Abstract
The invention relates to a method for marking and reading deep abrasion of a tire pattern, which is characterized by comprising the following steps: directly molding vertical deep grooves on a tire crown through a mould while manufacturing a tire tread, wherein the vertical deep grooves are located on the surface of the tire pattern and a plurality of vertical deep grooves are molded; while molding the vertical deep grooves, displaying the outlines of the vertical deep grooves as X%, wherein a ratio of the depth of each vertical deep groove to the total depth of the tire pattern is 100%-X%, and the X% is the percentage at the vertical deep groove; and while checking the practical depth of the tire pattern, displaying one or more X% through the outlines of the vertical deep grooves, wherein the practical depth of the tire pattern exceeds the displayed maximal X%. According to the marking method provided by the invention, when the depth of the tire pattern is checked, the present depth of the tire pattern can be directly read out, no conversion is required, the check is convenient and accurate, the defect of fuzzy marking of the traditional method is overcome and no misreading phenomenon occurs.
Description
Technical field
The present invention relates to a kind of pattern depth wearing and tearing sign, read method, particularly a kind of clear display, accurately and pattern depth wearing and tearing sign, read method.
Background technology
When tread bar were too shallow, except draining was bad, the heat of crown can not in time be discharged, and the tire temperature is risen, and easily crown glue was consulted during emergency braking and caused blowing out; In addition, decorative pattern is too shallow, is punctured tyre surface by tip and hard object especially easily.The residual degree of depth of tread bar can not be lower than 1.6mm; No matter the propulsive effort or the deceleration and stopping performance that are tire all will reduce greatly, the tire that has polished decorative pattern is commonly called as Slicks, though fine at the dry pavement earth-grasping force; But " hydroplane " phenomenon can appear when running into the water route, and extremely dangerous.Here it is hydro-planing.Therefore, pattern depth wearing and tearing marking structure is particularly important to the safety of tire.
Present pattern depth mark adopts limit markers, and a label symbol is arranged on the sidewall of tire, in the crown that label symbol faced toward, is carved with the boss that exceeds the groove trench bottom a little under the decorative pattern, represents the residual depth limit of wearing and tearing of decorative pattern.Be that decorative pattern wearing and tearing back groove shoals.Will expose boss, when the decorative pattern height was the same with boss, expression groove groove depth also had 1.6mm, must changing of tire.Its shortcoming is: can only identify limit, can't know in the appropriate time and exchange, if the boss of a plurality of different depths is set, then can't accurately confirm the actual height of each boss again, occur the disconnected problem of erroneous judgement easily; If in the decorative pattern groove, be provided with and the cooresponding reading of boss height, then because the dimensional restriction of groove, the reading clear demonstration of also having no idea.
Summary of the invention
The technical matters that the present invention will solve provide a kind of clear display, accurately and pattern depth wearing and tearing sign, read method.
For solving the problems of the technologies described above; Technical scheme of the present invention is: a kind of pattern depth wearing and tearing sign, read method; Its innovative point is: when tire protector is made; Through the vertical deep trouth of mould straight forming on tyre crown, this vertical deep trouth is positioned at the surface of tire tread, and the quantity of vertical deep trouth has several; When the vertical deep trouth of moulding, the profile of vertical deep trouth is shown as a percentage registration X%, and the ratio of each vertical deep trouth and tire tread total depth is 100%-X%, and wherein X% is the percentage registration at this vertical deep trouth place; When checking the tire tread actual grade, show one or above percentage registration X% through vertical deep trouth profile, the tire tread actual grade surpasses the largest percentage reading X% that can show.
Further, said vertical deep trouth can be provided with three, and the profile of three vertical deep trouths is shown as 25%, 50%, 75% respectively; Degree of depth registration 25%, 50%, the 75% pairing vertical deep trouth degree of depth and tire tread total depth ratio are respectively 75%, 50%, 25%.
The invention has the advantages that: adopt identification method of the present invention; When needs are checked pattern depth; Directly check degree of depth registration; If the maximum registration that can read is promptly represented actual tire tread and also has this more than registration that for example tire tread face can see that the profile of vertical deep trouth shows 25%, 50%, 75%, then identifies this tire tread and also has more than 75%; Show 25% if only see profile, explain that actual pattern depth surpasses 25%, but be lower than 50%; When therefore carrying out tyre inspection; Just can utilize information to carry out handled such as the exchanging of tire, replacing, need not to convert, check conveniently, accurately; Avoid orthodox method to identify unsharp defective, misread phenomenon can not occur.

Fig. 1 is the tire tread birds-eye view of embodiment among the present invention.
Fig. 2 is along J-K line cutaway view among Fig. 1.
Fig. 3 for after the tire tread wearing and tearing along J-K line cutaway view.
The specific embodiment
When tire protector was made, through the vertical deep trouth of mould straight forming on tyre crown, this vertical deep trouth 2 was positioned at the surface of tire tread 1, and the quantity of vertical deep trouth 2 has several, can be referring to Fig. 1.
When the vertical deep trouth 2 of moulding, the profile of vertical deep trouth 2 is shown as a percentage registration X%, and each vertical deep trouth 2 is 100%-X% with the ratio of tire tread 1 total depth, and wherein X% is the percentage registration at this vertical deep trouth place.In the present embodiment, as shown in Figure 2, vertical deep trouth 2 is set to three, and the profile of three vertical deep trouths 2 is shown as 25%, 50%, 75% respectively; Degree of depth registration 25%, 50%, 75% pairing vertical deep trouth 2 degree of depth and tire tread 1 total depth ratio are respectively 75%, 50%, 25%.
When checking the tire tread actual grade; Show one or above percentage registration X% through vertical deep trouth 2 profiles; The tire tread actual grade surpasses the largest percentage reading X% that can show,, as shown in Figure 3; Can show that reading is 25% and 50%, then the actual grade of tire tread is more than 50% of the original degree of depth of tire tread.
