Benefits of technology

[0008]Using this system the flaps are not torn and hold the asphalt in place as the loading trucks dump asphalt into the hopper. As a result, the hopper flap system lasts longer and does not allow the asphalt to fall out of the hopper as the hopper is being loaded.

Problems solved by technology

As a result, the hopper flap system lasts longer and does not allow the asphalt to fall out of the hopper as the hopper is being loaded.

Embodiment Construction

[0012]The paver hopper flap suspension system of the present invention has a number of flaps attached to the hopper frame. A cable restraint line is attached to the flaps. A tensioning system is attached to the cable restraint line. The tensioning system allows the flaps to distort as the loading truck body engages the hopper entrance. Once the truck exits the hopper entrance the hopper flap suspension system causes the flaps to spring back to their original shape. The suspension system may include a torsion spring biasing the flaps into a vertical position. The tensioning system may include a tension adjuster. Using this system the flaps are not torn and hold the asphalt in place as the loading trucks dump asphalt into the hopper.

[0013]FIG. 1 is a side view of a paver 10 in accordance with one embodiment of the invention. The paver 10 has a chassis 12 that moves on tracked wheels 14 over the ground 16. A hopper 18 is attached to the chassis 12. The hopper 18 holds the asphalt 20. T...

Description

RELATED APPLICATIONS[0001]Not ApplicableSTATEMENT REGARDING FEDERALLY SPONSORED RESEARCH[0002]Not ApplicableTHE NAMES OF THE PARTIES TO A JOINT RESEARCH AGREEMENT[0003]Not ApplicableREFERENCE TO A SEQUENCE LISTING, A TABLE, OR A COMPUTER PROGRAM LISTING[0004]Not ApplicableBACKGROUND OF THE INVENTION[0005]The present invention is related to asphalt paving machines or pavers. Presently all asphalt pavers have stiff rubber flaps that are bolted to the sides of the entrance of the hopper box. The entrance of the hopper box is where the paver is loaded with asphalt. The trucks carrying the hot asphalt from the asphalt plant to the paver have dump beds that vary in height and width and have differing angles of dump that engage the hopper entrance. This variability results in harsh contact with the hopper flaps that are intended to retain the asphalt in the hopper and prevent spillage out of the hopper. As a result, within the first 100 hours of operation of a new paver with new flaps, the...
