The correct alignment

To understand the importance of a correct wheel alignment, we can try with a little experiment: wear two different shoes, swap the right with the left and then walk with a height difference of, say, ten centimetres between one leg and the other. At best, this will result is an uncomfortable, awkward and slow walk. In addition, there is also the serious risk of falling and, in the long run, of having physical repercussions due to incorrect posture. That is what wheel alignment is for: adjusting the vehicle's “posture”. Technically this is a procedure to be carried out strictly in a workshop if one wishes to have the correct geometric angles on all the wheels. The main ones are toe-in - a term that is often mistakenly understood as a synonym for alignment -, camber and caster. These three values have the power to influence the way both tires and suspensions behave. The correct alignment guarantees the best footprint, resistance to stress, driving precision, stability, handling, as well as better efficiency in terms of tire wear and fuel consumption. Toe-in is the angle formed by the wheel in relation to the longitudinal axis of the vehicle on the horizontal plane of the direction of travel. Positive toe, or toe in, is the front of the wheel pointing towards the centreline of the vehicle. Conversely, toe-out, or negative toe, is when the front of the wheels tilt outwards from a vehicle’s centreline. Finally, toe-in is neutral when the two opposite wheels are perfectly parallel to each other. A positive toe-in usually enhances stability, while a more negative toe-in favours vehicle responsiveness. A correct toe-in is the one that respects the manufacturer's specifications: the penalty is an overall downgrading of tire and suspension performance. The effects of incorrect toe-in can be easily detected by the driver who feels that the vehicle is "pulling" to one side and that the steering is rather stiff or misaligned. Poor toe-in can also cause abnormal tire wear and increase fuel consumption. The concepts of camber and caster, on the other hand, are much less well known. The first defines the angle between the vertical axis of a wheel and the vertical axis of the vehicle when viewed from the front or rear. If the top of the wheel is farther out than the bottom (that is, away from the axle), it is called positive camber; if the bottom of the wheel is farther out than the top, it is called negative camber. The camber is a value that affects both the vehicle's grip when cornering, as it increases or decreases the footprint of the tread on the ground, and how quickly the tire will wear. Also in this case, the best camber is not necessarily the one where the wheels are perfectly perpendicular to the ground because elements such as, for example, load transfers while driving, which can weigh heavily on the wheels and suspension, must be taken into account. Furthermore, a negative camber at the rear increases grip and facilitates cornering. Finally, Caster defines the angle that identifies the forward or backward slope of a line that is drawn through the upper and lower steering pivot points. If the line slopes towards the rear of the vehicle, then you have positive caster. If the line slopes towards the front of the vehicle, then the caster is negative. A slightly negative angle improves manoeuvrability but decreases straight-line stability as speed increases. On the contrary, the latter increases with a more positive caster angle. On the market there are several technologically advanced tools that help the aftermarket specialist to produce, easily and quickly, the correct wheel alignment for any type of vehicle.




Q.Lign wheel alignment, the latest addition to the Beissbarth family, besides the qualities that have always distinguished the German company’s equipment, introduces new features: new graphic interface, wireless connectivity thanks to which alignment can be carried out from any device, new set of patented Q.Grip wheel clamps designed to speed up operations. Once in place the system immediately provides the measurement values, helping the operator to identify any anomalies on the vehicle, even before investing time in selecting the program. Targets are automatically detected by the system and do not have to follow a specific installation sequence. Being self-centring on the shoulder of the tire, the wheel holders allow working on all types of wheels without having to touch the rim thanks to three-arm wheel clamps and 4 auto-identification targets. Another innovative element is the high-precision measuring sensor. Q.Lign requires no cabinet or support poles and is therefore completely portable. In addition, connecting Q.Lign to the local network allows to operate from any device on the shop floor. The new interface software has been renewed in its graphics and browsing menus. Q.Lign is finally "ADAS ready". The software and the tools such as sensors, targets and clamps in addition to the classic alignment functions give the possibility to work on the calibration of electronic sensors without repeating the preparatory work and without leaving the alignment program.



Speed, precision, ease of use and reliability characterize all CEMB wheel alignment solutions. The range, distributed in Italy by Sipav, offers CCD, 3D or contactless systems. Among these, the Argos contactless wheel alignment system stands out, which ensures the measurement of camber and toe-in in less than five seconds. Argos is the result of an extremely advanced technology developed entirely in-house. The procedure guarantees surprising ease of use thanks to the automatic start of the measurement process without any manual input from the operator. The newly introduced license plate reading function quickly recognizes the vehicle and automatically selects all the necessary specifications, for an immediate start of the measuring process. Without any clamps, detectors or targets, the Argos allows you to check all vehicles entering the workshop, generating a clear report of their status, increasing workshop productivity and customer satisfaction. In addition to comprehensive vehicle alignment results, Argos also provides an easy-to-understand Audit report, which contains a list of out-of-specification angles and related problems that may reflect on driving. The Audit printout helps the operator to present a clear overview of the vehicle's condition to the customer and the customer to make more informed decisions.



