From: Performance analysis and optimization design of variant CR-CR 9-speed automatic transmission
Gear | Transmission ratio |
|---|---|
1 | (K1 + K2 + K1K2)(K4 + 1)(K3 + 1)/K2K3K4 |
2 | (K1 + 1)(K3 + 1)(K4 + 1)/K3K4 |
3 | (K3 + 1)(K4 + 1)/K3K4 |
4 | (K4 + 1)/K4 |
5 | 1 |
6 | (K1 + 1) (K4 + 1)/(1 + K1 + K4+ K1K3+ K1K4) |
7 | (K1 + K2 + K1K2)(K4 + 1)/[K1K3(K2 + 1)+(K1 + K2 + K1K2)(K4 + 1)] |
8 | (K4 + 1)/(1 + K3 + K4) |
9 | (K4 + 1)/(1 + K2K3 + K3 + K4) |
10 | − (K3 + 1)(K4 + 1)/K2K3K4 |
