Kinematics testing bay
The examinations that can be carried out with this test bench are not standard tests in a production line, but also offer the customers the possibility to test new axle series under limit loads in laboratory conditions. The tests are carried out quasi statically. To this end, the commercial vehicle is attached to the rigid platform body using a load gantry. Then forces and paths can be transferred to the braked wheels. These are generated in a vertical direction by hydraulic cylinders.
The Active Roll and Sliding Plates (ARUS plates) mounted to them can apply hydraulic forces and/or paths in a transverse and longitudinal direction. Also, torques and/or angles can be transferred into the chassis around the vertical high axles.
The steering is set to straight ahead. The force flow of the ARUS onto the axles is realised by means of friction between the wheels and the wheel contact surface.
All driven axles can be moved in a path and angle-controlled and also force and torque-controlled manner, and the control mode can be switched jolt-free at any time. The path sensors for the two horizontal axles and the angle sensor for the high axle (6-component load cell by FGB with calibration device) were integrated directly into the ARUS plates. All measuring variables that are important for assessing the dynamic road behaviour are recorded and assessed during the simulation. This allows the customer to analyse the driving behaviour in various load scenarios and take corresponding optimisation measures.
