  • Transmission for coupling a starter-generator electrical machine to an internal combustion engine
    Patent number: 8052562
    Abstract: A transmission for coupling a starter-generator electrical machine to an internal combustion engine and having a transmission ratio that is a function of the rotational speed of the internal combustion engine. The ratio of the rotational speed of the electrical machine to that of the internal combustion engine can be increased at a lower rotational speed of the internal combustion engine than at a higher rotational speed of the internal combustion engine. A control device is provided for switching the transmission ratio, which is held by means of spring force in a condition in which the ratio of rotational speeds is high, and as the rotational speed of the internal combustion engine rises increases the transmission ratio is switched to a condition in which the ratio of rotational speeds is lower.
