Locking Differential
A locking differential is a mechanical component, commonly used in vehicles, designed to overcome the chief limitation of a standard open differential by essentially "locking" both wheels on an axle together as if on a common shaft. This forces both wheels to turn in unison, regardless of the traction (or lack thereof) available to either wheel individually. When the differential is unlocked (open differential), it allows each wheel to rotate at different speeds (such as when negotiating a turn), thus avoiding tire scuffing. An open (or unlocked) differential always provides the same torque (rotational force) to each of the two wheels on that axle. Therefore, although the wheels can rotate at different speeds, they apply the same rotational force, even if one is entirely stationary, and the other spinning. (Equal torque, unequal rotational speed). By contrast, a locked differential forces both left and right wheels on the same axle to rotate at the same speed under nearly all ci ...

Open Differential
A differential is a gear train with three drive shafts that has the property that the rotational speed of one shaft is the average of the speeds of the others, or a fixed multiple of that average. Functional description The following description of a differential applies to a traditional rear-wheel-drive car or truck with an open or limited slip differential combined with a reduction gearset using bevel gears (these are not strictly necessary; see spur-gear differential): Thus, for example, if the car is making a turn to the right, the main ring gear may make 10 full rotations. During that time, the left wheel will make more rotations because it has farther to travel, and the right wheel will make fewer rotations as it has less distance to travel. The sun gears (which drive the axle half-shafts) will rotate at different speeds relative to the ring gear (one faster, one slower) by, say, 2 full turns each (4 full turns relative to each other), resulting in the left wheel maki ...

Off-road
Off-roading is the activity of driving or riding in a vehicle on unpaved surfaces such as sand, gravel, riverbeds, mud, snow, rocks, and other natural terrain. Types of off-roading range in intensity, from leisure drives with unmodified vehicles, to competitions with customised vehicles and professional drivers. Off-roaders have been met with criticism for the environmental damage caused by their vehicles. There have also been extensive debates over the role of government in regulating the sport, including a Supreme Court case brought against the Bureau of Land Management in the United States. Off-road vehicle Travelling over difficult terrain requires vehicles capable of off-road driving such as ATVs. These vehicles have features designed specifically for use in off-road conditions such as extended ground clearance, off-road tires and a strengthened drive-train. Some manufacturers offer vehicles specifically designed for off-road use. Recreational off-roading Some ex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Four-wheel Drive
Four-wheel drive, also called 4×4 ("four by four") or 4WD, refers to a two-axled vehicle drivetrain capable of providing torque to all of its wheels simultaneously. It may be full-time or on-demand, and is typically linked via a transfer case providing an additional output drive shaft and, in many instances, additional gear ranges. A four-wheel drive vehicle with torque supplied to both axles is described as "all-wheel drive" (AWD). However, "four-wheel drive" typically refers to a set of specific components and functions, and intended off-road application, which generally complies with modern use of the terminology. Definitions Four-wheel-drive systems were developed in many different markets and used in many different vehicle platforms. There is no universally accepted set of terminology that describes the various architectures and functions. The terms used by various manufacturers often reflect marketing rather than engineering considerations or significant technical diff ...

Drifting (motorsport)
Drifting is a driving technique where the driver intentionally oversteers, with loss of traction, while maintaining control and driving the car through the entirety of a corner. The technique causes the rear slip angle to exceed the front slip angle to such an extent that often the front wheels are pointing in the opposite direction to the turn (e.g. car is turning left, wheels are pointed right or vice versa, also known as opposite lock or counter-steering). Drifting is traditionally done by clutch kicking (where the clutch is rapidly disengaged and re-engaged with the intention of upsetting the grip of the rear wheels), then intentionally oversteering and countersteering. This sense of ''drift'' is not to be confused with the ''four wheel drift'', a classic cornering technique established in Grand Prix and sports car racing. As a motoring discipline, drifting competitions were first popularized in Japan in the 1970s and further popularized by the 1995 manga series '' Initial ...

Heavy Equipment
Heavy equipment or heavy machinery refers to heavy-duty vehicles specially designed to execute construction tasks, most frequently involving earthwork operations or other large construction tasks. ''Heavy equipment'' usually comprises five equipment systems: the implement, traction, structure, power train, and control/information. Heavy equipment has been used since at least the 1st century BC when the ancient Roman engineer Vitruvius described a crane in ''De architectura'' when it was powered via human or animal labor. Heavy equipment functions through the mechanical advantage of a simple machine, the ratio between input force applied and force exerted is multiplied, making tasks which could take hundreds of people and weeks of labor without heavy equipment far less intensive in nature. Some equipment uses hydraulic drives as a primary source of motion. The term "plant" is used to refer to any mobile type of heavy machinery. History The use of heavy equipment has ...

