COUPLED TORSION BEAM AXLE TYPE REAR SUSPENSION DEVICE FOR A CAR TO PREVENT THE DAMAGE AND CRACK OF A TORSION BEAM AXLE

摘要

PURPOSE: A coupled torsion beam axle type rear suspension device for a four-wheel 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 torsion beam supporting apparatus(10). The torsion beam supporting apparatus is connected to the one side of a torsion beam axle(2). One side of the torsion beam supporting apparatus is connected to a car body. The torsion beam supporting apparatus comprises a supporting rod(11) and a supporting spring(12). The lower portion of the supporting rod is coupled with a torsion beam axle and the upper side of the supporting rod is projected to a car body. The lower portion of the supporting spring is coupled with the supporting rod and the upper portion of the supporting spring is connected to a car body.;COPYRIGHT KIPO 2012
