Abstract

A trailing arm mounting structure for a space frame vehicle includes: a trailing arm mounting portion configured to mount a trailing arm; a side sill including a rear portion on which the trailing arm mounting portion is mounted; and a rear pillar connected to an upper rear portion of the side sill.

First claim

What is claimed is:

1. A trailing arm mounting structure for a space frame vehicle, the trailing arm mounting structure comprising:
a trailing arm mounting portion configured to mount a trailing arm;
a side sill including a rear portion on which the trailing arm mounting portion is mounted;
a rear pillar connected to an upper rear portion of the side sill; and
a rear side member connected to a side of the side sill,
wherein the trailing arm mounting portion comprises an outer bracket including a first surface and a second surface,
wherein the first surface of the outer bracket is disposed to an outer side of the side sill, and the second surface of the outer bracket is attached to an end of the rear side member and an end of the side sill.

2. The trailing arm mounting structure of claim 1 , wherein the trailing arm mounting portion comprises:
an inner bracket connected to an inner side of the side sill.

3. The trailing arm mounting structure of claim 2 , wherein the side sill, the inner bracket and the outer bracket are configured to form a mount space in which the trailing arm is mounted.

4. The trailing arm mounting structure of claim 3 , wherein:
the side sill includes:
a side sill upper portion; and
a side sill inner portion bent toward an inside of a vehicle body from the side sill upper portion,

the inner bracket is connected to the side sill inner portion, and
the outer bracket is connected to the side sill upper portion.

5. The trailing arm mounting structure of claim 2 , further comprising a floor member coupled to an inside of the side sill,
wherein an upper part of the inner bracket is connected to a lower part of the floor member.

6. The trailing arm mounting structure of claim 5 , wherein the floor member includes a curved portion curved upward, and the rear pillar is connected to the curved portion.

7. The trailing arm mounting structure of claim 1 , further comprising a rear pillar bracket supporting the rear pillar and the upper rear portion of the side sill.

8. The trailing arm mounting structure of claim 7 , wherein the rear pillar bracket includes a rear pillar side portion that is inclined toward an upper side of the side sill from the rear pillar.

9. The trailing arm mounting structure of claim 1 , wherein:
