SH-AWD (free-wheel drive control system) of the front and rear axle drive transfer device is directly mounted on the bridge of the front portion, it is assigned to the front axle of the torsion part, the other part is then transmitted to the driveshaft via a carbon fiber unit driving unit. The rear of the drive unit is SH-AWD core component, which includes the three planetary gear sets and the clutch.
1.SH-AWD the noun
SH-AWD (free-wheel drive control system) of the front and rear axle drive transfer device is directly mounted on the bridge of the front portion, it part of torque distribution to the front axle, the other part is transmitted to the rear drive shaft unit through a carbon fiber. The rear of the drive unit is SH-AWD core component, which includes the three planetary gear sets and the clutch.
2.SH-AWD works
First, the torque transmitted from the drive shaft to the acceleration means located at the rear of the drive unit, when the straight running it in a 1: 1 gear ratio of the torque transmitted to the rear axle. However, during cornering, the clutch operation by a hydraulic actuator assembly coupled to the planet carrier and the housing, an output shaft of accelerator can turn faster than the input shaft, the maximum percentage increase 5.
axis accelerometer output means with one hypoid gear set is connected to the rotational drive torque of left and right rear axle 90, the rear SH-AWD driving unit more than the average two electromagnetic clutches directly after the bridge, by controlling the clutches, the former may be changed, the torque distribution. 30 to 70 percentage percentage depending on the circumstances, the rear engine of the total output can be obtained, the left and right sides of the direct electromagnetic clutch may be controlled separately, the limit torque may be assigned all of the wheels of the rear axle to a top.

3.SH-AWD’s
automotive technology development today, it has been difficult to achieve integrated control of the vehicle by simple mechanical structure, necessary to passOver a plurality of sensors to accurately determine the state of the vehicle and the driver’s intention before making a correct response. ECU SH-AWD ECU and the engine ECU and a vehicle stability assist (VSA) brought together, it is obtained from the ECU the engine speed, intake manifold pressure and the gearbox transmission ratio signal, obtained from the VSA ECU’s lateral acceleration, wheel speed and the steering angle data, a comprehensive analysis of these data, SH-AWD is engaged ECU calculate the most reasonable distribution ratio, and the front and rear torque is achieved by controlling the acceleration device and the left and right electromagnetic clutches directly distribution. In cornering acceleration, the ECU can be determined according to the lateral acceleration intention of the driver and the steering angle, and to exert a greater torque in the outside rear wheel, thereby actively assist steering torque providing appropriate. Four-wheel drive system as well as the assembled Evolution 8 S-AWC
having a similar function, which is achieved by the active center differential ACD and super active yaw control system Super AYC good steering performance, while different structures, but they are to help the poor by torque on the steering wheel active form, in order to achieve optimum handling performance.
