"Sherp" - what is this? Off-road vehicle "Sherp"

As a ship you will name, so it will float. The name "Sherp" for different types of vehicles on wheels speaks for itself.

The nominal value

Sherp - what is it? In the first of the nominal values, after all, not "what", but "who." Sherp is a person who is paving the way for someone. There was this definition in the XIX century, when English expeditions needed to study the Himalayas porters and guides. For this role, the hardy and brave Sherpas suited.

This small nationality lives at the foot of Jomolungma and Khumbu on the border with Tibet, at an altitude of 3000-4000 meters above sea level. Sherpas came to these areas from Eastern Tibet. The name of this people is in Tibetan and means "a man from the east".

In Nepal Sherpas are engaged in cattle breeding and agriculture, and in India - trade and still climbing the mountain peaks as porters and guides.

Sherpa's technique

The reputation of Sherpas was used more than once by the manufacturers of off-road vehicles.

"Kawasaki Sherpa" is a Japanese double-purpose motorcycle that can travel not only along roads, but also over rough terrain. He appeared in 1997, first in Japan's own market, and then in the US, Canada, Greece, Australia, the United Kingdom and New Zealand.

This is a low weight motorcycle (average 120 kg), easy to drive, small in seat height (810 mm), but has a high ground clearance (265 mm).

"Alpina Sherpa" is a snowmobile, which fully corresponds to its name. It was designed to work in high-mountain resorts, but it is suitable for rescuers, avalanche service, forest patrols.

It can transport injured skiers, tow a group of skiers to the lift in places without lifts, lay trails on deep snowdrifts for sports snowmobiles or skiers-runners. This snowmobile is called unique. He, unlike other models, has two tracks with a total width of one meter. All of its systems are extremely reliable and controlled by the driver. It is impossible to drive at high speeds on an Italian snowmobile, its maximum speed is 50 km / h, but it can overcome almost sheer climbs, albeit leisurely, but confidently.

Off-road vehicle "Sherp" Garagashyan

Alexey Garagashyan, a talented structural engineer from St. Petersburg, called Sherp his new offspring, a low-pressure all-terrain vehicle, which was released no later than 2015.

The off-roader "Sherp" combines patency, maneuverability, reliability, compactness and a large interior.

This machine provides complete freedom of action. She is not afraid of obstacles up to one meter high, steep slopes, and it does not matter what is under the wheels: water, peat, hard ground or ice.

On cross-country, experts compare the "Sherp" with caterpillar equipment, and sometimes not in favor of the latter. Almost absolute permeability to the machine is provided by original technical solutions and the experience gained, which A. Garagashyan used in its design.

All-terrain vehicle characteristics

Length 3,4 m, width 2,5 m, height 2,8 m - dimensions of the all-terrain vehicle "Sherp". What does this mean? The machine is very compact. Thus the road gleam depending on pressure in tires reaches 60 cm.

The maximum speed that Sherp develops on the road is not more than 45 km / h, and the minimum speed is 1.5 km / h. In water bodies of any depth, the speed of the all-terrain vehicle is 6 km / h.

The capacity of the main fuel tank is 58 liters, and it spends 2-3 liters per hour of diesel fuel, depending on the complexity of the route. If you need a larger power reserve, you can install additional tanks in the wheel disks for another 50 liters.

The ATV can carry a weight of a half tonne weight without reducing the cross-country ability and tow almost two and a half tons, while the speed drops to 30 km / h.

Kubota V1505-t turbo diesel engine in volume of 1,5 l and capacity of 44 hp. Together with the usual mechanical five-speed gearbox is installed deep enough under the front seat. This feature of the design of the all-terrain vehicle "Sherp". What does this give? The center of gravity of the machine is extremely shifted downwards, which protects it from overturning.

Chassis construction

The main feature of the all-terrain vehicle attracts attention from the first sight. Huge wheels of a height of 1.6 meters and a width of 0.6 m can not be seen, but this is not their only advantage. Ultra-low pressure tires are equipped with an automatic pumping system, for monitoring which a special pedal is placed in the salon.

