i.About The Product The device is designed based on the Toyota lexus LS400 air suspension system to holistically demonstrate the structure and operation of air suspension. The device applies to theoretical teaching and maintenance training of the air suspension system in secondary and senior vocational skill schools, normal education and training institutions. ii.Features 1.A real and operable air suspension system is used to illustrate the structure of the system. 2.The height of air suspension and hardness of shock absorber are adjusted by operating the height controller or adjusting the suspension height or actuators, for example, the ECU compressor, height control solenoid valve, and shock absorber hardness controller. In this way, the device demonstrates operation of the air suspension system. 3.The training bench is made of advanced aluminum-plastic plate with characteristics of not less than 4mm thick, corrosion resistance, impact resistance, pollution resistance, fireproof, and moistureproof. Its surface are processed by special craft and spraying primer. Never fade color circuit diagram and working principal diagram are painted on the board whose surface coating with varnish. The trainees can learn and analyze the working principle of the control system by referencing the diagram and the real object. 4.The training bench is installed with detection terminals to detect electric signals, for example, resistance, voltage, current, and frequency, of circuit components of the air suspension system. 5.The training bench is installed with a fault indicator lamp and a diagnosis socket, which automatically diagnoses the system by blinking fault codes in case of short circuit. 6.The training bench’s base frame is made in steel and the surface is paint-coated. Self-retention wheels are installed to ensure that the bench is flexible, reliable and endurable. 7. Equipped with intelligent fault setting and appraisal system, include fault setting, troubleshooting and assessment functions etc. iii.
