Green Laning
Off-roading is the activity of driving or riding in a vehicle on unpaved surfaces such as sand, gravel, riverbeds, mud, snow, rocks, and other natural terrain. Types of off-roading range in intensity, from leisure drives with unmodified vehicles, to competitions with customised vehicles and professional drivers. Off-roaders have been met with criticism for the environmental damage caused by their vehicles. There have also been extensive debates over the role of government in regulating the sport, including a Supreme Court case brought against the Bureau of Land Management in the United States. Off-road vehicle Travelling over difficult terrain requires vehicles capable of off-road driving such as ATVs. These vehicles have features designed specifically for use in off-road conditions such as extended ground clearance, off-road tires and a strengthened drive-train. Some manufacturers offer vehicles specifically designed for off-road use. Recreational off-roading Some exa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rallying
Rally is a wide-ranging form of motorsport with various competitive motoring elements such as speed tests (often called ''rally racing),'' 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 vehicles which must be road-legal if being used on open roads or specially built competition vehicles suited to crossing specific terrain. Rallying is typically distinguished from other forms of motorsport by not running directly against other competitors over laps of a circuit, but instead in a point-to-point format in which participants leave at regular intervals from one or more start points.

Range Rover Classic
The Range Rover Classic is a 4x4, mid-size Sport utility vehicle series produced from 1969 to 1996 – initially by the Rover (later Land Rover) division of British Leyland, and latterly by the Rover Group. The first generation of vehicles produced under the Range Rover name, it was built as a two-door model for its first 11 years, until a four-door also became available in 1981. The Range Rover then successfully moved upmarket during the 1980s, and remarkably debuted in the U.S. as a 17-year old model at the 1987 Los Angeles Auto Show. Availability of the two-door version was restricted from 1984, but it remained in production for some markets until 1994, when the second generation was launched. From that moment, Land Rover rebranded the original model under the term "Range Rover Classic", to distinguish it from its new P38A successor, when the two were briefly built alongside, and applied the name retrospectively to all first-generation Range Rovers. Although formally supers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Approach And Departure Angles
Approach angle is the maximum angle of a ramp onto which a vehicle can climb from a horizontal plane without interference. It is defined as the angle between the ground and the line drawn between the front tire and the lowest-hanging part of the vehicle at the front overhang. Departure angle is its counterpart at the rear of the vehicle – the maximum ramp angle from which the car can descend without damage. Approach and departure angles are also referred to as ramp angles. Approach and departure angles are indicators of off-road ability of the vehicle: they indicate how steep obstacles, such as rocks or logs, the vehicle can negotiate according to its body shape alone. See also * Breakover angle * Overhang (automotive) * Ride height Ride height or ground clearance is the amount of space between the base of an automobile tire and the lowest point of the automobile (typically the axle); or, more properly, to the shortest distance between a flat, level surface, and the lowe ...

