Testing complete vehicles comes closest to the conditions on the road and offers the advantage of being able to test a wide range of situations and processes in-house. Complex international test runs can thus be simulated in advance.<\/p>\n

At the heart of such a testing system are the four dynos, each of which is connected to one of the vehicle\u2019s wheel hubs. Thus, all drive train components are tested in interaction with the suspension and vehicle software. In contrast to exclusive\u00a0powertrain test beds, our vehicle test beds are equipped with a so-called cardan bearing, which hold the vehicle load.<\/p>\n

To facilitate installation, the cardan bearing can be moved in the horizontal plane and also turn in two axial directions.<\/p>\n<\/div>\n<\/div>\n

The cardan bearing is continuously fixed with the aid of pneumatic clamping elements, and the resulting angular offset in the shaft train is compensated for by means of a constant velocity cardan shaft.<\/p>\n

Furthermore, pre-tensioned damping elements on the Cardan casing ensure vibration-reduced operation. In recent years, ERNST has specialized in customer-specific solutions in this area and, as a system supplier, is able to manufacture the complete mechanics of such systems. This includes the design as well as the entire mechanical processing up to the in-house installation.<\/p>\n

The design varies according to the desired dimensions as well as the dynos used and the required performance data. As a rule, both the track width and the wheelbase can be continuously adjusted here.<\/p>\n
