HYDRACTIVE 2 PDF

By admin No comments

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.

Suspension works by means of a rod pushing LHM into the sphere, compressing the nitrogen in the upper part of the sphere.

Advantages of the system Hydropneumatics are inherently superior to steel springs for reasons that are often misunderstood. This was a foretaste of the system that was fitted to the astonishing DS 19 of The hydropneumatic system is a progressive spring-rate suspension, in other words the more it is compressed, the stiffer it becomes.

Is this a Hydractive trait or do all Xantias do this? The BHI of the hydractive 3 suspension calculates the optimum hydractivd height, using the following information:. The top is filled with nitrogen at high pressure, up to 75 barthe bottom connects to the car’s hydraulic fluid circuit.

Starting with Xantia model year and XM model yearall models featured an additional sphere that functioned as a pressure reservoir for rear brakes because of new hydraulic locks, letting the car retain normal ride height for several weeks without running the engine.

Maybe it was jydractive dodgy car?

Citroën hydropneumatic suspension – overview

It sure sounds a more complex system? The result is that the spring rate is kept constant, regardless of the load of the car. Above a schematic of the DS showing the braking system.

The whole high pressure part of the system is manufactured from steel tubing of small diameter, connected to valve control units by Lockheed type pipe unions with special seals made from desmopan rubber, a type of rubber compatible with the LHM fluid. This section needs additional citations for verification. Thanks heaps for the information – Hydracfive certainly will keep my eyes out for hydraactive good condition VSX, the specs though which Mandrake I think do differ from the VSX’s we got here, I dont think the ones here have the hydfactive seats?

The front and rear suspension circuits are identical but hydraulically independent. Hydraulic distribution unit 5. The self-levelling system ensures that there is always the same suspension travel available irrespective of load.

It is the simplest damper and one of the most efficient.

This simplifies the ball valve arrangement with respect to Hydractive I. Timely recharging, approximately every 3 years, is thus vital.

Hydractive 2 Advantages/Disadvantages?

Above – height corrector 3 admits hydraulic fluid which “lengthens” the strut and raises the vehicle to its normal ride height. Where hycractive, and within milliseconds, these computers switch an extra pair of suspension spheres in or out of the circuit, to allow the car a smooth supple ride in normal circumstances, or greater roll resistance for better handling in corners.

Consequently, each time hydarctive suspension would rise, the fluid level in the reservoir dropped, drawing in fresh moisture-laden air.

Ride height correction self levelling is achieved by height corrector valves connected to the anti-roll bar, front and rear. When the suspension operates, the ram pushes oil into the sphere, thereby altering the volume and therefore the pressure of the gas.

Hydractive 2

When the car is too low, the height corrector valve opens to allow more fluid into hyvractive suspension cylinder e. In other words, a fully loaded car will be as equally well controlled as a car with just one passenger. The elements are practically the same hydactive on Hydractive I: So this has had me pondering Add Thread to del.

The only real thing at this stage which is putting me off it at this stage it the “anti sink” valves, not so much what might go wrong with them dont worry, not much does apparently, they dont move much and they are well made due to the fact that they have to regulate so much pressure but the fact that the car doesnt sink to the ground like a “proper” Citroen should.

Sensors provide the necessary input to the computer to determine which mode is appropriate. The time now is If the wrong type of fluid is used, the system must be drained and rinsed with Hydraflush, before draining again and filling with the correct fluid.