Trial De Caille 2012 - Mickael Giraud & Tristan Simonis
In law, a trial is a coming together of parties to a dispute, to present information (in the form of evidence) in a tribunal, a formal setting with the authority to adjudicate claims or disputes. One form of tribunal is a court. The tribunal, which may occur before a judge, jury, or other designated trier of fact, aims to achieve a resolution to their dispute. Types by finder of fact Where the trial is held before a group of members of the community, it is called a jury trial. Where the trial is held solely before a judge, it is called a bench trial. Hearings before administrative bodies may have many of the features of a trial before a court, but are typically not referred to as trials. An appeal (appellate proceeding) is also generally not deemed a trial, because such proceedings are usually restricted to a review of the evidence presented before the trial court, and do not permit the introduction of new evidence. Types by dispute Trials can also be divided by the type of d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Road Tax
Road tax, known by various names around the world, is a tax which has to be paid on, or included with, a motorised vehicle to use it on a public road. National implementations Australia All states and territories require an annual vehicle registration fee to be paid in order to use a vehicle on public roads; the cost of which varies from state to state and is dependent on the type of vehicle. The fee is known colloquially as 'rego' (pronounced with a soft g, short for registration). Queensland road tax is based on the number of cylinders or rotors the vehicle's engine has. There is also a small traffic improvement fee. New South Wales road tax is paid based on the vehicle's tare weight. Belgium Passenger cars pay a registration fee based on the engine displacement and power output (degressive towards 2014 (66% in 2012, 33% in 2013, 0% in 2014) and environmental criteria such as CO2 g/km output (increasingly towards 2014). The more CO2 g/km the car produces, the higher the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spotter (maneuvering)
A spotter is a person used in vehicle maneuvers to assist a driver who may not have a clear view in their direction of travel. They are most commonly used in: * Off-road rock crawling * Reversing truck and trailer combinations, such as semitrailers, b-trains and road trains * Placing oversized freight using a forklift * Lifting loads using a vehicle-mounted crane (loads lifted using a fixed crane are supervised by a banksman In Irish and British civil engineering, a banksman is the person who directs the operation of a crane or larger vehicle from the point near where loads are attached and detached. The term 'dogman' may be used in Australia and New Zealand, while 's ...) * Guiding military vehicles (also called ''ground guiding'') * Dumping materials, such as from a dump truck * Guiding oversized loads. The spotter's advantage is the ability to move around the load or vehicle to determine the best trajectory. A spotter will either use a set of standard hand signals, or will a ...

Differential (mechanics)
A differential is a gear train with three drive shafts that has the property that the rotational speed of one shaft is the average of the speeds of the others, or a fixed multiple of that average. Functional description The following description of a differential applies to a traditional rear-wheel-drive car or truck with an open or limited slip differential combined with a reduction gearset using bevel gears (these are not strictly necessary; see spur-gear differential): Thus, for example, if the car is making a turn to the right, the main ring gear may make 10 full rotations. During that time, the left wheel will make more rotations because it has farther to travel, and the right wheel will make fewer rotations as it has less distance to travel. The sun gears (which drive the axle half-shafts) will rotate at different speeds relative to the ring gear (one faster, one slower) by, say, 2 full turns each (4 full turns relative to each other), resulting in the left wheel maki ...

Axle Articulation
Ramp travel index or RTI, is a way of measuring a vehicle's ability to flex its suspension, a property also known as axle articulation. The RTI rating is used mainly in the off-roading industry to test and describe chassis limits of modified vehicles. The ramps vary between 15 and 30 degrees of angle for the vehicle to ride up. "Ramping" a vehicle involves putting one front tire on the ramp and driving up slowly until one of the other three tires (usually the rear one on the same side as the tire driving the ramp) begins to leave the ground. The measurement is only taken when the other three tires are still on the ground. The distance traveled up the ramp is then measured and is divided by the vehicle's wheelbase and finally multiplied by 1000 to give a final RTI score. Most stock SUVs have RTI values from 400 to 550; vehicles modified for off-road competition have the ability to exceed 1000. Significance of RTI and Axle Articulation A high RTI or good axle articulation is es ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tires
A tire (American English) or tyre (British English) is a ring-shaped component that surrounds a Rim (wheel), wheel's rim to transfer a vehicle's load from the axle through the wheel to the ground and to provide Traction (engineering), traction on the surface over which the wheel travels. Most tires, such as those for automobiles and bicycles, are pneumatically inflated structures, which also provide a flexible cushion that absorbs shock as the tire rolls over rough features on the surface. Tires provide a footprint, called a contact patch, that is designed to match the weight of the vehicle with the bearing strength of the surface that it rolls over by providing a bearing pressure that will not deform the surface excessively. The materials of modern pneumatic tires are synthetic rubber, natural rubber, fabric, and wire, along with carbon black and other chemical compounds. They consist of a tire tread, tread and a body. The tread provides Traction (engineering), traction ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rock Crawling
Rock crawling is an extreme form of 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 " 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 The vehicles Vehicles commonly used include Jeep (the Chrysler and the Mitsubishi Varieties), Lada Niva, BAW, Nissan Patrol, Toyota Hilux, Toyota Land Cruiser, Land Rover, Merce ...
