Off-road
Off-roading is the act of driving or riding in a vehicle on unpaved surfaces such as sand, dirt, gravel, riverbeds, mud, snow, rocks, or other natural terrain. Off-roading ranges from casual drives with regular vehicles to competitive events with customized vehicles and skilled drivers. Off-road vehicle Off-road vehicles are either capable of or specifically developed for off-road driving. These vehicles often have features designed specifically for use in off-road conditions such as suspension lifts, off-road tires, skid plates, snorkels, roll cages, or strengthened drivetrains. Types of recreational off-roading Dune bashing Dune bashing is a specific form of off-roading performed on sand dunes. Dune Buggies, Sport-utility vehicles, and ATVs are often used. Vehicles driven on sand dunes are often equipped with a roll cage for safety in the case of an overturn. The tire pressure is often reduced to gain more traction by increasing the footprint of the tire ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sport Utility Vehicle
A sport utility vehicle (SUV) is a car classification that combines elements of road-going passenger cars with features from off-road vehicles, such as raised ground clearance and four-wheel drive. There is no commonly agreed-upon definition of an SUV, and usage of the term varies between countries. Thus, it is "a loose term that traditionally covers a broad range of vehicles with four-wheel drive." Some definitions claim that an SUV must be built on a light truck chassis; however, broader definitions consider any vehicle with off-road design features to be an SUV. A crossover SUV is often defined as an SUV built with a unibody construction (as with passenger cars); however, the designations are increasingly blurred because of the capabilities of the vehicles, the labelling by marketers, and the electrification of new models. The predecessors to SUVs date back to military and low-volume models from the late 1930s, and the four-wheel-drive station wagons and carryalls that b ...

Motorsport
Motorsport or motor sport are sporting events, competitions and related activities that primarily involve the use of Car, automobiles, motorcycles, motorboats and Aircraft, powered aircraft. For each of these vehicle types, the more specific terms ''automobile sport'', ''motorcycle sport'', Motorboat#Racing, ''power boating'' and ''air sports'' may be used commonly, or officially by organisers and governing bodies. Different manifestations of motorsport with their own objectives and specific rules are called disciplines. Examples include Race track, circuit racing, rallying and Classic trial, trials. Governing bodies, also called sanctioning bodies, often have general rules for each discipline, but allow supplementary rules to define the character of a particular competition, series or championship. Groups of these are often categorised informally, such as by vehicle type, surface type or propulsion method. Examples of categories within a discipline are formula racing, stock car r ...

Off-road Tire
Off-road tires (Off-road tyre) are a category of vehicle tires that use deep tread to provide more traction on unpaved surfaces such as loose dirt, mud, sand, or gravel. Compared to ice or snow tires, they lack studs but contain deeper and wider grooves meant to help the tread sink into mud or gravel surfaces. Design Off-road tires are typically radials with thick, deep tread. On dirt surfaces, the exposed edges of the tread dig into soft ground to give more traction than rolling friction alone, analogous to the traction provided by cleated shoes. These off-road tires provide their maximum grip on loose surfaces, but on paved surfaces the smaller contact patch affords less traction as compared to street tires. Tires with less aggressive knobs (smaller knobs and the shape of the tread cross-section closer to that of street tires) can provide a compromise, giving less grip off-road, but a grip closer to that of street tires on paved surfaces. Such tires are useful for enduro an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
All-terrain Vehicle
An all-terrain vehicle (ATV), also known as a light utility vehicle (LUV), a quad bike or quad (if it has four wheels), as defined by the American National Standards Institute (ANSI), is a vehicle that travels on low-pressure tires, has a seat that is straddled by the operator, and has handlebars, similar to a motorcycle. As the name implies, it is designed to handle a wider variety of terrain than most other vehicles. It is street-legal in some countries, but not in most states, territories and provinces of Australia, the United States, and Canada. By the current ANSI definition, ATVs are intended for use by a single operator, but some ATVs, referred to as tandem ATVs, have been developed for use by the driver and one passenger. The rider sits on and operates these vehicles like a motorcycle, but the extra wheels give more stability at slower speeds. Although most are equipped with three or four wheels, six or eight wheel (tracked) models exist and have existed historicall ...

Beadlock
A beadlock or bead lock is a mechanical device that secures the bead of a tire to the wheel of a vehicle. Tires and wheels are designed so that when the tire is inflated, the tire pressure pushes the bead of the tire against the inside of the wheel rim so that the tire stays on the wheel and the two rotate together. In situations where tire pressure is insufficient to hold the bead of the tire in place, a beadlock is needed. There are several styles of beadlocks. For four-wheel drive vehicles, a ring with a number of bolts around the circumference can be used to clamp the tire to the wheel. For motorcycles, a rim lock or bead stopper is a curved plate tightened by a single bolt. For both four-wheel drive vehicles and motorcycles, a different style of beadlock can be used that is similar to an inner tube which is inflated to press the tire against the wheel. History Dodge Military trucks had the first beadlocks, called Combat Wheels; the 'combat wheels' were a divided-rim, that ...

Rallying
Rallying is a wide-ranging form of motorsport with various competitive motoring elements such as speed tests (sometimes called "rally racing" in United States), navigation tests, or the ability to reach waypoints or a destination at a prescribed time or average speed. Rallies may be short in the form of trials at a single venue, or several thousand miles long in an extreme endurance rally. Depending on the format, rallies may be organised on private or public roads, open or closed to traffic, or off-road in the form of cross country or rally-raid. Competitors can use Production vehicle, production vehicles which must be Street-legal vehicle, road-legal if being used on open roads or specially built competition vehicles suited to crossing specific terrain. In most cases rallying distinguishes itself from other forms of motorsport by not running directly against other competitors over laps of a Race track, circuit, but instead in a point-to-point format in which participants leave ...

