VT - Suspension - NEW total control pitch and roll
Optimization of the hydrostatic modulation, for the function of the advanced suspension resulted with anti-roll/pitch bar. Having two angular hydrostatic modulators on one anti-roll bar, capable to transfer reaction on the car body it is possible to compensate roll movement, associated with turning, as it is the case with standard anti-roll bar but, in addition, it is possible to compensate pitch movement associated with acceleration and breaking.
​
As system can be optimized for pressure of the steering assistance one hydrostatic pump can provide energy for the steering assistance and for suspension assistance
​
System can have zero impact mode when it acts as simple anti-roll bar no additional performance no additional CO2. Comfort mode where it is used to simulate soft suspension and sport where it can simulate stiff suspension.
​
It is evolution of the known hydraulic systems but with reduced power consumption, and ready to go capacity without time delay needed to pressurize system / leveling suspension as it was case with known systems, all that due to the potential of the hydrostatic modulation technology...
VT - Suspension- OLD active anti-roll bar
As it can be seen on image below practically the same hydrostatic modulator that is used to modulate the torque in the driveline can be used to modulate torque inside active torsional bar i.e. it is capable to improve overall suspension performance. As most of the elements can be used in creation of the AWD4WD driveline and active suspension bar it is evident that due to the huge part number unit cost will be reduced with benefit regarding cost /performance ratio.
One possibility of the integration is presented below...
As it is evident, at this level of the VT R&D only roll control can be improved. In the line of the spirit of VT approach i.e. going for 'out of box' solutions new concepts that can provide roll and pitch control as well as height control are under investigation so further improvements can be expected in the future.
