SYSTEM, METHOD, AND APPARATUS TO PREVENT COMMERCIAL VEHICLE ROLLOVER
First Claim
1. A rollover prevention apparatus, comprising:
- a primary hydraulic cylinder attached to a frame bracket;
a secondary hydraulic cylinder attached to the primary hydraulic cylinder and a wheel bracket; and
at least one stabilizing wheel affixed to the wheel bracket,wherein the frame bracket is affixed to a frame such that the primary hydraulic cylinder is at an upward angle,wherein the at least one stabilizing wheel is substantially in line with a plurality of wheels affixed to the frame while the primary hydraulic cylinder and the secondary hydraulic cylinders are retracted, the line being substantially perpendicular to the primary hydraulic cylinder and the secondary hydraulic cylinders,wherein the at least one stabilizing wheel has a negative camber angle with respect to the plurality of wheels while the primary hydraulic cylinder and the secondary hydraulic cylinders are retracted, andwherein a rollover event may be averted by extending the primary hydraulic cylinder and the secondary hydraulic cylinders such that the stabilizing wheel makes contact with a road without substantially leaving a lane, and further using at least the secondary hydraulic cylinder to push against the road until the rollover event has been averted.

Abstract
A rollover prevention apparatus includes a primary hydraulic cylinder attached to a frame bracket, a secondary hydraulic cylinder attached to the primary hydraulic cylinder and a wheel bracket. The rollover prevention apparatus includes a stabilizing wheel affixed to the wheel bracket. The stabilizing wheel is substantially in line with a plurality of wheels affixed to the frame while the primary and secondary hydraulic cylinders are retracted, the line being substantially perpendicular to the primary and secondary hydraulic cylinders. The stabilizing wheel has a negative camber angle with respect to the plurality of wheels while the primary and secondary hydraulic cylinders are retracted. A rollover event may be averted by extending the primary and secondary hydraulic cylinders such that the stabilizing wheel makes contact with a road without substantially leaving a lane, and using the secondary hydraulic cylinder to push against the road until the rollover event has been averted.
