Abstract
The invention belongs to tire equipment technical fields, are related to a kind of all-steel radial tyre shoulder Fin structures, circumferentially shape is uniformly arranged several grooves to tire shoulder alar part, at an acute angle between groove and tire vertical center line;Groove includes outer groove and inside groove.The present invention solves middle-long distance transportation type card car all-steel radial tyre shoulder stress concentration, the excessive problem of heat reduces the problems such as shoulder is empty, improves the service life of tire, the security performance of tire is promoted, while improving the case where reducing tyre shoulders eccentric wear to a certain extent.
Description
Technical field
The invention belongs to tire equipment technical fields, are related to a kind of all-steel radial tyre shoulder Fin structures.
Background technology
With the development and progress of country, the application of middle-long distance transportation type card car all-steel radial tyre is more and more,
The performance of the tread shoulder of tire proposes the newer requirement of higher, but due to middle-long distance transportation type card car all-steel meridian line wheel
The features such as tire load is high and speed is fast tread shoulder stress concentration, heat are excessively high, the problems such as shoulder is empty usually occur.Simultaneously because wheel
The design of tire itself, manufacturing issue cause tyre shoulders inordinate wear excessive using problem, and Life of Tyre is caused to decline,
The reason of leading to problems, is difficult to determine, so it is difficult to fundamentally solving.
Invention content
In view of the above-mentioned problems, providing a kind of all-steel radial tyre shoulder Fin structures, which can effectively carry the present invention
High tire shoulder position heat dissipation effect, improves the service life of tire.
Technical solution according to the invention:A kind of all-steel radial tyre shoulder Fin structures, it is characterised in that:Tire shoulder alar part
Circumferentially shape is uniformly arranged several grooves, at an acute angle between groove and tire vertical center line;Groove includes outer groove and inside groove.
As a further improvement on the present invention, the vertical distance between the notch upper extreme point and tire shoulder the outer end point of the groove
For 5.5 ~ 6mm.
As a further improvement on the present invention, the width of rebate of the outer groove is 5.5mm, and the depth of outer groove is 8.5mm, interior
The width of slot is 2mm.
As a further improvement on the present invention, the lower notch of the outer groove is arc transition structure.
As a further improvement on the present invention, it is 30 ° ~ 31 ° in angle between the groove and tire vertical center line.
As a further improvement on the present invention, chamfering is formed between the notch upper extreme point and the outer end point of tire shoulder of the outer groove
Structure.
The technical effects of the invention are that:The present invention solves middle-long distance transportation type card car all-steel radial tyre shoulder
Stress concentration, the excessive problem of heat reduce the problems such as shoulder is empty, improve the service life of tire, promote the security performance of tire,
The case where raising reduces tyre shoulders eccentric wear to a certain extent simultaneously.
Description of the drawings
Fig. 1 is the structural diagram of the present invention.
Specific implementation mode
The specific implementation mode of the present invention is further described below in conjunction with the accompanying drawings.
As shown in Figure 1, the present invention is a kind of all-steel radial tyre shoulder Fin structures, circumferentially shape is uniformly distributed for 1 alar part of tire shoulder
Several grooves 2 are set, it is at an acute angle between groove 2 and tire vertical center line, in concrete practice, during groove 2 is vertical with tire
Between heart line in angle be 30 ° ~ 31 °;Groove 2 includes outer groove 2-1 and inside groove 2-2.
Vertical distance between 1 the outer end point of notch upper extreme point and tire shoulder of groove 2 is 5.5 ~ 6mm.
The width of rebate of outer groove 2-1 is 5.5mm, and the depth of outer groove 2-1 is 8.5mm, and the width of inside groove 2-2 is 2mm.
The lower notch of outer groove 2-1 is arc transition structure, and in tire production, gas vent is placed at arc transition structure,
It can effectively prevent occurring starved round mouth phenomenon at this in sulfidation.
Chamfering structure is formed between the notch upper extreme point and the outer end point of tire shoulder 1 of outer groove 2-1.
Groove 2 in product of the present invention gos deep into tire shoulder, and it is long to improve tire for the effective heat dissipation for helping shoulder region
Apart from prolonged driveability, the service life of tire is improved, reduces the shoulder sky phenomenon caused by shoulder heat is excessively high, is promoted
The security performance of tire.
In addition, anomalies in material distribution or Slurry pump caused by due to design reasons, manufacture, lead to tire tread shoulder
Occur exception under contouring shape load, occurs rolling friction between ground, exacerbate the abrasion of tread shoulder, tire occur
The situation of eccentric wear, the invention have certain space since tire shoulder alar part devises groove 2 between pattern block on tire shoulder and alar part,
The abnormal deformation that pattern block on tire shoulder occurs under load has certain buffering leeway, can slow down the situation of tire shoulder eccentric wear.
