Dura Automotive Systems Reiche is using measurement technology from HBM to ensure that the steering coupling it produces meets the high production and quality control standards required.

The steering column is used in the latest Mercedes-Benz SLS AMG sports car, which has a peak performance of 420kW and a 6.3-litre engine that accelerates it from 0kph to 100kph in just 3.8 seconds.

This places high demands on the steering coupling, which connects the steering wheel and the steering gear.

It comprises a corrugated tube, a smooth tube and a double universal joint.

The latter – a so-called constant velocity joint – has a decisive influence on steering precision.

The coupling is manually assembled by Dura at its specially designed factory.

To ensure the responsive steering required for the Mercedes Benz SLS AMG, all components of the steering column are checked using HBM’s equipment.

Complete traceability of every working step is ensured with the HBM hardware and software used because each steering coupling that leaves assembly has a serial number.

The bending torque in the joint connecting both tubes of the steering coupling is checked using HBM’s PW4M platform loadcell.

This is also used to measure movement in both directions on a test bench.

Once the joint has been checked, the tubes are fitted with threaded inserts.

The force and displacement during the press-fit process is carefully monitored using HBM’s MP85A Fastpress process monitoring system.

All measured data are directly evaluated in the process controller, which ensures that press forces lie within the specified tolerance window.

The process controller both delivers an ‘OK’ signal and transmits the measured process data simultaneously to the test-bench control computer via the network.

Finally, the torque on any screws is measured and recorded during the tightening of screw fittings on the parts.

All process parameters are recorded and maintained in a database.

HBM UK Ltd

Our extensive range covers everything from strain gages via measuring transducers to analog and digital amplifiers. Since our amplifiers can be connected to a PC, measured values can be further processed and then meaningfully displayed with the aid of operator-friendly analysis software specifically designed for measurement technology.
