Wheel alignment: Optimal axle geometry through the use of wheel aligners for cars, vans, trucks and buses
What are axis measurements done for?With the help of a wheel alignment and tracking the optimal alignment of the wheels on a motor vehicle is carried out. This helps to optimize fuel consumption as well as to safely move and maneuver the vehicle. In addition, the wear of the tires and other vehicle parts is thereby minimized.
On a tire tread, which is noticeably more worn on one side than on the other, one can recognize a wrong adjusted axle also as a layman. Due to a shifted axle adjustment, the tires are not evenly on the road surface, resulting in a greater resistance between the road and tires on one side of the vehicle and thus also to a higher tire wear.
By changing the axle geometry, however, the wheel bearing can also wear out or the braking distance can lengthen, which can represent a high safety risk. Therefore, it makes sense to carry out a wheel alignment at first signs. Signs of an axle adjustment include, for example, a steering wheel that is tilted, as well as changes in the maneuvering of the vehicle, especially in curves. Even unusual noises on the chassis during driving, such as rumbling or squeaking noises in curves can indicate a change in the geometry of the axles. In addition, an increased fuel consumption may indicate a misaligned axis.
A misaligned axle geometry can be caused by the wear of moving parts on the chassis or by high stress during driving, such as when driving through a pothole or the unfortunate driving on a curb, as well as in an accident or bump.
In addition, a wheel alignment should always be carried out following modifications or major repairs to the chassis.
Wheel aligners: modern helpers for wheel alignmentToday's computer-aided wheel alignment systems are used for wheel alignment, which use sensors or lasers to give precise information about the type of vehicle, whether the axis of a car, van, truck or bus is set correctly and where it needs to be improved.
Wheel aligners are available in different designs, for example as 3D wheel aligners or laser measuring devices.
In laser wheel alignment, sensors are mounted on the wheels of the vehicle to determine the exact position of the wheels and send the data to the wheel aligner. Based on the transmitted vehicle data compared to the manufacturer's data on the correct positioning of the wheels for the corresponding vehicle type, the computer then evaluates whether a correction must be made.
In 3D wheel alignment, in addition to attaching sensors and transmitting the corresponding position data, images from the vehicle are also transmitted to the wheel aligner using a camera. The images from the camera are converted by the 3D wheel aligner into a three-dimensional model, which the vehicle specialist can view and analyze on the screen of the wheel aligner. By aligning with the manufacturer data, weak points and misalignments of wheels and axle are quickly detected by the wheel aligner and can be remedied quickly with this method.
It is worth purchasing a 3D wheel aligner for workshops that carry out axle surveys quite often, as wheel alignment can be carried out faster and with maximum precision.
