Track Assembly for an Off-Road Vehicle

Abstract

A track assembly for traction of an off-road vehicle, the track assembly comprising a set of wheels and an endless track disposed around the set of wheels. The endless track comprises elastomeric material to flex around the set of wheels. The endless track comprises a plurality of drive/guide lugs projecting inwardly. The set of wheels comprises a drive wheel for imparting motion to the endless track. The set of wheels may comprise a first plurality of roller wheels for rolling on a first rolling path of the inner side and a second plurality of roller wheels for rolling on a second rolling path of the inner side such that the drive/guide lugs are located between the first rolling path and the second rolling path, as well as a third plurality of roller wheels for rolling on top of the drive/guide lugs.

1 . A track assembly for traction of an off-road vehicle, the track assembly comprising a set of wheels and an endless track disposed around the set of wheels, the endless track comprising elastomeric material to flex around the set of wheels, the endless track comprising:
 i. an inner side facing the set of wheels, the inner side comprising a plurality of drive/guide lugs projecting inwardly; and   ii. a ground-engaging outer side for engaging the ground, the ground-engaging outer side comprising a plurality of traction lugs projecting outwardly;   wherein the set of wheels comprises:
 a drive wheel for imparting motion to the endless track; 
 a first plurality of roller wheels for rolling on a first rolling path of the inner side and a second plurality of roller wheels for rolling on a second rolling path of the inner side, the drive/guide lugs being located between the first rolling path and the second rolling path; and 
 a third plurality of roller wheels for rolling on top of the drive/guide lugs.
