Problems solved by technology

Lightweight tires are also a trend in the development of the tire industry. It can not only reduce production costs, but also save fuel and reduce environmental pollution. However, the existing tire profile design is obviously difficult to meet the above needs, and it is urgent to propose a new tire profile. , reduce tire weight and rolling resistance, improve disassembly and handling convenience

Embodiment 1

[0020] Embodiment 1. This embodiment proposes a TBR tire profile structure, including a crown portion 1, a sidewall portion 2, a bead portion 3, and a heel portion 4. The overall design of the tire profile is different from the existing conventional design, reflecting the In terms of the number and direction of the design arcs of the sidewall part 2 of the tire, specifically, refer to figure 2 :

[0021] The sidewall portion 2 includes a shoulder section 21 and an upper sidewall arc located above the horizontal axis of the tire, and a lower sidewall arc located below the horizontal axis M of the tire; The two sides of the lower part are tangent to the upper sidewall arc; the upper sidewall arc includes the upper arc and the upper inner arc (the radii of which are respectively R 上 and R 上内 ), and the upper arc and the upper inner arc are concentric arcs whose center is located on the horizontal axis of the tire, and the radius of the upper inner arc is R 上内 and upper arc ra...

Embodiment 2

[0029] Embodiment 2. On the basis of Embodiment 1, this embodiment proposes a tire with the profile structure described in Embodiment 1. Due to the special design of its side profile, the thickness of its upper sidewall is due to the combination of different arc segments and The groove design of the anti-friction part is 0.5mm-1.0mm thinner than the sidewall thickness of conventional tires of the same model. mm, the bead part is designed with a large radius arc (connecting arc), and in order to improve the rigidity and support effect of the bead, the thickness of the bead is 2mm thicker than the normal thickness.

Abstract

The invention relates to a special-shaped outline structure of a TBR (all-steel radial truck) tire and a tire with the outline. The special-shaped outline structure comprises a tire shoulder section, an upper tire side arc, and a lower tire side arc, wherein the tire shoulder section and the upper tire side arc are located at the upper part of a horizontal shaft of the tire; the lower tire side arc is located under the tire horizontal shaft; the tire shoulder section is located at the lower part of a tire crown part, and is in tangent with the upper tire side arc; the upper tire side arc comprises an upper arc and an upper inner arc, wherein the circle center of the upper arc and the upper inner arc is located on the tire horizontal shaft; the lower tire side arc comprises a first lower arc and an ogee section, wherein the ogee section is connected with the first lower arc; the circle center of the first lower arc is located on the tire horizontal shaft; in addition, in order to guarantee the supporting performance of the special-shaped outline tire to a bead part, the thickness of a tire bead location is increased, so that the supporting effect of the special-shaped outline tire is improved; a connecting arc for connecting the ogee section and a tire heel part is arranged under the ogee section; and the radius R<connection> of the connecting arc is 200-240mm. The tire disclosed by the invention has the advantages of being light in weight, low in rolling resistance, convenient to assemble and disassemble, convenient to carry and the like; and the outline of the tire side location is changed, so that in the running process of a vehicle, absorption of impacts from a road surface is facilitated, and the driving comfortableness is effectively improved.

Description

technical field [0001] The invention relates to a TBR tire profile structure and a tire with the profile, belonging to the technical field of tire manufacturing. Background technique [0002] In order to ensure the load-bearing performance of all-steel radial tires in use, most of the sidewall profile design of ordinary all-steel radial truck tires (TBR) still adopts a uniform and excessive arc design from the crown to the bead. Refer to figure 1 , is the design plan diagram of the existing tire profile. The sidewall profile design mainly consists of two arcs above and below the horizontal axis of the tire. This conventional profile design technology has been used for many years. [0003] At present, with the standardization of vehicle transportation and the optimization of road conditions, the driver's driving experience when the vehicle is running is getting more and more attention. At the same time, the single tire weight and fuel consumption of the tire are also getting ...
