Abstract: A tool having a housing assembly, which defines a handle, a motor assembly, a trigger assembly, a spindle and a transmission assembly. The motor assembly is received in the housing assembly and has an output shaft. The trigger assembly is coupled to the housing assembly and is configured for use in actuating the motor assembly. The transmission assembly transmits rotary power between the output shaft of the motor assembly and the spindle. The transmission assembly includes a planetary stage with an input sun gear, an output planet carrier and a compound planet gear having a first planet gear and a second planet gear coupled together for common rotation on the output planet carrier. The planetary stage is selectively operable in a first gear reduction and a second, relatively lower gear reduction in which the compound planet gear cooperates to produce at least one intermediate gear reduction within the planetary stage.

Abstract: Disclosed is a starting device for a transmission. The starting device includes a drive input shaft provided for coupling the starting device to a drive engine connected upstream from the transmission. An output shaft is configured to connect the starting device to a gearset of the transmission. The drive input shaft and the output shaft can be connected rotationally fixed to one another by means of a first shifting element. An electric machine is provided whose rotor is connected to an intermediate shaft. The intermediate shaft is coupled to the output shaft by way of at least one gear step. In order to realize integration of the upstream drive engine and the electric machine, a second shifting element is also provided which, when actuated, forms a rotationally fixed connection between the intermediate shaft and the drive input shaft.

Abstract: A gear-shifting device is disclosed. The device comprises a first motor having a first rotor. The first rotor turns clockwise and counter-clockwise, creating a wobbling action. The device further comprises a compound planetary transmission, comprising a transmission ring attached to a ring gear. The compound planetary transmission receives power from the first rotor. The device further comprises a second motor having a second rotor. The second rotor turns clockwise and counter-clockwise. The device further comprises a shift assembly, comprising a drum, a cap, and a pinion gear. The pinion gear receives power from the second rotor. The drum locks with the pinion gear such that the drum rotates with the pinion gear. The transmission ring is attached to the drum, such that the transmission ring moves laterally as the drum rotates. The ring gear locks and unlocks with the cap as the drum rotates. The wobbling action enables the locking.
