Planetary Gearset

Planetary Gearset (Ravigneaux)

Planetary Gearset "Input - Reaction - Output" Chart:

Based on the Ravigneaux design, the A5S 360R planetary gearset is made up of two sections; front & rear. It functions as a single integral assembly with a common planetary carrier and a set of common long planetary gears. It consists of the following components:
- Two separate ring gears,
- Two separate input sun gears (one front, one rear)
- One set of three long planetary gears common to both sections (front-rear).
- One set of three short planetary gears (rear)
- One set of three short planetary gears (front)
- One common planetary carrier.

The gearset has three possible torque inputs:
1. Planetary carrier
2. Front input sun gear
3. Rear input sun gear

Three possible reaction components:
1. Planetary carrier
2. Front ring gear
3. Front input sun gear

and one torque output:
1. Rear ring gear.
