There is no need to reinvent the wheel. Rethinking today’s technologies helps to cope with the future!
By entering the field of test stand construction for drive shafts, we have set ourselves the goal of further developing existing test stand technologies and breaking new ground. This is made possible by the combination of many years of experience and impartiality of new highly qualified employees. With the 2-Square, for example, we have developed a test stand that pushes the limits of what is technically feasible.
This test rig is used for lifetime testing of CV-Joint shafts and propshafts of the automotive industry. For this purpose the test rig enables the simulation of realistic loading and test shaft positioning and articulation as occur in real operation. The essential components of the loading circuit are two reversing gearboxes with ratios 1:1 and a center unit for the simulation of suspension travel. The 4-Square can be electrical or hydraulically driven.
This unique test rig is used for life time testing of propshafts and CV-joint shafts. For this purpose the rig enables the simulation of realistic loading and test shaft positioning and articulation as occur in real operation of drive shafts. These tests can be performed under extreme torque and speed parameters.
Modular Test Rig for lifetime testing and strength testing under multiple conditions.
Impact Test // Snap Start // Double Fatigue // Quasi Static // Rotational Fatigue
Driveline Testing // Power Unit Testing // Gear Box Testing // Clutch Testing // Differential Gear Testing // …
This test rig is used for lifetime testing of eight CV-Joint boots (4 shafts) under extreme high or low temperatures (-40°C to +150°C). Both joints can be articulated in a range from -5° up to 55°, the rotational speed can be set from +3.000 rpm to -3.000 rpm. Integrated grease detection with individual shut off.
Final conclusion: The cooperation with the company aixACCT mechatronics is always fair and competent. All promises were fulfilled and successfully realized. Our division owns four test rigs and even for the other three test rigs we received valuable and competent recommendations and support, when VW asked for advise.
With aixACCT mechatronics we have found a competent partner in the development of our new coating technology. Implementation and support is always done from the customer's point of view. Particularly noteworthy are the response times to inquiries and support.

Based on the experience of the large heavy duty 2 SQ test rig with its unique specification we developed driven by customer request a smaller 2 SQ dyno but with higher speed. Like in all other test rigs we implement new features and optimize the handling. Thus we developed an automatic alignment for an easy adjustment of the prop shafts.
