Brake Fluid
Brake fluid is a type of hydraulic fluid used in hydraulic brake and hydraulic clutch applications in automobiles, motorcycles, light trucks, and some bicycles. It is used to transfer force into pressure, and to amplify braking force. It works because liquids are not appreciably compressible. Most brake fluids used today are glycol-ether based, but mineral oil (''Citroën/Rolls-Royce liquide hydraulique minéral'' ( LHM)) and silicone-based (DOT 5) fluids are also available. Standards Most Brake fluids are manufactured to meet standards set by international, national, or local organizations or government agencies. International The International Standards Organisation has published its standard ISO 4925, defining classes 3, 4, and 5, as well as class 5.1, class 6 and class 7 reflecting progressively higher performance for brake fluids. SAE The Society of Automotive Engineers SAE has published standards J1703, J1704, and J1705, reflecting progressively higher performance for b ...

Hydraulic Fluid
A hydraulic fluid or hydraulic liquid is the medium by which power is transferred in hydraulic machinery. Common hydraulic fluids are based on mineral oil or water. Examples of equipment that might use hydraulic fluids are excavators and backhoes, hydraulic brakes, power steering systems, automatic transmissions, garbage trucks, aircraft flight control systems, lifts, and industrial machinery. Hydraulic systems like the ones mentioned above will work most efficiently if the hydraulic fluid used has zero compressibility. Functions and properties The primary function of a hydraulic fluid is to convey power. In use, however, there are other important functions of hydraulic fluid such as protection of the hydraulic machine components. The table below lists the major functions of a hydraulic fluid and the properties of a fluid that affect its ability to perform that function: Composition Base stock The original hydraulics fluid, dating back to the time of ancient Egypt ...

Surfactant
Surfactants are chemical compounds that decrease the surface tension between two liquids, between a gas and a liquid, or interfacial tension between a liquid and a solid. Surfactants may act as detergents, wetting agents, emulsifiers, foaming agents, or dispersants. The word "surfactant" is a blend of ''surface-active agent'', coined . Agents that increase surface tension are "surface active" in the literal sense but are not called surfactants as their effect is opposite to the common meaning. A common example of surface tension increase is salting out: by adding an inorganic salt to an aqueous solution of a weakly polar substance, the substance will precipitate. The substance may itself be a surfactant – this is one of the reasons why many surfactants are ineffective in sea water. Composition and structure Surfactants are usually organic compounds that are amphiphilic, meaning each molecule contains both a hydrophilic "water-seeking" group (the ''head''), and a hydro ...

Triethanolamine
Triethanolamine, or TEA is a viscous organic compound that is both a tertiary amine and a triol. A triol is a molecule with three alcohol groups. Approximately 150,000 tonnes were produced in 1999. It is a colourless compound although samples may appear yellow because of impurities. Production Triethanolamine is produced from the reaction of ethylene oxide with aqueous ammonia, also produced are ethanolamine and diethanolamine. The ratio of the products can be controlled by changing the stoichiometry of the reactants. : Applications Triethanolamine is used primarily in making surfactants, such as for emulsifier. It is a common ingredient in formulations used for both industrial and consumer products. The triethanolamine neutralizes fatty acids, adjusts and pH buffer, buffers the pH, and solubilizes oils and other ingredients that are not completely Solubility, soluble in water. Triethanolammonium salts in some cases are more soluble than salts of alkali metals that might be us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Leyland
British Leyland was an automotive engineering and manufacturing conglomerate formed in the United Kingdom in 1968 as British Leyland Motor Corporation Ltd (BLMC), following the merger of Leyland Motors and British Motor Holdings. It was partly nationalised in 1975, when the UK government created a holding company called British Leyland, later renamed BL in 1978. It incorporated much of the British-owned motor vehicle industry, which in 1968 had a 40 percent share of the UK car market, with its history going back to 1895. Despite containing profitable marques such as Jaguar, Rover and Land Rover, as well as the best-selling Mini, BLMC had a troubled history, leading to its eventual collapse in 1975 and subsequent part-nationalisation. After much restructuring and divestment of subsidiary companies, BL was renamed the Rover Group in 1986, becoming a subsidiary of British Aerospace from 1988 to 1994, then was subsequently bought by BMW. The final surviving incarnation of the c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alex Moulton
Alexander Eric Moulton (9 April 1920 – 9 December 2012) was an English engineer and inventor, specialising in suspension design. Early life and education Moulton's father, John Coney Moulton, was a naturalist working in the Far East. Alex Moulton was the great-grandson of the rubber pioneer Stephen Moulton, the founder of the family business George Spencer Moulton & Co. Ltd, based at Bradford-on-Avon, Wiltshire. Moulton was educated at Marlborough College and the University of Cambridge where he was an undergraduate at King's College, Cambridge. Career During World War II he worked on engine design at the Bristol Aeroplane Company. After the war he joined the family company, which made rubber components such as suspension parts for railway carriages; he turned it towards rubber suspension systems for road vehicles. In the mid 1950s, Moulton developed an experimental rubber suspension which was tested on a Morris Minor. His friend Alec Issigonis heard of this work and ...

Hydrolastic
Hydrolastic is a type of space-efficient automotive suspension system used in many cars produced by British Motor Corporation (BMC) and its successor companies. Invented by British rubber engineer Alex Moulton, and first used on the 1962 BMC project ADO16 under designer Alec Issigonis, later to be launched as the Morris 1100. Description The system replaces the separate springs and dampers of a conventional suspension system with fluid filled displacer units which are interconnected between the front and rear wheels on each side of the vehicle. Each displacer unit contains a rubber spring, and damping is achieved by the displaced fluid passing through rubber valves. The displaced fluid passes to the displacer of the paired wheel, thus providing a dynamic interaction between front and rear wheels. When a front wheel encounters a bump, fluid is transferred to the corresponding rear displacer, then lowers the rear wheel, hence lifting the rear, minimising pitch associated w ...

Anti-lock Braking System
An anti-lock braking system (ABS) is a safety anti-skid braking system used on aircraft and on land vehicles, such as cars, motorcycles, trucks, and buses. ABS operates by preventing the wheels from locking up during braking, thereby maintaining tractive contact with the road surface and allowing the driver to maintain more control over the vehicle. ABS is an automated system that uses the principles of threshold braking and cadence braking, techniques which were once practiced by skillful drivers before ABS was widespread. ABS operates at a much faster rate and more effectively than most drivers could manage. Although ABS generally offers improved vehicle control and decreases stopping distances on dry and some slippery surfaces, on loose gravel or snow-covered surfaces ABS may significantly increase braking distance, while still improving steering control. Since ABS was introduced in production vehicles, such systems have become increasingly sophisticated and effective. Mode ...
