Patent
Seven-speed transmission
TL;DR: A seven-speed transmission includes an input shaft, an output shaft, and a planetary gear arrangement having three planetary gear sets as mentioned in this paper, where the input shaft and output shaft are continuously connected with specific members of the gear sets.
Patent
Multi-speed transmission having stacked planetary gear sets
TL;DR: In this paper, a transmission has an input member, an output member, two stacked planetary gear sets, a third planetary gear set, a plurality of coupling members and torque transmitting devices.
Patent
Dual clutch transmission
TL;DR: In this article, the transmission is operable with at least one reverse speed ratio and a plurality of forward speed ratios between the input member and the output member, provided that the synchronizer assembly and a dual clutch assembly are available.
Patent
Multi-speed transmission having four planetary gear sets for producing at least eight gear speeds
TL;DR: In this paper, a transmission of the present invention has an input member, an output member, four planetary gear sets, a plurality of coupling members and a multiplicity of torque transmitting devices.
Patent
8-speed hybrid transmission
TL;DR: The hybrid transmission has a plurality of members that can be utilized in powertrains to provide eight forward speed ratios and one reverse speed ratio as discussed by the authors, and the hybrid transmission includes a motor/generator, three planetary gear sets, five torque-transmitting devices, one fixed interconnection, three external gear sets and a final drive gear set.
