BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a rear suspension mounting structure of a vehicle having a suspension link extending in the vehicle body transverse direction, and more particularly, to a mounting structure of a vehicle body connection end of a suspension link.

As a rear suspension of an automobile, for example, as disclosed in Japanese Patent Application Laid-Open No. 62-117104, a so-called suspension link having one end connected to a wheel support member for supporting the wheel rotatably on the other end and the other end is so-called. Multiple link forms are known.

In rear linkages in the form of multiple links, the suspension links can be variously coupled and installed. For example, in a suspension upper link located above any other suspension link, it is proposed to have a link extending substantially in the front-rear direction of the vehicle body. The upper link of the suspension is positioned relatively high and extends substantially in the transverse direction of the vehicle body, thereby connecting it to the vehicle body at its body side connection end, in particular at the rear wheel house panel portion of the wheel house.

The suspension link is preferably connected to have sufficient support rigidity to prevent noise or vibration due to the load input to the vehicle body through the suspension link or to prevent the suspension link from protruding into the vehicle compartment in the event of a collision. Therefore, it is necessary to connect to the vehicle body so as to have sufficient support rigidity when the vehicle body side connection end forms a suspension linkage extending in the vehicle body transverse direction located near the rear wheel housing panel.

The present invention has been made in view of the above point, and an object of the present invention is to connect a vehicle side connection end of a suspension link extending in the transverse direction of the vehicle body to a vehicle body near the rear wheel house panel to have a suitable supporting strength.

The structure of the rear wheel house portion 14 as the structure of the vehicle body B on which the rear suspension 10 is mounted with respect to the rear right wheel RR will be described below.

As shown in FIG. 3, the rear wheel house portion 14 is formed from the rear quarter panel 38 in which the rear wheel house inner portion 36 and the vehicle body transverse outer end of the rear wheel house inner 36 are joined. And a lower end of the rear wheelhouse interior 36 is connected to the outer end of the rear bottom 40 at the rear of the vehicle body.

The upper and lower ends of the rear quarter panel 38 are coupled to the rear wrench located outside the panel 38 in the lateral direction of the vehicle body.

The rear quarter panel 38 and the rear fender 42 form a space 44, and a belt reinforcement 46 is provided in the closed space 44 to improve the strength of the vehicle body B. As shown in FIG.

The upper end of the belt reinforcement 46 shown in FIG. 6 is sandwiched and welded between the upper end of the rear quarter panel 38 and the rear fender, and the lower quarter panel 38 is welded to the middle portion.
