Yamaha Niken
The Yamaha Niken is a 845 cc tilting three-wheeler motorcycle, manufactured since 2018 by Yamaha Motor and sold worldwide. Overview The Niken is a commercial version of the concept bike "MWT-9" announced by Yamaha in 2015. As part of Yamaha's LMW line of bikes - Leaning Multi Wheel - the Yamaha Tricity, Tricity with 125cc had previously appeared in 2014. The basic concept is that the two front wheels move in conjunction with each other when the vehicle body is tilted, while the body can be moved like a normal motorcycle. The name ''Niken'' is a coined word meaning "two swords", referring to the dynamic movement of the front two wheels like a sword master's two blades. The development concept was called "New Type of Agility & Controllability". The model was shown as a concept vehicle at the 2015 Tokyo Motor Show, and launched at the 2017 show. It was announced for release in Japan on September 13, 2018, and order reception began on the same day. Technology Vehicle equipm ...

Quadrilateral
In geometry a quadrilateral is a four-sided polygon, having four edges (sides) and four corners (vertices). The word is derived from the Latin words ''quadri'', a variant of four, and ''latus'', meaning "side". It is also called a tetragon, derived from greek "tetra" meaning "four" and "gon" meaning "corner" or "angle", in analogy to other polygons (e.g. pentagon). Since "gon" means "angle", it is analogously called a quadrangle, or 4-angle. A quadrilateral with vertices A, B, C and D is sometimes denoted as \square ABCD. Quadrilaterals are either simple (not self-intersecting), or complex (self-intersecting, or crossed). Simple quadrilaterals are either convex or concave. The interior angles of a simple (and planar) quadrilateral ''ABCD'' add up to 360 degrees of arc, that is :\angle A+\angle B+\angle C+\angle D=360^. This is a special case of the ''n''-gon interior angle sum formula: ''S'' = (''n'' − 2) × 180°. All non-self-crossing quadrilaterals tile the plane, b ...

Piaggio MP3
The Piaggio MP3 (''Moto Piaggio a 3 ruote'', "Piaggio moto with 3 wheels") is a tilting three-wheeled scooter by Italian manufacturer Piaggio. First marketed in 2006, it is noted for its combination of two front wheels and a single rear wheel. Suspension mechanism Utilising its three-wheel mechanism developed by Piaggio together Marabese Design, the MP3 can be stopped and parked, without using a traditional kickstand or centre stand, and can be parked on irregular or side-sloping ground. The front suspension is similar to the single-sided trailing arm of Vespa-style suspensions, linked by an alloy parallelogram and a central steering arm. When moving at slow speeds or stopped, the rider maintains balance by maintaining forward motion or placing feet on the ground. The front suspension locks or unlocks using a switch, which is located just below the throttle on the right handlebar. The suspension lock can only be activated manually, at low speeds or at a stop; the lock is au ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Honda Gyro
The Honda Gyro is a family of small, three-wheeled motorcycles sold primarily in Japan, and often used for delivery or express service. These vehicles are tilting three-wheelers. They combine a tricycle's stopped & low-speed stability with a leaning main-body for stability while turning at speed. They resemble a scooter with a small hinged rear pod containing the engine and two drive wheels. This particular variation was developed and patented by George Wallis of G. L. Wallis & Son in Surbiton, Surrey in 1966. It was first marketed in the failed BSA Ariel 3 of 1970, then licensed to Honda. Honda has built seven models with this configuration. The first Stream was introduced in 1981, followed closely by three other personal transport versions, the Joy, Just, and Road Fox. All were short-lived, but the cargo-oriented Gyro line begun in 1982 found a ready market, with all three variants still in production in 2015. These vehicles were all powered by a 49 cc two-stroke engine up u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Motorized Trikes
List of motorized trikes is a list of motorized tricycles also called trikes, and sometimes considered cars. There are three typical configurations: motorized bicycle with sidecar; two wheels in the rear, one in the front (aka trike); and two in front, one in the rear (aka reverse trike). However, language and definitions vary. One of the most successful trikes of its day was the De Dion-Bouton tricycle; from 1897 until the start of the 20th century about 15,000 licensed copies were sold, with De Dion Bouton usually supplying the engines, and it was overall the most popular motor vehicle in Europe. Trikes have caused tautological confusion and simply defied typical two and four-wheel classifications, especially in the 21st century. Regardless, many popular motorcycles and/or automobiles had three wheels. Examples 17th century *Stephan Farffler's trike 18th century * Cugnot's ''fardier à vapeur'' (steam powered) 19th century * Ariel 2.25 hp tricycle (1898) * Benz Pa ...

