Fifth Gear: Outline
WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2006 Mazda MPV, 2005 Mazda MPV, 2004 Mazda MPV, 2004 Mazda 6, and 2003 Mazda MPV. However, it is still accessible from the selected car via links, so may be relevant.
- The driving force of the input shaft is transmitted to the front planetary carrier via the high clutch, causing it to rotate counterclockwise.
As a result, the front pinion gear rotates counterclockwise. This rotation causes the front internal gear to rotate at an increased speed and the rear planetary carrier to rotate counterclockwise. The driving force of the rear planetary carrier, whose speed has also been increased, is transmitted to the output gear.
- The driving force of the idler gear is transmitted to the reduction internal gear, causing the reduction pinion gear to rotate clockwise.
- As the direct clutch is engaged, the reduction sun gear and reduction planetary carrier rotate at the same speed, and so the reduction pinion gear, which rotates with them as a unit instead of on its axis, transmitting the driving force to the driving wheels.
- During deceleration, engine braking is transmitted in the opposite direction.
