Dual torque path transmission with switchable radially displacing one-way clutch and fluid coupling brake

A transmission for a vehicle, comprising:

• an input shaft;
• a first dual planetary gearset disconnectable from the input shaft and including a first carrier;
• and,
• a second dual planetary gearset disconnectable from the input shaft and including a second carrier, wherein said first and second dual planetary gearsets are each separately connected to a single output for said transmission, wherein the first dual planetary gearset includes first and second sun gears, wherein the second dual planetary gearset includes third and fourth sun gears, and wherein the first and second carriers are directly connected to the output.

A transmission for a vehicle, comprising:

• first and second separate torque paths connected to a single output for said transmission;
• first and second brakes connected to said first and second torque paths and arranged to switch torque from an input shaft for said transmission between said first and second torque paths;
• and,
• first and second dual planetary gearsets disposed in said first and second torque paths, respectively, wherein:
• the first brake is connectable and disconnectable to two separate components of the first dual planetary gearset;
• the first brake is for grounding the two separate components of the first dual planetary gearset to a casing for the transmission;
• the second brake is connectable and disconnectable to two separate components of the second dual planetary gearset;
• and,
• the second brake is for grounding the two separate components of the second dual planetary gearset to the casing.
