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.

Most events entered were sprints, but he also raced at circuits. The maximum efficiency of an impulse wheel is achieved when the velocity of the runners at the center line of the nozzle is half the velocity of the incoming water.

Measure the height from the axle centre-line to the underside of the wing opening at both the front and rear of the car and compare with the specified trim heights given in Technical Data at the end of this section. These are naturally stiff.

This involved fitting a new front subframe design,with a larger diameter horizontal hyxrolastic in the subframe. The unit consists basically of a vacuum pump, a pressure pump and a fluid reservoir.

Invented by Sytem automotive engineer Alex MoultonHydragas is an evolution of the previous Hydrolastic system. Cars using the Hydragas suspension system: You are commenting using your Facebook account.

See the example micro generators at the foot of this page – all of which are too large for this application. This ground-breaking design, with its front wheel drive, transverse engine, sump gearbox, inch wheels, and phenomenal space efficiency, was still being manufactured in and has been the inspiration for almost all small front-wheel drive cars produced since the early s. Coloring is added to help show up leaks or hydrolzstic fluid easily.


The system pressures can be adjusted slightly from the specified figures to obtain the specified trim heights, but large variations will indicate wear or damage to the suspension components or body shell. They suspensiion connected from front to back but not from side to side or all around, as in the case of the DS.


Fill in your details below or click an icon to log in: In Citroen presented their DS which had a suspension system markedly different from the ones with which drivers were familiar.

The revised Rover Metro had its suspension interconnected and went on to receive plaudits for the quality of its ride. The ultimate prize is the Blue Bird World Cup.

Garages equipped with hydragas pumping facilities are becoming more and more scarce, and prices can vary dramatically. By the time the chassis had been completed hard labour – it was all done by hand, no power toolsIssigonis had moved to Suspenskon Motors Limited, but Austin supplied a “works” specification supercharged side-valve engine.

They worked together on rubber and hydrolastic suspension – to give the UK some huge motoring successes. These replace the conventional steel springs of a regular suspension design. The Mini being the most popular car ever produced in the UK, with over 5, million cars sold worldwide. You’ll need a vacuum pump to complete the system. In most cases, instructions for operating the unit are systek with it and are normally printed on the top of the unit.

The combination of conical rubber springs and small wheels was one of the many innovative developments that allowed Issigonis to achieve the Mini’s small overall size. Cars using the Hydrolastic suspension system: But they are very similar and of course the Metro was derived from the Mini design, an evolution rather than the Mini revolution.


These are, in essence, miniaturised versions of the displacers used on Hydrolastic-equipped cars being a rubber cone spring with an internal fluid chamber to provide damping. The system pressure is checked using the Suspension Service Unit mentioned above.

At the same time, fluid is forced through the pipe to the rear unit. A long time ago the Midlands of Britain were at the cutting edge of suspension design. These cars used rubber cone and compressed gas suspension units with cross-axle liquid exchange known as Hydrolastic, or Hydragas suspension.

Small bumps were absorbed by the spring for each wheel, suspensionn larger heaves actually moved the piston by overcoming friction and activated the other spring. The Moulton Bicycle is now a design classic, which has continued to be developed over many years, spawning a massive following of devotees and a wide range of models and variants.

In roll, there is no transference of fluid from the displacers, and hence its internal pressure rises. Same effective front-rear interconnection as Hydrolastic, but nothing much to go wrong.

The rot set in at BMC in so many ways. We are great fans of the VW principle, that every man should be able to afford a car.
