AI Technical Summary

Problems solved by technology

The glass cord loses strength very quickly due to bending changes at small pulleys, ie generally at wheels with a diameter of less than 60 mm, which can lead to belt damage under high loads

Embodiment Construction

[0020] To illustrate the design according to the invention, figure 1 A schematic diagram of the ribbed belt 1 is shown in perspective section. Here the substructure 2 , the covering layer 3 , and the reinforcement carrier 4 , which are designed as glass fiber cords with a glass denier of 650 tex, can be clearly seen. The ribbed profile designed in this substructure has a coating 5 of a polyamide-cotton-elastane hook fabric comprising 50% by weight of polyamide 66. The coefficient of friction of such a belt is here between 1.2 and 1.9 according to the SAE J2432 standard.

Abstract

V-ribbed belt having a main body made of an elastomeric material, wherein the V-ribbed belt has a cover layer forming the back of the belt, a force-transmission zone with a plurality of tensile members forming reinforcements, and a substructure, which is provided with a V-ribbed profile, characterized in that the V-ribbed belt, as reinforcement, contains glass-fibre cords with a glass fibre count of between 320 and 1050 tex.

Description

technical field [0001] The invention relates to a V-ribbed belt with a base body made of an elastomer material, wherein the V-ribbed belt has: a cover layer as the back of the belt, a belt with tensile strands as a reinforcing carrier The force transmission area, and the substructure with poly-ribbed profiles. Background technique [0002] Ribbed belts (KRR) are used as drive belts primarily in vehicles to drive auxiliary components (auxiliary drive), for example for cooling water pumps, compressors or three-phase generators. Modern automotive motors are equipped with belt-starter-generator systems, which require extremely robust ribbed belts (KRR) in the drive of the auxiliary components. The components of such a system consist of poly-V-belts, starter-generators with power electronics and special tensioning systems that provide the correct belt for the starting process and for the operation of auxiliary components pre-tensioned. With these systems, the motor is no longe...
