SUSPENSION FOR HEAVY DUTY TRUCK USING AIR SPRING

摘要

A suspension for a heavy duty vehicle using an air spring is provided to easily attach a hanger bracket and an A-arm to a lower frame by temporarily fixing an A-arm bracket to the lower frame before attaching the hanger bracket to the lower frame. A suspension for a heavy duty vehicle comprises an A-arm bracket and a hanger bracket(16). The A-arm bracket includes a fixing plate having a fixing hole formed at upper/lower ends of the fixing plate, a temporary fixing hole formed in the two middle sides of a first surface of the fixing plate and an A-arm fixing member protruding from the middle of a second surface of the fixing plate. The hanger bracket includes a fixing plate(160), which has a fixing hole(160a) corresponding to the fixing hole of the A-arm bracket, and a coupling slot(164). The fixing plate includes a first surface on which a fixing slot(161) is formed corresponding to the fixing hole(160a), a second surface on which a bolt head-receiving hole(162) is formed in the two middle sides of the fixing plate, and a lower surface from which a fixing leg(163) extends.
