Track assembly for tracked vehicles

A track assembly for a tracked vehicle comprising:

• a. a vehicle frame extending longitudinally of said vehicle;
• b. first and second track sprockets journaled at longitudinally-spaced positions on said frame so as to rotate about respective axes transverse to said frame;
• c. an endless track trained about said track sprockets;
• d. journaling means having said first track sprocket journaled therein, said journaling means being movably attached to said frame for permitting said first track sprocket to reciprocate in a longitudinal direction;
• e. an elastomeric bushing of resilient elastomeric material compressively interposed between said journaling means and said vehicle frame for permitting the movement of said first track sprocket longitudinally in a direction toward said second track sprocket while resisting said movement by a reactive compressive force of said elastomeric material variable in response to the degree of said longitudinal movement;
• f. said journaling means having a compression member extending therefrom toward said second sprocket, said compression member having first bushing engagement means mounted adjacent its extended end facing said second sprocket for engaging one side of said elastomeric bushing and threaded means for adjusting the longitudinal position of said first bushing engagement means on said extended end of said compression member, said vehicle frame having a mating bushing engagement means mounted thereon facing said first bushing engagement means for engaging the opposite side of said bushing, said elastomeric bushing being located between said two bushing engagement means.
