Track assembly

A vehicle track assembly, comprising:

• an adjustable main frame supported for tilting movement on an axis transverse to said main frame;
• said main frame having spaced apart first and second ends separated by a body extending therebetween;
• said main frame having a topside and an underside in spaced apart relation with opposed sidewalls extending therebetween;
• said main frame first end equipped with a tensioning bracket;
• said tensioning bracket equipped with a first axle tube;
• said first axle tube oriented transverse to said main frame to accommodate a first axle with a first set of end wheels in spaced apart relation to each other;
• said end wheels for rotation on parallel transverse axes;
• said tensioning bracket adjustable longitudinally on said main frame;
• said main frame second end equipped with a pivotal alignment bracket;
• said pivotal alignment bracket equipped with a second axle tube oriented transverse to said main frame to accommodate a second axle with a second set of end wheels in spaced apart relation to each other;
• said second set of end wheels for rotation on parallel transverse axes;
• said body portion of said main frame equipped with a reinforcing bracket assembly pivotally attached on said main frame top side intermediate said main frame first end and said main frame second end;
• said reinforcing bracket equipped with an implement axle tube oriented transverse to said mainframe for pivotal movement relative to said mainframe;
• said implement axle tube adapted to receive an implement axle shaft secured to a vehicle frame;
• said implement axle shaft to carry an implement wheel
• a flexible endless belt extending around the first and second set of end wheels, as well as the reinforcing bracket assembly and having an upper run and a lower run for engaging a travel surface;
• a plurality of bogie wheels each having a transverse axis and each engaging the lower run of the endless belt;
• said bogie wheels attached to roller beams isolated from said main frame;
• said bogie wheels including a forward set of four bogie wheels on a first roller beam and a rearward set of four bogie wheels on a second roller beam;
• said bogie wheels supported below said main frame in suspended floating relation;
• said floating relation including vertical float and pitch, roll and yaw compliance;
• each set of bogie wheels supported for independent vertical and tilting movement relative said main frame.
