Abstract

PURPOSE:To omit a lateral rod in a rear wheel suspending apparatus of an FF type automobile, by arranging, between a torsion beam and a planar trailing arm that are secured, an auxiliary arm to exend adjacent the position where the arm supports the car body. CONSTITUTION:One end of the planar trailing arm 4 is attached to the rear open type U-shaped torsion beam 2 with the surface of the arm 4 vertical to the beam 2. The planar auxiliary member 7 extends between the torsion beam 2 and the trailing arm 4 to join the beam 2 and the arm 4. Said auxiliary member 7 extends to the car body support section 6 of the trailing arm 4, and is arranged normally to the surface of the trailing arm 4. According to this arrangement, the lateral stiffness is improved, the bending distortion can be decreased, and use of a lateral rod can be excluded.

Ｖ連結する必要があった。Conventionally, this type of zero suspension system has been divided into two types: an axle suspension type and an independent suspension type.
There is one in which the axle is M-mounted via a trailing arm or a lead-in arm. In a device suspended via this arm, it is economical to construct the arm from a plate-like member, and the plate-like member is arranged so that the plate surface is vertical. In such a configuration, since the arm, that is, the plate-shaped portion, has low lateral rigidity, it is necessary to connect the arm and the vehicle body with a V-connection using a lateral rod in order to prevent the vehicle body from wobbling laterally.

目的とする。SUMMARY OF THE INVENTION An object of the present invention is to provide a structure in which a trailing arm is used in a suspension system in which the trailing arm is constructed of a plate-like member and does not require a lateral rod.

。That is, the suspension system of the present invention includes a torsion beam having wheel support sections at both ends, one end of the torsion beam fixed near the wheel support section, and the other end pivotably supported so that the plate surface is approximately vertical. The reinforcing member is welded to the plate surface of the trailing arm, and the reinforcing member is welded to the plate surface of the trailing arm. It is characterized by extending to the vicinity of the support part. In order to enhance the reinforcing effect, the reinforcing member is preferably configured to be connected to the vehicle body support portion.

る。According to the configuration of the present invention described above, the reinforcing member that connects the torsion beam and the trailing arm is disposed. bending in this direction can reduce deformation. The reinforcing effect is achieved by extending the reinforcing member to the vehicle body support part of the trailing arm.
If it is connected to the vehicle body support part by a welded cape, it can be further improved. Therefore, there is no need to use a lateral rod as in the conventional case, and the structure becomes simpler.
