Abstract

The present invention is air powered lifting suspension system allowing to lower and adjust a trailer to the ground level.

Description

TITLE: Air powered lifting suspension system ABSTRACT OF THE D1SC',LOSURE:
The present disclosure refer°s to air powered lifting suspension system allowing to lower and adjust ;~ trailer to the ground level.
BACKGROUND OF THF, INVENTION:
1) Field of the invention:
The present invention relates to air powered lifting suspension system allowing to lower and adjust a trailer to the ground level.
2) Descriution of related art:
A search of prior art records has unveiled the following patents:
US 5,549,322 issued in 1996 to Hauri.
As can be seen the patent mentioned above is probably the most relevant.
The proposed system is air powered lifting suspension system allowing to lower and adjust a trailer to the ground level.
It has been discovered that the present invention described herein allows by the assembling of the components to lower and adjust a trailer to the ground level.
Brief description of the several views of the drawin~lsl:
Figure 1 is a perspective vicaw of air powered lifting suspension system;

Figure 2 is a perspective view of air powered lifting suspension system showing a lowered trailer t:o the ground level;
Figure 3 is a side view thereof;
Figure 4 is a side view of air powered lifting suspension system showing a trailer before to be lowered to the ground level;
Figure 5 is a perspective view showing the components of air powered lifting suspension system assembled to a trailer;
Figure 6 is a side view thereof; and Figure 7 is an exploded view of air powered lifting suspension system.
Detailed descriution of the invention:
Referring to the drawings in more detail, it may be seen that the present invention allows when the air is taken out from the balloons (3) to lower and adjust a trailer to the ground level.
As shown in figures 1 to 7, the air pressure of a compressor (15) is distributed independently to each lifting suspension system by means of tubes (16), which each lifting suspension system is provided with two arms (1)(2).
The first arm (1) is formed with an elongated part member including hole which is engaged into a cylindrical part member (6) including holes allowing by means of a first rod (14) and first bolt (13) to be connected to frame of trailer shown in phantom lines, and of a U-shaped member (9) including holes formed under each end of first arm (l).
The U-shaped member (9) formed under the upper end of each first arm (1) is engaged onto a connecting means formed onto each balloon (3), which allows to connected each balloon (3) to first arm (1) by means of a second rod (8) and second bolt (11;x, and which an aperture formed therein allows to a safety rod (7) to pass through first arm (1) and frame, and which is blocked in position by a clip member (10).
A connecting means formed under each balloon (3) is engaged into a U-shaped member (9) which allows to connect each balloon (3) to frame of trailer by means of a second rod (8) and second bolt (11).
The U-shaped member (9) formed under the lower end of each first arm (1) is engaged onto the upper connecting means formed onto each shock absorber (4), which is connected therein by means of a second rod (8) and second bolt (11).
The lower connecting means formed onto each shock absorber (4) is engaged into a L1-shaped member (9) formed on top of second arm (2), which is connected to each shock absorber (4) by means of a second rod (8) and second bolt (11).
The lower end of each second arm (2) is formed with a longer rod passing through the ring members ( 1~) and a part member (5) including spaced and aligned holes, which are maintained in position by means of second bolt (11) and connected at each wheel of trailer shown in phantom lines.
The upper end of each second arm (2) is formed with a structural part member including hole which is engaged into a cylindrical part member (6) including holes and connected to frame of trailer by means of a first rod (14) and first bolt (13).
Although only a single embodiment of the present invention has been described and illustrated, the present invention is not limited to the features of this embodiment, but includes all variations and modifications within the scope of claims attached hereto without departing from the spirit of the invention.

Claims (2)

1. Air powered lifting suspension system allowing to lower and adjust a trailer to the ground level, which comprising a first arm formed with an elongated part member including hole which is engaged into a cylindrical part member including holes allowing by means of a first rod and first bolt to be connected to frame of said trailer, and of a U-shaped member including holes formed under each end of said first arm;
said U-shaped member formed under the upper end of each said first arm is engaged onto a connecting means formed onto each balloon, which allows to connected each said balloon to said first arm by means of a second rod and second bolt, wherein an aperture formed therein allows to a safety rod to pass through said first arm and said frame, and which is blocked in position by a clip member;
a connecting means formed under each said balloon is engaged into a U-shaped member which allows to connect each said balloon to said frame of trailer by means of said second rod and said second bolt;
said U-shaped member formed under the lower end of each said first arm is engaged onto the upper connecting means formed onto each shock absorber, which is connected therein by means of said second rod and second bolt;
the lower connecting means formed onto each said shock absorber is engaged into a U-shaped member formed on top of second arm, which is connected to each said shock absorber by means of said second rod and said second bolt;

the lower end of each said second arm is formed with a longer rod passing through the ring members and a part member including spaced and aligned holes, which are maintained in position by means of said second bolt and connected at each wheel of trailer; and the upper end of each said second arm is formed with a structural part member including hole which is engaged into a cylindrical part member including holes and connected to said frame of trailer by means of said first rod and said first bolt.
2. The system of the claim 1 allows by means of a compressor to distribute independently the air pressure to each lifting suspension system by means of tubes, wherein each said lifting suspension system is provided with two arms.
