Allvelo
Allvelo (Allmänna Velocipedförsäljnings AB) was a company founded by Fritiof Karlström in Landskrona, Sweden. The company began by importing bicycles, but soon decided to purchase unassembled Waltham Orient buckboards from the United States. These they assembled and sold as All-Velos under the names Allvelo Orient and Allvelo Pansarmobil Sport. All told, probably around 50 were assembled. Most parts other than the steering, axles, and engines were of wood. Each car had a single-cylinder air-cooled engine mounted at the rear, with friction drive. Brakes were fitted on the right rear wheel only, and the cars had tiller steering. Other models Other models assembled included the French Orel, as Allvelo Orel, and a UK made truck, under the name Allvelo Vulcan. In 1907 they made a prototype car A car or automobile is a motor vehicle with wheels. Most definitions of ''cars'' say that they run primarily on roads, seat one to eight people, have four wheels, and mainly t ...

Friction Drive
A friction drive or friction engine is a type of transmission that utilises two wheels in the transmission to transfer power from the engine to the driving wheels. The system is naturally a continuously variable transmission; by moving the two disks' positions, the output ratio changes continually. Although once used in early automobiles, today the system is most commonly used on scooters, mainly go-peds, in place of a chain and gear system. It is mechanically identical to a ball-and-disk integrator, but intended to handle higher torque levels. The system consists of two disks, normally metal, set at right angles to each other. One disk is connected to the engine, the other to the load. The load disk is positioned so that its outer rim is pressed against the driven disk, and normally has some sort of high-friction surface applied to the outer rim to improve torque transfer. In early systems, paper and leather was often used for this surface. One of the disks, normally the load ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Landskrona
Landskrona (old da, Landskrone) is a town in Scania, Sweden. Located on the shores of the Öresund, it occupies a natural port, which has lent the town at first military and subsequent commercial significance. Ferries operate from Landskrona to the island of Ven, and for many years there was also a connection to Copenhagen. Landskrona is part of the Øresund region. It is the seat of Landskrona Municipality. Landskrona is also the name of a district in Landskrona Municipality which is slightly smaller than the urban area. History The city of Landskrona is usually claimed to have been founded in 1413 by the King of Denmark, Eric of Pomerania, as a trading city intended to compete with Danish towns under the control of the Hanseatic League. There is however evidence found in the Danish National Archive, which mention the town by the name "Landzcrone" already in 1405. The site occupies one of a few natural harbours in Scania, which at that time was part of Denmark. At the tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bicycles
A bicycle, also called a pedal cycle, bike or cycle, is a human-powered or motor-powered assisted, pedal-driven, single-track vehicle, having two wheels attached to a frame, one behind the other. A is called a cyclist, or bicyclist. Bicycles were introduced in the 19th century in Europe. By the early 21st century, more than 1 billion were in existence. These numbers far exceed the number of cars, both in total and ranked by the number of individual models produced. They are the principal means of transportation in many regions. They also provide a popular form of recreation, and have been adapted for use as children's toys, general fitness, military and police applications, courier services, bicycle racing, and bicycle stunts. The basic shape and configuration of a typical upright or "safety bicycle", has changed little since the first chain-driven model was developed around 1885. However, many details have been improved, especially since the advent of modern ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buckboard
A buckboard is a four-wheeled wagon of simple construction meant to be drawn by a horse or other large animal. A distinctly American utility vehicle, the buckboard has no springs between the body and the axles. The suspension is provided by the flexible floorboards of the body and a leaf spring under the seat(s). The buckboard has no sideboards on the body, leaving the floor quite mobile. In rough terrain, the floor can flex and "buck", lending the vehicle its name. The buckboard is steered by its front wheels, which are connected by a single axle. The front and rear axle are connected by a platform of one or more boards to which the front axle is connected on a pivoting joint at its midpoint. A buckboard wagon often carries a seat for a driver. Such a seat may be supported by springs. The main platform between axles is not suspended by springs like a carriage. Invention The buckboard was invented by Reverend Cyrus Comstock, a traveling preacher living in Lewis, Essex County ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Single-cylinder
A single-cylinder engine, sometimes called a thumper, is a piston engine with one cylinder. This engine is often used for motorcycles, motor scooters, go-karts, all-terrain vehicles, radio-controlled vehicles, portable tools and garden machinery (such as lawnmowers, cultivators, and string trimmers). Single-cylinder engines are made both as 4-strokes and 2-strokes. Characteristics Compared with multi-cylinder engines, single-cylinder engines are usually simpler and compact. Due to the greater potential for airflow around all sides of the cylinder, air cooling is often more effective for single cylinder engines than multi-cylinder engines. This reduces the weight and complexity of air-cooled single-cylinder engines, compared with liquid-cooled engines. Drawbacks of single-cylinder engines include a more pulsating power delivery through each cycle and higher levels of vibration. The uneven power delivery means that often a single-cylinder engine requires a heavier flywheel than a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air-cooled
Air-cooled engines rely on the circulation of air directly over heat dissipation fins or hot areas of the engine to cool them in order to keep the engine within operating temperatures. In all combustion engines, a great percentage of the heat generated (around 44%) escapes through the exhaust, not through the metal fins of an air-cooled engine (12%). About 8% of the heat energy is transferred to the oil, which although primarily meant for lubrication, also plays a role in heat dissipation via a cooler. ''Air-cooled engines'' are used generally in applications which would not suit liquid cooling, as such modern air-cooled engines are used in motorcycles, general aviation aircraft, lawn mowers, generators, outboard motors, pump sets, saw benches and auxiliary power units. Introduction Most modern internal combustion engines are cooled by a closed circuit carrying liquid coolant through channels in the engine block and cylinder head, where the coolant absorbs heat, to a heat ...

