Machine function description & structure introduction
Tire endurance & high speed test machine can meet the China national standards and the requirement of European CE Mark.
Tire endurance & high speed test machine mainly consists of main machine, motor driven system, hydraulic loading system and control system.
Machine frame assembly is a high-stability steel frame, the supporting parts includes carriage assembly, drum shaft assembly, main motor, and main hydraulic cylinder etc. Left & right Positions and drum assembly form the machine as a whole piece, which is of high stiffness and rigidity, and which is of long-term service without deformation.

Hydraulic servo system is in closed-loop control. Servo valve controls loading cylinder. Loading cylinder moves carriage, which keeps the carriage moving along the linear guide rail to push the test tire mounted on the shaft end onto drum or take the tire away from the drum. Load value signal will be transmitted to main control cabinet through load cell mounted on carriage. The showing, adjustment, controlling and printing of load will be controlled by P.I.D.
System completes with PLC system and IPC system, which could acquire the data in many points and manage the two systems, and which features with easy operation interface, abundant data acquisition, accurate signal measuring, and simple operation steps. All the functions can be proceeded on the operation interfaces. And the all the interfaces such as “Automatic Test Interface”, “Manual Test Interface”, “Programming Interface”, “Program Selecting Interface”, “Alarm Interface” and “Config Interface” can switch between each other easily.
