COUPLED TORSION BEAM AXLE TYPE REAR SUSPENSION DEVICE FOR A CAR TO TUNE RIDE QUALITY EASILY ACCORDING TO THE WEIGHT AND DRIVING CONDITION OF A CAR

摘要

PURPOSE: A coupled torsion beam axle type rear suspension device for a car is provided to minimize the elastic distortion angle of the both sides of a torsion beam axle through improving the supporting structure of a torsion beam axle directly connected to a car body.;CONSTITUTION: A coupled torsion beam axle type rear suspension device for a car comprises a piston rod member(21), a cylinder member(22), and a lateral load(23). The lower sides of the piston rod member are coupled with the both upper sides of a torsion beam axle into one body. The upper side of the piston rod member is projected to a car body above a torsion beam axle. The cylinder member is installed for the piston rod member to be inserted into lower side. The upper side of the cylinder member is coupled with a car body into one body. The cylinder member guides the moving of the piston rod member. The lateral load connects the cylinder member.;COPYRIGHT KIPO 2012
