A motor vehicle includes a transmission and a transmission fluid pump for transport of transmission oil to and within the transmission. The transmission fluid pump has a moving element which is coupled to a summation shaft of a planetary gear train. The planetary gear train has a ring gear which is operated by a first drive, and a sun gear which is operated by a second drive. A freewheel mechanism is arranged between the sun gear or a shaft connected to the sun gear and a further element so that the second drive can be switched off, when the first drive operates at high speeds while yet maintaining proper operation of the transmission fluid pump.

The present disclosure relates to the field of cable processing apparatus and discloses a cable radial cutting system and a reaction force cone processing apparatus with the cable radial cutting system. The cable radial cutting system includes a cutting bracket, a planetary gear set, a first driving piece and a second driving piece which are mounted on the cutting bracket, and a cutting tool driven by the planetary gear set to rotate and move radially, where the first driving piece and the second driving piece jointly drive the planetary gear set to rotate.

An electric powertrain includes a first electric motor that has an uninterrupted connection with a drive shaft of a vehicle. The electric powertrain further includes a first gear train that has an interruptible connection with the drive shaft. In one form, this interruptible connection includes a second carrier and a clutch engagement member.

To provide a compact configuration, the first electric motor and the first gear train are sandwiched between the sun gear and the planet gears.

An electric powertrain includes a first electric motor that has an uninterrupted connection with a drive shaft of a vehicle. The electric powertrain further includes a second electric motor that has an interruptible connection with the drive shaft. In one form, this interruptible connection includes a clutch. The electric powertrain further includes a first gear train in the form of a first planetary gear and a second gear train in the form of a second planetary gear. The clutch in one variation includes a positive clutch in the form of a dog clutch. The dog clutch has a clutch suspension configured to deflect a clutch collar when gearing is misaligned during shifting.

A vehicle includes an engine, a continuously variable transmission including an input shaft coupled to the engine, an output shaft, an electric machine, and a gearing arrangement. The electric machine is configured to actuate the gearing arrangement to change a speed ratio between the input and output shafts. A controller is programmed to, responsive to a request to manually shift the transmission to one of a predetermined number of virtual discrete speed ratios and the engine being OFF, command starting of the engine regardless of a driver-demand torque and operate the electric machine to shift the transmission to the one of the speed ratios.

A drive device has a superimposed transmission, an input shaft connected a main drive machine, one or more auxiliary drives, a hydrodynamic retarder for braking the auxiliary drive, and an output shaft to be connected to a working machine. The superimposed transmission has a planetary transmission, with the input shaft connected to a ring gear and the output shaft connected to a sun gear. The retarder is incorporated into a lubricating oil system of the drive device in parallel. A feed line branches from the lubricating oil system and leads to the retarder. A return line leads from the retarder and opens into the lubricating oil system. A valve enables the feed line to be released in the event of a rapid disconnection or energy supply failure of one of the drives, and thus the retarder can be filled with oil.

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), at least two planetary gear sets (P1, P2), and at least four shift elements (A, B, C, D). Different gears are selectable by selectively actuating the at least four shift elements (A, B, C, D). In interaction with the electric machine (EM1), different operating modes are implementable. A drive train for a motor vehicle that includes such a transmission (G) and to a method for operating same are also provided.

The invention relates to a transmission (1) with a transmission input and a transmission output, with a main gearwheel, which is interposed between the transmission input and the transmission output and which is rotatably mounted about a rotation axis (20) and to which a gearwheel bearing (17) is assigned that can be moved perpendicularly to the rotation axis (20), with a gearwheel drive (21), which serves for rotating the main gearwheel about the rotation axis and with which the main gearwheel (19) is in engagement in an engagement zone (26), and with a gearwheel bearing drive (14), which serves for moving the gearwheel bearing (17) (17). When a torque is input at the transmission input, the gearwheel drive (21) rotates the main gearwheel (19) about the rotation axis. The gearwheel bearing drive (14) causes a movement of the engagement zone (26), wherein the movement of the engagement zone (26) and a circumferential movement of the main gearwheel (19) in the engagement zone (26) are oriented in opposite directions.
