The world's first internal tooth shaving process offers enhanced
planetary ring gear precision, minimising transmission noise.
Not exact matches
Torque is divvied up by a compound
planetary gearset; when slip is detected, an electronically controlled clutch increases or reduces the friction between the two
ring gears to change the front - to - rear distribution.
A clutch locks the
ring gear of the
planetary gearset for a 7.0:1 speed reduction and torque multiplication ratio.
Torque biasing - Depending on the tooth ratio's of the
planetary,
ring and sun
gear, the desired ratio can be designed.
Planetary / epicyclic gearboxes, with the engine driving the Planet
gears, the
ring (outer sleeve?)
The power sources work individually on say the
ring and the
planetary carrier, while the sun
gear is used for power take - off to the wheels.
Because the kick down
ring is not held the kick down
planetary gear set just free wheels.

The
planetary gearset is what's responsible for changing
gear ratios, and it consists of a sun
gear surrounded by smaller planet
gears carried by a planet carrier enclosed in a
ring gear.
While the sun
gear spins, the
planetary gears move around it, either around the
ring gear or locked into it depending on the
gear the transmission is in.
A
planetary gear set has a central
gear, known as the sun
gear, an outer
ring that has internal
gear teeth which is called the
ring gear and two or three other
gears which are called planet
gears and allow the
gear ratio to change as the vehicle accelerates.
The
planetary gears are comprised of the sun
gear, which attaches to the main shaft and the
planetary gears, all of which sits inside a
ring gear.
But it's not a CVT, it's a
ring and
planetary gearset that engages and disengages to create a
gear feel.

As a result, components that would normally contribute to the greatest parasitic loss — driveshaft,
ring / pinion, input clutch plates, servo - hydraulic pump assembly and
planetary gear sets — are all stationary when the vehicle is in front - wheel drive.
