Abstract
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heavy-duty vehicle tire having improved bead portions, wherein the fixing pin 8 is stuck to the outer circumferential portion 31, which is a portion of the outer portion of the bead portion 3, in contact with the rim flange. By providing a tire, characterized in that the rim is pushed inwardly the fixing pin 8, the fixing pin 8 being pushed inwards to sew and press the carcass to suppress the phenomenon that the carcass is pulled down. Therefore, it is possible to reduce the carcass separation and the resulting bead rupture accident.
Description
BACKGROUND OF THE
In heavy-duty tires, the ends of the second and third belts at the tread and the carcass ends at the bead are the most vulnerable parts that are heavily stressed. In particular, in the bead part, accidents occur most frequently when overloading, and such accidents include bead separation between components forming a bead and bead bursts in which such separation phenomenon is developed.
Heavy-duty vehicle tires are subjected to constant tension and compression movement at the end of the carcass when driving, which causes the carcass to be pulled down, and the carcass that is being pulled down rotates the bead core.
This movement eventually separates the elements forming the bead portion, and when the separation between these elements progresses, the carcass turn up is released and a burst accident occurs in the bead portion. .
In order to prevent the separation (Bead Sepa.) Or bead (Bad Burst) between the bead components, it is conventional to form a layer of reinforcement at the carcass end or to concentrate the stress at the carcass end I have been trying to disperse. However, despite such efforts, it was impossible to completely eliminate the bead accident.
Accordingly, the present invention is to solve the problem of providing a tire that can reduce the element separation and rupture accident in the bead portion.
In order to solve the above problems, the present invention sees that the accident in the bead part is drawn down by the carcass, and attempts to reduce the accident of the bead part by providing a means of preventing the carcass from being drawn down. As a means for preventing the carcass from being pulled down, the present invention provides a means for stitching and pressing the carcass with a fixing pin that sticks inward from the outside of the bead portion to prevent the carcass from being pulled out.
According to the present invention, which provides the above means, when the tire is mounted on the rim, the rim pushes the fixing pin inward, and the fixing pin pushed inward seizes and presses the carcass to suppress the phenomenon of the carcass being pulled down. Therefore, it is effective to reduce the carcass segregation and the resulting bead rupture accident.
