Title: Tyre with long life at high speed - has radially outermost reinforcement consisting of straight, e.g. polyamide, filaments with two stiffer, e.g. aramid, filaments wound round them
IPC: B60C9/00
Filed: 1991-10-29
Abstract: A tyre has a radial carcass anchored round the bead cores, radially outer belt layers, and a mechanically strong textile layer which is even further out radially, in which the high strength filaments run at an angle of max. 5deg to the circumference. This outermost layer consists of at least two types of filament which differ in Young's modulus; the stiffer filaments concerned take up not more than 10% of the tension when the textile material is extended to less than 20% of its limit; at extensions above 40% of the limit however they take up at least 60% of the tension stress, so that the textile material has a progressively steepening stress/strain curve. In this mechanically strong layer the core filaments are preferably polyamide or polyester and the filaments wound round it are preferably aramid. Pref. the yarn (6) of the mechanically strong radially outermost layer, has core filaments (7) which are spun polyamide fibres twisted into that form. When unstressed the core (7) is straight. Round it two Kevlar (R.T.M) filaments are wound helically (8, 9). These outer two (8, 9) are appreciably stiffer than the core (7) and do not shrink at the curing temp. The net result is that the stress/strain curve of the complete assembly is as steep as that of the two outer wound filaments (8, 9). ADVANTAGE - The tyre provides comfortable rides at low speeds whilst still retaining long life at max. speed and good road grip.
