Abstract:
A monitoring system alarms drivers of potentially dangerous road surface conditions such as water buildup or icing before it is perceptible to them reducing the possibility of an accident. The road surface friction (RSF) measurement analysis and alarm system monitors RFS utilizing either of two techniques: an extension of the vehicle's automatic braking system including those commonly referred to as the antilock braking system (ABS) to measure tire/wheel slip at constant velocity or accelerating; or an apparatus independent of ABS which rolls against the road surface to determine RSF condition. Both techniques analyze data and alarm or advise the driver of a potentially dangerous RSF condition.
Abstract:
A laminate composite structure is provided in continuous lengths or rolls for making an unvulcanized carcass for a radial ply pneumatic tire as an intermediate article of manufacture. The laminate has a ply and a plurality of elastomeric components hot formed and attached directly to the ply. Each component has a predetermined cross-sectional profile. The elastomeric components including, but not limited to, a liner, a sidewall, and a chafer. Additional other elastomeric components for the carcass can be formed and attached to the laminate structure. The laminate forms an intermediate article of manufacture that at a later stage of tire building can be cut to length and spliced along common ends to form a cylindrical carcass structure.
