All the gears were shifted through for each gear stick to evaluate, amongst other things, the actuating force and the associated displacement. The minimum and maximum forces that occur when selecting the individual drive positions are precisely stipulated by the end customer Opel and must be the same for all the selector positions.
An identification label is only printed and attached for a gear stick that has tested ok. This label can be used to retrace the unique test file at any time. Gear sticks that are not ok are rejected. Each gear stick is thoroughly tested because there is a 100 % component test requirement.
The HBM solution:
An HBM measurement chain was designed comprising S2/100 N force transducers for tensile and compressive forces, WA/100mm-L displacement transducers, and the MP85ADP process monitoring system.
