Description

Pneumatic tire

Technical field

Pneumatic tire technical field is the utility model is related to, refers in particular to heavy-load automobile pneumatic tire.

Background technology

With the development of automobile industry, load-carrying vehicle horsepower is constantly lifted, and vehicle is still reachable in the case of load-carrying is larger To higher speed.Vehicle is larger in load-carrying, runs at high speed when the preferable highway of road conditions, national highway, and tire produces more Heat, the durability of tire is had an impact, has a strong impact on the service life of tire.

The load-carrying size of vehicle, there is different demands to the thermal diffusivity of tire.In general, vehicle load is smaller, at a high speed During traveling, the heating of tire is relatively small；Vehicle load is larger, and when running at high speed, the heating of tire is relatively large, now to wheel The heat dispersion of tire has higher requirement.

In the prior art, to improve tire heat dispersion, often through the thermal diffusivity and pattern for improving tyre stock Optimization design, the improvement can lift the heat dispersion of tire, but in the tight lotus of use condition, if tire is under higher load, When running at high speed, tire can produce more heat, cause tire to break down.So heat dispersion of heavy-load automobile tire Thus produced up for further optimization, this case.

Utility model content

The purpose of this utility model is to provide pneumatic tire, to improve the heat dispersion of pneumatic tire, suppression inflated wheel Tire temperature rises, and improves the durability of pneumatic tire, while save elastomeric material.

In order to reach above-mentioned purpose, solution of the present utility model is：

Pneumatic tire, including tire lip, sidewall and fetus face；Fetus face both sides connect sidewall, the tire of both sides respectively Sidepiece connects tire lip respectively；At least one peripheral recess at least is set on the tire lip of side in the tire lip of both sides.

Further, the bottom of peripheral recess passes through circular sliding slopes transition.

Further, peripheral recess includes 1 to 8 spaced circumferential recess.

Further, the depth of circumferential recess is 0.5mm to 5mm.

Further, the centre distance between adjacent circumferential groove is 2mm to 5mm.

Further, multiple peripheral recess are set, form multiple deformation regions and multiple air draught regions, each peripheral recess It is highly identical.

After such scheme, the utility model at least sets at least one in the tire lip of both sides on the tire lip of side Individual peripheral recess, for pneumatic tire when running at high speed, while carrying high load capacity, the peripheral recess of tire lip produces deformation, circumferential Recess plays cushioning effect, slows down the deformation to tire lip, so as to reduce the heating of tire；The peripheral recess of tire lip can also make Air forms air-flow, is improved by air draught rejecting；The peripheral recess reduces the rubber bodies of pneumatic tyre lip simultaneously Product, can further suppress the generation of heat by reducing rubber volume.Therefore, the utility model can suppress pneumatic tire temperature Degree rises, and improves the durability of pneumatic tire.

Label declaration

The peripheral recess 11 of tire lip 1

The sidewall 2 of circumferential recess 111

Fetus face 3.

Embodiment

The utility model is described in detail below in conjunction with drawings and the specific embodiments.

Refer to described in Fig. 1 to Fig. 3, the utility model discloses pneumatic tire, including tire lip 1, sidewall 2 and fetus face 3。

As shown in figure 1, fetus face 3 contacts with ground, the both sides of fetus face 3 connect sidewall 2, the sidewall 2 of both sides respectively Tire lip 1, the tire lip 1 and wheel rim of both sides are connected respectively（Not shown in figure）Contact.At least side in the tire lip 1 of both sides Tire lip 1 at least one peripheral recess 11 is set, in this implementation, peripheral recess 11 is provided with the tire lip 1 of both sides.If When putting multiple peripheral recess 11, multiple deformation regions and multiple air draught regions are formed, each peripheral recess 11 is highly identical.

The peripheral recess 11 on tire lip 1 so that pneumatic tire is when running at high speed, while carrying high load capacity, tire lip 1 Peripheral recess 11 produce deformation, peripheral recess 11 plays cushioning effect, slows down the deformation to tire lip 1, so as to reduce tire Heating；The peripheral recess 11 of tire lip 1 can also make air form air-flow, be improved by air draught rejecting；This week simultaneously The rubber volume of pneumatic tyre lip 1 is reduced to recess 11, can further suppress the production of heat by reducing rubber volume It is raw.

As shown in Figures 2 and 3, it is preferably, the bottom of peripheral recess 11 is by circular sliding slopes transition, to reduce stress collection In, further reduce heat and produce.Peripheral recess 11 includes 1 to 8 spaced circumferential recess 111.Circumferential recess 111 Depth is 0.5mm to 5mm.Centre distance between adjacent circumferential groove 111 is 2mm to 5mm.

Preferred embodiment of the present utility model is the foregoing is only, not to the limitation of this case design, all setting according to this case The crucial equivalent variations done of meter, each fall within the protection domain of this case.
