Patent ID: 8667857

Claim:
A control arrangement for an automated gear shift transmission for a motor vehicle, with a first partial transmission ( 26 ), having a main shaft ( 14 ) and a countershaft ( 16 ) with different gear sets including idler gears and fixed gears, which can be engaged by coupling respectively one idler wheel ( 17 a , 17 b , 17 c , 17 d ) with the countershaft ( 16 ), and a gear actuation system ( 62 ), which has a first fluid-actuated shift device ( 18 ) of the first partial transmission ( 26 ), by means of which at feast one idler wheel ( 17 a ) can be coupled and decoupled to the shaft ( 16 ), wherein the shift device ( 18 ) has a piston ( 63 ) and a cylinder ( 64 ), and the piston ( 63 ) can be moved into a first and a second direction within the cylinder ( 64 ) for coupling and decoupling the idler wheel ( 17 a ), a first gear slide (SS GS 73 ), which is assigned to the first shift device ( 18 ) and by means of which an actuation pressure can be applied to the first shift device ( 18 ) and a supply pressure slide (RS GS), by means of which a supply pressure can be directed to the gear slide (SS GS 73 ) the first gear slide (SS GS 73 ) having a first and a second supply input ( 67 , 68 ) for a first and a second movement direction of a piston ( 63 ) of the shift device ( 18 ) a connection of the supply inputs ( 67 , 68 ) to the shift device ( 18 ) being established and interrupted by means of the first gear slide (SS GS 73 ), the supply pressure slide (RS GS) having a first and a second supply output ( 71 , 72 ), which are respectively connected to the first and the second supply input ( 67 , 68 ) of the gear slide (SS GS 73 ) and the supply pressure slide (RS GS) being designed in such a manner that it can guide a supply pressure optionally to one of the two supply outputs ( 71 , 72 ), the gear actuation system ( 62 ) having a second shift device ( 19 ) of the first partial transmission ( 26 ) and an associated second gear slide (SS GS 51 ) and the second gear slide (SS GS 51 ) having two supply inputs ( 67 , 68 ), which are connected to the supply outputs ( 71 , 72 ) of the supply slide (RS GS) and a blocking device ( 120 , 121 ) for preventing a simultaneous selection of two shift devices ( 18 , 19 ) of the first partial transmission ( 26 ).
