ABSTRACT:
An improved radio-controlled track-driven vehicle comprises an innovative belt drive structure in which the rear wheels engage with the belt in positive drive, and the front wheels engage with the belt in frictional drive. According to one embodiment of the invention, the drive belt has taller central teeth that are received within a central groove of the front and rear wheels, and shorter lateral teeth that mesh with complementary toothed regions of the rear wheels and frictionally contact corresponding smooth cylindrical surfaces of the front driven wheels. In another embodiment of the invention, the belt teeth extend transversely across most of the width of the belt, with alternate teeth having disposed thereon a taller central tooth to be received within the wheel grooves.
