Tire antiskid chain production method and application thereof

Abstract

The invention relates to the field of tire skid resistance, and particularly discloses a tire antiskid chain production method and application thereof, and the method comprises the following steps: punching holes in at least two braids at equal intervals; mounting a nail catcher in each through hole; the braids provided with the sewing buttons are sewn and fixed to annular cloth with elastic closing openings in the two sides in a parallel and spaced mode, and therefore the antiskid chain body is manufactured. The antiskid chain produced by the method is structurally characterized by comprising the annular cloth with the elastic closing opening and parallel braids which are fixed on the inner side of the annular cloth and are provided with sewing buttons. By combining the button sewing braid and the elastic annular cloth, the problems that an existing flexible antiskid chain is insufficient in axial constraint of the tire and prone to transverse slippage or falling off are effectively solved; the elastic closing-up openings on the two sides of the annular cloth can generate continuous radial holding force after installation, it is ensured that the antiskid chain is tightly attached to the side wall of the tire, and meanwhile it is ensured that the sewing buttons exposed to the tread provide reliable antiskid performance.

Description

Technical Field

[0001] This invention belongs to the field of tire anti-skid, specifically a method for producing tire anti-skid chains and its application. Background Technology

[0002] Tire chains are essential equipment used to provide extra grip to vehicle tires on low-traction surfaces such as ice, snow, and mud, ensuring driving safety. Their basic principle is to add raised structures with a higher coefficient of friction or that can embed themselves in the road surface to the tire tread, allowing it to penetrate layers of ice and snow and directly contact the solid road surface below.

[0003] Traditional snow chains are mainly divided into metal chain types and flexible snow chains, which have emerged in recent years. Metal chain snow chains consist of metal chains connected in a crisscross pattern to form a net. While sturdy, durable, and with excellent anti-skid effect, they generally suffer from drawbacks such as heavy weight, cumbersome installation, loud driving noise, and potential damage to tires and road surfaces. To address these issues, flexible snow chains have been developed. They typically use rubber, polymers, or fabric as the base material and embed or connect anti-skid studs and anti-slip blocks. These products are lighter, cause less damage to tires and road surfaces, and offer improved driving smoothness.

[0004] However, existing flexible snow chains still have significant shortcomings in design and use. A common flaw lies in their fixing and bonding methods: many products rely primarily on hooks, buckles, or tensioning bands at their ends to tighten and secure them in the tire's circumferential direction, but lack an effective restraint mechanism in the tire's axial direction (i.e., the width direction). In actual driving, especially when turning or subjected to lateral forces, snow chains are prone to lateral slippage on the tire tread or even completely detaching, resulting in loss of anti-skid effect and potentially causing safety hazards. Furthermore, how to efficiently, firmly, and uniformly integrate anti-skid units (such as buckles) onto a flexible substrate while ensuring the overall product's durability and ease of installation remains a problem that needs to be optimized in existing technologies. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a method for producing tire anti-skid chains, thereby resolving the issue of complex structures in existing flexible anti-skid chains that combine low noise and high reliability.

[0006] This invention provides a method for producing tire anti-skid chains, comprising the following steps:

[0007] S1. Punch holes at equal intervals on at least two webbing strips to form multiple through holes;

[0008] S2. Install a fastener on each of the through holes of the webbing;

[0009] S3. The pair of webbings with the buckles installed are sewn and fixed in parallel and spaced manner onto a ring-shaped fabric with elastic openings on both sides to obtain the anti-skid chain body.

[0010] Preferably, in step S1, the spacing of the equally spaced holes is set according to the specifications of the target tire and the required distribution density of the anti-skid studs.

[0011] Preferably, in step S2, the fastener is a metal anti-slip fastener, an engineering plastic fastener, or a vulcanized rubber fastener, and is fixed to the through hole by riveting, screwing, or interference fit.

[0012] Preferably, in step S3, the sewing and fixing are done with nylon thread; the elastic ends on both sides of the annular fabric are made of elastic bands, elastic yarns or elastic fibers that are sewn or woven in.

[0013] Preferably, the unstitched area of ​​the annular fabric is further provided with a texture or coating to increase the static friction between it and the tire tread.

[0014] A tire anti-skid chain produced by the above method includes:

[0015] A ring-shaped piece of fabric with elasticated ends on both sides;

[0016] At least two parallel and spaced webbing strips are sewn and fixed to the inside of the annular fabric;

[0017] Multiple fasteners are installed at equal intervals on each of the webbing, and the fasteners are installed in such a way that their tips face away from the inside of the annular fabric.

[0018] Preferably, the material of the annular fabric is Oxford cloth, nylon cloth, or rubber composite fabric.

[0019] Preferably, the webbing is nylon webbing, polyester webbing, or aramid webbing.

[0020] Preferably, the circumference of the annular fabric is smaller than the static circumference of the target tire under standard air pressure, and a clamping force is generated through the elastic openings on both sides.

