System Description

- Driveablity during cornering and driving on rough road is improved by mechanically generating oil pressure by connecting 4 units of shock absorbers to front, rear, right, and left by piping lines of 2 systems.
- Oil filling and system diagnosis can be performed using PPMU.

OPERATING PRINCIPLE

During cornering (Front and rear wheels in the outer side of corner: compressing)
When shock absorber in the outer side of corner is compressed during cornering, oil moves along piping path and overflowing oil from piping path flows in accumulator in the outer side of corner. Then, pressure increases by action of gas spring of nitrogen gas according to amount of oil that flows in.
Pressure in the inner side of corner decreases, since oil is discharged from accumulator by stroke (extending direction) of shock absorber.
The pressure difference generates stabilizer-like action to maintain balance in vehicle posture for a steady driving at cornering.






During rough road driving (Front wheel LH: compressing, front wheel RH: extending, rear wheel LH: extending, rear

wheel RH: compressing)
Discharged oil from each shock absorber moves along piping path, but oil does not overflow from piping path, since oil moves in between each shock absorber. Oil does not flow in accumulator and system pressure does not increase.
Since the oil from the contracted shock absorber flows into the shock absorber upper chamber, stabilizer-like action is not generated. This improves the adhesion level and the running performance on rough roads.
