Abstract

An embodiment of the present invention provides an improved upper arm and shock absorber mounting bracket and a vehicle frame including same, which can reduce the number of components, make assembly convenient, and reduce the number of assembly steps. An upper arm and shock absorber mounting bracket according to an aspect of the present invention comprises: a central supporting portion forming a flat surface portion, on which a shock absorber is supported, by pressing and forming a tube member; side supporting portions formed by being bent downwardly from both sides of the central supporting portion, in which both ends of an upper arm are mounted on the side supporting portions to support the other end of the shock absorber and to be coupled to a wheel; and vehicle mounting portions forming by being bent from the side supporting portions.

First claim

The invention claimed is:

1. An upper arm and shock absorber mounting bracket comprising:
a central supporting portion forming a flat surface portion, on which a shock absorber is supported, by pressing and forming a tube member;
side supporting portions formed by being bent downwardly from both sides of the central supporting portion, in which both ends of an upper arm are mounted on the side supporting portions to support the other end of the shock absorber and to be coupled to a wheel; and
vehicle mounting portions formed by being bent from the side supporting portions,
wherein each of the side supporting portions comprises:
a mounting hole formed to penetrate such that the upper arm is inserted into the mounting hole; and
a pair of shaft insertion holes formed to be perpendicular to the mounting hole, and allowing a rotary shaft supporting the upper arm, inserted into the mounting hole, to be inserted into the pair of shaft insertion holes, such that the upper arm is rotatable upwardly and downwardly.

2. The upper arm and shock absorber mounting bracket of claim 1 , further comprising a circular groove portion formed in a center of the central supporting portion to allow an end portion of the shock absorber to be seated and accommodated.

3. The upper arm and shock absorber mounting bracket of claim 1 , wherein the tube member is formed of twinning induced plasticity (TWIP) steel.

4. A vehicle frame comprising:
a frame body portion provided to support a lower portion of a vehicle; and
the upper arm and shock absorber mounting bracket according to claim 1 mounted on one side of the frame body portion.

5. The vehicle frame of claim 4 , wherein the frame body portion comprises through holes allowing the vehicle mounting portions of the upper arm and shock absorber mounting bracket to be inserted into the through holes through through holes and then fixed to the frame body portion, using welding.

6. The vehicle frame of claim 5 , wherein the frame body portion comprises a quadrangular tube member on at least one side thereof, and the through holes are formed through at least one side surface of the quadrangular tube member.

7. The vehicle frame of claim 4 , wherein the upper arm and shock absorber mounting bracket is fixed to the frame body portion on at least one side surface of the vehicle mounting portions, using welding, so as to be coupled to the frame body portion.

8. The vehicle frame of claim 4 , further comprising connection reinforcing members interposed between the frame body portion and the central supporting portion of the upper arm and shock absorber mounting bracket.

9. A vehicle frame comprising:
a frame body portion provided to support a lower portion of a vehicle; and
the upper arm and shock absorber mounting bracket according to claim 2 mounted on one side of the frame body portion.
