Abstract
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.
