## Abstract

An air suspension for a vehicle includes a mounting bracket configured to couple to the vehicle. A pivot bracket includes a top and a bottom. The top is pivotably coupled to a frontward portion of the mounting bracket. An air shock absorber includes a first end and a second end. The first end is pivotably coupled to the bottom of the pivot bracket and the second end is pivotably coupled to a rearward portion of the mounting bracket. An axle arm includes a first portion and a second portion. The first portion of the axle arm is fixedly coupled to the frontward portion of the mounting bracket. A spindle is fixedly coupled to the second portion of the axle arm and is configured to be coupled to a hub assembly of a wheel.

## Claims

### Claim 1

An air suspension comprising:
a mounting bracket configured to couple to a vehicle;
a pivot bracket comprising a top and a bottom, wherein the top is pivotably coupled to a frontward portion of the mounting bracket;
an air shock absorber comprising a first end and a second end, wherein the first end is pivotably coupled to the bottom of the pivot bracket and the second end is pivotably coupled to a rearward portion of the mounting bracket;
an axle arm comprising a first portion and a second portion, wherein the first portion of the axle arm is fixedly coupled to the frontward portion of the mounting bracket; and
a spindle comprising a first end and a second end, wherein the first end of the spindle is fixedly coupled to the second portion of the axle arm, and the second end is configured to be coupled to a hub assembly of a wheel.

### Claim 2 (depends on 1)

The air suspension of claim 1, further comprising:
a pivot axle rotatably coupled to the frontward portion of the mounting bracket by bushings, wherein a first end of the pivot axle is fixedly coupled to the first portion of the axle arm, and the top of the pivot bracket is fixedly coupled to the pivot axle.

### Claim 3 (depends on 1)

The air suspension of claim 1, wherein the bottom of the pivot bracket comprises a fork comprising aligning openings, wherein the first end of the air shock absorber comprises an aligning opening disposed within the fork, wherein a bolt is disposed within the aligning openings, pivotably coupling the pivot bracket to the air shock absorber.

### Claim 4 (depends on 1)

The air suspension of claim 1, wherein the rearward portion of the mounting bracket comprises aligning openings and the second end of the air shock absorber comprises an aligning opening, wherein a bolt is disposed within the aligning openings, pivotably coupling the second end of the air shock absorber to the mounting bracket.

### Claim 5 (depends on 1)

The air suspension of claim 1, wherein the air shock absorber comprises telescoping tubing and an inlet to receive air pressure.

### Claim 6 (depends on 5)

The air suspension of claim 5, wherein psi within the air shock absorber is adjustable via the inlet.

### Claim 7 (depends on 1)

The air suspension of claim 1, wherein the mounting bracket is coupled to a cross beam of a trailer.
