Abstract
The utility model relates to a core-spun yarn asbestos-free clutch facing which can increase the bursting strength of the clutch facing, improve frictional coefficient stability and reduce abrasion rate. The core-spun yarn asbestos-free clutch facing comprises an asbestos-free clutch facing, wherein the core material of a framework of the asbestos-free clutch facing consists of glass fiber and copper wires, and is externally wrapped with a layer of composite fiber of cotton-shaped synthetic fiber and chopped glass fiber. The core-spun yarn asbestos-free clutch facing has the advantages of increasing the bursting strength of the clutch facing, improving frictional coefficient stability, reducing abrasion rate, and effectively preventing the defects of a product.
Description
Technical field
The utility model relates to a kind of composite yarn that can increase bursting strength, raising stable friction factor and the reduction wear rate of clutch surface does not have the asbestos clutch surface, belongs to auto-parts and makes the field.
Background technique
At present, the no asbestos clutch surface of selling on the market, on structural design, the skeleton frame core material of no asbestos clutch surface adopts two common straight Bo Weijia copper wires formation skeleton frame core material (seeing accompanying drawing 2), is aided with the slurry of Bond and frictional property regulator composition, form the clutch surface blank through twining braiding, provide hot pressing, heat treatment, mill to be processed into.Its deficiency: skeleton frame core material and slurry make the friction of clutch surface flake products, polishing machine instability in conjunction with bad, cause defectives such as shrinking big and product warpage easily.
Summary of the invention
Purpose of design: avoid the deficiency in the background technique, design a kind of composite yarn that can increase bursting strength, raising stable friction factor and the reduction wear rate of clutch surface and do not have the asbestos clutch surface.
Design proposal: in order to realize above-mentioned purpose of design, the utility model is on structural design, by changing the mode of framework material textural association, at the chemical fibre of skeleton frame core material coated outside one deck cotton shape and the composite fiber of chopped glass fiber, strengthen the roughness of framework material, make the adhesive strength between framework material and the slurry be greatly improved, increase the uniformity of distribution of material, thereby improve The comprehensive performance.
Technological scheme: composite yarn does not have the asbestos clutch surface, and it comprises no asbestos clutch surface, and the skeleton frame core material of described no asbestos clutch surface is made up of glass fibre and copper wire, the chemical fibre of coated outside one deck cotton shape and the composite fiber of chopped glass fiber.
The utility model is compared with background technique, increases bursting strength, the raising stable friction factor of clutch surface and reduces wear rate, effectively prevents the defective of product.
Description of drawings
Fig. 1 is the structural representation that composite yarn does not have skeleton frame core material in the asbestos clutch surface.
Fig. 2 is the structural representation of background technique.
Embodiment
Embodiment 1: with reference to accompanying drawing 1.A kind of composite yarn does not have the asbestos clutch surface, and it comprises no asbestos clutch surface, and the skeleton frame core material 1 of described no asbestos clutch surface is made up of glass fibre and copper wire, the chemical fibre of coated outside one deck cotton shape and the composite fiber of chopped glass fiber; The face of described composite fiber is a roughened surface.Its preparation process is a prior art, is not described herein at this.
What need understand is: though the foregoing description is to the utility model detailed text description of contrasting; but these text descriptions; just the simple text of the utility model mentality of designing is described; rather than to the restriction of model utility mentality of designing; any combination, increase or modification that does not exceed the utility model mentality of designing all falls in the protection domain of the present utility model.
Claims (2)
1. a composite yarn does not have the asbestos clutch surface, it comprises no asbestos clutch surface, it is characterized in that: the skeleton frame core material of described no asbestos clutch surface is made up of glass fibre and copper wire, the chemical fibre of coated outside one deck cotton shape and the composite fiber of chopped glass fiber.
2. composite yarn according to claim 1 does not have the asbestos clutch surface, it is characterized in that: the face of described composite fiber is a roughened surface.
