Abstract

The invention provides a bead bundle formed hollow for car tires, with a reduction in the friction between bead wires and weight of bead bundle.

Description

Improved the automobile tyre of bead part
Technical field
The present invention relates to improve the automobile tyre of the bead core of bead part.
Background technology
Bead core in the tire (Bead core) constituted owing to being that many tyre bead metal filaments are closely stacked in the past, produced heat so there is closely stacked tyre bead metal filament phase mutual friction, and made the phenomenon of bead part sclerosis.In addition, so stacked tyre bead metal filament is too heavy, and becomes the reason that worsens the motor vehicle fuel expense.
Summary of the invention
The invention provides by hollow form ground and form bead core, reduce the friction between the tyre bead metal filament, and reduce bead core weight improvement the automobile tyre of bead part.
Description of drawings
Fig. 1 is the local longitudinal sectional view of tire of the present invention.
Fig. 2 is the local amplification stereogram of the bead core of main portion of the present invention.
The specific embodiment
Below, with reference to the accompanying drawings, the present invention will be described.
The invention is characterized in that hollow form ground forms the bead core of the bead part of automobile tyre.
That is, automobile tyre of the present invention is made of tyre surface 1 and sidewall 2 and bead part 3, and in this bead part 3 bead core 4 is set, and it is characterized in that, hollow form ground forms above-mentioned bead core 4.
At this, this bead core 4 is owing to normally be made of a plurality of tyre bead metal filament pieces, so when forming bead core by tyre bead metal filament piece, the present invention is such as shown in Figure 2, preferably with netted cylindrical shape formation tyre bead metal filament.Each tyre bead metal filament is certainly formed by the mono-metal filament, but and the metal filament of the thin diameter of twisted form.
So the present invention who constitutes, because bead core 4 forms hollow form, so tyre bead density wiry is lower, and the friction between the metal filament is less, therefore, can reduce the cal val that friction caused between the tyre bead metal filament.
In addition, the present invention has following effect, promptly because bead core 4 is a hollow form, thus form this volume at volume with regulation, and can reduce its weight, finally reduce the weight of tire, and be expected to improve the fuel cost of vehicle.

Claims (2)

1. automobile tyre that improves bead part, by tyre surface (1) and sidewall (2) and bead part (3) formation, and bead core (4) is set in this bead part (3), this automobile tyre is characterised in that, above-mentioned bead core (4) forms hollow form, and the tyre bead metal filament of the bead core of above-mentioned hollow form (4) forms with netted drum.
2. the automobile tyre that improves bead part according to claim 1 is characterized in that, each tyre bead that constitutes above-mentioned bead core (4) is the thin diameter metal silk of twisted and forming.
