Abstract

1367524 Endless tracks; anti-skid treadband for tyres CATERPILLAR TRACTOR CO 25 Nov 1971 [27 Nov 1970] 54826/71 Headings B7C and B7H [Also in Division B5] A flexible track belt 21 to be placed around the pneumatic tyres of, e.g. an earth working vehicle comprises support belts 35 (e.g. two as in Fig. 6 or four as in Fig. 2) to which are attached shoes 30 by means of keepers 33. The support belt 35 comprises layers W of fine, brass-plated steel filaments 50 encased in an elastomer E which is contained in channels 34 in the keeper 33 and highly compressed by the shoes 30 being tightened down by screws 32 or rivets (40) and belleville springs (44), Fig. 12 (not shown). The support belt may contain layers (F) of fabric, Fig. 10 (not shown). Attachment of the belt 35 to the tyre 22 is by collapsing the tyre, placing the track belt 21 around it and inflating the tyre. With larger tyres, the support belts 35 may be tensioned around the tyre by being clamped between shoes and keepers having arcuate mating surfaces (Fig. 14, not shown). Sufficient grip between the belt 21 and the tyre 22 may be afforded merely by a layer 70 of elastomer on the inside of shoes 30 or for improved lateral grip, lugs 46 on the inside of shoes 30 may co-operate with a groove in the tyre crown or the keeper 33 may be provided with a projecting leg (33a) which bears against the tyre sidewall (22), Fig. 7 (not shown). In the manufacture of the support belt (Fig. 11), a thin layer E of elastomer is first applied to the rim of a drivable drum 62 of appropriate diameter. Then a layer of wires 50 from a spool is helically wound on to the elastomer layer E by means of a bobbin 66, a further layer of elastomer is applied and so on. The wires 50 may be loosely twisted together. When winding is complete the elastomer of the belt is cured in an autoclave. A pneumatic tyre 80 (Fig. 15) suitable for receiving the track belt of the invention has an oval cross-section with an inextensible filament 81 helically wound around a torus-shaped elastomer liner 82 and covered by an elastomer casing 83. An internal bumper 85 to limit. deflection, an external centering rib 86 and antiroll hoops 87 may be provided. A track-laying vehicle may be provided with a track as in Fig. 6 but arranged to be placed around more than one wheel.
