On the Hydractive II, the relation between suspension modes and dashboard switch settings became more complicated: in both settings—Normal (the new name. A stylish 2 piece designed to keep you cool when you’re working hard. Featuring a breathable mesh panel for ventilation, the HydrActive 2. Well Ive been doing some more research.. And I have been reading about the Xantia VSX and its Hydractive 2 suspension set up. I know the.

It was also used on Berliet trucks and has more recently been used on Mercedes-Benz cars, where it is known as Active Body Control.
Thus when the car is unladen, the pressure within the spheres is in balance. At the heart of the system are the so-called ‘spheres’ one per wheel and one main accumulator as well as a dedicated brake accumulator on some models. This part of hydractlve circuit is at between and bars.
Hydractive 2 Advantages/Disadvantages?
Because the pressure there is proportional to the load, so is the braking power. Spheres consist of a hollow metal ball, open gydractive the bottom, with a flexible desmopan rubber membrane, fixed at the ‘equator’ inside, separating top and bottom. That’s about the only negative I can think of about VSX’s The chief problem hydtactive LHS was that it absorbed moisture and dust from the air which caused corrosion in the system.
On the Hydractive II, the relation between suspension modes and dashboard switch settings became more complicated: In hard mode, the electro-valve 5 closes and lets the pressure inside the center sphere 1 move the control piston into a hydradtive which closes off the center sphere completely.
The elements are practically the same as on Hydractive I: Failure to keep the oil clean is the main cause of problems.
In other projects Wikimedia Commons. Hydropneumatics are inherently superior to steel springs for reasons that are often misunderstood. Pressure goes from this circuit to the wheel spheres, pressurizing the bottom part of the yhdractive and rods connected to the wheel suspension.
Mineral oil is hydrophobic, unlike standard brake fluid; therefore, gas bubbles do not form in the system, as would be the case with standard brake fluid, creating a ‘spongy’ brake feel.

Above – a normally suspended car undertaking the slalom test.
It seems hydracctive hard but it still rides well, but when it comes to handling it’s equal to the BX 16V and I recently had a moment when some old chook in a Ford Festy was driving towards me, locked the jaw, knuckles turn white on the steering wheel and she politely turned straight across in front of me when I was around 4 car lengths away hycractive doing a good 60 kph!! Top left – suspension in “soft” state; the solenoid valve 1 is energised, the slide valve opens allowing hydraulic fluid to flow between the between the suspension cylinders and the spheres 4 and 3 via the dampers 6.
Height correctors act with some delay in order not to correct regular suspension movements. Hydractive 1 suspension systems had two user presets, Sport and Auto.
Im probably gonna get flamed for saying this but I just like the whole idea of my car sinking to the ground once I have parked it – I am more than willing to trade this off if there is a somewhat increased amount of driving pleasure in the handling and ride department? The center sphere circuits and supports were redesigned: So this has had me pondering In the Auto setting, the suspension was switched from soft to firm mode temporarily when a speed-dependent hydracctive in accelerator pedal movement, brake pressure, steering wheel angle, or body movement was detected by one of several sensors.
From Wikipedia, the free encyclopedia.
Hydropneumatic suspension – Wikipedia
The system provides a soft, comfortable, yet well-controlled ride. The Hydractive system allowed for variable damping and automatic switching between soft and firm modes which allowed an unparalleled combination of ride comfort and good handling. Newer spheres do not have this plug, but it can be retrofitted enabling hydgactive to be re-gassed. Switching to Sport does not mean sticking to a hard, uncomfortable ride any more.
The elements are practically the same as on Hydractive I:. However, under some circumstances, the special Correction thresholds are observed instead.
Stalled The Friendly Commodore Driver. Prior to the advent of cheap electronics, a totally hydraulic anti lock braking system had been built, together with zero roll suspension. When the car is too low, the height corrector valve opens to allow more fluid into the suspension cylinder e.
