Servo-hydraulic steering test rig

Full title:

since 2002

Contributors:

• Basic research on the pairing rack / pinion to assess the load capacity and types of damage of automotive steering gears

• Experimental investigation of fatigue strength (S-N-curves) and wear behaviour

• Experimental investigation of structural integrity during various overload conditions

• Utilisation of a servo-hydraulic 3-axis test rig to apply static or dynamic loads on steering gears or complete servo steering systems

• Application of a torque on the input shaft of the steering pinion which acts against resistance forces on the track rods
• Simulation of various driving conditions and examination of their impact on the system‘s components

• The main goal is to detect weaknesses in systems before the start of production and to guarantee the quality of steering systems during production.
