Roll Test Stand
Our computer controlled vehicle test systems are normally arranged to provide a total test package at the end of the vehicle production line or to meet the need for a stand-alone test station, for example in development, quality audit, or post rectification tests.
The test stand can be configured for different kinds of tests, such as – function, brake, ABS, EDS, ESP, ASR, AWD, etc. – for car, commercial vehicle, tractor or motorcycle testing. It is possible to have all this testing capability in a single test machine.
The rollers of the test machine are designed with an inertia appropriate to the vehicle mass. This ensures the vehicle on test accelerates and decelerates close to normal road running conditions.
Main Features:
- Function, brakes, ABS, ESP, EDS, MSR/ASR tests
- Vehicle-specific functional tests by the simulation of individual driving curves
- Test of vehicles with different wheel bases and tracks on the same test stand
- Minimal cycle time through 4-motor direct-drive-concept
- Recovery of energy into network
- High reliability
We offer different kinds of rolling road test stands, single roller machines and also twin roller machines. Both these machines are available with the NEW! drive technology and frequency controlled asynchronous drive motors at each roller.
