On models with Hydrolastic suspension, an auxiliary coil spring is located can be carried out on the suspension or its components, the Hydrolastic system. Hydrolastic is a type of space-efficient automotive suspension system used in many cars produced by British Motor Corporation (BMC) and its. 5 days ago Most components shown below are unique to the Hydrolastic (wet suspension) system and suspension/braking systems on.

Hydrolastic – Wikipedia

There is no point re-inventing the wheel when there is more work to do on the EV drivetrain. The essential element is a sealed container of fluid for each wheel suspension unit. Simply put, another nozzle aimed at the generation wheel in the opposite direction such as to work with return pressure – and give generation on the up-stroke of the car’s suspension, and the re-bound.

In the interim, conventional suspension has made enormous strides meaning the advantages the alternatives offered were comparatively reduced. I dislike post-war town planning.

Hence there are four sealed containers to replace coil springs for example.

sywtem Articles needing additional references from June All articles needing additional references. This in turn transmits the pressure to the gas in the upper diaphragm, which compresses to absorb the shock. Hydrolstic me of new posts via email. The Austin Maxi was the only in production car to feature both systems. He explained that this was: Thus, they are interchangeable. One obvious development that would be necessary for incorporation in a hydragas circuit, is dual flow: The Mini went on to become the best selling British car in history with a production run of 5.

The only “give” in the suspension occurs because of the inherent flexibility of the rubber springs. Small bumps were absorbed by the spring for each wheel, but larger heaves actually moved the piston by overcoming friction and activated the other spring.

So, great concept, crap execution. Starting aroundhe raced a supercharged “Ulster” Austin Seven, later fitting it with a front axle of his own design, leading to employment at Austin.

Why doesn’t the fluid itself compress? The front-to-rear interconnection of the Hydrolastic system means that roll stiffness can differ from pitch stiffness.

These instructions should be read through carefully before attempting to use the unit, and followed accurately throughout the operation.

Later, he was responsible for the Hydrogas system, which was developed for the Austin Allegro car and is still in use on the Rover series and the MGF. This involved fitting a new front subframe design,with a larger diameter horizontal chamber in the subframe. Learn how your comment data is processed. Both systems are designed to be fit-and-forget parts or sealed units. Part of the Automobile series. Hydrolastic suspension has a rubber spring built into it – a sort of mini cone, when compared to the Mini dry cones, while hydragas uses a compressed gas spring.


Alongside the development of suspension systems for cars, Dr Moulton designed his revolutionary Moulton Bicycle. I had an MGF with interconnected Hydrogas.

Such units are generally available for hire, suspenion with suitable suspension fluid, from most tool hire shops.

These are naturally stiff. Leave a Reply Cancel reply Enter your comment here In the market place, such an image is poison. GM invented those MR dampers and fluid some years ago and even Ferrari use them these days; no other damper works better. Both systems attempt to address the ride-handling compromise of car suspension by interconnecting the suspension of the hydrolasticc and rear of the car in some way.


Some of you may have noticed the opportunity that such a system provides in terms of micro energy generation. Hydrolastic can resist body roll while also being smoother-riding. Remember that the ride height of the car will drop as the Hydrolastic system is depressurised, so be careful when working at the rear of the car.

The color blue is a protected feature of the mark. The pressure tank on the unit should be pumped up to the system specified working pressure before opening the connector valve, which will already have been connected to the system pressure valve.

In order to flow to another unit, the fluid has to flow through a valve assembly between the two containers, and then through a long pipe to the other unit.
