Abstract
A gearbox, in particular for motor vehicles, has an input shaft and an output shaft, as well as a first torque-transmitting device which is arranged between input and output shafts, makes possible various transmission ratios and, in one mode of operation, totally interrupts force transmission from the input shaft to the output shaft. The object of the invention is to provide a cost-effective gearbox with an automatic mode which can transmit high torques and avoid a total load interruption during gear shifts or changes in transmission ratio. This object is attained in the above-mentioned gearbox in that a second torque-transmitting device is arranged parallel to the first device between input and output shafts and transmits, unlike the first device, a selectable torque which is continuously variable from near zero to its maximum possible value.
