Abstract
This invention relates to an endless traction band that is used to propel tracked vehicles [i.e., vehicles which use endless traction bands rather than tires to contact the terrain over which they are driven, e.g., tractors, tanks, bulldozers, etc.] and, more particularly, to an improved traction band made from a polymer adapted to travel over a drive sprocket, a plurality of guide wheels and a tension wheel. The inner surface of the endless traction band comprises a different lug configuration which allows for the endless traction band to be installed more efficiently on a tracked vehicle.
Claims (8)
1. A traction band for use over a plurality of wheels of a tracked vehicle allowing such vehicle to travel on a ground surface, comprising:
an inner surface which faces said plurality of wheels and an outer surface which faces said ground surface;
said inner surface comprising an inward area, a central area and an outward area;
a first series of lugs, having a first height and which are disposed in rows in said inward area, along the longitudinal direction of said traction band;
a second series of lugs, having a second height higher than the first height and which are disposed in rows in said outward area, along the longitudinal direction of said traction band.
an inner surface which faces said plurality of wheels and an outer surface which faces said ground surface;
said inner surface comprising an inward area, a central area and an outward area;
a first series of lugs, having a first height and which are disposed in rows in said inward area, along the longitudinal direction of said traction band;
a second series of lugs, having a second height higher than the first height and which are disposed in rows in said outward area, along the longitudinal direction of said traction band.
2. A traction band as claimed in claim 1, wherein the said first height is smaller than said second and third height.
3. A traction band as claimed in claim 1, wherein the said first height is zero for a predetermined number of successive said first lugs.
4. A traction band as claimed in claim 1, wherein the traction band is endless.
5. A traction band as claimed in claim 1, wherein a third series of lugs are disposed on the said central area and along the longitudinal direction of said traction band.
6. A traction band as claimed in claim 5, wherein the said first series of lugs and the said second series of lugs are guide lugs and the said third series of lugs are drive lugs.
7. A traction band as claimed in claim 5, wherein the said first series of lugs and the said second series of lugs are drive lugs and the said third series of lugs are guide lugs.
8. An endless traction band for use over a plurality of wheels of a tracked vehicle allowing such vehicle to travel on a ground surface, comprising:
an inner surface which faces said plurality of wheels and an outer surface which faces said ground surface;
said inner surface comprising an inward area, a central area and an outward area;
a first series of lugs, having a first height and which are disposed in rows in said inward area, along the longitudinal direction of said traction band;
a second series of lugs, having a second height and which are disposed in rows in said outward area, along the longitudinal direction of said traction band;
a third series of lugs, having a third height and which are disposed in rows in said central area, along the longitudinal direction of said traction band;
wherein said first height is smaller than said second and third height.
an inner surface which faces said plurality of wheels and an outer surface which faces said ground surface;
said inner surface comprising an inward area, a central area and an outward area;
a first series of lugs, having a first height and which are disposed in rows in said inward area, along the longitudinal direction of said traction band;
a second series of lugs, having a second height and which are disposed in rows in said outward area, along the longitudinal direction of said traction band;
a third series of lugs, having a third height and which are disposed in rows in said central area, along the longitudinal direction of said traction band;
wherein said first height is smaller than said second and third height.
