Aston Martin Atom
The Aston Martin Atom is a prototype automobile built by Aston Martin (AM). Construction of the car began in 1939 and was completed in 1940. The Atom is one of the first fully functional concept cars ever built. Aston Martin explored several new technologies with the Atom, and its chassis design was the basis for the platform used by AM's post-war models well into the late 1950s. History Construction of the Atom was commissioned by R. Gordon Sutherland, AM's Managing Director and son of Arthur Sutherland, the company's owner. Chief engineer Claude Hill led the design effort. The goal was to produce a small enclosed saloon that was comfortable and possessed good road manners. To meet that goal, emphasis was put on light weight and a rigid chassis. The car's name was chosen to be evocative of something small but powerful. The Atom broke with traditional body-on-frame construction methods. Its chassis used square and rectangular cross-section steel tubing for both the main chass ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Buick Y-Job
The Buick Y-Job, produced by Buick in 1938, was the auto industry's first concept car (a model intended to show new technology or designs but not be mass-produced for sale to consumers). Designed by Harley J. Earl, the car had power-operated hidden headlamps, a "gunsight" hood ornament, electric windows,''Concept Cars'' by Larry Edsall pp19 Edizione White Star wraparound bumpers, flush door handles, and prefigured styling cues used by Buick until the 1950s and the vertical waterfall grille design still used by Buick today. It used a Buick Super chassis, indicated by the word "Super" located above the rear license plate. The car was driven for a number of years by Harley Earl, until he replaced it with a 1951 model car. Sometime after that, the car was restored at the Henry Ford Museum The Henry Ford (also known as the Henry Ford Museum of American Innovation and Greenfield Village, and as the Edison Institute) is a history museum complex in the Detroit suburb of Dearborn, Mi ...

Overhead Camshaft Engine
An overhead camshaft (OHC) engine is a piston engine where the camshaft is located in the cylinder head above the combustion chamber. This contrasts with earlier overhead valve engines (OHV), where the camshaft is located below the combustion chamber in the engine block. ''Single overhead camshaft'' (SOHC) engines have one camshaft per bank of cylinders. ''Dual overhead camshaft'' (DOHC, also known as "twin-cam".) engines have two camshafts per bank. The first production car to use a DOHC engine was built in 1910. Use of DOHC engines slowly increased from the 1940s, leading to many automobiles by the early 2000s using DOHC engines. Design In an OHC engine, the camshaft is located at the top of the engine, above the combustion chamber. This contrasts the earlier overhead valve engine (OHV) and flathead engine configurations, where the camshaft is located down in the engine block. The valves in both OHC and OHV engines are located above the combustion chamber; however an OHV en ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cotal Electrically-activated Epicyclic Gearbox (Autocar Handbook, 13th Ed, 1935)
A preselector gearbox is a type of manual transmission mostly used on passenger cars and racing cars in the 1930s, in buses from 1940-1960 and in armoured vehicles from the 1930s to the 1970s. The defining characteristic of a preselector gearbox is that the gear shift lever allowed the driver to "pre-select" the next gear, usually with the transmission remaining in the current gear until the driver pressed the "gear change pedal" at the desired time. The design removed the need for the driver to master the timing of using a clutch pedal and shift lever in order to achieve a smooth shift in a non-synchromesh manual transmission. Most pre-selector transmissions avoid a driver-controlled clutch entirely. Some use one solely for starting from a standstill. Preselector gearboxes were most common prior to the widespread adoption of the automatic transmission, so they were considered in comparison to the " crash gearbox" type of manual transmission. Preselector gearboxes were often mar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wire Wheels
Wire wheels, wire-spoked wheels, tension-spoked wheels, or "suspension" wheels are wheels whose rims connect to their hubs by wire spokes. Although these wires are generally stiffer than a typical wire rope, they function mechanically the same as tensioned flexible wires, keeping the rim true while supporting applied loads. The term ''suspension wheel'' should not be confused with vehicle suspension. Wire wheels are used on most bicycles and are still used on many motorcycles. They were invented by aeronautical engineer George Cayley in 1808. Although Cayley first proposed wire wheels, he did not apply for a patent. The first patent for wire wheels was issued to Theodore Jones of London, England on October 11, 1826. Eugène Meyer of Paris, France was the first person to receive, in 1869, a patent for wire wheels on bicycles. Bicycle wheels were not strong enough for cars until the development of tangentially spoked wheels. They rapidly became well established in the bicyc ...

