Driving heavy vehicle with wheels and axles, which are not regulated and do not put up as desired, can lead to undesirable consequences. Centrifugal resistance car becomes much more - as a result of significantly increased fuel consumption and tire wear. Moreover, under high centrifugal resistance will be much faster to fail connecting joints, insulators, bushings and springs. Such problems and the constant "steer" evoke a strong driver fatigue, which often leads to accidents.
If the axes are not parallel, they make the car move in a circle. If in addition to this, they are installed out of alignment, the management of such a vehicle is very dangerous, because the car is much more acceptable place on the road and it always pulls to one side.
Here is an example of the results of tests conducted with a stationary train with fixed axes.
In the first test, when all the axes were displayed correctly, the combination consumed 30 liters per 100 kilometers. (Average fuel consumption of trains).
In the second test were set parallel to the axis and with a slope of 10 mm \ m Fuel consumption has increased to 32 liters per 100 km., Ie by 6.7%.
When the axis of the third test were installed with a slope of 10 mm \ m but not in parallel. Fuel consumption has increased to 35.6 liters per 100 kilometers. The striking increase in fuel consumption by 18.7%.
Example calculation:
The most common motor combination - two-axle tractor semi-trailer with triaxial. Average total distance traveled by car per year is 150,000 km.
Tires:
Most of the cars that drove 150,000 km, needs a new set of tires, costing about 4,000 euros. Experience shows that when properly regulated wheels and axles we can save about 20%, or 800 Euros.
Fuel:
The car, in which the axes are arranged in parallel and with a properly adjusted the angles of the wheels, consumes about 30 liters per 100 kilometers. That is, 150000km x 30 \ 100 = 45 000 liters a year.
The car, which has distorted axes, will spend at least 6% more fuel that is at least 2,700 gallons per year more, which is equivalent to 1700 Euros.
We saved a 1700 Euro. the cost of fuel and 800 Euro. the cost of the bus. These costs can not be compared with the cost of installation and adjustment of the car with
ford f250 leveling kit.
Modern transportation - high-tech product with high productivity for rational use. All this requires proper adjustment of the chassis of the vehicle. Time necessary to produce control the alignment angle, longitudinal and lateral angles of pins, parallel and skewed axes of the vehicle.
