  • AUXILIARY TRANSMISSION FOR A CONTINOUSLY VARIABLE TRANSMISSION WITH ACTIVE SPEED CONTROL
    Publication number: 20090048053
    Abstract: An auxiliary transmission assembly includes a variable ratio gear assembly that is connected between an engine and the primary transmission of a motor vehicle, and an external input device to form a continuously variable transmission for the vehicle. The external input device is operably engaged with the output of the variable ratio gear assembly and can alter the speed of the output independently of the input to the gear assembly from the engine. The amount of variance provided by the external input device is determined by a controller that senses the change in load on the vehicle engine and operates the external input device to maintain the speed of the vehicle in accordance with a user input for the desired speed.
