Abstract

The axle assembly has an elongated shaft that is connected to a mounting bracket. A first end of an arm is connected to the elongated shaft. The arm extends rearwardly from the elongated shaft and connects to a bearing bracket at a second end. The bearing bracket has a pair of flanges and a pin that passes through the flanges and is received within an opening of a rotatable arm. The rotatable arm is connected to an axle.

Claims

1. An axle assembly comprising:

an elongated shaft;

a mounting bracket connected to the elongated shaft;

an arm connected having a first end connected to an end of the elongated shaft and extending rearwardly;

a bearing bracket having a pair of flanges connected to a second end of the arm;

a pin disposed between the pair of flanges and received in an opening of a rotatable arm; and

an axle connected to the rotatable arm.

2. The axle assembly of claim 1 further comprising a bearing disposed within the pair of flanges.

3. The axle assembly of claim 1 wherein the rotatable arm is generally L-shaped.

4. The axle assembly of claim 1 further comprising a link assembly connected to the bearing bracket and mounting bracket.

5. The axle assembly of claim 4 further comprising the link assembly having a link connected to a support arm and a support bracket.

6. The axle assembly of claim 5 wherein the support arm is connected to the bearing bracket.

7. The axle assembly of claim 5 wherein the support bracket is connected to the mounting bracket.

8. The axle assembly of claim 4 wherein the link assembly is adjustable.

9. The axle assembly of claim 1 further comprising an actuating bar connected to the rotatable arm.

10. The axle assembly of claim 9 wherein the actuating bar is generally parallel to the shaft and below the mounting bracket.

11. The axle assembly of claim 10 further comprising an actuating member connected at one end to the actuating bar and a vehicle frame at a second end.

12. The axle assembly of claim 11 further comprising a sensor connected to the actuating member that is in communication with a controller.

13. The axle assembly of claim 12 wherein the controller determines the angle of a front wheel based on a signal from the sensor.

14. The axle assembly of claim 13 wherein the controller actuates the actuating member to turn the axel such that the angle of the axle complements the angle of the front wheel.

15. The axle assembly of claim 12 wherein the controller monitors speed to lock the axle in a straight position when at a predetermined speed.
