A non-pneumatic tire with a comfortable elastic structure tread

Abstract

A non-inflatable tire having a tread of a comfortable elastic structure, comprising an inner ring (1), a radial plate (2), supporting plates (3), and an outer ring (4), which are molded integrally. The inner ring (1) and the outer ring (4) are of a concentric structure. The radial plate (2) is connected to the outer ring (4) and the inner ring (1) in a common central axis plane of the outer ring (4) and the inner ring (1). The supporting plates (3), connected to the outer ring (4) and the inner ring (1), are disposed on left and right sides of the radial plate (2), respectively. The supporting plates (3) on the left and right sides of the radial plate (2) are disposed oppositely. The supporting plates (3) are vertically connected to the radial plate (2). Included angles of 15-75° are formed between the supporting plates (3) and inner ring radial planes formed by connecting lines between the supporting plates (3) and the inner ring (1). The outer ring (4) is provided with an annular middle groove (41). The outer ring (4) is partitioned into a left outer ring and a right outer ring by means of the annular middle groove (41). The bottom of the annular middle groove (41) protrudes from the inner surface of a tread (6) and is connected to the radial plate (2). The left outer ring and the right outer ring are provided with at least one outer ring longitudinal groove (42) parallel to the annular middle groove (41), separately. The tire has a relatively good road holding performance, slip resistance and comfort.

Description

technical field [0001] The invention relates to a non-pneumatic tire, in particular to a non-pneumatic tire with a comfortable elastic structure tread. Background technique [0002] Car tires are a general term for tires, usually made of wear-resistant rubber materials, and can be divided into pneumatic tires and solid tires. Inflate enough gas to obtain comfortable support in the sealed rubber cavity. The disadvantage of pneumatic tires is that the rubber material of the tread is easy to wear. Because it is inflated support, there is also the possibility of tire blowout. Secondly, whether it is a rubber solid tire or a polyurethane solid tire They are all slow to run, uncomfortable, and prone to internal heat generation and cannot run for a long time. Later in the research, it was found that polyurethane materials were used to make non-pneumatic tires with integrated and connected elastic rings, which did not need to be inflated to ensure that the driving vehicle would not...

Problems solved by technology

Among them, 93103843 X also describes inserting inserts into the middle web of the non-pneumatic tire to optimize and enhance the comfort of the tire, but since both of them are equipped with rubber treads on the outer ring, although part of the comfort is solved However, since polyurethane materials and rubber materials are two different materials, and tires are high-strength running wear parts, the bonding between them is a difficult technical problem. Even if this bonding technology can be solved, large quantities It is also difficult to ensure that the bonding strength of each tire is the same during production, and the bonding process is difficult to achieve, so their products are difficult to industrialize

In addition, because the hardness of the outer ring is large and there is no optimized structure, even if the outer ring is glued to the rubber tread, it cannot achieve the comfort close to that of a rubber pneumatic tire.
