Steering systems
The present application pertains to a system comprising a multi-axle trailer with a front and a rear. The a multi-axle trailer comprises at least one lift axle configured to be raised or lowered to distribute weight, to increase trailer deflection during a turn, or both. A jeep is mounted between the trailer and a tractor wherein the jeep is configured to decrease weight on one or more axles. A booster is mounted to the rear of the multi-axle trailer. The system is configured such that during raising of the at least one lift axle an increase in air pressure to one or more other axles is increased to offset weight.
1 . A system comprising:
a multi-axle trailer with a front and a rear wherein the multi-axle trailer comprises at least one lift axle configured to be raised or lowered to distribute weight, to increase trailer deflection during a turn, or both;
a tractor;
a jeep mounted between the trailer and tractor wherein the jeep is configured to decrease weight on one or more axles;
a booster mounted to the rear of the multi-axle trailer;
wherein the system is configured such that during raising of the at least one lift axle an increase in air pressure to one or more other axles of the multi-axle trailer is employed to offset weight;
wherein the booster comprises a front section, a rear section, and hydraulic cylinders therebetween;
wherein the booster comprises a front section, a rear section, and hydraulic cylinders therebetween; wherein the hydraulic cylinders are configured to create a pivoting motion on the rear booster section to apply vertical forces on the front and rear sections relative to each other and apportion weight.
2 . The system of claim 1 which further comprises one or more valves connected to one or more air tanks to increase the air pressure to the one or more other axles of the multi-axle trailer.
3 . The system of claim 2 wherein the one or more valves are pneumatically powered.
4 . The system of claim 2 wherein the one or more valves are hydraulic valves.
5 . The system of claim 2 wherein the one or more valves are electric valves.
6 . The system of claim 2 wherein the one or more valves are pneumatically powered, hydraulic, electric, or a combination thereof.
7 . The system of claim 1 wherein the booster mounted to the rear of the multi-axle trailer is configured to be lifted and avoid contact with the ground via pneumatic power, hydraulic power, electric power, or a combination thereof.
8 . The system of claim 7 wherein the multi-axle trailer is configured such that any one or more axles of the multi-axle trailer may be lifted from the ground.
9 . The system of claim 1 further comprising independently controlled axles.
10 . The system of claim 1 which further comprises a horizontal pivoting hinge in mechanical connection with at least one of the hydraulic cylinders such that when the at least one of the hydraulic cylinders is extended, the horizontal pivoting hinge pushes on the rear portion of the booster to create additional downward force on the rear booster section.
