Power transmission, function - GF27.10-P-2009AHO

TRANSMISSION 724.2 in MODEL 212 

Power transmission, general 

"Power flow" is understood to refer to the transmission paths for A reduction of the output speed in the low gears provides lower driving powers and torques. The engine torque is transferred to the vehicle speeds with high tractive forces and drive torques at the drive drive gears over the mechanical connection between the internal wheels. combustion engine, electrical machine (A79/1), wet clutch, the subsequent automatic transmission and the rear-axle differential. Power transmission in the wet clutch ensues through the nonpositive Depending on the operating condition of the hybrid system, the connection of the internal and external plates, which are pressed vehicle is driven either by the internal combustion engine or the together by the clutch piston.

The pressure in the clutch piston is regulated through the wet clutch major assemblies. control solenoid valve (Y3/8y9). The gears of the individual planetary gear sets are used to forward the torque developed by the wet clutch Further subfunctions are described in separate documents: to the transmission output shaft, depending on the gear ratios and actuated shift elements, with the aid of multidisk clutches and multidisk brakes

A reduction of the output speed in the low gears provides lower vehicle speeds with high tractive forces and drive torques at the drive wheels.

Depending on the operating condition of the hybrid system, the vehicle is driven either by the internal combustion engine or the electrical machine or through the combination of torques on both major assemblies.
