Abstract
An overload suspension system configured for operative engagement to a vehicle having a first leaf spring and second leaf spring to provide auxiliary support to the vehicle when overloaded. A first control arm attached to a first torsion bar has a distal end positioned a separation distance from the first leaf spring. A second control arm attached to the second control arm has a distal end positioned substantially the same separation distance from the second leaf spring. The suspension system operates as an auxiliary suspension only when added weight to the vehicle deflects both leaf springs to contact a respective one of the control arms, thereby preserving the ride and suspension characteristics of the vehicle when the added weight is not present.
Claims10
A vehicle overload suspension system, comprising:
- a first torsion bar, said first torsion bar having a first end in a fixed connection to a vehicle;
- a first control arm, said first control arm being elongated and extending between a first end thereof to a first distal end;
- said first end of said first control arm engaged to a second end of said first torsion bar;
- said first distal end positioned a first separation distance from a first leaf spring of a vehicle;
- a second torsion bar, said second torsion bar having a first end thereof in a fixed connection to said vehicle;
- a second control arm, said second control arm being elongated and extending between a first end thereof, to a second distal end;
- said first end of said second control arm engaged to a second end of said second torsion bar;
- said second distal end spaced a second separation distance from a second leaf spring of said vehicle;
- said first distal end contacting said first leaf spring only when a weight load of said vehicle imparts a deflection of said first leaf spring to a first contact against said first distal end;
- said second distal end contacting said second leaf spring only when said weight load of said vehicle imparts a deflection of said second leaf spring to a second contact thereof against said second distal end;
- and
- whereby said first contact rotates said first control arm to twist said first torsion bar engaged to said first end thereof, and said second contact rotates said second control arm to twist said second torsion bar engaged to said first end thereof.
An overload suspension system configured for engagement to a vehicle, comprising:
- a first torsion bar, said first torsion bar having a first end thereof engageable to a fixed connection to a vehicle;
- a first control arm, said first control arm being elongated and extending between a first end thereof to a first distal end;
- said first end of said first control arm in an engagement with a second end of said first torsion bar;
- said first distal end of said first control arm in said engagement with said second end of said torsion bar being located in an alignment with a first leaf spring of said vehicle at a first separation distance from a first leaf spring of a vehicle;
- a second torsion bar, said second torsion bar having a first end thereof engageable to a fixed connection thereof to said vehicle;
- a second control arm, said second control arm being elongated and extending between a first end thereof to a second distal end;
- said first end of said second control arm in an engagement with a second end of said second torsion bar;
- said second distal end of said second control arm in said engagement with said second end of said torsion bar being located in an alignment with a second leaf spring of said vehicle at a second separation distance from a second leaf spring of said vehicle;
- and
- wherein the positioning of said first distal end and said first separation distance from said first leaf spring and said positioning of said second distal end and said second separation distance from said second leaf spring defines a configuration of said overload suspension system for operation only when said vehicle exceeds a weight load thereof which is sufficient to impart a deflection of said first leaf spring and said second leaf spring to form contacts between said first leaf spring with said first distal end of said first control arm, and said second leaf spring with said second distal end of said second control arm.
