<p>A device for reducing the drop in tractive force during the gear shifting phase of an automatic transmission comprising an automatically actuated drive clutch. The device comprises a rotary storage device that can be coupled, if necessary via two transmission ratio steps (4, 5) that are each assigned a friction clutch (6, 7), to the output shaft of the transmission or, if the transmission has a downstream range group, to the output shaft of the main friction transmission. Only one of the two friction clutches (6, 7) can be activated at any time, and a step up ratio can be achieved and the rotary storage device can be loaded with one of the transmission ratio steps (5). A step down ratio can be achieved and energy can be released from the rotary storage device to the output shaft using the other transmission ratio step (4).</p> |
