Abstract

The invention relates to a tire tread for stud insert, which applies the load to the stud inserted in the tire tread during the driving process, thus to improve the circumference of the stud inserting hole and accordingly prevent the shedding of the stud. Therefore, the stud (1) is inserted into the stud inserting hole (2) formed in the pattern block (3). The tire tread is characterized in that multiple buffering circular holes (4) are formed along the circumferential direction at certain intervals around the circumference of the inserting hole (2) of the stud (1).

Description

Be used for inserting the tyre surface of peg insert

Technical field

The present invention relates to a kind of tyre surface, it can insert for the peg that improves rideability on ice snow covered pavement.More particularly, the present invention relates to for the tyre surface that inserts peg, when it put on load on the peg that is inserted in the tyre surface under steam, the periphery of improvement peg patchhole was in order to prevent coming off of this peg.

Background technology

Now exploitation has various tires, and wherein, the tyre surface of tire is the rubber layer that directly contacts the road surface, be formed with continuous a plurality of grooves (groove) and pattern block on it, when the such pavement state of ice snow covered pavement travels, peg is inserted in the tyre surface, in order to improve the performance of travelling at ice and snow.

Usually, as shown in Figure 5, in the tyre surface 101 of the tire 100 that is inserted with peg 1, the inside of the pattern block 3 on the tyre surface 101 that is formed at this tire 100 cuts off otch (kerf), and certain space is set, bur outstanding post on it, make tire sclerosis, form the peg patchholes at the pattern block 3 of this tyre surface 10, insert in the hole at this peg and insert peg 1.

But, in the past, when peg 1 is inserted inserting in the hole of tyre surface 101, shown in Fig. 6 (A) like that, peg 1 vertically should be inserted the center, if but in operation process, misplug into, if namely as Fig. 6 (B) and Fig. 6 (C), insert, owing to can't obtain the rigidity of this peg 1 of stretch-draw, therefore easy and tyre surface 101 disengagings, when under the state that misplugs peg 1, travelling in addition, also possibly can't fully bring into play original function.

Summary of the invention

The present invention proposes in order to address the above problem, the object of the present invention is to provide a kind of tyre surface for inserting peg, wherein, with peg is stable and peg that normally install on the pattern block that is formed at tyre surface inserts in the hole, in addition, under steam, when producing load on the peg, the periphery of the pattern block of tyre surface is together distortion also, can prevent the disengaging of peg.

To achieve these goals, the present invention relates to a kind of tyre surface for inserting peg, wherein, peg is inserted into the peg that is formed in the pattern block and inserts in the hole, and it is characterized in that, along the periphery of the patchhole of above-mentioned peg, according to a determining deviation, a plurality of buffering circular ports form in the circumferential direction of the circle.

Above-mentioned buffering circular port is according to the separately distance arrangement of the center 4～7mm of the above-mentioned patchhole of centre distance in hole, and the quantity of buffering circular port is at least 4～8.

The diameter of above-mentioned buffering circular port is in the scope of 0.8～1.5mm.

In 1/3～1 times the scope of the degree of depth of the patchhole of the degree of depth of above-mentioned buffering circular port on being formed at pattern block.

For the tyre surface for inserting the peg insert of the present invention, in the time of in the pattern block of peg insertion tyre surface, can stably insert, after peg inserted, when external loads put on the peg, pattern block is together distortion also, can reduce the disengaging of peg.

The specific embodiment

With reference to the accompanying drawings, the present invention is specifically described.

Fig. 1 demonstrates in the tyre surface 101 of the tire that is inserted with peg 1 100 shown in Figure 5, be used for to insert the part birds-eye view of the tread block of the patchhole 2 of peg 1 and its peripheral structure, and Fig. 2 is the cutaway view along the I-I line among Fig. 1.

The present invention relates to form the tire of peg patchhole 2 in tread block 3, it is characterized in that along the periphery of above-mentioned peg patchhole 2, according to a determining deviation, a plurality of buffering circular ports 4 are formed in the above-mentioned peg patchhole 2 in the circumferential direction of the circle.

Best, in the buffering circular port 4 that the periphery along above-mentioned peg patchhole 2 forms according to circumferencial direction, the mode of leaving 4～7mm according to the center in hole from the center of patchhole 2 is respectively arranged, and its quantity is at least in 4～8 scope.In addition, the diameter t of above-mentioned buffering circular port 4 can be in the scope of 0.8～1.5mm.

On the other hand, best, the depth d of above-mentioned buffering circular port 4 is in 1/3～1 times scope of the depth D of above-mentioned patchhole 2.

In having the tyre surface of the present invention of such structure, can be as shown in Figure 3, in the time of in the patchhole 2 that peg 1 is inserted pattern block 3, this patchhole 2 is from the position of dotted line, and this situation is followed in the position of expanding solid line to, buffering circular port 4 is also from the position of dotted line, be altered to the position of solid line, peg 1 in correct and stable tram, is installed and is inserted in the tyre surface 101.

In addition, Fig. 4 inserts peg fully the state that peg inserts in the hole for expression the present invention, when its periphery produces load, and the side sectional view of the state of peg pattern block distortion.As shown in Figure 4, after in the patchhole 2 that peg 1 is fully inserted pattern block 3, when externally load L applies along the direction of arrow, the pattern block 3 that is inserted with peg 1 all shown in long and short dash line like that, be out of shape with buffering circular port 4, can prevent the disengaging of peg 1.

For the tyre surface for inserting the peg insert of the present invention, when peg is inserted in the pattern block of tyre surface, can stably insert, after peg inserted, when external loads put on the peg, pattern block is together distortion also, can reduce the disengaging of peg.
