Third Gear (3 Range): 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 high clutch, causing the front planetary carrier to rotate counterclockwise.
This driving force is also transmitted to the rear internal carrier through the low clutch making it rotate counterclockwise.
The rear sun gear and rear internal gear rotate at the same speed, and so the rear pinion gear, which rotates with them as a unit instead of on its own axis, transmits the driving force to the driving wheels.
- Though the reduction internal gear rotates clockwise, trying to revolve the reduction pinion gear clockwise, the reduction pinion gear tries to rotate clockwise as the load from the vehicle (force that prevents the reduction carrier from rotating clockwise) is applied to the reduction carrier.
- The force of the reduction pinion gear, which tries to rotate clockwise, tries to rotate the reduction sun gear counterclockwise. However, counterclockwise rotation of the reduction sun gear is locked by the reduction brake. Due to this, driving force of the reduction pinion gear overcomes the load from the vehicle to revolve clockwise while rotating clockwise, and rotates the reduction carrier clockwise.
- Therefore, the reduction gear also rotates clockwise and the driving force is transmitted to the driving wheels.
- During deceleration, engine braking is transmitted in the opposite direction.