Brake
A brake is a mechanical device that inhibits motion by absorbing energy from a moving system. It is used for slowing or stopping a moving vehicle, wheel, axle, or to prevent its motion, most often accomplished by means of friction. Background Most brakes commonly use friction between two surfaces pressed together to convert the kinetic energy of the moving object into heat, though other methods of energy conversion may be employed. For example, regenerative braking converts much of the energy to electrical energy, which may be stored for later use. Other methods convert kinetic energy into potential energy in such stored forms as pressurized air or pressurized oil. Eddy current brakes use magnetic fields to convert kinetic energy into electric current in the brake disc, fin, or rail, which is converted into heat. Still other braking methods even transform kinetic energy into different forms, for example by transferring the energy to a rotating flywheel. Brakes are generally ...

Tiller
A tiller or till is a lever used to steer a vehicle. The mechanism is primarily used in watercraft, where it is attached to an outboard motor, rudder post or stock to provide leverage in the form of torque for the helmsman to turn the rudder. A tiller may also be used in vehicles outside of water, and was seen in early automobiles. On vessels, a tiller can be used by the helmsman directly pulling or pushing it, but it may also be moved remotely using tiller lines or a ship's wheel. Rapid or excessive movement of the tiller results in an increase in drag and will result in braking or slowing the boat. Description A tiller is a lever used to steer a vehicle. It provides leverage in the form of torque to turn the device that changes the direction of the vehicle, such as a rudder on a watercraft or the surface wheels on a wheeled vehicle. A tiller can be used by directly pulling or pushing it, but it may also be moved remotely using tiller lines or a ship's wheel; some kayaks wh ...

Truck
A truck or lorry is a motor vehicle designed to transport cargo, carry specialized payloads, or perform other utilitarian work. Trucks vary greatly in size, power, and configuration, but the vast majority feature body-on-frame construction, with a cabin that is independent of the payload portion of the vehicle. Smaller varieties may be mechanically similar to some automobiles. Commercial trucks can be very large and powerful and may be configured to be mounted with specialized equipment, such as in the case of refuse trucks, fire trucks, concrete mixers, and suction excavators. In American English, a commercial vehicle without a trailer or other articulation is formally a "straight truck" while one designed specifically to pull a trailer is not a truck but a "Tractor unit, tractor". The majority of trucks currently in use are still powered by diesel engines, although small- to medium-size trucks with gasoline engines exist in the US, Canada, and Mexico. The market-share of ...
