Accurate testing for reproducible quality
Püttlingen, July 2016 – To ensure the high level of safety and comfort in vehicles, several measuring, aligning and testing processes must be carried out in the end-of-line area. For this purpose, Dürr Assembly Products provides a complete package consisting of testing facilities for wheel geometry measurement, headlamp setting, the setting of driver assistance systems and Roll/Brake/ABS tests.
For wheel alignment measurement and setting with maximum precision, the x-wheel alignment stand is the perfect match. From the basic x-wheel mainline model through to complex systems with fully or semi-automatic setting, Dürr Assembly Products has the ideal solution for customer-specific requirements. The x-wheel d test stand, which is a further addition to the portfolio, is used for wheel geometry measurement in rework areas and special vehicle production.
The two non-contact measuring systems, x-contour and x-3Dprofile (with three-dimensional measuring technology), offer accuracy and reproducibility. In conjunction with the x-tronic balancer for steering wheels, Dürr Assembly Products ensures precise wheel alignment with horizontal steering wheel position when driving in a straight line.
Ready to meet current and future demands
New headlamp models as well as different legal guidelines require the use of sophisticated setting and testing technology. The x-light headlamp setting system ensures accurate testing and enables the fully or semi-automatic setting of the main headlamps, fog lamps and high beam headlamps. In conjunction with the x-wheel geometry test stand, the headlamps are set by taking into account the wheel geometry data. Thanks to its modular design and great flexibility, the setting station ensures that even future requirements can be met without any problems.
Due to the increasing use of driver assistance systems in vehicles, image processing in connection with headlamp setting systems is becoming more and more important. Driver assistance systems based on infrared distance sensors as well as radar systems with auxiliary mirrors can also be set and checked using x-light. (Please take a look at the related article on the setting stations for driver assistance systems, x-DASalign.)
The x-road Roll/Brake/ABS test stand can be used to simulate different driving situations such as accelerating, braking or hill starts. In addition, control devices for front-wheel, rear-wheel and 4-wheel-drive vehicles in the end of line area can be parametrized and checked. The x-road essentially consists of four roller sets, one for each vehicle wheel. Each roller set is linked to a vector controlled AC motor. The motors are controlled by frequency converters and work individually in a driven or generator mode. Any surplus energy is returned to the grid.
Automated test sequences ensure reproducible test results. Freely definable test sequences add to the flexibility of the concept. The x-road combines highly available system technology and accurate measuring technology. Prior to delivery, the quality of the measuring system is carefully checked using the x-cal test device, which has been specially developed for this purpose.