Centerlock Wheels
A centerlock wheel is a type of automobile wheel in which the wheel is fastened to the axle using a single, central nut, instead of the more common ring of 4 or 5 lug nuts or bolts. History The centerlock wheel and hub system was first introduced by Rudge-Whitworth in the early 1900s, for use in automobile wire wheels. Initially called "QD" (for "quickly disconnectable") the basic mechanism for "knock-off" style centerlock hubs was patented by 1908. It was quickly adopted by auto manufacturers and racers. Although Rudge-Whitworth knock off hubs were excluded from the 1908 French Grand Prix due to safety concerns, by 1913 the technology was universally used in Grand Prix automobile racing. In 1922, Carlo Borrani licensed the Rudge-Whitworth "knock off" wheel and hub design and started his own company to manufacture them. This company was initially named Rudge-Whitworth Milano, then in the late 1930s was renamed to Carlo Borrani, S.p.A. Borrani wire wheels further popularized t ...

Rudge-Whitworth
Rudge Whitworth Cycles was a British bicycle, bicycle saddle, motorcycle and sports car wheel manufacturer that resulted from the merger of two bicycle manufacturers in 1894, Whitworth Cycle Co. of Birmingham, founded by Charles Henry Pugh and his two sons Charles Vernon and John, and Rudge Cycle Co. of Coventry (which descended from a bicycle company founded by Daniel Rudge of Wolverhampton). Rudge motorcycles were produced from 1911 to 1946. The firm was known for its innovations in engine and transmission design, and its racing successes. Their sales motto was "Rudge it, do not trudge it." The company also produced the first detachable wire wheel in 1907, and was known for its knockoff wheels on sports cars; that brand continued well into the 1960s. Wire wheels In the early 1900s John Pugh, son of company founder Charles Pugh and a pioneer motorist, decided that there had to be a better way of dealing with punctured tyres than having to change the tyre with the wheel ...

Hotchkiss Drive
The Hotchkiss drive is a shaft drive form of power transmission. It was the dominant means for front-engine, rear-wheel drive layout cars in the 20th century. The name comes from the French automobile manufacturer Hotchkiss, although other makers, such as Peerless, used similar systems before Hotchkiss. During the early part of the 20th century chain-drive power transmission was the main direct drive competitor of the Hotchkiss system, with the torque tube also popular until the 1950s. Most shaft-drive systems consist of a drive shaft (also called a "propeller shaft" or Cardan shaft) extending from the transmission in front to the differential in the rear. The differentiating characteristic of the Hotchkiss drive is the fact that the axle housing is firmly attached to the leaf springs to transfer the axle torque through them to the car body. Also, it uses universal joints at ''both'' ends of the driveshaft, which is not enclosed. The use of two universal joints, properly phase ...

Leaf Spring
A leaf spring is a simple form of spring commonly used for the suspension in wheeled vehicles. Originally called a ''laminated'' or ''carriage spring'', and sometimes referred to as a semi-elliptical spring, elliptical spring, or cart spring, it is one of the oldest forms of vehicle suspension. A leaf spring is one or more narrow, arc-shaped, thin plates which are attached to the axle and chassis in a way that allows the leaf spring to flex vertically in response to irregularities in the road surface. Lateral leaf springs are the most commonly used arrangement, running the length of the vehicle and mounted perpendicular to the wheel axle, but numerous examples of transverse leaf springs exist as well. Leaf springs can serve multiple suspension functions: location, springing, and to some extent damping as well, through interleaf friction. However, this friction is not well controlled, resulting in stiction and irregular suspension motions. For this reason, some manufacturers have ...

Spiral Bevel Gear
A spiral bevel gear is a bevel gear with helical teeth. The main application of this is in a vehicle differential, where the direction of drive from the drive shaft must be turned 90 degrees to drive the wheels. The helical design produces less vibration and noise than conventional straight-cut or spur-cut gear with straight teeth. A spiral bevel gear set should always be replaced in pairs i.e. both the left hand and right hand gears should be replaced together since the gears are manufactured and lapped in pairs. Handedness A right hand spiral bevel gear is one in which the outer half of a tooth is inclined in the clockwise direction from the axial plane through the midpoint of the tooth as viewed by an observer looking at the face of the gear. A left hand spiral bevel gear is one in which the outer half of a tooth is inclined in the counterclockwise direction from the axial plane through the midpoint of the tooth as viewed by an observer looking at the face of the gear.

Nyloc Nut
A nyloc nut, also referred to as a nylon-insert lock nut, polymer-insert lock nut, or elastic stop nut, is a kind of locknut with a nylon collar that increases friction on the screw thread. The nylon collar insert is placed at the end of the nut, with an inner diameter (ID) slightly smaller than the major diameter of the screw. The screw thread does not cut into the nylon insert, however, the insert deforms elastically over the threads as tightening pressure is applied. The insert locks the nut against the screw as a result of friction, caused by the radial compressive force resulting from the deformation of the nylon. Nyloc nuts retain their locking ability up to . Trademark There are no registered trademarks filed in the United States for "Nyloc" or "Nylock" that are currently active in regards to fasteners. In Australia, "nyloc" is a registered trademark. Related fasteners A nylon pellet nut is very similar to a nyloc nut except that it uses one or more smaller nylon inserts i ...
