Stator torque transmission assembly
View Patent ↗A stator torque transmitting assembly for a vehicle including a stator shaft connected to a stator in a torque converter for the vehicle and arranged to transmit torque from the stator during a torque conversion mode for the torque converter. In some aspects, the assembly includes a first planetary gear set with a first sun gear, a first planetary carrier, and a first ring gear. The first sun gear is rotationally connected to the stator shaft and the first carrier is grounded. A first transmission input shaft is rotationally connected to the first ring gear and to a second carrier in a second planetary gear set in a transmission in the vehicle. A second transmission input shaft, rotationally connected to a turbine in the torque converter, is rotationally connected to a second ring gear in the second planetary gear set.
1. A stator torque transmitting assembly for a vehicle, comprising:
a torque converter comprising a turbine and a stator;
said stator comprising a one-way clutch;
a stator shaft rotationally connected to said one-way clutch and arranged to transmit torque from said stator during a torque conversion mode for said torque converter;
a first planetary gear set comprising a first sun gear, a first planetary carrier, and a first ring gear; and,
a transmission comprising a transmission input shaft and a second planetary gear set, said second planetary gear set comprising a second sun gear, a second planetary carrier and a second ring gear, wherein said stator shaft is rotationally connected to only said first sun gear, said first planetary carrier is grounded, said first ring gear is rotationally connected to said second planetary carrier, said second ring gear is rotationally connected to said transmission input shaft, said transmission input shaft is rotationally connected to said turbine and said turbine is arranged to rotate and wherein said second planetary carrier and said first ring gear are integrally formed.
2. The stator torque transmitting assembly of claim 1 wherein said stator shaft is arranged to transmit torque from said stator to said first planetary gear set during said torque conversion mode for said torque converter.
3. The stator torque transmitting assembly of claim 1 wherein said torque converter further comprises an output hub connected to said turbine, said transmission input shaft is rotationally connected to said output hub, and said second sun gear is grounded.
