Power flow, 1st gear

Power flow, 1st gear


The input shaft rotates clockwise and is connected to the rear planetary gear train's (P1) ring gear by clutch C1. The result is that the input shaft and the rear planetary gear train's ring gear rotate clockwise as a unit.

Freewheel F2 prevents the front planetary gear train's (P2) ring gear from rotating anticlockwise.

The planet gear runs clockwise on the inside of the front planetary gear train's ring gear at the same time as it rotates anticlockwise.

The planet carrier and the driven intermediate gear rotate clockwise as a unit at a lower speed than the input shaft.

Since the driving intermediate gear rotates clockwise, the driven intermediate gear and the lower planetary gear train's (P3) ring gear rotate anticlockwise as a unit.

The lower planetary gear train's planet gear rotates anticlockwise. Brake B4 and freewheel F3 prevent the lower planetary gear train's sun wheel from rotating.

The lower planetary gear train's planet gear runs anticlockwise round the sun wheel at the same time as it rotates. The lower planet carrier and the final gear rotate anticlockwise as a unit at a lower speed than the driven intermediate gear.