Ackermann Steering Geometry
The Ackermann steering geometry is a geometric arrangement of linkages in the steering of a car or other vehicle designed to solve the problem of wheels on the inside and outside of a turn needing to trace out circles of different radii. It was invented by the German carriage builder Georg Lankensperger in Munich in 1817, then patented by his agent in England, Rudolph Ackermann (1764–1834) in 1818 for horse-drawn carriages. Erasmus Darwin may have a prior claim as the inventor dating from 1758. He devised his steering system because he was injured when a carriage tipped over. Advantages The intention of Ackermann geometry is to avoid the need for tires to slip sideways when following the path around a curve. The geometrical solution to this is for all wheels to have their axles arranged as radii of circles with a common centre point. As the rear wheels are fixed, this centre point must be on a line extended from the rear axle. Intersecting the axes of the front wheels on th ...

Tie Rod
A tie rod or tie bar (also known as a hanger rod if vertical) is a slender structural unit used as a tie and (in most applications) capable of carrying tensile loads only. It is any rod or bar-shaped structural member designed to prevent the separation of two parts, as in a vehicle. Subtypes and examples of applications * In airplane structures, tie rods are sometimes used in the fuselage or wings. * Tie rods are often used in steel structures, such as bridges, industrial buildings, tanks, towers, and cranes. * Sometimes tie rods are retrofitted to bowing or subsiding masonry walls (brick, block, stone, etc.) to keep them from succumbing to lateral forces. * The rebar used in reinforced concrete is not referred to as a "tie rod", but it essentially performs some of the same tension-force-counteracting purposes that tie rods perform. * In automobiles, the ''tie rods'' are part of the steering mechanism. They differ from the archetypal tie rod by both pushing and pulling (operatin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Telescopic Fork
A telescopic fork is a form of motorcycle front suspension whose use is so common that it is virtually universal. The telescopic fork uses fork tubes and sliders which contain the springs and dampers. The main advantages of the telescopic fork are that (i) it is simple in design and relatively cheap to manufacture and assemble; (ii) it is lighter than older designs using external components and linkage systems; and (iii) it has a clean and simple appearance that bikers find attractive. Telescopic forks sometimes have gaiters to protect the fork tubes from abrasion and corrosion. A more modern (and more expensive) version of the conventional telescopic fork is the inverted or "USD" (upside-down) fork. BMW's patented telelever front suspension appears at first glance to be conventional telescopic fork, but the fork tubes contain neither springs nor damping. Instead, a wishbone and an inboard monoshock perform suspension duties, and the forks serve to locate the front wheel an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cantilever
A cantilever is a rigid structural element that extends horizontally and is supported at only one end. Typically it extends from a flat vertical surface such as a wall, to which it must be firmly attached. Like other structural elements, a cantilever can be formed as a beam, plate, truss, or slab. When subjected to a structural load at its far, unsupported end, the cantilever carries the load to the support where it applies a shear stress and a bending moment. Cantilever construction allows overhanging structures without additional support. In bridges, towers, and buildings Cantilevers are widely found in construction, notably in cantilever bridges and balconies (see corbel). In cantilever bridges, the cantilevers are usually built as pairs, with each cantilever used to support one end of a central section. The Forth Bridge in Scotland is an example of a cantilever truss bridge. A cantilever in a traditionally timber framed building is called a jetty or forebay. In the southe ...

Tilting Three-wheeler
A tilting three-wheeler, tilting trike, leaning trike, or even just tilter, is a three-wheeled vehicle and usually a narrow-track vehicle whose body and or wheels tilt in the direction of a turn. Such vehicles can corner without rolling over despite having a narrow axle track because they can balance some or all of the roll moment caused by centripetal acceleration with an opposite roll moment caused by gravity, as bicycles and motorcycles do. This also reduces the lateral acceleration experienced by the rider, which some find more comfortable than the alternative. The narrow profile can result in reduced aerodynamic drag and increased fuel efficiency. These types of vehicles have also been described as "man-wide vehicles" (MWV). As with tricycles that do not tilt, there are a variety of feasible choices of how the wheels are arranged, which wheels are steered, and which wheels are driven. In addition, there are a variety of feasible choices for which wheels tilt and whic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
