VEHICLE HEIGHT CONTROL SYSTEM OF A COMMERCIAL VEHICLE TO CHANGE THE VEHICLE HEIGHT ACCORDING TO DRIVING SPEED

摘要

PURPOSE: A vehicle height control system of a commercial vehicle is provided to conveniently adjust the height of a vehicle according to the driving speed by generating a pulse control signal for a vehicle height control switch according to the driving speed and other driving conditions. ;CONSTITUTION: A vehicle height control system of a commercial vehicle comprises four pneumatic springs(10), a leveling valve(20), a magnetic valve(30), a height control switch(40), and an air tank(50). The four pneumatic springs are installed corresponding to each other on the underside of a commercial vehicle. The leveling valve is connected to the pneumatic springs and controls the balance of air volume sucked and discharged. The magnetic valve is connected between the pneumatic springs and the leveling valve and electrically controls the air volume sucked into and discharged from the pneumatic springs. The height control switch is electrically connected for adjustment of the magnetic valve and transmits a pulse control signal. The air tank is linked with the leveling valve and the magnetic valve and supplies air to the pneumatic springs.;COPYRIGHT KIPO 2011
