Abstract
Abstract An endless traction belt for vehicles having at least two endless bands laterally spaced, the bands being transversely interconnected by grouser bars attached to the outer surface of the bands. The grouser bars are longitudinally spaced on the bands with the region laterally intermediate the bands adapted to be contacted by driving-sprocket teeth. Transverse lugs of elastomeric material are formed on the outer periphery of the bands to a greater height than the grouser bars and the lugs are disposed closely adjacent opposite sides of each grouser bar such that the grouser bars are recessed between and supported by the lugs to prevent shearing of the grouser attaching means.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
245 words
An endless traction belt of reinforced elastomer for sprocket-driven tracked vehicles characterized in that the said belt has: a. a plurality of endless flexible track bands disposed so as to orbit in axially spaced parallel arrangement; b. a plurality of elongated grouser bars of rigid material mounted transversely on the outer periphery of said bands in longitudinally spaced parallel arrangement with each bar interconnecting transversely all of said bands and with the portions of each bar intermediate said track bands being adapted to contact the teeth of at least one driving sprocket; c. a plurality of transverse lugs formed integrally on the outer periphery of each of said bands and extending outwardly therefrom an amount greater than the height of said grouser bars with one of said lugs disposed closely adjacent respectively opposite sides of each of said grouser bars, the transverse lugs between each pair of grouser bars being spaced from each other in a direction longitudinally of said belt; and, d. a plurality of longitudinal lugs extending outwardly from the outer periphery of each of said bands with one of said longitudinal lugs disposed longitudinally intermediate each two of said adjacent grouser bars and with each of said longitudinal lugs extending longitudinally of said track band integral therewith and with the said transverse lugs adjacent each of said grouser bars, the transverse width of each of said longitudinal lugs being substantially less than the width of the band on which it is located.
Claim 2
Dependent Claim
245 words
An endless traction belt of reinforced elastomer for sprocket-driven tracked vehicles characterized in that the said belt has: a. a plurality of endless flexible track bands disposed so as to orbit in axially spaced parallel arrangement; b. a plurality of elongated grouser bars of rigid material mounted transversely on the outer periphery of said bands in longitudinally spaced parallel arrangement with each bar interconnecting transversely all of said bands and with the portions of each bar intermediate said track bands being adapted to contact the teeth of at least one driving sprocket; c. a plurality of transverse lugs formed integrally on the outer periphery of each of said bands and extending outwardly therefrom an amount greater than the height of said grouser bars with one of said lugs disposed closely adjacent respectively opposite sides of each of said grouser bars, the transverse lugs between each pair of grouser bars being spaced from each other in a direction longitudinally of said belt; and, d. a plurality of longitudinal lugs extending outwardly from the outer periphery of each of said bands with one of said longitudinal lugs disposed longitudinally intermediate each two of said adjacent grouser bars and with each of said longitudinal lugs extending longitudinally of said track band integral therewith and with the said transverse lugs adjacent each of said grouser bars, the transverse width of each of said longitudinal lugs being substantially less than the width of the band on which it is located.
Claim 3
Dependent Claim
33 words
The traction belt defined in claim 1, further characterized in that each of said longitudinal lugs extends outwardly from the outer periphery of said band the same distance as said transverse lug portions.
