POWERTRAIN OUTLINE


BHE051301026T08

• In the powertrain system, hydraulic pressure is transmitted from the control valves to operate the clutches and brakes, and the planetary gear changes the gear ratio according to the vehicle driving condition.

• To improve shift quality, a plate-type clutch pack 2-4 brake, which has optimum control at low oil temperatures and is unaffected by changes over time, is used.

• A highly rigid transmission case has been adopted to reduce noise and vibration.

• The powertrain system of the RC4A-EL type consists of three pairs of clutches, two pairs of brakes, a one-way clutch, and two pairs of single type planetary gears.
