For four-wheeled vehicles (and by extension, vehicles with six, eight, or more wheels), this term is used to describe vehicles that are able to power at most two wheels, referred to as either front, or rear-wheel-drive. The term 4x2 is also used, to denote four total wheels with two being driven. Most road vehicles use a 2WD layout due to its ...
A screw-propelled vehicle. A screw-propelled vehicle is a land or amphibious vehicle designed to cope with difficult terrain, such as snow, ice, mud, and swamp. Such vehicles are distinguished by being moved by the rotation of one or more auger-like cylinders fitted with a helical flange that engages with the medium through or over which the vehicle is moving.
Snow chains should be installed on one or more drive axles of the vehicle, with requirements varying for dual-tire or multi-driven-axle vehicles that range from "one pair of tires on a driven axle" to "all tires on all driven axles", possibly also one or both steering (front) wheels, requiring snow chains whenever required by signage or conditions.
In contrast, the M29 was a front engine, rear wheel drive vehicle with a different bogie wheel arrangement and a modified hull to accommodate a larger passenger/load capacity. One of the most obvious differences between the M28 and M29 is that the M29's idler wheel, located at the front of the vehicle, is lower than the drive sprocket at the ...
The main advantage of half-tracks over wheeled vehicles is that the tracks reduce the pressure on any given area of the ground by spreading the vehicle's weight over a larger area, which gives it greater mobility over soft terrain like mud and snow, while they do not require the complex steering mechanisms of fully tracked vehicles, relying instead on their front wheels to direct the vehicle ...
Air drag is most significant for high-speed events; as of 2016, the world record for a 200-metre sprint on near-level ground is about 145 km/h for a two-wheel streamliner and about 120 km/h for any vehicle with more than two wheels, [18] meaning the two-wheel vehicle was about 20% faster. Aerodynamic power is roughly cubic in speed, so at lower ...
In contrast to today's ANSI definition of an ATV: "a vehicle that travels on low pressure tires, with a seat that is straddled by the (single) operator, and with handlebars for steering control", an AATV is intended for multiple riders, sitting inside, and will usually have two control sticks (and in some cases a steering wheel or joystick ...
