AUTOMATED MANUAL TRANSMISSION FOR VEHICLE

摘要

PURPOSE: An automatic manual transmission for an automobile is provided to allow a driver to shift gears in a smooth and stable manner by providing additional drive power to the driven wheels of an automobile when gear transmission takes place. CONSTITUTION: A transmission unit (1) includes multiple transmission devices having different gear ratios especially between an input shaft and an output shaft. A closed drive delivering device (5) is installed between a drive supply device (3) that supplies drive to the input shaft of the transmission unit and the output shaft in order to deliver the drive from the drive supply device to the output shaft at a closed gear ratio. The closed drive delivering device includes a drive cone (7), a driven cone (9), and an half toroidal. The drive cone is connected to a spin shaft of the drive supply device. While corresponding to and sharing the same center with the drive cone, the driven cone spins and is connected to the output shaft. The half toroidal includes a roller (11) installed in a way in which the drive is delivered between the drive cone and the driven cone at a closed gear ratio by contacting both cylindrical surfaces of the two cones at the same time and thereby adjusting inclination of the two cones' spin shafts.
