Semitrailer load balancing system
First Claim
1. An adjustment system for adjusting a sliding undercarriage along a length of a semitrailer and adjusting a sliding fifth wheel along a length of a tractor, the tractor used for pulling the semitrailer, the semitrailer having an air operated brake, the adjustment system is used for balancing a load on the semitrailer, adjusting the turning radius and for operator convenience, the adjustment system comprising:
- a communication and control module with control panel and display;
sliding undercarriage adjustment means connected to said communication and control module for adjusting the sliding undercarriage forward and aft on the semitrailer when said sliding undercarriage adjustment means is actuated by said control module, whereby said sliding undercarriage adjustment means is adapted for mounting on the semitrailer and connected to the air operated brake; and
a load balancing switch connected to said control module and connected to an air pressure switch, whereby said air pressure switch adapted for connection to the air operated brake and whereby when said load balancing switch is pushed said sliding undercarriage adjustment means is actuated for adjusting the sliding undercarriage forward and aft when the semitrailer'"'"'s air operated brake has been disengaged.

Abstract
A system for adjusting a sliding undercarriage along a length of a semitrailer and adjusting a sliding fifth wheel along a length of a tractor. The tractor used for pulling the semitrailer. The system is used for balancing a load on the semitrailer, adjusting the truck and semitrailer turning radius and for operator convenience. The sliding undercarriage and sliding fifth wheel may be adjusted from the cab of the tractor when the tractor and trailer are in operation. The system includes a control panel under computer control. The control panel is received inside the cab of the tractor and electrically connected to a first electric motor and first gear box mounted on the tractor. The first gear box drives a pair of parallel screws threadably attached to a pair of ball screws. The ball screws are secured to the fifth wheel of the tractor. When the first gear box is actuated, the screws attached to the fifth wheel move the fifth wheel forward and aft on the tractor. The control panel is also electrically connected to a second electric motor and second gear box mounted on the trailer. The second gear box drives a pair of elongated parallel screws threadably attached to a pair of ball screws. The ball screws are secured to the sliding undercarriage mounted underneath the semitrailer. When the second gear box is actuated, the screws move the sliding undercarriage forward and aft on the trailer. The control box is designed for receiving satellite communications and audio communications for adjusting trailer weight requirements when traveling interstate.