R.E.M.O. (Robotic Equipment for Measuring by Optics) by Corghi (Nexion Group) provides workshops with all the opportunities offered by innovative contactless technology for wheel alignment: pre-control and adjustments are carried out very quickly and without the need of clamps, passive targets or other devices. The accuracy of the measurements is of the highest level thanks to high resolution Hi-Q infrared cameras for artificial vision.

The steps involved in measuring and adjusting the angles are simple and take place automatically. R.E.M.O. is available in two versions: 4C and Compact Due, i.e. with four or two robotic units. The choice depends on the specific needs of the workshop. In case of high working volumes, the 4C version is recommended due to the exceptional speed of the system.

While at work, the robotic units automatically position themselves in front of the wheels. This is essential to guarantee optimum performance regardless of the vehicle's wheelbase. In addition, the optical scanners automatically move on vertical rails to be able to "follow the vehicle" at any lift extension. Each unit is independent and projects a laser light onto the wheel. Using the two stereoscopic cameras, it determines its angles and recognizes its location in space through a reference system created with the two targets positioned in front of the lift. The identification of the vehicle upon entering the workshop is easily carried out by scanning a specific QR code, issued to the customer when the vehicle is delivered. In the central unit, in addition to the image acquisition system, there are PC, monitor and an A4 printer to produce a pre-check and inspection document.

John Bean

John Bean (Snap-on) affirms its technological supremacy, presenting a new series of V2380 wheel aligners, a fast, precise and intuitive solution created to simplify work. Among the strengths of the new John Bean V2380 set-up is its small working platform: the 1.7 m between the cameras and the turntables represents one of the smallest footprints in the 3D wheel alignment segment. Thanks to an advanced camera system, the John Bean V2380 automatically follows the movements of the lift. The cameras follow the height of the vehicle, so there is no need for adjustments every time the lift is moved. Alignment readings are also ready in less than two minutes. Tread width and wheelbase values, collision damage, rolling radius measurement and discrepancies as well as tire size discrepancies are quickly detected. Thus, the interactive software promotes fast and intuitive adjustments. Through the interface, in a few simple steps, the operator can check if the measurement is correct or if there are problems and discrepancies that need to be corrected. Finally, the new John Bean can connect via WIFI network to mobile devices, receive automatic software updates (provided in the various John Bean subscription plans), share data and information, send and print reports.



Digital ADAS from Mahle sets new standards. Thanks to the digital Targetless system, the Connex Digital ADAS calibration tool no longer requires physical targets. Instead, it calls up the correct reference images for test management on its 4K Full HD monitor by simply selecting the make and model of the car being serviced. The Keystone technology (patented by Mahle) allows the system to adjust the digital image of the monitor starting from the positioning of the vehicle to provide a perfect match between the ADAS sensor (camera/radar) and the instrument without having to perform long manoeuvrers. This allows a perfect and immediate calibration, without wasting time or having to reserve special spaces in the workshop for service. The Digital ADAS station is also fully automated and can be used even by a single operator. In addition, although it is possible to calibrate starting from the rear axle, the Mahle Digital ADAS procedure measures from the front axle by default for better performance in terms of calibration accuracy and speed of operation. Finally, Mahle Aftermarket is launching on the market a certification of the calibration result - the Digital ADAS Certified Calibration (DAC2) system - as part of a project involving the entire supply chain (manufacturer, distributor, installer, etc.).


M&B Engineering

M&B Engineering offers a variety of solutions for measuring wheel alignment with CCD detectors or with 3D targets. At the top of the range, we find the Sniper WA 100, a 3D system, equipped with a mobile cabinet able to produce the measurements of wheelbase, track, diagonals, wheel diameter, friction and so on. Sniper WA 100 also allows for single-wheel run-out measurement, useful when space is scarce. The HD cameras are automatically adjustable to the height of the lift, thus reducing measuring time. Universal self-centring wheel clamps allow operation on wheels from 12" to 24", but three-point rim clamps and three-point tire clamps are also available as options. Designed for workshops with limited space, the Sniper WA90 is, on the other hand, a 3D alignment that, although compact in size, guarantees all the essential functions and is therefore suitable for those who are just beginning to practice wheel alignment. The M&B range in the wheel alignment segment is completed by the CCD Sniper WA80, Sniper WA80 Truck and Sniper WA85 wheel aligners. All wheel aligners in the M&B range are easy to use thanks to specially developed software that supports the operator during all phases of the procedure as well as selling the service to potential customers. The software is equipped with an "Audit" function that provides a detailed and easy-to-understand report of possible disturbances perceived when driving.
