| Abstract | A reversible cage wheel with flat retractable lugs was
developed to provide facility for road transportation and to
improve performance in wet land operations. A pair of wheels were
constructed after testing first wheel and implementing necessary
modifications. The developed wheel had hinged , sw.i.ngi. ng t.yr>e flat
lugs, by which the outer dia meters ac h ieved were 100 millimeters
greater than the tyre when expanded and 100 millimeters smaller
when retracted. Wheel were compared with high lugged tyre and
tyre with conventional cage wheel in five soil conditions. In all
four wet soil conditions the developed cage wheel exerted more
than two times of drawbar pull and power over high lugged tyre
and 1. 5 times over conventional cage wheel. For dry soil
condition wheel exerted 1. 4 times pull and 1.1 times power over
t y re and 1. 1 times pull and more than one times power over
conventional cage wheel.
The designed cage wheel was performed well in both road
and field. Reversibility without bogging down with flat lugs was
the most important characteristic obtained. This was the first
step in this swinging lug concept, and there are number of ways
to develop this wheel furthermore using the same retracting
principle . |
