| description | A shiftable transmission in which at least two clutches actuated in closing direction by spring force and in opening direction by the exertion of pressure are arranged, wherein output of the transmission is stopped by unpressurized shifting of both actuation devices thereby closing both clutches. When pressure is exerted upon the second actuation device, the actuation force of the first actuation device is composed of a spring force of the first actuation device and a hydraulic force from the pressurization of the second actuation device. The clutch belonging to the first actuation device can thus be impinged upon with different forces depending on whether or not the second actuation device is impinged upon with pressure. |