[0021] In one application of the tire anti-skid chain as described above, the anti-skid chain is slipped onto the side of the tire, so that the annular fabric is tightly bound to both sides of the tire through elastic closures on both sides, and the buckles are exposed on the tire's contact surface for anti-skid purposes.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] By combining webbing with snap fasteners with looped fabric with elastic cuffs on both sides, the production process of anti-skid chains has been optimized and the product performance has been significantly improved. This method not only simplifies the production steps, but also ensures that the snap fasteners are firmly and accurately distributed on the webbing.

[0024] The anti-skid chain product made by this method has elastic closures on both sides of the ring-shaped fabric, which can be easily slipped on from the side of the tire during use. Relying on the continuous radial clamping force generated by the elastic closures, it automatically adapts to and fits tightly to the sidewalls of tires of different sizes, effectively preventing lateral slippage and detachment during driving.

[0025] Meanwhile, the exposed studs on the tire tread provide reliable ground contact and anti-skid capability, achieving an effective balance between ease of installation, stability in use, and tire adaptability. Attached Figure Description

[0047] Example 3 (Applicable to light trucks)

[0048] This embodiment demonstrates the application of the solution in a larger load scenario, while the core features and specified materials remain unchanged.

[0049] 1. Production method:

[0050] S1. Select a 35mm wide reinforced nylon webbing 3 and punch holes with a center-to-center distance of 40mm.

[0051] S2. According to the specifications of the light truck tire (e.g., specification 215 / 75 R16 LT), cut two 650mm long webbing segments and use heavy-duty riveting equipment to firmly rivet and fix the thickened galvanized carbon steel metal buckles 4.

[0052] S3. Use thickened polyester fabric to sew a ring-shaped fabric 1 with a circumference of 2250mm. Strongly sew a 20mm wide high-elastic flat elastic band 2 to both sides of the ring-shaped fabric 1; finally, sew the two webbing strips to the outer surface of the ring-shaped fabric 1 with the buttons facing outwards and parallel (center distance 120mm).

[0053] 2. Product Structure:

[0054] The product consists of a thickened polyester ring fabric 1, double-sided high-elastic flat elastic bands 2, two 650mm long nylon webbing straps 3 fixed on the outside, and galvanized carbon steel metal buckles 4 distributed at 40mm intervals.

[0055] Example 4: A method for producing tire anti-skid chains, comprising the following steps:

[0056] S1. Take two aramid webbing strips, each 20mm wide, and cut them to the appropriate length according to the ground contact length of the target tire (such as a small car tire). Use precision equipment to laser-drill holes at equal intervals of 25mm on each webbing strip to form through holes.

[0057] S2. Use anti-slip studs made of engineering plastics (such as polyamide) as the studs; the bottom of the stud is designed with a threaded rod; pass the threaded rod through the through hole from the inside of the webbing, and screw on the matching nylon anti-loosening nut on the outside of the webbing to securely lock the stud to the webbing by screwing, with the tip facing outward after installation.

[0058] S3. Use lightweight and abrasion-resistant nylon fabric to make a ring-shaped fabric with a suitable circumference, and weave elastic yarn into both sides of the ring to form a built-in elastic closure; finally, sew the two webbing straps with engineering plastic fasteners on them to the inside of the ring-shaped fabric with nylon thread in a parallel and spaced manner.

[0059] The anti-skid chain produced in this embodiment has buckles made of engineering plastic, which are fixed in a detachable or replaceable manner by screwing. It is suitable for scenarios where weight is sensitive or where it is necessary to avoid scratching the wheel hub with metal. The elastic end is made of woven elastic yarn, which makes the appearance simpler.

[0060] Example 5: A method for producing tire anti-skid chains, comprising the following steps:

[0061] S1. Punch holes smaller than the diameter of the fastener rod at equal intervals on two polyester webbing strips.

[0062] S2. Vulcanized rubber buckles are selected, and the barb structure is designed on the barb part. Using a special pressing tool, the rubber buckle is forcibly pressed into the hole of the webbing. The elastic deformation of the rubber and the barb structure create an interference fit with the hole wall, thereby achieving a firm fixation.

[0063] S3. A ring-shaped fabric is made using rubber composite fabric, and wide elastic bands are sewn into both sides to form an elastic closure; a high-friction coefficient rubber coating is applied to the inside of the ring-shaped fabric corresponding to the non-stitched area of ​​the tire tread using a spraying process to significantly increase the static friction between it and the tire tread; then, the webbing is sewn and fixed to the inside of the fabric.

[0064] Product and Features:

[0065] The anti-skid chain's buckles are made of flexible vulcanized rubber and are fixed with an interference fit, providing effective grip on ice while being more ground-friendly. The coating on the inside of the circular fabric ensures that the anti-skid chain does not slip relative to the tire, improving reliability.
