Embodiment Construction

[0025] Below, refer to the accompanying drawings ( Figure 1 to Figure 5 ) describes one embodiment of the suspension structure of the present invention. The suspension structure of the present embodiment is a torsion beam type suspension structure in which a pair of rear swing arms 20 are connected by a torsion beam 10 . In addition, this suspension structure is a type that does not have a stabilizer bar arranged inside the torsion beam 10 .

[0026] like figure 1 As shown, the torsion beam type suspension 5 of this embodiment is a member that supports the left and right wheels 3 (rear wheels in this example) of the vehicle so that the wheels 3 can swing relative to the vehicle body 1 in the vertical direction of the vehicle. Torsion beam 10 , spring seat 40 and a pair of rear swing arms 20 . like figure 1 As shown, the portion of the rear swing arm 20 located at the rear of the vehicle is connected to the wheel 3 , and the portion of the rear swing arm 20 located at th...

Abstract

The present invention provides a torsion beam type suspension structure for a vehicle for alleviating stress concentration at a portion where a reinforcing member is connected to a torsion beam. A rear swing arm (20) is joined to both ends of the torsion beam (10). The outer wall surface (11a) of the torsion beam (10) is provided with a seat joint (13) engaged with the spring seat (40), and the inner wall surface of the torsion beam (10) near the opening edge (15a) of the opening (11b) is joined with a reinforcement (30) that closes a part of the opening (15). The reinforcing member (30) extends from the outer side of the torsion beam (10) to the inner side of the inner side end of the seat joint (13), and the opening side bending part (32) of the inner side of the reinforcing member (30) is in contact with the inner wall surface ( 11b) Bending from the vicinity of the opening edge (15a) to the inner side of the opening (15) in the connected state.

Description

technical field [0001] The present invention relates to a torsion beam suspension structure in which a pair of rear swing arms are connected by a torsion beam. Background technique [0002] In order to reduce the weight of the automobile body, the weight reduction of each part of the car body is promoted. For example, in order to reduce the weight of a torsion beam suspension, studies have been made on reducing the plate thickness of each member constituting the suspension. When reducing the thickness of each member, in order to compensate for the reduction in strength due to the thinning, it is necessary to configure the structure to disperse stress. Alternatively, a reinforcing plate may be added to a thinned member. [0003] A torsion beam type suspension includes a pair of rear swing arms arranged in the vehicle width direction of a vehicle body and a torsion beam connecting the pair of rear swing arms. As a technique for alleviating stress concentration at the joint ...
