TORSION BEAM SUSPENSION

Title:

TORSION BEAM SUSPENSION

Document Type and Number:

WIPO Patent Application WO/2006/095386

Kind Code:

A1

Abstract:

A torsion beam suspension in which an opening end surface of a trailing arm rear end is butt-welded to a spindle support plate. A front bent flange (13F) and a rear bent flange (13R) are integrally and continuously provided at the front end of a plate body (13M) of a spindle support plate (13) and the rear end of the plate body (13M), respectively. The front bent flange (13F) is extended forward along a rear end outer surface of a trailing arm (10) and welded (w3) at its front end edge to the rear end outer surface. The rear bent flange (13R) is engaged with and welded (w4) to a rear end edge of the trailing arm (10). A spindle base plate (14b) is superposed on and fixed (w2) to the outer surface of the plate body (13M) and has four screw holes (Sfu, Sfd, Sru, Srd) positioned to the front and right, and above and below a spindle axis, the four screw holes being used for fixing a brake-related plate like part (P) to the spindle base plate (14b) with bolts. The spindle support plate can be reduced in wall thickness while influence of strain caused by welding heat suppressed, and as a result, the spindle plate support is reduced in weight and cost.
