DREAMS Driving Robot EAsy Movable <strong>System</strong> The Control Sistem driving robot DREAMS represents a new approach to the automatic vehicle driving for tests on chassis dyno. Thanks to an industrial (anthropomorphic) robot with six degrees of freedom, the management of the shifting gear level is done as a human arm. The system can be optionally equipped with a conditioning system to operate in climatic test cells down to -40 °C. MAIN FEATURES Quick installation: Less than 5 minutes | Single operator: trolley for Robot positioning Robot Actuator unit: Installation on driver/passenger seat (no modifications to the vehicle) Gears positions control: Automatic detection for any configuration Transmission types: Manual transmissions: any number of gears and positions | Automatic transmissions | Sequential transmission Engine start: Ignition key/button directly operated by the robot Driving Robot for Chassis Dyno 6 Software: User-friendly interface | Vehicle configuration and drive cycles definition Cycle driving: Very high repeatability of driving sequences | Different driving behaviour Data Managers: Tablet PC unit for vehicle configuration data and drive cycles AREA OF USAGE Exhaust emission tests on chassis dynamometers | Transmission and power train tests on chassis dynamometers or test cells | Mileage accumulation and durability tests | Climatic tests | Fuel economy tests | R & D studies
DYNOSAUR Chassis dyno for light and medium duty vehicles Control Sistem’s roller bench has been designed for use with light and medium duty vehicles. It is a single 48 inches roller type suitable for emissions measurement and performance tests. The Dynosaur is driven by an asynchronous electric motor controlled by a vector inverter, placed between the 2 rollers and mounted with an oscillating frame with a load cell torque reading. The motor’s supports contain a device for the slow rotation of the bearings in order to minimise hysteresis and wear of the bearings. TECHNICAL SPECIFICATIONS Roller diameter Internal distance between rollers Roller width External roller distance Maximum axle load Maximum motor power Maximum force on roller Simulated inertial mass Operating temperature Operating temperature (air-conditioned version) RoBeC Rotating Belt Chassis-dyno Why a rotating-belt instead of the traditional roll? Using a traditional roll system, the tyre runs on a curved surface that is far away from real conditions. Main effect of this, is an unnatural deformation of the tyre that reduces drastically its life. The RoBeC is aiming to give a flat runway to the tyre, similar to the road condition, in a very compact machine. This results is obtained using a “Rotating-Belt” where the runway is made of a commercial “Poly-V” belt. The belt is kept stretched by a tensor cylinder to generate a flat tyre belt contact surface. The electric motor and the belt are placed on a sliding frame, connected to the main frame by a load cell to directly read the traction force of the wheel.
