CVT-
Continuously Variable Transmission
Analogy between Gears and Levers
Gears and CVTs can be easily understood if we make
an analogy with levers.
In fact, a lever works as a gear, (when small rotations are considered).
The following comparisons between GEARS and LEVERS will
evidence how the IVT works. |
| Two gears in the same
shaft: |
|
| CVT: |
|
| Planetary Gear Set
(PGS) : |
|
| IVT
(=CVT+PGS) : |
|
| IVT: forward: |
|
| IVT: neutral: |
|
| IVT: reverse: |
|
| In the beginning of the 20th century, the first friction
CVTs were simple IVTs.
