Abstract
The invention relate to a tyre with a stone ejector that can prevent stones from being embedded into tread groove on grounding surface. The tyre provides a stone ejector with a protrusion that formed facing external upwards on two sides of bottom of the tread groove, and when a grounding part is compressed when contacting with ground, the protrusion facing external upwards prolapses inwards; when the compression of the grounding part is removed, the protrusion prolapsing inwards resume back to initial position, and the protrusion exerts a pressing force o external side of the tread groove, which can effectively discharge stone embedded into the tread groove.
Description
Technical field
The present invention relates to automobile tyre, particularly relate to a kind of possess prevent that stone from nipping and be formed on the tire of the stone portion of picking (stone ejector) in the groove on the ground plane.
Background technology
Be formed with various grooves on the ground plane of tire, particularly wait at the construction field (site) under the situation of the lorry tire that travels, have the situation of the stone of nipping in the groove.Enter the stone in the groove, can be deep under steam in the groove and the wearing and tearing groove, therefore make stress cause separating of bracing ply and tyre surface to the bracing ply that is positioned at the groove below.
Therefore, also once provided a kind of on groove, the setting pick stone portion and tire that the stone of the groove of will nipping is easily discharged in the past.
Provide following tire in the Korean Patent 10-0592991 communique (publication number 10-0049220), that is: be formed with the stone portion of picking of overshooting shape in the groove lower end, and the upper face that picks stone portion of overshooting shape is formed recess forming recess, and the caoutchouc elasticity of the fence by forming the recess edge is discharged the tire of stone.Yet in such tire, the caoutchouc elasticity of the fence that desire will be by recess is discharged stone, but in fact has more weak and its effect and insufficient of the elastic force of fence, and because of the fence that makes thinner thickness with contacting of stone easily from the shortcoming of projection disengaging.
In addition, provide following lorry tire in the Korean Patent Publication No. 2004-0043976 communique, that is: be formed with protrusion on the sidewall of groove with two radiuss of curvature, and be formed with protrusion on another sidewall opposed with it, this protrusion is with respect to the point on the line of centers of above-mentioned groove and symmetrical with the protrusion of an above-mentioned sidewall.Yet the main purpose of considering groove is draining, and the shared volume of the stone portion of picking in the groove is excessive among the present invention.In other words, there is the more weak shortcoming of drainage in such stone portion of picking.In addition, be positioned at picking stone portion and arrive the bottom of groove on the two side, then exist to be difficult to bite into the shortcoming that the stone in the groove is discharged if the less stone of diameter bites into.
Summary of the invention
So, the objective of the invention is to, provide a kind of and have the volume reduction that not only reduces groove, and discharge the tire that picks stone portion that bites into the stone in the groove effectively.
In order to solve above-mentioned purpose, the invention provides a kind of both sides and possess the tire that picks stone portion in groove bottom, this picks stone portion and is formed by the projection on the direction outward.
Description of drawings
Fig. 1 is the cutaway view of expression part of the present invention.
Fig. 2 be because of the ground pressure tire that contacts with ground be subjected to earth contact pressure grounding parts is expanded and make the sagging state of projection and from projection sagging begin to be disengaged to earth contact pressure grounding parts restPosed and make projection be in the instruction diagram of initial condition towards the top.
The specific embodiment
Tire of the present invention, constitute by tyre surface, sidewall and tyre bead, and on tyre surface, be formed with groove, and on groove 1, be formed with the stone portion of picking, it is characterized in that, pick stone portion and constitute, and have sagging resettlement section 31, so that projection 3 is pushed sagging by the grounding parts that expands because of ground connection power at the medial surface of projection 3 by the projection 3 that is arranged on 2 both sides, groove bottom.
Preferably, sagging resettlement section 31 is formed by flat wall, but can certainly be formed by the sagging curved face part of the front end that can make projection 3.Below, the embodiment under the situation that the sagging resettlement section 31 of explanation is formed by flat horizontal surface.
Preferably, sagging resettlement section 31 has with travel direction line L and is 75~100 ° angle B.In addition, more preferably, sagging resettlement section 31 has with travel direction line L and is 90~75 ° angle B.Above-mentioned angle in sagging resettlement section 31 forms under the situation of the acute angle below 75 °, and the intensity of projection 3 front ends is more weak and be difficult to tire is extracted from sulfurizing mould.
But the above-mentioned angle of sagging resettlement section 31 also can form more than 90 ° 100 ° obtuse angle.In these cases, the sag of chain of projection 3 reduces and the polynary distance minimizing of projection 3, but discharges the power grow of stone but opposite recuperability becomes big.
Possess by the tire of the present invention of the stone portion of picking that forms of the projection on the direction outward from the both sides of groove bottom, when grounding parts contacts with ground and is compressed, projection on the direction is inwardly sagging outward, when the compression of grounding parts is disengaged, inwardly sagging projection upwards returns to initial position, and projection applies the power of pushing towards the outside of groove, can discharge the stone that bites into groove effectively.
In addition, the present invention has following effect, promptly, when grounding parts contacts with ground and is compressed, projection on the direction is inwardly sagging outward, the stone portion of picking through tire of playing when making ground connection arrives the effect that the size of the path of groove bottom reduces, and has to prevent that stone from biting into the effect of groove bottom phenomenon.
Claims (3)
1. an automobile tyre is made of tyre surface, sidewall and tyre bead, is formed with groove on tyre surface, has the stone of picking portion in the bottom of above-mentioned groove, it is characterized in that:
Above-mentioned pick stone portion by both sides, above-mentioned groove bottom towards above projection constitute, and have sagging resettlement section at the medial surface of above-mentioned projection, this sagging resettlement section forms by having the flat wall that is 75~100 ° angle with travel direction line (L).
2. automobile tyre according to claim 1 is characterized in that: above-mentioned sagging resettlement section has with travel direction line (L) and is 90~75 ° angle.
3. automobile tyre according to claim 1 is characterized in that: above-mentioned sagging resettlement section has with travel direction line (L) and is 90~100 ° angle.
