Track belt guide wheels assembly

Abstract

A track assembly comprising guide wheels in a region of greatest impacts on the guide rails of the track, which are also the regions of greater wearout of the guide rails, the guide wheels being further arranged in a staggered position, thereby yielding a reduction in noise generation.

1 . An endless track belt assembly comprising an endless elongated body going around a sprocket wheel and a front wheel, and having a ground-engaging outer surface and an inner surface, the inner surface receiving, on a lower run thereof, a suspension comprising a plurality of guide wheels and guide rails, 
 wherein said plurality of guide wheels comprises guide wheels positioned transversally in ones of aligned pairs and staggered pairs in a forward region of the assembly, one of said pairs being located close to a curved region of the forward region of the assembly.    
   
   
       2 . The endless track belt assembly as recited in  claim 1 , wherein the guide wheels are positioned transversally in staggered pairs in the forward region of the assembly, each guide wheel of a given pair being in a staggered position with respect to a counterpart thereof.  
   
   
       3 . The endless track belt assembly as recited in  claim 2 , wherein a pair of guide wheels close to a point of attachment of the assembly is in a staggered position.  
   
   
       4 . The endless track belt assembly as recited in  claim 1 , wherein the ground-engaging surface bears a series of spaced profiles.  
   
   
       5 . The endless track belt assembly as recited in  claim 4 , wherein clips are provided on the profiles.  
   
   
       6 . The endless track belt assembly as recited in  claim 4 , wherein the endless belt is provided with aperture in between the profiles.
