Abstract:
1. A multiple-ratio transmission, comprising: a front-mounted gearset (VS) connected to an input drive shaft ( a rear-mounted gearset (NS) connected to an output drive shaft ( first, second, third, fourth, fifth, and sixth shifting elements (A, B, D, E, A′, D′); wherein by selectable shifting of the first, second, third, fourth, fifth, and sixth shifting elements (A, B, D, E, A′, D′), an input rotation speed (n) of the input drive shaft ( the front-mounted gearset (VS) has at least one of a front-mounted planetary gearset (VS the rear-mounted gearset (NS) has a two-carrier four-shaft transmission having two shiftable rear-mounted planetary gear sets (NS the third free shaft of the rear-mounted gearset (NS) is additionally connected to the fifth shifting element (D′) and rotates, when the fifth shifting element (D′) is engaged, at a rotation speed less than the input drive rotation speed (n) of the input shaft ( the first free shaft of the rear-mounted gearset (NS) is additionally connected to the sixth shifting element (A′) and rotates, when the sixth shifting element (A′) is engaged, at a rotation speed less than the input rotation speed (n) of the input drive shaft (
