Track system for traction of an agricultural vehicle travelling on fields and roads

Abstract

A track system for an agricultural vehicle is configured to better perform when the vehicle is roading, including to reduce or minimize deteriorative effects on a track of the track system as the vehicle travels against a road's hard surface, especially at higher speeds.

         7 . A track for traction of a vehicle on a ground, the track being mountable around a track-engaging assembly including a plurality of track-contacting wheels configured to drive and guide the track around the track-engaging assembly, the track being elastomeric to flex around the track-engaging assembly, the track comprising:
 a ground-engaging outer surface and an inner surface opposite to the ground-engaging outer surface; and   a plurality of traction projections projecting from the ground-engaging outer surface, each traction projection being shaped to reduce potential for heat buildup within the traction projection.   
     
     
         8 . The track of  claim 7 , wherein: the traction projection comprises a top surface configured to face the ground; and a width of the top surface of the traction projection is greater than a height of the traction projection. 
     
     
         9 . The track of  claim 7 , wherein: the traction projection comprises a top surface configured to face the ground; and a ratio of a width of the top surface of the traction projection over a width of the track is at least 0.1. 
     
     
         10 . The track of  claim 7 , wherein: the traction projection comprises a top surface configured to face the ground; and a ratio of a width of the top surface of the traction projection over a width of the track is at least 0.2. 
     
     
         11 . The track of  claim 7 , wherein a ratio of a height of the traction projection over a thickness of the track from the ground-engaging outer surface to the inner surface is no more than 1.2. 
     
     
         12 . The track of  claim 7 , wherein a ratio of a height of the traction projection over a thickness of the track from the ground-engaging outer surface to the inner surface is no more than 1.1. 
     
     
         13 . The track of  claim 8 , wherein a ratio of the width of the top surface of the traction projection over the height of the traction projection is at least 1.2. 
     
     
         14 . The track of  claim 8 , wherein a ratio of the width of the top surface of the traction projection over the height of the traction projection is at least 1.6. 
     
     
         15 . The track of  claim 8 , wherein a ratio of the width of the top surface of the traction projection over the height of the traction projection is at least 2. 
     
     
         16 . A track for traction of a vehicle on a ground, the track being mountable around a track-engaging assembly including a plurality of track-contacting wheels configured to drive and guide the track around the track-engaging assembly, the track being elastomeric to flex around the track-engaging assembly, the track comprising:
 a ground-engaging outer surface and an inner surface opposite to the ground-engaging outer surface; and   a plurality of traction projections projecting from the ground-engaging outer surface, each traction projection comprising a top surface configured to face the ground, a width of the top surface of the traction projection being greater than a height of the traction projection.   
     
     
         17 . The track of  claim 16 , wherein a ratio of the width of the top surface of the traction projection over the height of the traction projection is at least 1.2. 
     
     
         18 . The track of  claim 16 , wherein a ratio of the width of the top surface of the traction projection over the height of the traction projection is at least 1.6. 
     
     
         19 . The track of claim X 9 , wherein a ratio of the width of the top surface of the traction projection over the height of the traction projection is at least 2. 
     
     
         20 . A track for traction of a vehicle on a ground, the track being mountable around a track-engaging assembly including a plurality of track-contacting wheels configured to drive and guide the track around the track-engaging assembly, the track being elastomeric to flex around the track-engaging assembly, the track comprising:
 a ground-engaging outer surface and an inner surface opposite to the ground-engaging outer surface; and   a plurality of traction projections projecting from the ground-engaging outer surface;   
       wherein a ratio of a height of each traction projection over a thickness of the track from the ground-engaging outer surface to the inner surface is no more than 1.2.
