  • Actuator arrangement having selector drums for a twin-clutch transmission
    Patent number: 7487691
    Abstract: An actuator arrangement for a twin-clutch transmission has a first and a second partial transmission. The first partial transmission contains odd forward gear stages and the second partial transmission contains even forward gear stages. At least one first and one second selector drum have in each case one controllable drive motor and at least one control cam. Each control cam is assigned at least one cam follower. The control cam of at least one selector drum encircles through at least 360°. The associated drive motor is designed to drive said selector drum through at least 360°. The gear stages are distributed on the two selector drums, and arranged on the control cams, in such a way that at least one direct multiple shift can be carried out.
