Description
Technical field
The utility model relates to tire manufacturing techniques field more particularly to a kind of suspension monorail tires.
Background technique
Currently, suspension type monorail monorail train bears top load and high sinking, surface of tyre can be due to long lasting for rolling
It moves and heat, reaches very high temperature.Present tire be difficult to meet in use suspension monorail tire hyperbar,
Service performance requirement under top load, big deflection ratio, hot environment, not can guarantee the driving safety of suspension monorail,
Life of Tyre is low simultaneously.
Utility model content
In order to overcome problems of the prior art, the utility model provide one kind be able to satisfy hyperbar, top load,
The suspension monorail tire that service performance requires under big deflection ratio and hot environment.
In order to realize above-mentioned goal of the invention, the utility model uses following technical scheme:
A kind of suspension monorail tire, it is and existing including the matrix skeleton body being made of nylon cord layer and tyre bead
Unlike technology, the nylon cord layer includes body ply and reinforcement cord ply, and the body ply includes 4 layers
1400dtex/3 94EPD polyamide fibre body cord and 2 layers of 1400dtex/2 v2 polyamide fibre body cord；The reinforcement cord ply includes
2 layers of 1400dtex/2 v3 polyamide fibre reinforcement cord；The nylon cord layer is followed successively by 4 layers according to sequence from inside to outside
1400dtex/3 94EPD polyamide fibre body cord, 2 layers of 1400dtex/2 v2 polyamide fibre body cord and 2 layers of 1400dtex/2 v3 brocade
Synthetic fibre reinforcement cord；
The tyre bead is double steel ring structures；
The tyre bead and nylon cord layer composite sulfuration are integrated.
The tyre bead includes circle core, and the circle core is 1 layer of 1400dtex/2 v1 polyamide fibre circle core infantees, and chafer is 1 layer
N-80 monofilament screen cloth.
The circle core includes 2 wire loops, and 2 wire loops are laterally to be set side by side, the spread pattern of steel wire in wire loop
It is 5 × 9 layers.
The tire is cross-ply.
Carcass surface is equipped with two longitudinal directions at a distance of the parallel groove of 60mm.With good draining, heat dissipation performance, and energy
Guarantee that the contact area on tire and track road surface is maximum, effectively reduces eccentric wear.
The tire specification is 682 × 190-381.
The utility model has the advantage that
The suspension monorail tire, which has many advantages, such as that sidewall is thick, lateral strength is high, can satisfy suspension monorail
Requirement under tire hyperbar, top load, big deflection ratio, hot environment, at the same have small dimension size, the high life it is excellent
Good characteristic.Tread portion designs two annular ribs ditches, has good draining, heat dissipation performance, and can guarantee tire and track
The contact area on road surface is maximum, effectively reduces eccentric wear.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment；
