ATV Fourcycle (from the Latin. "four", etc., Greek. "circle") - a vehicle with 4 wheels. Russia and the CIS, this word usually refers to ATVs 4 wheels (AVT - all terrain vehicle), the U.S. - 4-wheel bicycles.
The first ATV was released in 1970 - Honda US90 . This model has 3-wheel and with an extremely simple design (no suspension). This model was able to give birth to the fashion for ATVs. Later in the 80's of the 20th century, virtually all ATVs are designed to have 4-wheel base.
now (according to experts) ATV market is more than 2 million copies a year. Most of the sales have quads on America. Recently, quite significantly grow the European and Asian markets. Scale ATV sales are increasing. ATV now produce not only the company, proven in the motorcycle industry, but also a large Number of Asian firms. Russia also introduced production ATVs.
first four-AVT, appeared about 30 years ago, very little is fundamentally different from the current models. Over time appeared disc brakes, automatic clutch, independent suspension, water-cooled engines, and other improvements of parts and materials. In addition, over time, under the influence of market demand, began to appear more and more powerful ATV. So instead of the old 4-stroke single-cylinder motors of small volume (250-300 cu. Cm) and power (15-22 hp) started coming athletes with a hundred or more horses.
So the same time there was some (albeit quite arbitrary) division ATV-ATV on utilitarian, sports, travel, play and recreational AVT.
Utility AVT
Originally ATVs designed for utilitarian use. Current models of ATV in its class, serve the same purpose: a reliable assistant in agriculture (an alternative to mini-tractors and specialized equipment). For their work, there are a surprising number of attachments (plows, planters, buckets and knives dumps for snow removal, trailers, etc.). Also, these are very solid AVT hodovku with dependent rear suspension and independent front. Engine well as to be a very reliable and powerful (there are both 2 and 4-stroke models).
Dear representatives equipped liquid cooling engine. Often, to perform their job functions, utilitarian AVT have a manual transmission, more sophisticated models are equipped with V-belt CVT. In addition, usually these ATVs are equipped with a large trunk, front and rear baskets.
Travel AVT
Existing special AVT for use in off-road conditions, wetlands and forest areas, so-called "hunting" or travel ATVs. These ATVs are usually 4-stroke engines with automatic transmissions and increased suspension travel. In addition, they have a high ground clearance and low-pressure tires, which makes it easy to overcome wetlands. Other signs of this all-terrain vehicle in these ATV include all-wheel drive (Most of models in this class), a lower gear and locking differentials.
Sports AVT
This type of ATV has long-travel suspension that can withstand hard landing after prizhkov. The motors are designed for high-speed driving, so have over 50 hp and liquid cooling.
Typically, these ATVs are equipped with a manual sports transmission . speed sport ATV can privyshat 140 km /h, which requires extensive training and pilot training . AVT foolhardiness in sports often leads to accidents and deaths. As motocross bike (enduro), sports AVT require similar special equipment.
Baby AVT
For the young, novice drivers (12-15 years), there are children AVT, which are small-scale replicas of conventional ATVs. Kids ATVs are usually designed for loads up to 60 kg of speeds up to 50 km /h On some children's quad bike no suspension. Its functions are performed by a special low-pressure tires.
Walking AVT
Playgroup ATVs are between children's quad bikes and travel. They are easy to manage, cost-effective and do not require special skills to operate. Their thickness is not much more
