Endless track suspension

An endless track suspension comprising a suspension support beam having idler wheel assemblies connected to a respective one of opposed ends of said suspension support beam, at least one of said idler wheel assemblies having an endless track binding means, support wheels secured to said suspension support beam and projecting from a lower face of said suspension support beam, a drive sprocket secured above said suspension support beam by a support means, coupling means connectable to said drive sprocket for securing the drive sprocket to a vehicle drive axle;

• said drive sprocket, support wheels and idler wheel assemblies constituting an endless track support assembly for supporting an endless track in drivable engagement thereabout;
• and flexible suspension means comprising a torsion pivot connection between the suspension support beam and the support means, the torsion pivot connection permitting pivoting movement of the suspension support beam with respect to the support means, and comprising a flexible element limiting torsional displacement relating to said pivoting movement between the suspension support beam and the support means, the flexible element absorbing shocks and vibrations transmitted to said vehicle drive axle caused by the displacement of said endless track over a rough ground surface.
