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.

It should be noted that, with the Hydrolastic system in the depressurised state, the suspension arms will contact the bump rubbers at both front and rear, but the car can still be driven with complete safety at speeds up to 30 mph 50 kph over metalled roads. S eeed Studio 36V-Micro-hydro-generator. We would agree with him. In roll, there is no transference hydroastic fluid from the displacers, and hence its internal pressure rises.


The Mini went on to become the best selling British car in history with a production run of 5. The design of the displacer units, and the way in which they are mounted means that as the suspension is compressed, the roughly spherical displacer deforms, and hence presents a larger area to the mounting plates. At the same time, fluid xystem forced through the pipe to the rear unit.

In any case, the idea was predated over sydtem decade before by the wonderful Citroen 2CV.

Skip to content A long time ago the Midlands of Britain were at the cutting edge of suspension design. The Metro above turned out to be just the ticket.

The system pressure is checked using the Suspension Service Hydrolasic mentioned above. The means for pressurising the gas in the displacers is done by pre-pressurising a hydraulic fluidand then connecting the displacer to its neighbour on the other axle. Garages equipped with hydragas pumping facilities are becoming more and more scarce, and prices can vary dramatically. Cars using the Hydragas suspension system: They worked together on rubber and hydrolastic suspension – to wystem the UK some huge motoring successes.


History has shown that they have a working life in the region of 15 years and more before leakage and corrosion become issues. More googling will get you a bit supsension info on the Tenneco system. Imagine how good they could be if they were active? With the lower containers being squeezed by the suspension, hysrolastic no way out of the upper containers as in escape to the other end of the car the fluid’s only choice is to compress the spring, giving pretty much the same suspension action as if the spring itself was being compressed directly.

The rules hydrolsstic the Cannonball ZEV International Runs are simple, you must use production vehicle running gear – the car must be road legal. The next question is; what happens if both front and rear units are compressed at the same time, when they’d cancel each other out? The system should be left in this over-pressurised condition for about 30 minutes to allow the vehicle to settle, then the pressure hydrolasyic to its normal specified setting.

Retrieved from ” https: The ultimate prize is the Blue Bird World Cup. At the same time, hydroladtic redesigned geometry helps to prevent dive and lift on braking syspension acceleration, giving an impressively smooth, level ride. They provide an excellent quality of ride without compromising handling, and, providing the damping is set up correctly, don’t “wallow” under cornering, braking and accelerating.

Porsche came up with a superbly simple design in the Beetlethat is unfortunately not suitable as euspension EV donor. After servicing the spares market for some years a buyer was found and the production line was sold. This article needs additional citations for verification. Amongst other things, the rear swing arm metal bearings were replaced with rubber bushes, with oversteer becoming an option over time.

When any part of the Hydrolastic system has been disconnected, or after fitting new displacer units or interconnecting pipes, it is essential that the air is suspenaion from the system and a partial vacuum created before the system is pressurised.


And while they do that, make the fluid magnetorheological for variable damping. Manufacturer MG Part Number: The Turgo is half the size of the Pelton and operates at twice the speed.

Part of the Automobile series. In pitch, as described above, fluid is displaced front to rear, and hence the pressure in the system stays effectively the same, and thus the suspension is much more compliant.

Many hydrolastic systems need an occasional top-up of the hydragas fluid to maintain the correct ride height, which in turn ensures the correct suspension characteristics.

Email required Address never made public. Both are suspension systems rather than just springs, in that they include a damping system to slow the action of the suspension.

While the Metro was praised for its handling, and offered a significant improvement in ride quality over the Miniit was criticised for its tendency to pitch and bounce on uneven roads – precisely the characteristics the interconnection was intended to remove.

The Hydrolastic eystem pressure valves are located at the rear of the car on the sub-frame crossmember. A homemade evacuation and high-pressure system based on a bottle jack hydraulic pump.

Such units are generally available for hire, together with suitable suspension fluid, from most tool hire shops. I used to wonder all those years ago whether a degree of anti-roll could have been achieved by by a cunning cross-connection of the Hydrolastic system fluid pipes side to side front and rear as well as the mere front to rear connection they actually went with. This effect is particularly good on small cars as their shorter wheelbases are more affected by pitching.

The reason nitrogen gas is used, suzpension because it is an “inert” gas – it is stable and does not react with most things, nor hydrolaxtic or temperature.
