Abstract

A weight distribution system used with a hitch on a vehicle and a trailer, the weight distribution system comprising a jack with a foot attached to and configured to raise and lower a front portion of the trailer; a moment bar with a forward end attached to the hitch so as to pivot about a generally vertical axis, and a rearward portion, the moment bar configured to exert a forward moment on the vehicle in response to an upward force on the rearward portion; an engagement member positioned between the jack and the rearward portion, whereby the jack can exert the upward force on the rearward portion; wherein the engagement member comprises at least one arced surface whereby the engagement member maintains the upward force on the rearward portion despite vertical or horizontal pivoting between the vehicle and the trailer is disclosed.

First claim

What is claimed is:

1. A weight distribution hitch system, comprising:
a moment bar with a forward end attached to the hitch so as to pivot about a generally vertical axis, and a rearward portion, the moment bar configured to exert a forward moment on the vehicle in response to an upward force on the rearward portion; and
at least one first rounded cam on the moment bar to prevent sliding and wear.

2. The system of claim 1 , wherein the at least one first rounded cam is aligned to allow vertical pivoting.

3. The system of claim 1 , further comprising at least one second rounded cam that is aligned to allow horizontal pivoting.

4. The system of claim 1 , further comprising at least one second rounded cam engaged with the first rounded cam wherein the at least one first rounded cam is aligned to allow vertical pivoting and the at least one second rounded cam is aligned to allow horizontal pivoting.

5. The system of claim 1 , further comprising a sensor adapted to measure the upward force on the rearward portion of the moment bar.

6. The system of claim 5 , wherein the sensor is an amperage meter configured to read the amperage on the motor adapted to apply an upward force to the rearward portion of the moment bar.

7. The system of claim 5 , wherein the sensor is a voltmeter configured to read the voltage on the motor adapted to apply an upward force to the rearward portion of the moment bar.

8. The system of claim 5 , wherein the sensor is a scale.
