Patent ID: 8197380

Claim:
An automated motor vehicle gearbox comprising: a transmission input shaft (W 1 ), a main gearbox output shaft (W 3 , W 4 ), a transmission output shaft (W 4 ) and a plurality of engagable gears; an engine clutch (K) for engaging and disengaging an input end of the transmission input shaft (W 1 ) with a drive motor (M) for supplying drive to the automated motor vehicle gearbox; the main gearbox output shaft (W 3 ) being hollow and having an input end for receiving drive from the plurality of engagable gears and having an opposed output end connected with a change-under-load friction clutch (K 5 ); the transmission input shaft (W 1 ) being co-axial with the main gearbox output shaft (W 3 ) and passing through the main gearbox output shaft (W 3 ), and an output end of the transmission input shaft (W 1 ) being connected to the change-under-load friction clutch (K 5 ); the transmission input shaft (W 1 ) being coaxial with the transmission output shaft (W 4 ) so that the transmission input shaft (W 1 ) and the transmission output shaft (W 4 ) being rotatable relative to one another; and the change-under-load friction clutch (K 5 ) controllably coupling the transmission input shaft (W 1 ) directly with the transmission output shaft (W 4 ) as desired.