Rock Crawling
Rock crawling is an extreme form of Off-roading, off-road driving using specialized vehicles ranging from stock to highly modified, to overcome obstacles. In rock crawling, drivers typically drive highly modified four-wheel-drive vehicles such as trucks, Jeeps, and "Buggy (automobile), buggies" over very harsh terrain. Driving locations include boulders, mountain foothills, rock piles, mountain trails, etc. Rock crawling is about slow-speed, careful and precise driving, and high torque generated through large gear reductions (100:1 or more) in the vehicle's drivetrain. Rock crawlers often drive up, down and across obstacles that appear impassable. Rock crawling competitions range from local events to national series. These consist of long courses with obstacles set up with gates, similar to a slalom ski race. Rock crawling basics Vehicles Vehicles commonly used include Jeep (the Chrysler and the Mitsubishi Varieties), Lada Niva, BAW, Nissan Patrol, Toyota Hilux, Toyota Land ...

Unimog U1600
The Unimog (pronunciation in American English: ''YOU-nuh-mog''; British English: ''YOU-knee-mog''; German: , ) is a Daimler Truck line of multi-purpose, highly offroad capable AWD vehicles produced since 1948. Utilizing engine-driven power take-offs (PTO) Unimogs have operated in the roles of tractors, light trucks and lorries, for snow plowing, in agriculture, forestry, rural firefighting, in the military, even in rallying and as recreational vehicles. The frame is designed to be a flexible part of the suspension, not to carry heavy loads. Overview Conceived in 1944 in response to the Morgenthau Plan, former Daimler-Benz airplane engine engineers developed prototypes under occupation. The small universally-applicable motorised 25hp workhorse was designed to be able to fit over two rows of potatoes to work on fields like a slow agricultural tractor, but with four equal size wheels on portal axles, coil spring suspension, and many gears allowing it to run on roads like a truck ...

Skid Plate
A skid plate is an abrasion-resistant material affixed to the underside of a vehicle or boat to prevent damage to the underside when contact is made with the ground. Skid plates may be used on off-road Off-roading is the act of driving or riding in a vehicle on unpaved surfaces such as sand, dirt, gravel, riverbeds, mud, snow, rocks, or other natural terrain. Off-roading ranges from casual drives with regular vehicles to competitive events w ... vehicles, motorcycles and lowered vehicles to prevent damage to the underside. Fake skid plates are also added to vehicles for an off-road look. Steel skid plate for the protection of the engine and the gearbox. The advantages: * Increased resistance against any impact or debris found on the road. * It covers the front compartment of the car, so the engine is more protected against dust and dirt. * Longer lifespan compared to skid plates made of plastic or fibre glass. * It protects the frame, motor and linkage on an off-road m ...

Vehicle Rollover
A rollover or overturn is a type of vehicle crash in which a vehicle tips over onto its side or roof. Rollovers have a higher fatality rate than other types of vehicle collisions. Dynamics Vehicle rollovers are divided into two categories: tripped and untripped. Tripped rollovers are caused by forces from an external object, such as a curb or a collision with another vehicle. Untripped rollovers are the result of steering input, speed, and friction with the ground. Trailers that are not roll-coupled (i.e. those that use a trailer coupling rather than a fifth wheel) are more prone to rolling as they do not have the tractor unit or prime mover for additional stability. Untripped rollovers Untripped rollovers occur when cornering forces destabilize the vehicle. As a vehicle rounds a corner, three forces act on it: tire forces (the centripetal force), inertial effects (the centrifugal force), and gravity. The cornering forces from the tire push the vehicle towards the center of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Car Suspension
Suspension is the system of tires, tire air, spring (device), springs, shock absorbers and Linkage (mechanical), linkages that connects a vehicle to its wheels and allows relative motion between the two. Suspension systems must support both road holding/Automobile handling, handling and ride quality, which are at odds with each other. The tuning of suspensions involves finding the right compromise. The suspension is crucial for maintaining consistent contact between the road wheel and the road surface, as all forces exerted on the vehicle by the road or ground are transmitted through the tires' contact patches. The suspension also protects the vehicle itself and any cargo or luggage from damage and wear. The design of front and rear suspension of a car may be different. History An early form of suspension on ox-drawn carts had the platform swing on iron chains attached to the wheeled frame of the carriage. This system remained the basis for most suspension systems unti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dune Buggy
A dune buggy — also known as a beach buggy — is a recreational off-road vehicle with large wheels, and wide tires, designed for use on sand dunes, beaches, off-road or desert recreation. The design is usually a topless vehicle with a rear-mounted engine. A dune buggy can be created by modifying an existing vehicle or custom-building a new vehicle. Design Dune buggies are typically created by modifying an existing road vehicle, while sandrails are built from the ground up as a custom vehicle. Beetle-based buggies For dune buggies built on the chassis of a rear-engined existing vehicle, the Volkswagen Beetle has been most commonly used as the basis for the buggy, though conversions were made from other rear-engined cars (such as the Corvair and Renault Dauphine). The model is nicknamed Bug, lending partial inspiration to the term "buggy." The Beetle platform chassis was used because the rear engine layout improves traction, the air-cooled engine avoids the complexi ...
