Wheel alignment and adjustment

The VisiCon family of measurement probes (dPP, dPPTwin, VisiScan) are measurement sensors for the non-contact three-dimensional detection of surfaces. The probes record 40 images per second, from which a 3D model of the illuminated tire is generated. This can be used, for example, to calculate the chassis parameters toe and camber. The different models have particular strengths in different applications so that we can offer the perfect solution for every system.

With the illumination unit, the body height can be determined, measured at the position of the wheel house edge. It is connected directly to the dPP probe, which means that no further constructional measures are required. The design of the illumination unit allows the measurement of all types of vehicles.

According to DIN EN 62471, our illumination unit is classified as risk group 0 and is therefore completely harmless to the eyes, even if exposed to for a long time.

The wheel adjustment table as an independent functional unit consists of a roller set, a pusher for vehicle centering and the bracket for the dPP probe.

The roller sets consist of stainless steel rollers and integrated floating plates. The front roller is operated by an electric motor, while the floating plate is pneumatically moved into the positions “locked”, “floating” and “swiveling” .

Optionally wheel load scales and a device to measure the steering angle (±50°) can be integrated.

For wheel aligners, we use electric centralizers with pressure rollers (pushers). The vehicle wheels stand on rotating rollers, which are set in motion during the centering process. The pushers bring the vehicle into the correct position and are then retracted for force-free measurement.

Our software is perfectly adapted to the requirements of wheel alignment. The widely used measurement program VisiWheAl is the central software module for controlling the dPP 3D probes and calculating the wheel geometry. It also offers the possibility to provide different displays for the user in parallel on one or more monitors (directly on the plant computer, on traversing columns, in the pit etc.).

Our process software completely controls the process or enables control via a PLC by means of an integrated interface (VisiCon or customer).

Traversing wheel base units are an extension of the wheel adjustment table and allow flexible use of the wheel aligner for different types of vehicles. During adjustment, the measurement probes, floating plates and centering units of the rear axle are moved. The adjustment of the wheel base can also be done when a vehicle is already stationary.

The track width traversing unit used in wheel geometry analysis is an extension of the wheel adjustment table. It enables the measurement of vehicles with a large variance in track width. For this purpose, the measurement probes, floating plates and centering units of both axles are moved laterally.

The steering wheel gauge enables the measurement of the steering wheel angle directly at the steering wheel and – in combination with the additional steering angle measurement device – the determination of the ratio of the steering angle to the tire angle.

The optional extension for the chassis analysis enables a defined pulling down and lifting of the vehicle, which can also be load-controlled via optional wheel load scales. At the same time, toe and camber curves are recorded via the trim position.

Movable cover of the pit underneath the vehicle. The cover can be designed to be traversable on request.

The alignment of the system, especially the measurement probes, is carried out with a master gauge. For this purpose, four measurement plates are mounted on the frame. If required, additional setup components for DAS calibration systems or headlight adjustment can be attached.

A rolling master is used to check the repeat accuracy of the measurements (toe, camber, wheel center, wheel arch edge). If desired, the Rolling Master can also be used as an equipment carrier for reference headlights, ACC antenna, etc.
