  • Motor vehicle with transmission and transmission fluid pump
    Patent number: 11207965
    Abstract: 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.
