Abstract

The utility model relates to an improved automobile tyre, which comprises a tyre body and an accessorial opening. The utility model is characterized in that the shape of the accessorial opening, which is matched with the shape of a septal lamella of a tire steel ring, is changed from a direct inserting tyre structure into the >-shaped pressing type embedded structure with an opening which faces to outward. The utility model can make the accessorial opening accept the pressure force which is toward a shaft center. Consequently, the accessorial opening is made into thinner under the precondition of satisfaction of the strength requirement. The utility model reduces the occupation area of a wheel net of the steel ring, improves ventilation and heat dissipation in the tyre and between the tyres which are arranged in parallel, is capable of effectively preventing deformation, explosion and uneven abrasion of the tyre, and makes the dynamic balance evenly. The product has very obvious effect that the utility model is used for automobiles for loading.

Description

A kind of improved motor tire

The utility model relates to a kind of improved motor tire.

At present its rim of the mouth, both sides of motor tire of using and the fit shapes of steel ring former be oblique, relative outward " " shape, when tire installs on the steel ring, its rim of the mouth can only directly be stuck on the former of steel ring both sides, the rim of the mouth collapses out and causes fried tire when preventing tire force, the rim of the mouth just must be done very thickly, and one takies wheel web area and influence internal heat dissipating; Two come the meeting of tire force center near tyre surface, make the side of tire stressed big and be out of shape (bulge), tread of tyre with be not plane and be arc-shaped curved surface when contacting, thereby cause tire dynamic equilibrium inequality, treadwear concentrates on centre portion and the life-span weak point, and anti-impact force reduces.

The purpose of this utility model is to provide a kind of and makes that tire is indeformable, dynamic equilibrium and treadwear is even, anti-impact force strong, a kind of improved motor tire that is difficult for blowing out.

Technical scheme is as follows:

A kind of improved motor tire comprises carcass, side, rim of the mouth, tyre surface, the rim of the mouth, both sides be opening outwardly, relative "＞" shape.

The utility model is owing to adopted such scheme, be used in combination supporting improved tyre rim, and make tyre rim under the prerequisite of proof strength, the area that takies the steel-tired wheel net reduces, can effectively improve the inside tires heat dissipating state, the more important thing is the tire force center is moved down towards the axle center, the rim of the mouth has been increased towards the pressure in axle center and make tire not yielding, tyre surface becomes the plane and weares and teares evenly, and the dynamic equilibrium meeting is better, and the utility model is difficult for blowing out, easy-to-break layer not, life-span greatly prolongs, and is used for 900 type rates of loading through test, and effect is very outstanding.

Be further described below in conjunction with accompanying drawing 1-3 and embodiment.

Fig. 1 is the cross-sectional view that present tire that is using and steel ring are assembled into one;

Fig. 2 is a sectional structure scheme drawing of the present utility model.

Fig. 3 is the cross-sectional view that the utility model and supporting improved steel ring are combined.

Embodiment:

A kind of improved motor tire, comprise carcass 1, side 2, rim of the mouth 3, tyre surface 4, rim of the mouth 3 is "＜" shape of opening direction outside tyre side, and rim of the mouth, both sides 3 opening directions are opposite, symmetrical, the former knuckle of the corner dimension in rim of the mouth 3 and supporting steel ring coincide, and present embodiment is designed to 120 °.Owing to match with the structure that the former of supporting steel ring has adopted the knuckle embedding to press in rim of the mouth 3, thereby rim of the mouth 3 does not resemble the straight line nested structure that prior art (shown in Figure 1) is adopted, rim of the mouth, carrying back can be subjected to making rim of the mouth 3 be difficult for collapsing towards the pressure in axle center and hold, tire center of effort descends to the axle center simultaneously, tire is not yielding, and dynamic equilibrium is even, the treadwear unanimity, easy-to-break layer not, the life-span prolongs.Because adopt this structure, rim of the mouth 3 can also be done thinlyyer, thereby save steel-tired wheel net space, improve in the tire and the radiating effect between the tire arranged side by side.

Claims

1. an improved motor tire comprises carcass (1), side (2), rim of the mouth (3), tyre surface (4), it is characterized in that: rim of the mouth, both sides (3) for opening outwardly, relative "＞" shape.
