Torsion Bar
A torsion bar suspension, also known as a torsion spring suspension, is any vehicle suspension that uses a torsion bar as its main weight-bearing spring. One end of a long metal bar is attached firmly to the vehicle chassis; the opposite end terminates in a lever, the torsion key, mounted perpendicular to the bar, that is attached to a suspension arm, a spindle, or the axle. Vertical motion of the wheel causes the bar to twist around its axis and is resisted by the bar's torsion resistance. The effective spring rate of the bar is determined by its length, cross section, shape, material, and manufacturing process. Usage Torsion bar suspensions are used on combat vehicles and tanks like the T-72, Leopard 1, Leopard 2, M26 Pershing, M18 Hellcat, M46/M47/M48 Patton, M60 and the M1 Abrams (many tanks from World War II used this suspension), and on modern trucks and SUVs from Ford, Chrysler, GM, Mitsubishi, Mazda, Nissan, Isuzu, LuAZ, and Toyota.

Delica
The is a range of vans and pickup trucks designed and built by the Japanese automaker Mitsubishi Motors since 1968. It was originally based on a cabover van and pickup truck introduced the previous year, also called the Delica, its name a contraction of the English language phrase ''Delivery car''. This pickup truck, and a commercial van derived from it has received many names in export markets, being sold as the L300 (later L400) in Europe, Jamaica (discontinued after the third generation) and New Zealand, Express and Starwagon in Australia, and plain Mitsubishi Van and Wagon in the United States. The passenger car versions were known as Delica Star Wagon from 1979 until the 1994 introduction of the Delica Space Gear, which became simply Space Gear in Europe at least. The most recent version (not available as a commercial vehicle) is called the Delica D:5. With the exception of the first, versions of all generations are still being sold in various international markets. In Jap ...

Height Adjustable Suspension
Height adjustable suspension is a feature of certain automobile suspension (vehicle), suspension systems that allow the motorist to vary the ride height or ground clearance. This can be done for various reasons including giving better ground clearance over rough terrain, a lower ground clearance to improve performance and fuel economy at high speed, or for stylistic reasons. Such a feature requires fairly sophisticated engineering. Height adjustment is most often achieved by air suspension, air or oil compression used for the "springs" of the vehicle when the pressure is varied, the vehicle body rises or lowers. Factory systems for cars The first instance of a production vehicle with adjustable (rear only) suspension was on the Citroën Traction Avant, 1954 Citroën 15CVH. This vehicle featured a self-leveling suspension, self-leveling, height adjustable hydropneumatic suspension. Since that time, these systems have appeared continuously on Citroën models, including the Citro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Self-leveling Suspension
Self-levelling refers to an automobile suspension system that maintains a constant ride height of the vehicle above the road, regardless of load. Purpose Many vehicle systems on a conventional vehicle are negatively affected by the change in attitude coming from changes in load - specifically a heavy load in the rear seat or luggage compartment. This change in attitude affects aerodynamic properties, headlight aim, braking, bumpers, shock absorption from the suspension and the vehicle's performance in a collision. Most of the braking power is on the front wheels of a vehicle, which means you will have more effective braking when more weight is over the front wheels. When the rear end has a heavy load, the braking is not as effective. The weight is concentrated on the rear end of the vehicle, and the rear brakes need to do all of the work. When braking quickly in this situation, the front brakes will be easier to lock up because of the lack of weight transfer to the front of the ve ...

Ride Height
Ride height or ground clearance is the amount of space between the base of an automobile tire and the lowest point of the automobile, typically the bottom exterior of the differential housing (even though the lower shock mounting point may be lower); or, more properly, to the shortest distance between a flat, level surface, and the lowest part of a vehicle other than those parts designed to contact the ground (such as tires, tracks, skis, etc.). Ground clearance is measured with standard vehicle equipment, and for cars, is usually given with no cargo or passengers. Function Ground clearance is a critical factor in several important characteristics of a vehicle. For all vehicles, especially cars, variations in clearance represent a trade-off between handling, ride quality, and practicality. A higher ride height and ground clearance means that the wheels have more vertical room to travel and absorb road shocks. Also, the car is more capable of being driven on surfaces that ...

MacPherson Strut
The MacPherson strut is a type of automotive suspension system that uses the top of a telescopic damper as the upper steering pivot. It is widely used in the front suspension of modern vehicles. The name comes from American automotive engineer Earle S. MacPherson, who invented and developed the design. History Earle S. MacPherson was appointed the chief engineer of Chevrolet's Light Car project in 1945. He was tasked with developing a new, smaller car for the immediate post-war market, an effort that led to the Chevrolet Cadet. The Cadet was poised to be a groundbreaking vehicle, and the three prototypes that had been built by 1946 displayed a wide range of innovations. One of these was a revolutionary new independent suspension system that featured what is now known as a MacPherson strut. The Cadet was slated to be the first production vehicle with MacPherson struts, but the project was cancelled in 1947 and never saw commercial production. This was in large part due to GM's ...

Bulkhead (partition)
A bulkhead is an upright wall within the hull (watercraft), hull of a ship, within the fuselage of an airplane, or a car. Other kinds of partition elements within a ship are deck (ship), decks and deckheads. Etymology The word ''bulki'' meant "cargo" in Old Norse. During the 15th century sailors and builders in Europe realized that walls within a vessel would prevent cargo from shifting during passage. In shipbuilding, any vertical panel was called a head. So walls installed abeam (side-to-side) in a vessel's hull were called "bulkheads". Now, the term bulkhead applies to every vertical panel aboard a ship, except for the hull itself. History Bulkheads were known to the ancient Greeks, who employed bulkheads in triremes to support the back of rams. By the Athenian trireme era (500 BC), the hull was strengthened by enclosing the bow behind the ram, forming a bulkhead compartment. Instead of using bulkheads to protect ships against rams, Greeks preferred to reinforce the hull ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vehicle Frame
A vehicle frame, also historically known as its ''chassis'', is the main supporting structure of a motor vehicle to which all other components are attached, comparable to the skeleton of an organism. Until the 1930s, virtually every car had a structural frame separate from its body, known as ''body-on-frame'' construction. Both mass production of completed vehicles by a manufacturer using this method, epitomized by the Ford Model T, and supply of rolling chassis to coachbuilders for both mass production (as by Fisher Body in the United States) and to smaller firms (such as Hooper (coachbuilder), Hooper) for bespoke bodies and interiors was practiced. By the 1960s, unibody construction in passenger cars had become common, and the trend towards building unibody passenger cars continued over the ensuing decades. Nearly all trucks, buses, and most Pickup truck, pickups continue to use a separate frame as their chassis. Functions The main functions of a frame in a motor vehicle ...

Coil Spring
A tension coil spring A coil spring is a mechanical device that typically is used to store energy and subsequently release it, to absorb shock, or to maintain a force between contacting surfaces. It is made of an elastic material formed into the shape of a helix that returns to its natural length when unloaded. Under tension or compression, the material (wire) of a coil spring undergoes torsion. The spring characteristics therefore depend on the shear modulus. A coil spring may also be used as a torsion spring: in this case the spring as a whole is subjected to torsion about its helical axis. The material of the spring is thereby subjected to a bending moment, either reducing or increasing the helical radius. In this mode, it is the Young's modulus of the material that determines the spring characteristics. Spring rate A selection of conical coil springs Spring rate is the measurement of how much load (in pounds) a coil spring can hold until it compresses . The spring r ...
