The alignment of the wheels, sometimes referred to as breakage or tracking, is part of the standard car maintenance that consists of adjusting the wheel angles so that they are parallel to each other and perpendicular to the ground. The purpose of these adjustments is to reduce tire wear and to ensure that the vehicle's travel is straight and true (without "pulling" to one side). Alignment angles may also be altered beyond the manufacturer's specifications to obtain a specific handling characteristic. Motor and off-road applications may require angles to fit well beyond "normal" for a variety of reasons.
There is more to the alignment of the wheels than to the indications that appear on a computer alignment machine. While today's most useful wheel alignment systems facilitate and accelerate "factory" alignment, it is important to gain a basic understanding of the terms and geometry of wheel angles and the results of angle adjustment.
Types of Wheel Alignment
The "original" approach to measuring and diagnosing vehicle wheel alignment is called the center-line two-wheel alignment, which basically allowed you to measure and adjust the positions of the front wheels or steering axles. This method, now obsolete, does not take into account the positions of the rear wheels and is not effective, since it ignores the thrust direction of the rear axle.
The accepted approach currently considers the actual location and direction of the rear wheels (even if the rear wheel angles are not designed to be adjustable). This method allows you to include and measure the rear axle thrust line / thrust angle. As a result, this allows you to adjust the angles of the front wheel in relation to the rear wheel angles, regardless of the geometric center line. In the case of a vehicle that does not have adjustment of the rear wheel angles, this allows us to perform a "four-wheel drive Line "alignment.
If the specific vehicle at hand has an independent adjustment of the toe of the rear wheel, we can achieve optimum alignment of the wheels using the total approach of four-wheel alignment, consulting and adjusting the thrust angle of the vehicle as close Possible from scratch.
If the thrust angle of the rear axle of the vehicle is "zero", this can result in "dog tracking" (where the vehicle body is twisted / twisted in relation to the direction of travel of the vehicle), which In turn can contribute to the wear of the Left / Right tires. If the rear wheel angles are adjustable, this allows us to perform a "total four-wheel" alignment.
