Effect of the gauge and other parameters on vehicle behaviour
Determines the optimal value of the above parameters and their required ratio of engineers-developers involved in car creation. According to the results of their calculations, the car is able to manoeuvre with the minimum capacity and wear of the tires, while showing excellent stability, which is the guarantee of safe movement.
The wheel, the ground clearance and the wheelbase of the car are the main parameters. They depend on them for stability, manageability, easing, mobility and braking performance. For front and rear axles, the gauge length may vary, so separate lines are provided for the vehicle characteristics.
Definitions of basic vehicle parameters
The ground clearance is the distance from the road to the edge of the lowest component of the vehicle structure. The vehicle is dependent on this indicator.
Wheelbase, this is the distance measured between the front and rear wheel centres.
Colea is the distance between the median lines of the left wheel tracks on one of the axles of the car. When the axle is equipped with two wheels (trucks, buses), the track means the distance between the middle of the left and right pair of military wheels.
The size of the gauge has a direct effect on the behaviour of the vehicle when cornering and transverse of the body.
The movement of the car, with the different values of the front and back tracks on the road, will be hampered by the fact that the wheels of the rear axle should be laying a new track for themselves.
Strict limitations on key parameters
When comparing a gauge with a wheelbase, the gauge cannot be greater than a certain value. Thus, the ratio of gauge to wheelbase (base/track) is within 1, 7-1.8 and cannot be less than 1.6 for almost all vehicles.
The higher the ratio of the baza/gauge, the car is more stable at high speeds and, it has become, it is more comfortable.
If there are various front and rear wheel tracks on the vehicle, it has to be used as mentioned above for the rear axle wheels on sand, loose soil or snow. This in turn requires a more powerful engine and, as a consequence, additional energy costs. In addition, there is a decrease in the propellant, the fuel consumption increases due to increased resistance to the car.
The car's wheel is defined by the manufacturer's design, and the main parts and components of the suspension are calculated for this size. When the car is carried out on its own, it often tries to carry the wheels a little beyond the wheel arches, thereby increasing the wheel tracks.
This in turn increases the load on the vehicle suspension, changing its characteristics. This increases the load on braking and the staff braking system will no longer be able to effectively brake the vehicle. For this reason, in addition to the increase in the gauge, a more powerful braking system must be installed. Among other things, the expansion of the track will also have an impact on the life of the bearings of the steps, significantly reducing their resources.
In the auto-port, when preparing a serial car, it usually increases the wheel track without installing the prowls or discs, but will remove the beam, cut it, and insert a new part and digest it. A mandatory condition in such cases is the use of the same material as the beam material.
A car with a large base more stable on the track even under adverse road conditions (a bright gauge or slippery surface). The basic car is indifferent to the small unevenness of the road, but when large sakes are passed, the risk of hitting them with the silencer or silencer, or stuck in the snow or mud, is increasing.
The wider the track, the safer and more stable the car is in sharp turns and maneuvering. However, if the car is wide but short, if the vehicle is hit by a frozen section or a clay or snowed shoulder, it can simply fly off the road. For example, a "Niwa" car with full power off. Therefore, the choice of the ratio between the parameters of the base and the track that determine the characteristics of the car is very important. This is, of course, not the only factors influencing the behaviour of the car and its controllability-the building of the car (the location of the engine), its transmission, the distribution of weight in the axes, etc.
Bas/gauge selection theory
In the first review, the ratio between the base and the track is set by the car class (comfort level in the cabin), the limousines are long and their width is set by the standards of the road. But it's not like that.
The increase in the surface of the wheels of the wheels is associated with sufficiently rigid tolerances for the ratio of the track to the base. For example, the compact car Ford Ka has the same ratio as the Audi A6 (by the way more than Audi A4). It is clear that some of the preferences dictate a class of cars: when moving along the road for comfort, it is more important than its direct stability, no one is laying out the cool virages on the limousines.
Some conclusions may be made. The more the ratio of the beza/gauge, the car is more comfortable. The largest numbers have such marks as BMW or Mercedes, and low-cost small-liers have a ratio less than at least 0.1.
It is worth noting that the large difference in the width of the front and back track cannot be made on conventional machines, which is related to different strains directly affecting manageability. Thus, in the compartment of sports, there are usually two people and can carry a road bag in the trunk, which will not have any impact on the development. When the family estate was being considered, it was difficult to take into account the changing position of the centre of gravity.
What you need to know about the rustle of the vehicle
A separate choice of tyres that deviate from the factory default values can have negative consequences. In this case, the ratio of the base/track and the car will be inclined to skid and increase the wear of the suspension parts.
The widespread use of "Russian packages" by producers is not quite clear, for our roads, which increase the number of clicks against the base. It is known that any change results in a configuration failure, including a change in the ratio of the beach/gauge
If you choose a car, one of the arguments can be a base/track relationship, if it is smaller, the car for the city, not for the track. When travel on the road is expected, a relatively narrow track is chosen-a larger ratio of the beza/gauge.
