TORSION BEAM TYPE SUSPENSION
Document Type and Number:
Japanese Patent JP2019172201
Kind Code:
A
Abstract:
To prevent melt-down of a tip when welding a fork-shaped reinforcing member for reinforcing connection of a trailing arm and a torsion beam, and to make positioning of an attachment position easy.SOLUTION: A torsion beam type suspension comprises: a pair of trailing arms which is arranged with an interval in a vehicle width direction; a torsion beam linearly extending to the vehicle width direction, and connected to the trailing arm at both ends in an extension direction; and a reinforcing member for reinforcing a connecting part to which the trailing arm and the torsion beam are connected. The torsion beam extends in a gutter shape, the reinforcing member extends in a gutter-shaped portion of the torsion beam so as to be split to a fork part toward a tip part from a base end part, and joined to the trailing arm at the base end part. The vicinity of the tip part of the reinforcing member has a protrusion protruding to an inside of the fork part, and joined to an inner face of the gutter-shaped portion of the torsion beam at both outer sides of the fork part.SELECTED DRAWING: Figure 3