Wheel disks are designed specifically for the Sherp all-terrain vehicle. What does this give? The disks ensure the retention of the tire at low pressure, and their design is designed so that the dirt does not stick on them and does not intend to ice.

Exhaust gases are fed into the tires. To pump the tires to operating pressure when starting the engine, it will take no more than 15 seconds.

The axles of the wheels rigidly attached to the body, not being able to move, including vertically. Therefore, in the all-terrain vehicle, a pneumatic circulation suspension of a new original design is used, in which air can move through a system of pipes of a sufficiently large diameter from the wheel under which the obstacle was placed into the remaining wheels.

All-terrain vehicle arrangement

The body of the all-terrain vehicle is inscribed between the wheels. The cab with car seats equipped with seat belts for the driver and one passenger is located in its front part, behind it is a cargo platform, curved wings over the wheels are connected by jumpers.

Transmission in the "Sherp" not only transmits torque to the wheels, but also with the help of chains of drives of wheels that are in the body, controls the machine.

The controls of the all-terrain vehicle are the levers connected to the drives of the onboard brakes, the manual gearbox, the clutch pedals and the gas.

To control the pressure of the tires there is not only a pedal, but also a device that is a usual tonometer for physicians.

There are not many devices, they are familiar with drivers, except the hour meter. This device is necessary, because THAT needs to pass through every 50 operating hours.

Doors in the all-terrain vehicle "Sherp" are not provided. The cabin can be accessed via the folding door-ramp in the front sheet of the shell, relying on a special tubular footrest. In this case, the front window flaps in the hinges. The side windows can also be lifted and fixed, like the frontal, in any position.

Complete sets of cross-country vehicle

Today, the all-terrain vehicle is produced at the Obukhov plant in St. Petersburg in two trim levels.

Basic equipment "Standard" is produced with a fabric tent, wheel hoods, three batteries, halogen optics, extra-strong body painting, a liquid interior heater and heat- and -noise insulation of the engine compartment.

The "Kung" package is characterized by a warm, transformable, soft cabin. It can move 6 people, and comfortably sleep in full growth two.

Additional options that can be equipped with an all-terrain vehicle at the request of the buyer are LED lights, an air heater, a generator for 60 A, additional fuel tanks and a uniaxial trailer, on which the all-terrain vehicle can be transported for long distances.

On the all-terrain vehicle "Sherp" the price fluctuates between 3.85-4.1 million rubles. Depending on the configuration without additional options.

Test drive all-terrain vehicle

For this kid on the giant wheels do not need a road, absolutely no road is needed. It can easily climb up and down a steep slope very stably (with fuel being supplied to the engine continuously), calmly move through fallen trees and piles of stones.

The total displacement of the wheels is almost three and a half tons, the hull is about a ton. That is, the total displacement of a waterfowl is a little less than five tons. If we take into account that the dry mass of the all-terrain vehicle is 1.3 tons, and the cargo can take a ton, the reserve is double. To drown such a boat without irreversible destruction, you need to try very hard, attaching all the Russian savvy.

An interesting feeling gives the suspension. On the move, the wheel, riding on the obstacle, keeps normal contact with it, and the vibration is extinguished.

Control by means of levers is unusual for the driver, but does not present difficulties and does without physical efforts. Experience comes quickly, drivers say that the all-terrain vehicle "Sherp" is able to waltz on a small area, if the owner will have such a desire.

Attracts attention to a successful device for ventilation and heating of the cabin. The air flow is organized in such a way that the cabin retains heat even with the windshield tilted away.

And one more important detail - "Sherp" is convenient for servicing. Access to power units is possible directly from the passenger compartment.

In general, in operation an all-terrain vehicle - this is solid dignity. The disadvantage of amateurs is the cost of both the machine itself and additional components. But what to do, for example, such wheels can not be cheap by definition, like the rest of the original components.
