（実開昭60−158906号公報）。(Prior art) Since longitudinal and lateral forces act on the suspension arm of a vehicle while the vehicle is running, and these forces are transmitted to the vehicle body, it is necessary to increase the rigidity of the joint between the suspension arm and the vehicle body. . As one of the countermeasures, it has been proposed to connect the left suspension arm to the vehicle body with a rigid member to the right suspension arm and the vehicle body. Publication No. 158906).

う。 By the way, in order to eliminate the poor workability caused by directly connecting the suspension arm to the vehicle body, and to more effectively suppress vibrations transmitted from the suspension arm, a suspension member is installed between the suspension arm and the vehicle body. intervene,
Suspensions have been implemented in which a suspension arm is coupled to a suspension member, and the suspension member is coupled to a vehicle body. In this suspension as well, it is possible to use a rigid member to increase the rigidity of the joint between the suspension arm and the suspension member, as in the above proposal, but this would increase the number of parts.

ム１４，１６を支持する。(Problem to be solved by the invention) For example, in a suspension member used in a dual-link suspension, only the suspension arm is connected to the suspension member and no differential device is connected to the suspension member. is suspension member 10
As shown in FIG. 5, it consists of a pair of side parts 11a spaced apart in the lateral direction of the vehicle body, and a cross part 11b arranged in the lateral direction within the space, and has an approximately H-shape in plan view. It is formed by bending a plate material as shown. This suspension member 1
0 is attached to the vehicle body by connecting portions 12 provided at intervals before and after each side portion 11a, and supports left and right suspension arms 14, 16 by a cross portion 11b.

８の剛性は横方向の荷重に対して低い。 In the suspension member 10 of the above type, the support rigidity of the wheel increases as the span S 1 between the front and rear coupling parts 12, 12 of each side part becomes larger, and the front and rear links 17 of each suspension arm increase.
The larger the span S 2 between a and 17b, the higher it becomes. However, there is a limit to how large the span S2 of the front and rear links can be due to the need to avoid interference with the fuel tank, spare tire, and other parts. As a result, the pair of side portions 11a are separated from the cross portion 11b.
The part leading to the curved part 18 becomes the curved part 1.
8 has low rigidity against lateral loads.
本考案の目的は、車輪の支持剛性を高めること

に溶接される。(Means for solving the problem) The present invention is a suspension member that supports left and right suspension arms and is connected to the vehicle body, and is arranged in the longitudinal direction of the vehicle body at intervals in the lateral direction of the vehicle body. a pair of side members each having a connecting portion to the vehicle body, each of which is made of a plate material and has a closed cross-sectional shape, and a cross member disposed in the lateral direction of the vehicle body within the space, the cross member being for the left and right suspension arms. a cross member formed of a plate material and having a closed cross-sectional shape and having a pair of cylindrical support portions extending in the front-rear direction and spaced apart laterally; be welded to.

の剛性が高くなる。(Functions and Effects) Since the pair of side members and cross members are formed independently and then welded, it is possible to form the side members and cross members straight in a plan view. The joints between the side members and the cross member are orthogonal in plan view. In this way, the direction of the load from the suspension arm coupled to the support portion can be made parallel to the front and rear surfaces of the cross member, increasing the rigidity of the cross member.

ため、サイドメンバの変形が生じない。 Since the cross member is welded to the upper surface, lower surface, and side surface of the side member, cross-sectional deformation of the cross member is suppressed and rigidity is not reduced. Further, since the lateral force applied from the suspension arm is transmitted to and received by the entire highly rigid side member, deformation of the side member does not occur.

めることが可能である。 Since the pair of side members and cross members are formed independently, the side members can be made longer, which increases the span between the parts that connect to the vehicle body, and from this point of view as well. It is possible to increase the rigidity.
