TL;DR: In this article, a multiple speed transmission with an input member, an output member, a plurality of planetary gearsets and a multiplicity of interconnecting members and a plurality torque-transmitting mechanisms is presented.
Patent
Multi-stage gearbox
TL;DR: In this article, a multi-stage gearbox consisting of nine forward gears and one reverse gear is described, including four planetary gear sets (P1, P2, P3, P4), eight rotary shafts (1, 2, 3, 4, 5, 6, 8, 9) and six gearshifting elements (03, 05, 14, 16, 18, 49).
Patent
Multi step transmission
TL;DR: In this article, a multi-step transmission of a planetary design is described, which includes a transmission input shaft and a transmission output shaft, and at least six shift elements, including first and second brakes and first, second, third, fourth, fifth, sixth, seventh and eighth shafts.
Patent
Multi-ratio transmission
TL;DR: In this paper, a multi-stage transmission with nine forward gears and one reverse gear comprising four planetary gear sets, eight rotatable shafts and six shift elements is presented, where the sun gear of the first set is connected to the fourth shaft, which is couplable to a housing by the first brake, the carrier of the second set is coupled to the third shaft, and the second brake is detachably connectable to the drive shaft.
Patent
Multistep reduction gear
TL;DR: In this article, a multistep reduction gear consisting of a drive shaft (1) which is connected to a front-mounted group (VS), an output shaft (3) which was connected to the rear-mounted groups (NS), switch elements (A, B, C, D, E) acting on the frontmounted group and switch elements(M, H, L) Acting on the rear mounted group (NS) was introduced.
