Abstract
A track assembly for a land vehicle has idler wheels and road wheels that pivot about a common horizontal axis so the road wheels do not rub against the guide blocks of the belt when the land vehicle is transported over a crowned road. The elimination of rubbing decreases friction and heat and, thereby, increases the life of the belt.
Claims3
A track assembly comprising:
- a front idler double wheel having a diameter, the front idler double wheel having an inner wheel mounted on a pivoting spindle, an outer wheel mounted on the spindle, with a recess between the inner wheel and the outer wheel;
- a rear idler double wheel having a diameter, the rear idler double wheel having an inner wheel mounted on a pivoting spindle, an outer wheel mounted on the spindle, with a recess between the inner wheel and the outer wheel;
- a road double wheel between the front idler double wheel and the rear idler double wheel, the road double wheel having a diameter that is less than the diameter of the front idler double wheel and the diameter of the rear idler double wheel, the road double wheel having an inner wheel mounted on a pivoting spindle, an outer wheel mounted on the spindle, with a recess between the inner wheel and the outer wheel;
- a continuous belt having an inner surface with a continuous guide block or a plurality of discrete guide blocks, the belt extending around the front idler double wheel, the rear idler double wheel, and the road double wheel;
- and
- a frame in the recess between the inner wheels and the outer wheels of the front idler double wheel, the rear idler double wheel, and the road double wheel, the frame extending from the front idler double wheel to the rear idler double wheel;
- wherein the pivoting spindles of the front idler double wheel, the rear idler double wheel, and the road double wheel pivot about a common longitudinal axis.