Tractor
A tractor is an engineering vehicle specifically designed to deliver a high tractive effort (or torque) at slow speeds, for the purposes of hauling a trailer or machinery such as that used in agriculture, mining or construction. Most commonly, the term is used to describe a farm vehicle that provides the power and traction to mechanize agricultural tasks, especially (and originally) tillage, and now many more. Agricultural implements may be towed behind or mounted on the tractor, and the tractor may also provide a source of power if the implement is mechanised. Etymology The word ''tractor'' was taken from Latin, being the agent noun of ''trahere'' "to pull". The first recorded use of the word meaning "an engine or vehicle for pulling wagons or plows" occurred in 1896, from the earlier term " traction motor" (1859). National variations In the UK, Ireland, Australia, India, Spain, Argentina, Slovenia, Serbia, Croatia, the Netherlands, and Germany, the word "tractor" u ...

Forklift
A forklift (also called lift truck, jitney, hi-lo, fork truck, fork hoist, and forklift truck) is a powered industrial truck used to lift and move materials over short distances. The forklift was developed in the early 20th century by various companies, including Clark Material Handling Company, Clark, which made Transmission (mechanics), transmissions, and Yale Materials Handling Corporation, Yale & Towne Manufacturing, which made Hoist (device), hoists. Since World War II, the use and development of the forklift truck have greatly expanded worldwide. Forklifts have become an indispensable piece of equipment in manufacturing and warehousing. In 2013, the top 20 manufacturers worldwide posted sales of $30.4 billion, with 944,405 machines sold. History The middle nineteenth century through the early 20th century saw the developments that led to today's modern forklifts. The forerunners of the modern forklift were manually-powered hoists that were used to lift loads. In 1906, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tow Truck
A tow truck (also called a wrecker, a breakdown truck, recovery vehicle or a breakdown lorry) is a truck used to move disabled, improperly parked, impounded, or otherwise indisposed motor vehicles. This may involve recovering a vehicle damaged in an accident, returning one to a drivable surface in a mishap or inclement weather, or towing or transporting one via flatbed to a repair shop or other location. A tow truck is distinct from a car carrier trailer, which is used to move multiple new or used vehicles simultaneously in routine transport operations. History Ferdinand Porsche of Austro-Daimler developed an artillery tractor for the Austro-Hungarian army in 1908, the M 08. One of the batch was constructed as a recovery vehicle for the others, with a large winch on the rear platform. The wrecker (with lifting jib) was invented in 1916 by Ernest Holmes Sr. of Chattanooga, Tennessee, a garage worker who was inspired after he needed blocks, ropes, and six men to pull a car ou ...

McLaren P1
The McLaren P1 is a limited-production mid-engine plug-in hybrid sports car produced by British automobile manufacturer McLaren Automotive. Debuted at the 2012 Paris Motor Show, sales of the P1 began in the United Kingdom in October 2013 and all 375 units were sold out by November. Production ended in early December 2015. The United States accounted for 34% of the units and Europe for 26%. It is considered by the automotive press to be the successor to the McLaren F1, utilising hybrid power and Formula One technology, but does not have the same three-seat layout. It was later confirmed that the Speedtail served as the actual successor to the McLaren F1. The P1 has a mid-engine, rear wheel drive design that used a carbon fibre monocoque and roof structure safety cage concept called MonoCage, which is a development of the MonoCell first used in the MP4-12C and then in subsequent models. Its main competitors are the LaFerrari and the 918 Spyder. They are all similar in specifica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Land Rover Freelander
The Land Rover Freelander is a compact luxury crossover SUV that was manufactured and marketed by Land Rover from 1997 to 2015. The second generation was sold from 2007 to 2015 in North America and the Middle East as the LR2 and in Europe as the Freelander 2. The Freelander was sold in both two-wheel and four-wheel drive versions. The name 'Freelander' is derived from the combination of 'Freedom' and 'Lander'. After having built exclusively body-on-frame 4WD vehicles for half a century, the first generation Freelander was the brand's first model to use monocoque (unibody) structures, and was offered in three- and five-door body options, including a semi soft-top. The second generation (from 2006) dropped all two-door options, leaving only a five-door stationwagon-like body, and – after 62 years – became the brand's first ever to offer a two-wheel drive option (as of 2010). After a five-year hiatus, the two-door Freelanders were succeeded by the two-door versions of the Ran ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
