Multi-speed power transmission |
摘要 |
A simple planetary gearset and four transfer gear pairs are combined to provide five forward speed ratios and two reverse speed ratios in a power transmission. Three selectively engageable clutches controlling three of the transfer gear pairs are engaged in combination with two selectively engageable friction devices controlling the simple planetary gearset to establish four of the forward speed ratios and the two reverse ratios. A fourth selectively engageable clutch, controlling the fourth transfer gear pair establishes a forward ratio numerically central of the aforementioned four forward ratios.
