Monowheel Tractors
A monowheel or uniwheel is a type of one-wheeled, single-track vehicle. Unlike the unicycle, a monowheel consists of a large, hollow wheel that loops above and around the driver. Monowheels are typically powered by an engine as with a motorcycle, with a chassis securing the steering, driver's seat, and propulsion mechanism to the interior of the wheel. Hand-cranked and pedal-powered monowheels were patented and built in the late 19th century; most built in the 20th and 21st century have been motorized. Some modern builders refer to these vehicles as monocycles, though that term is also sometimes used to describe motorized unicycles. A world speed record for a motorized monowheel was set in 2016, at 98.464 km/h (61.18 mph). Stability Similar to bicycles, monowheels are stable in the direction of travel, but have limited horizontal stability. This is in contrast to unicycles which are unstable in both directions. Monowheels have also been found to have a lower speed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dynasphere (vehicle)
The Dynasphere (sometimes misspelled Dynosphere) is a monowheel vehicle design patented in 1930 by John Archibald Purves FRSE (7 August 1870 – 4 November 1952) from Taunton, Somerset, UK. Purves' idea for the vehicle was inspired by a sketch made by Leonardo da Vinci. Design Two prototypes were initially built: a smaller electrical model, and one with a gasoline motor that attained either 2.5 or 6 horsepower depending on the source consulted, using a two-cylinder air-cooled Douglas engine with a three speed gear box, also providing reverse. The Dynasphere model reached top speeds of . The gasoline-powered prototype was high and built of iron latticework that weighed . The next generation version had ten outer hoops, covered with a leather lining, shaped to present a small profile to the ground. The driver's seat and the motor were part of one unit, mounted with wheels upon the interior rails of the outer hoop. The singular driving seat and motor unit, when powered ...

List Of Star Wars Air, Aquatic, And Ground Vehicles
The following is a list of fictional ''Star Wars'' terrestrial vehicles, including armored fighting vehicles, military aircraft, and naval ships. The ''Star Wars'' universe showcases a diversity of vehicle types, many of which utilize fictitious technology. One of these, the repulsorlift, is an anti-gravity device that pushes against a planet's gravity to create lift. Vehicles which use repulsorlifts to hover and fly are known as 'repulsorcraft' or 'speeders' with further classifications including airspeeders, landspeeders, snowspeeders and speeder bikes.Barr, et al. (2017), p. 188-189Dougherty, et al.

Dicycle (vehicle)
A dicycle () (also known as a diwheel) is a vehicle with two parallel wheels, side by side, unlike single-track vehicles such as motorcycles and bicycles, which have two wheels inline. Originally used to refer to devices with large wheels and pedals, the term is now used in relation to powered Personal transporter#Self-balancing_scooter, self-balancing scooters with smaller wheels and no pedals such as the Segway PT and the self-balancing scooter, self-balancing hoverboard. Etymology In more recent usage, "dicycle" has been used for both pedaled and motorised vehicles with wheels of varying sizes, as long as they share a common Rotation around a fixed axis, axis, though not necessarily a common axle. In 2017, the Merriam-Webster's dictionary, limited usage to 'velocipedes with two parallel wheels,' and the Oxford English Dictionary limited it to 'pedal-powered vehicles with large wheels placed parallel to each other'. Examples Segway PT The Segway PT is a two-wheeled self-balancin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sprocket
A sprocket, sprocket-wheel or chainwheel is a profiled wheel A wheel is a rotating component (typically circular in shape) that is intended to turn on an axle Bearing (mechanical), bearing. The wheel is one of the key components of the wheel and axle which is one of the Simple machine, six simple machin ... with teeth that mesh with a chain, rack and pinion, rack or other perforated or indented material. The name 'sprocket' applies generally to any wheel upon which radial projections engage a chain passing over it. It is distinguished from a gear in that sprockets are never meshed together directly, and differs from a pulley in that sprockets have teeth and pulleys are smooth except for timing pulleys used with toothed belts. Sprockets are used in bicycles, motorcycles, continuous track, tracked vehicles, and other machinery either to transmit rotary motion between two shafts where gears are unsuitable or to impart linear motion to a track, tape etc. Perhaps the most commo ...

Burning Man
Burning Man is a week-long large-scale desert event focused on "community, art, self-expression, and self-reliance" held annually in the Western United States. The event's name comes from its ceremony on the penultimate night of the event: the symbolic burning of a large wooden effigy, referred to as the Man, the Saturday evening before Labor Day. Since 1990, the event has been at Black Rock City in northwestern Nevada, a temporary city erected in the Black Rock Desert about north-northeast of Reno, Nevada, Reno. According to Burning Man co-founder Larry Harvey in 2004, the event is guided by ten stated principles: radical inclusion, Gift Economy, gifting, decommodification, radical self-reliance, radical self-expression, communal effort, Civic engagement, civic responsibility, Leave no trace, leaving no trace, participation, and immediacy. Burning Man features no headliners or scheduled performers; participants create all the art, activities, and events. Artwork includes exper ...

RIOT Wheel
A RIOT wheel is a one-wheeled vehicle, or monowheel. A motor and counterweight are housed inside a giant wheel, while the driver sits on a platform that extends out in front of the device. This is in contrast to the more typical monowheels and their long history, where the rider sits ''inside'' the wheel. By moving the wheel's center of gravity forward, the wheel turns. Inside is a lead-weighted engine, which hangs by bearings off a stationary center shaft and uses its torque to move from 0 degrees vertical when stationary to 90 degrees forward at full blast, continually pulling itself forward around a sprocket bolted to the outer spokes. An independent counterweight system keeps the driver floating gently above ground from the front, instead of inside the wheel, where most monowheel designs position them. Steering is handled by a gyroscopic system and the driver's shifting weight. History Part-time programmer and Renaissance Fair jouster Jake Lyall had never worked for a garage ...

Tank
A tank is an armoured fighting vehicle intended as a primary offensive weapon in front-line ground combat. Tank designs are a balance of heavy firepower, strong armour, and battlefield mobility provided by tracks and a powerful engine; their main armament is often mounted within a turret. They are a mainstay of modern 20th and 21st century ground forces and a key part of combined arms combat. Modern tanks are versatile mobile land weapons platforms whose main armament is a large- calibre tank gun mounted in a rotating gun turret, supplemented by machine guns or other ranged weapons such as anti-tank guided missiles or rocket launchers. They have heavy vehicle armour which provides protection for the crew, the vehicle's munition storage, fuel tank and propulsion systems. The use of tracks rather than wheels provides improved operational mobility which allows the tank to overcome rugged terrain and adverse conditions such as mud and ice/snow better than wheele ...
