Abstract
A removable track belt for installation around the outer surface of a tire carcass has on its inner surface a plurality of circumferential lands and grooves that interlock with lands and grooves on the tire carcass. The inner surface of the track belt also has a plurality of spaced axial grooves for receiving removable rigid keeper bars, to which grousers are attached. The underside of each keeper bar contains lands and grooves that also mate with those of the tire carcass.
Claims23
A removable track belt assembly for installing about the circumferential surface of a tire carcass comprising:
- an annular belt matrix having a plurality of spaced axially oriented recesses in the inner circumferential surface thereof and further having a first pattern of raised and lowered portions, comprising at least one raised portion or one lowered portion, on the inner circumferential surface thereof to interlock with a complementary pattern of raised and lowered portions on the outer circumferential surface of the tire carcass to prevent relative movement of said belt matrix axially with respect to said carcass;
- a plurality of removable keeper bars positioned in said recesses, each of said keeper bars having an inner surface configured so as to be substantially in alignment with the inner circumferential surface of said belt matrix when said keeper bars are positioned in said recesses and further having a second pattern of raised and lowered portions, comprising at least one raised portion or one lowered portion, on the inner surface thereof to interlock with a complementary pattern of raised and lowered portions on the outer circumferential surface of the tire carcass to prevent relative movement of said keeper bars axially with respect to said carcass;
- and means attached to each of said keeper bars for supplying traction to said assembly.
A removable keeper bar for use with a removable tire track belt for installation upon the outer circumferential surface of a tire carcass, said track belt having an inner circumferential surface provided with a first pattern of raised and lowered portions, comprising at least one raised portion or one lowered portion, for engaging a complementary pattern on the outer circumferential surface of the tire carcass, said track belt having a plurality of recesses extending across the width thereof for receiving said keeper bars, each of said keeper bars comprising a center portion having an outer surface for seating in one of said recesses, an inner surface, and a second pattern of raised and lowered portions, comprising at least one raised portion or one lowered portion, on said inner surface engageable with a complementary pattern on the outer circumferential surface of said tire carcass.
