Problems solved by technology

[0005] Aiming at the problem that the strength and comfort of tires in the prior art cannot be effectively balanced, the present invention proposes a tire with a triangular inner cavity and a processing method thereof. Along the circumference, there is an inner cavity support part that runs through the head and tail. The inner cavity support part is a Lello triangle inner cavity with a closed longitudinal section shape. The Lello triangle has both triangular stability and circular overall force uniformity characteristics, which is beneficial to ensure that the tire has good support strength during riding, and the comfort can also be guaranteed

Embodiment 1

[0065] A kind of inner chamber of the present embodiment is the tire of the shape of Lelo triangle, such as Figure 1~2 As shown, it includes a tire green strip 1 extruded by a screw extruder. The tire green strip 1 includes a crown 11, a tire belly 12 and a sidewall part 13, and the sidewall part 13 is wrapped around the periphery of the rim. The core of the tire billet 1 is provided with an inner cavity support portion along its circumference, and the inner cavity support portion is a closed Lello triangular inner cavity 2 in a longitudinal section shape. Since the Lello triangle has both triangular stability and roundness The whole shape is uniformly stressed, and its strength and stability are good; combined with the material formula of the tire, the size of a single Lello triangular inner cavity 2 accounts for 30% to 60% of the cross-sectional size of the tire, so as to ensure the load and stability of the tire. Comfort requirements, if the load and comfort are met, the h...

Embodiment 2

[0068] A kind of inner chamber of the present embodiment is the tire of the shape of Lai Luo triangle, and basic structure is the same as embodiment 1, difference and improvement are: as image 3As shown, the elastic medium 21 is filled in the inner cavity 2 of the Laylo triangle, and the elastic medium 21 is a gas medium or a solid medium, and the gaseous state is mainly an inert gas such as nitrogen, and the solid one is a non-metallic elastic medium, mainly composed of non-metallic elastic medium. Metal elastic members such as plastics or foaming and other lightweight cushioning materials, etc., so that the tire has good support strength during riding, and can also have riding comfort, and can reduce the weight of the tire and reduce the riding process. energy loss.

Embodiment 3

[0070] A kind of inner chamber of the present embodiment is the tire of the triangular shape of Lai Luo, and basic structure is the same as embodiment 2, difference and improvement are: as Figure 14 As shown, an elastic member 4 is placed in the Rilo triangular inner cavity 2 along its circumference, and the outside of the elastic member 4 is in contact with the inner wall of the Rilo triangular inner cavity 2 and is partially embedded in the tire on the periphery of the inner cavity. In the embryonic strip 1, thereby preventing the elastic member 4 from sliding in the inner cavity 2 of the Leroy triangle, thereby affecting the force uniformity of the tire. When the tire is under stress, the elastic member 4 plays a supporting role in the interior of the Lello triangular cavity 2. Due to the nature of the elastic member 4 itself, it can also reduce the stress concentration caused by the pressure of the tire and ensure the comfort of riding. performance, and can save energy co...

Abstract

The invention discloses a tire with a Reuleaux triangle inner cavity, and a processing method of the tire, and belongs to the technical field of tire processing. According to the tire with the Reuleaux triangle inner cavity, and the processing method of the tire, an inner cavity supporting part is formed in a tire blank strip core part in the circumferential direction of the tire blank strip corepart, and is a Reuleaux triangle inner cavity with a closed longitudinal section, the inner cavity is filled with an elastic medium, the elastic medium is a gas medium or a solid medium so as to achieve both the supporting strength and the riding comfort, a plurality of groups of Reuleaux triangle inner cavities are formed in the tire blank strip core part in the circumferential direction and arein a separated or tangent state in the tire blank strip, and any tip of each Reuleaux triangle inner cavity is centripetally or centrifugally distributed. According to the invention, the positions, the distances and the distribution states of all the Reuleaux triangles are adjusted through factors such as the dead weight, the load, the actual environment, the speed limit and the like of the vehicle, so that the supporting force and the comfort degree in the tire riding process are balanced, and the optimal state is found.

Description

technical field [0001] The invention relates to the technical field of tire processing, and more specifically relates to a tire with an inner cavity in the shape of a Relo triangular shape and a processing method thereof. Background technique [0002] Tires are divided into pneumatic tires and non-pneumatic tires. In view of the current traditional pneumatic tires are widely used because of their mature production technology, cushioning, good riding comfort and good load bearing. However, as a large number of vehicle safety accidents caused by tire blowouts, wear and unstable operation are increasing, air-free tires without tubes have attracted more and more attention because of their high safety, energy saving and environmental protection. . Non-pneumatic tires are divided into two categories: solid tires and hollow tires. Hollow tires largely solve the defect of bumps caused by insufficient resilience during riding with non-pneumatic tires. However, the existing hollow t...
