Abstract
A lift axle system which selectively lowers (and raises) an axle. When wheels of the lift axle system are lowered to the ground, the wheels effectively work to reduce the load supported by the original axles. A percentage of the weight of the rear of the towable vehicle is transferred to the attachment point to its tractor, that is, to the front of the towable vehicle. This helps to better balance the load, making the vehicle more stable on the road. The lift axle system is easy to operate and extends the life of the base system.
Claims18
A lift axle system which is configured for mounting to a towable vehicle, said lift axle system comprising an axle and an axle deployment system which is configured to selectively deploy the axle to stabilize the towable vehicle, wherein the axle deployment system is configured to use air to lower the axle to deploy the axle, wherein the axle deployment system comprises an air booster and a pivotable arm attached to the axle and to the air booster, wherein the air booster pushes the pivotable arm to lower the axle, and wherein the axle deployment system comprises a steel cable which is configured to raise the axle when the axle is to be withdrawn, wherein the lift axle system comprises a stabilizing system configured to mitigate lateral movements of the towable vehicle when it is in motion on the road.
A lift axle system which is configured for mounting to a towable vehicle, said lift axle system comprising an axle and an axle deployment system which is configured to selectively deploy the axle to stabilize the towable vehicle, wherein the axle deployment system is configured to use air to lower the axle to deploy the axle, wherein the axle deployment system comprises an air booster and a pivotable arm attached to the axle and to the air booster, wherein the air booster pushes the pivotable arm to lower the axle, and wherein the axle deployment system comprises a steel cable which is configured to raise the axle when the axle is to be withdrawn, wherein the lift axle system comprises two base plates, one under each vehicle frame beam, wherein an assembly module is coupled to each base plate, and each assembly module comprises a single air booster, pulleys, and a pivoting arm, wherein when under pressure on the ground, will vary in height following the ground's oscillation.
A lift axle system which is configured for mounting to a towable vehicle, said lift axle system comprising an axle and an axle deployment system which is configured to selectively deploy the axle to stabilize the towable vehicle, wherein the axle deployment system is configured to use air to lower the axle to deploy the axle, wherein the axle deployment system comprises an air booster and a pivotable arm attached to the axle and to the air booster, wherein the air booster pushes the pivotable arm to lower the axle, and wherein the axle deployment system comprises a steel cable which is configured to raise the axle when the axle is to be withdrawn, wherein the lift axle system comprises two base plates, wherein an assembly module is positioned and coupled under each base plate, and a mount for a single air booster is coupled to a predefined attachment point on each assembly module, wherein the mount for the single air booster is installed halfway between the attachment point of the arm and the attachment point of the axle, wherein the mount for the single air booster also includes the assembly of a pulley, which is part of the steel cable path used in the process of raising the axle.
