CN2130141Y - Anti-slip tyre - Google Patents

Abstract

The utility model relates to an anti-slip tyre, which comprises the inner opening of the tyre, a tyre body, surface pattern blocks, a surface crisscross groove and side patterns. The surface pattern blocks are distributed weftwise, and the two side walls of the patterns are sloped in a same direction which is opposite with the direction of the rotation of the tyre. The two adjacent patterns arranged front and back are jointed on the bottom, and outward opened forming a V-shaped groove, but the two sides of the V-shaped groove are different. Two vertical ring-shaped groves are arranged on the tyre surface, and the transverse patterns are divided into 3 staggered portions. The anti-slip tyre can increase the frictional resistance between the tyre and the road when braking, can increase the driving stability, and can be widely used on various motor vehicles, with the advantage of long service life.

Description

Anti-slip tyre

The utility model relates to a kind of vehicular traffic nonskid tire

Now the conventional tyre of using mainly contains two kinds of cros-rib tread and circumferential patterns.The tire longitudinal frictional force of circumferential pattern is little, and braking effect is poor; The tire side-friction of cros-rib tread is little, and impact is big, and sound is big, and about one-third of the area does not have any decorative pattern in the middle of most surface.Do not have the position of decorative pattern only to play bearing force and the floating effect of putting forth effort, its friction drag is very low.Leave dead slot between two pattern blocks, during brake, the front portion of each pattern block is subjected to pavement friction to produce resistance, move backward, move at the rear portion then dead slot place between pattern block, elongates to become short, deliquescing, reduced and the ground-surface friction drag, reduced braking effect.Because of the anterior friction force of decorative pattern is big, abrasion is fast, and the rear portion friction force is little, and abrasion is slow, and after use a period of time, whole decorative pattern has become shape of a hoof decorative pattern.So not only reduced friction drag, increased the rate of skidding, and tire is short service life.

The purpose of this utility model is the shortcoming that overcomes above-mentioned prior art, and a kind of novel tire is provided, and it can prevent from length and breadth to reduce impact and sound to skidding, and increase the stationarity of travelling, and braking effect is good, long service life.

The purpose of this utility model is achieved through the following technical solutions: this tire is made up of tire internal orifice, tire body, surface detail piece, surperficial vertical-horizontal slot and ray flower line, the pattern block of surface of tyre becomes transverse distribution and decorative pattern two side all to tilt to a direction, and direction of tilt is opposite with the direction of tyre rotation.Intersect two adjacent pattern blocks bottoms of front and back, outwards opens and constitute the bevelled vee shape groove that does not wait on both sides, during brake, tire stops operating and to front slide, the front portion of each pattern block and pavement friction produce resistance and move backward, and the pattern block rear portion is supported because of constant slope is arranged, and moves motionless backward, utilize the effect of the gradient strong point, make the high hardening of pattern block integral body degree, increased friction drag, and make carcass stressed evenly for the road surface, the decorative pattern wear resistance is strong, has prolonged service life.Another feature is that surface of tyre has two vertical annular ditch grooves, and with decorative pattern five equilibrium three parts of transverse distribution, and this three parts decorative pattern is staggered.During tire rolling, the centre portion decorative pattern is the contact road surface earlier, contacts the road surface behind the decorative pattern on both sides, has so just reduced impact and sound, has increased the stationarity of vehicle '.And two vertical annular grooves of surface of tyre have remedied the little deficiency of tire side-friction of cros-rib tread, can prevent from laterally to skid.

The utility model compared with prior art has following advantage: tire all strengthens to friction force in length and breadth, has solved that vehicular traffic travels, the problem of skidding when braking; The impact of tire and sound when having reduced vehicle ' increase the stationarity of travelling; Carcass is stressed evenly, and the decorative pattern wearing and tearing are slow, long service life.

Accompanying drawing 1 is a block diagram of the present utility model, and accompanying drawing 2 is its localized axial views.Wherein 1 is the tire internal orifice, the 2nd, and tire body, the 3rd, tire tread block, the 4th, the surface longitudinal annular ditch groove, the 5th, the ray flower line, the 6th, the pattern block front side wall, the 7th, the pattern block rear wall, the 8th, surperficial lateral trench, α are the pattern block anterior angles, β is the pattern block relief angle.

Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated: surface of tyre lateral trench (8) wide about 5-30mm suitable for reading.Decorative pattern anterior angle α is meant the angle of inclination of decorative pattern front side wall (6), is 5-25 °, and decorative pattern relief angle β is meant the angle of inclination of decorative pattern rear wall (7), is 20-65 °.If surperficial lateral trench (8) width suitable for reading is excessive, the skin area of tire tread block (3) is little, and tire and road surface contact surface are just little, and pattern block (3) easily is elongated and becomes short, deliquescing, and is just little with the ground-surface friction force, and the easy breach in groove (8) bottom; If surperficial lateral trench (8) width suitable for reading is too small, holding power is just little, and is also just little with the ground-surface friction force.The decorative pattern anterior angle is 5-25 °, relief angle is 20-65 °, pattern block (3) front portion was uprightly uprised by friction drag when anterior angle, relief angle only just can make brake in above-mentioned scope, and because of the effect of the gradient strong point, pattern block (3) slippage backward, its rear portion also uprightly uprises, and make whole pattern block uprise hardening, decorative pattern front side wall (6) and decorative pattern rear wall (7) all approach plumbness, have increased pressure intensity for the road surface, the friction drag when having increased brake.If the angle of inclination of decorative pattern front side wall (6) and decorative pattern rear wall (7) is excessive or too small, during brake also out of reach sidewall all approaches plumbness before and after the decorative pattern because of the road surface friction force effect makes, and make the height hardness of whole pattern block (3) not enough, thereby the tire friction drag is reduced.This tire can adopt the reinforcement of arc reinforcement glue in groove intersection during fabrication.When this tire is used on the lorry, can suitably increase the wide cut at tire top, increase tire and ground-surface area of contact, when brake, increase friction drag.This tire applications should increase the transverse groove line at its pattern block middle part when C-class, its degree of depth is half of original surface groove.So just can soften the decorative pattern top layer, make the tyre surface softness, stressed even, increase friction drag, and can avoid the groove stress raisers breach to occur.
