Our research & development

For more than three decades, ABC Umformtechnik has stood for innovation, top quality and customer-specific solutions for wheel fastening systems and bolted joint solutions in the automotive industry. We see ourselves as a development partner for our customers and a pacesetter for the standards of today and tomorrow. An indispensable basis for this is our research and development.

The safety of our products is always a priority because it is a matter of connection points in the vehicle and thus the safety of life and limb. That’s why we have developed special test methods that ensure our products stay ahead of the competition.

Test method

We develop specific test methods and measurement technology to meet the requirements of our customers. In cooperation with our customers, innovative system solutions, surface systems as well as test methods and often new ways are developed, which even exceed the set requirements. Sometimes new test methods are developed, which allow to detect failures at a very early stage of development and thus to avoid them.

Bolting test rigs at room temperature
Friction coefficients are determined with the aid of measured torques, preload force and known geometric variables of the fastener. Multiple assembly cycles are performed to simulate the frequent change of wheels in European regions for wheel bolts.

Test rigs for determining coefficients of friction under high temperature loads
Temperature properties of surface systems as well as ABC CORROLUBE® surfaces are analyzed.

ABC wheel bolt test rigs
Assembly procedures on original components are simulated and simultaneous preload force measurement is performed on all wheel bolts. To simulate the frequent change of wheels in European regions for wheel bolts, multiple assembly cycles are performed.

ABC – BUP Bending Test Bench I / II: ABC Wheel Fit Test Benches
Analogous to complex driving tests at the customer’s site, the automatic loosening behavior of bolted connections is simulated. In addition, load data can be determined on the fasteners that occur under extreme cornering. For this purpose, we use our own strain gauge bolts, the ABC Multi Sensor Bolts.

ABC Multi Sensor Bolts
With the aid of complex strain gauge measurement technology and our own evaluation software, we carry out a detailed load analysis on the fastener in the original composite. This new method makes it possible for the first time to measure nominal bending stresses at the respective failure point of the fastener.
