to the first planetary gearset. The input shaft, the first and second output shafts, and the planetary gearsets may be arranged such that a torque input via the input shaft is converted and distributed in a defined ratio to the two output shafts, and the formation of a combined torque is prevented. At least one element of the first planetary gearset may be connected to at least one element of the second planetary gearset with a shaft for conjoint rotation, and at least one element of the second planetary gearset may be fixed in place on a non-rotating component. A connector may be arranged and configured to passively, and therefore without a control unit and without an actuator, connect the first output shaft and second output shaft.

Abstract: A transmission (2) of a motor vehicle includes a first input shaft (7), a second input shaft (8), an output shaft (9), a first sub-transmission (5) including the first input shaft (7), and a second sub-transmission (6) including the second input shaft (8). The second sub-transmission (6) is a planetary transmission having components including a sun gear (24), a ring gear (22), and a carrier (23). Additionally, the transmission (2) includes an engaging device (S3) associated with the planetary transmission (PG). In a first engagement position (E) of the engaging device (S3), a first component (23) of the components of the planetary transmission (PG) is connected to the second input shaft (8). In a second engagement position (F) of the engaging device (S3), a second component (22) of the components of the planetary transmission (PG) is connected to the second input shaft (8).

Abstract: A transmission (G) for a motor vehicle includes an electric machine (EM1), a first input shaft (GW1), a second input shaft (GW2), an output shaft (GWA), three planetary gear sets (P1, P2, P3), and at least six shift elements (A, B, C, D, E, F). Different gears are implementable by selectively actuating the at least six shift elements (A, B, C, D, E, F), and different operating modes are implementable by selectively actuating the at least six shift elements (A, B, C, D, E, F) in interaction with the electric machine (EM1). A drive train for a motor vehicle with the transmission (G) and a method for operating the transmission (G) are also provided.
