    Test device and test bench with such a test device
    The invention relates to a test apparatus for a test stand for motor vehicles. Furthermore, the invention relates to a test stand with such a test device.
    With a test stand of the type mentioned tests on motor vehicles can be performed so as to draw conclusions about the vehicle behavior, the average consumption, the suspension setting, the brake system and / or the drive train of the motor vehicle. For this purpose, the test rig simulates loads on the motor vehicle to be tested, which correspond to the loads occurring in real ferry operation. As a result, time-consuming and costly real road tests can be reduced. Another advantage of a test bench is that the loads can be exactly reproduced.
    Conventional test stands comprise one or more test devices in the form of so-called dynamometers, which may also be referred to as load devices. Such a load device has a shaft which is connected to a hub of a motor vehicle to be tested. To carry out the driving tests, the load devices then apply a drive torque and / or a load moment via the shaft to the hub.
    To couple the hubs with the test devices, it is known to drive the vehicles on a mobile pedestal in the test bench and bring in a test position in which the hubs can be connected to the waves. In this case, a direct connection of the waves with the hubs of the motor vehicle would be possible in principle. However, since the vehicle hubs have different hole patterns (4 or 5 holes), an adapter device is generally used for coupling the hub to the shaft of the load device. For this purpose, it is known, the adapter devices before the introduction of the motor vehicle in the test at the hub of the
    Motor vehicle to mount. The adapter devices are supported by blocks on the mobile pedestal, so that the motor vehicle can be fully assembled and prepared in the mobile pedestal, before it is driven into the test bench.
    Such an adapter device is known from DE 20 2010 006 682 U1. The adapter device is used for coupling a commercial vehicle to a test stand, wherein the adapter device between a hub, a drive shaft of the utility vehicle and a test bench belonging to a load device of the test bench leading compound shaft can be used to couple the hub and the connecting shaft with each other. On the adapter device, a rolling device is provided, on which the adapter device can be supported in a state in which the adapter device is connected to the hub of the truck in order to enable a movement or procedure of the commercial vehicle together with the adapter device on the ground. The adapter device and the rolling device are mounted outside of the test bench on the utility vehicle and then the commercial vehicle including the adapter device is driven by means of the rolling device in the test bench and coupled to the connecting shaft. Thereafter, the rolling device is removed from the adapter device when the adapter device is installed together with the commercial vehicle in the test bench in the intended manner. The disadvantage here is that the mounting of the adapter devices on the commercial vehicle and the subsequent coupling of the adapter devices with the waves of the load devices are extremely time consuming and costly. Consequently, the productivity of such a test rig is limited due to the long set-up times. In addition, the long set-up times result in high operating costs.
    Furthermore, DE 10 2004 023 730 A1 discloses a vehicle test bench which can be used at the end of the assembly line by automobile manufacturers, i. The test stand has four movable support plates on each of which an electric motor for applying a rotary load to the hub of a motor vehicle is arranged For this purpose, the motor vehicle is moved by means of a commercially available vehicle hoist or a crane or a carrying and transport device already present on the production line into a desired test and setting position and arrested there Positionable vehicle mounts which can be adapted to the respective vehicle lanes to the respective wheelbase, which are manually adjustable and lockable or can be hydraulically positioned or regulated accordingly support the stub axles so that the unsprung masses, in particular the wheel / tire / brake components, are kept under test and adjustment conditions. However, it has been found that the coupling of the already arranged on the vehicle mount adapter devices with the hubs of the motor vehicle is very time-consuming, since the adapter devices must always be set anew on the conditions of the motor vehicle to be tested.
    However, especially with regard to the future RDE (Real Driving Emissions) legislation, according to which exhaust gas pollutants are to be measured not only on the test bench but also on real road trips, it is to be expected that the vehicles will only remain in the test bench for a short time.
    It is an object of the invention to provide a test apparatus and a test bench which have increased productivity and reduced operating costs due to reduced set-up times.
    This object is achieved with a test device having the features of claim 1, a test bench having the features of claim 17 and a test bench having the features of claim 18.

    FIG. 4 shows a second embodiment of a testing device 12, which differs from the first embodiment by the configuration of the supporting device 20. The support device 20 shown in FIG. 4 also has a support structure 78 comprising a support 80 and a bearing device 82. The carrier 80 is connected to the base 22, preferably screwed, wherein at its free end 84, the bearing device 82 is supported. The bearing device 82 is supported by a support plate 120 and two parallel, longitudinally extending bearings 122 on the support plate 86 from. The bearings 122 are preferably formed as elastomeric bearings. The bearing device 82 comprises two mutually spaced support plates 124 for receiving the adapter device 18, in particular the flange 58, and a base plate 126, on which the two support plates 124 are arranged.

The base plate 126 is arranged on the support plate 120, wherein the base plate 126 has ball bushings 130 which rest movably on the support plate 121. About the ball bushings 130, the adapter device 18 can be pivoted relative to support plate 120 and / or moved, wherein on the support plate 120 end stops 131 are arranged, which limit the movement of the adapter device 18. The end stops 131 are preferably designed as rubber stops. More preferably, the platen 120 is formed as a hardened plate. On the support plates 124, the flange 58 is supported, wherein the flange 58 is connected via pivot joints 132 pivotally connected to the support plates 124 in order to adapt the adapter device 18 to the fall of the motor vehicle.
    The test apparatus 12 and the test stand 10 are characterized by the support device 20, which supports the adapter device 18 in a test position and at a predetermined distance from the load device 16 on the movable base 22. This eliminates a time-consuming pre-assembly of the adapter device 18 to a hub of a motor vehicle and a time-consuming setting and coupling the adapter devices 18 to the shaft 26 of the test apparatus 12. To test a motor vehicle this must be brought into the test position and coupled to the adapter device 18. For this purpose, only the test device 12 must be adapted to the track width of the motor vehicle. Since the load device 16 is moved synchronously together with the adapter device 18, the track width can be easily adjusted by only the base 22 is moved.
