The Audi E-tron GT and Porsche Taycan utilize a two-pace unit on their own rear motor, that has a low to start with equipment and also a significant second gear. Because of this, both equally cars and trucks have phenomenal acceleration yet are certainly Power economical when jogging for sustained durations at substantial speeds.
Drive two provides an intermediate ratio. The forward-push clutch is engaged so the engine drives the 1st ring equipment. The Sunlight gear is braked and also the Earth gears revolve all-around it.
The bands are tightened around the ring gear to circumvent it turning, plus the clutches are utilized to lock the Solar gear and planets.
The gear lever of the rujuk di sini automatic transmission is Ordinarily an electronic switch that guides and sends an instruction on the software that manages the gearbox.
This gearbox aids in The graceful acceleration from small velocities, too it responses well at reduced motor revs.

So, it will require up the drivetrain load when actuated and automatically releases when the following equipment’s clutch assumes the torque transfer. The bands develop into Energetic for manually picked gears, for instance lower assortment or reverse, and operate over the planetary drum’s circumference. Bands are certainly not utilized when the gearbox travel/overdrive selection is selected. Rather, the clutches transmit the torque. However, some scenarios use bands for braking.
The reasoning is that they can line up the equipment they Assume you’re planning to need upcoming on a single clutch while the opposite is still getting used to generate the vehicle, and this enables exceptionally swift gearchanges.
