Abstract

The present disclosure provides an apparatus, a system for a under-run protection device for a vehicle comprising a first beam member extending laterally to the direction of the vehicle, wherein a partial portion of the first beam has a corrugated cross-section. A second beam member mounted on the first beam member positioned and adapted to absorb an impact from another vehicle by deforming when the impact force exceeds a predetermined level, further the partial corrugated cross-section of the first beam member enables reduction in construction/manufacturing material for the said second beam member. A plurality of brackets characterized by a L-shape, joined to the first beam member at one arm of the L-shape and with the vehicle at other arm of the L-shape.

Claims

1. A under-run protection device system for a vehicle comprising:

a first beam member extending laterally to the direction of a vehicle wherein a partial portion of the first beam member has a corrugated cross-section;

a second beam member mounted on the first beam member positioned and adapted to absorb an impact from another vehicle by deforming when the impact force exceeds a threshold value, further the partial corrugated cross-section of the first beam member enables reduction in construction/manufacturing material for the said second beam member; and

a plurality of L-shaped brackets, wherein a one arm of the L-shape of each of the plurality of L-shaped brackets is joined to the first beam member, wherein an other arm of the L-shape of each of the plurality of L-shaped brackets is joined to a vertical member, wherein vertical member is riveted to the vehicle via a connecting bracket, wherein the one arm of the L-shape is parallel to the first beam member, wherein the other arm of the L-shape is perpendicular to the first beam member, and wherein the one arm of each of the plurality of L-shaped brackets is welded in the trough of the first beam member having corrugated cross-section.

2. The under-run protection device system for a vehicle of claim 1, wherein the length of the plurality of L-shape bracket is directly proportional to a weight carrying capacity of the vehicle.

3. The under-run protection device system for a vehicle of claim 1, wherein a displacement of at least 400 millimeter by the first beam member is resisted by the plurality L-shaped bracket.

4. The under-run protection device system for a vehicle of claim 1, wherein the partial corrugated first beam member has a Yield Limit of at least 255 mega Pascal (MPa).

5. The under-run protection device system for a vehicle of claim 1, the second beam member is mounted on the first beam member via a welding to the first beam member.

6. The under-run protection device system for a vehicle of claim 1, the threshold value is determined by a set of regulation issued by the transportation department or transport governing bodies of a country.

7. The under-run protection device system for a vehicle of claim 1, the partial corrugated cross-section comprises of a plurality of crests and a plurality of troughs.

8. The under-run protection device system for a vehicle of claim 7, the plurality of crests and the plurality of troughs have a uniform size.
