Translation of "Rollenprüfstände" in English

For stationary vehicle testing, roller test stands are predominantly used as stationary test stands.

Two roller- and five engine-dynamometers are available.

For surface inspection, but also for classic chassis or roller test stands, everything is automated by us.

Tappets 49, 50 are often used in cases other than chassis dynamometers where a lowering of the skid 1 is not required because the measurement and test instruments can be moved through opening 31 and can be applied directly to the contact surfaces of the vehicle wheels. In these applications, the conveyor devices need not be lowered.

For example, in order to exactly determine the exhaust gas properties of a vehicle determined on such test stands, the automobile industry and the environmental agencies place high demands on the measuring accuracy of such roller test stands.

In the United States, the Environmental Protection Agency has established vehicle standards which require highly sophisticated chassis roll dynamometers for road simulation in the testing of vehicles.

With its Test Centre the Company possesses highly dynamic state of the art engine (fig.1), component (fig. 2) and roller test benches (fig.

Dynamometers are a great way to measure performance, providing true ventilation and the staff knows how to use the technology.

The dynos produced by us can work in all of these configurations - it depends only on their option and accessories.

Even though DE 195 05 415 A1 describes an exhaust gas test stand wherein two roller-type test stands are connected to a single CVS system, DE 195 05 415 A1 merely provides switching over the exhaust gas inlet, thus making it impossible to use one branch for diesel engines and one branch for Otto engines because, particle and HC residues would then be expected in the area of the mixing zone.

It is known that chassis dynamometers make it possible to test motor vehicles, with the wheels of the motor vehicle to be tested resting on large rollers of a chassis dynamometer.

The method can of course also be used for roller dynamometers which are utilized for test vehicles having more or fewer than four wheels.

As mentioned above, the method is not restricted to the use on roller dynamometers for four-wheeled test vehicles 2 .

This can take place either on special test rigs, such as roller dynamometers for example, or on test tracks (whether these are in the form of real roads or on a special testing ground is not important here).

Roller type test stands known in the art may be used to simulate the behavior of a vehicle, taking into account friction and air resistance.

Test benches for driving simulation are known in the art in several variants (e.g. roller test benches, conveyor belts).

In addition, the legal expert refers to the possibilities of the police, such as roller dynamometers to determine maximum speeds as well as the option to seize vehicles in the event of doubt and to have them inspected by an expert.

The Canadian wind tunnel experts of AIOLOS Engineering Corporation contributed the wind tunnel technology, the wind tunnel control unit, the dynamometers and the solar simulator.

Moreover, the dynos are calibrated with the use of a gravitational standard of the torque, which assures the appropriate readings of absolute measured values.

Additionally, it is able to engineer and supply components for many engines as well as providing engine dynocell and rolling road facilities for adjusting management systems and carburettors.

Dynos working at the inertial mode, and not equipped with the brake, will be named further inertial dynos.

All of the manufactured dynamometers are CE labelled, which means that they are manufactured according to the applicable European standards.

This laboratory is equipped with three roller test benches and a sophisticated measuring system used to analyze conventional emissions, mass and number of particulate matter particles emitted by diesel and GDI engines, as required by Euro6 regulations.
