<p>A planetary gear train is arranged to include two planetary gear sets (G1, G2) four clutches (C1, C2, C3, C4) and two brakes (81, B2) and to input rotational energy (engine torque) through a relatively large diameterelement (R1) (in low gears) until a relatively high gear is reached whereafter the input is made through one or both of a smaller diameter element (S1. S2) and the previously mentioned larger one (R1). This arrangement inherently avoids energy wasting closed loop transmission paths from being established between the two gear sets (G1, G2).</p> |
