High-powered vehicle drive train
This patent describes a vehicle comprising: an engine having an infinitely variable transmission operatively coupled for transmitting engine power to the transmission's input shaft with the transmission output shaft being operatively connected to the vehicle's drive wheels. The transmission comprising a planetary drive structure includes a drive ring gear carrying a first gear in engagement with a drive gear on the input shaft for rotation of the drive ring gear with the input shaft, a central sun gear and planetary gear members disposed in the annular space between, and in engagement with the drive ring gear and the sun gear and rotatably supported on a planetary carrier. The carrier is supported for rotation with the transmission output shaft and an infinitely variable toroidal traction roller transmission structure including two parallel toridal transmissions having a central input toric disc structure common to both toroidal transmissions and operatively connected to the input shaft. The output toric discs being mounted on a shaft associated with the sun gear of the planetary drive.
