This invention involves a filament wound composite core which is combined with one or more additional cores to produce a loop track characterized by transverse curvature and stud bands extending between the sandwiched or laminated cores and which extend to provide sprocket engagement for transferring motive power to the loop track, and a system for mounting the novel loop track on a vehicle.

1. A loop track adapted to provide motive support for vehicles comprising: at least two concentric composite cores, each of said cores being formed of filaments bound together by a suitable binder, a plurality of stud bands extending transversely of said cores, engagement means secured to the ends of each of said stud bands to receive sprocket teeth, and protective means connected to the ends of said stud bands providing a cover for and constituting a part of said engagement means. 2. A loop track adapted to provide motive support for a vehicle as claimed in claim 1 and which is normally circular in unstressed condition and which has a generally concavo-convex transverse cross section. 3. A loop track adapted to provide motive support for a vehicle as claimed in claim 2 and which includes an elastic strain isolating adhesive layer between said stud bands and said cores. 4. A loop track adapted to provide motive support for vehicles comprising: at least two concentric composite cores, each of said cores being formed of filaments bound together by a suitable binder, a plurality of stud bands extending transversely of said cores, engagement means secured to the ends of each of said stud bands to receive sprocket teeth, protective means connected to the ends of said stud bands providing a cover for and constituting a part of said engagement means, said loop track being generally concavo-convex in transverse cross section and normally circular in unstressed condition, a base frame located at least partially within the circumference of said cores, a drive sprocket journalled on said base frame and interconnecting with said engagement means, a first load roller journaled on said frame and exerting compressive pressure on the outer circumferential surface of said cores, a swing arm rotatably journaled on said base frame within said cores and having end walls extending beyond the periphery of said cores, a second load roller journaled between said end walls and exerting pressure against the outer periphery of said cores, an idler sprocket journaled within the periphery of said cores between said end walls and interconnecting with said engagement means, whereby the compressive pressure exerted on said cores by said load rollers, and the extensive forces exerted against the inner periphery of said cores by said drive wheels and said idler sprocket accommodate a flexible, generally elongated operational configuration of said cores. 5. A loop track adapted to provide motive support for vehicles as claimed in claim 4 and in which said swing arm is journaled onto said base frame through a rotatable shock absorber. 6. A loop track adapted to provide motive support for a vehicle comprising: at least two concentric, composite cores, each of said cores formed of filaments bound together by a binder and comprising a number of layers of continuous, circumferentially wound filaments, at least one layer of cross-filaments substantially enclosing and positioned at a biased angle relative to said circumferential fibers, at least one layer of circumferentially wound filaments extending around the outer periphery of said cross filaments, the inner diameter of the edges of each of said cores being less than the inner diameter of the central portion of said cores, thus to provide a barrel shape to said cores, a plurality of stud bands extending transversely of said cores, the ends of each of said stud bands terminating in a threaded portion having a thickened annular shoulder between said threads and the generally flat section extending between said cores, end caps comprising a central wall portion with two apertures therein, a protective cover flange extending outwardly from said central wall portion over the threaded ends of said stud bands, at least two legs extending inwardly from said central wall and defining a channel, the sandwich constituting a portion of each of said cores and adjacent pairs of stud bands inserted and contained respectively in said channels of each of said end caps, with the annular shoulders of adjacent stud bands inserted in the apertures in the central wall of said caps, a flexible tread secured to the outer peripheral surface of the outer core, inner link members inserted over the threads and positioned next to the annular shoulders and between stud bands of adjacent end caps, thus to constitute, in alternate conjunction with said central walls, the inner links of a chain providing spacing between said stud bands, a protective cap having end retainer shoulders threadably engaging the ends of said stud bands, and generally flat outer links journaled on said protective caps, providing connection between adjacent pairs of stud bands near their outer ends. 7. A loop track adapted to provide motive support for vehicles as claimed in claim 6 in which said cores are normally circular in unstressed condition, and which includes bearing rollers journaled on said protective caps between said inner and outer links.
