Problems solved by technology

[0002] With the improvement of port construction and container carrying capacity, the load-carrying capacity requirements for port reachstacker tires have also increased correspondingly, but the tires will have bead deformation under heavy load conditions, resulting in cutting of the tire bead and rim edge. On the other hand In the case of heavy load, the tire will slip between the rim and the tire during starting and braking, which reduces the operation accuracy of equipment operation and stacking containers

Embodiment Construction

[0012] The rubber sheath structure of the present invention will be described in detail below with reference to the accompanying drawings.

[0013] figure 1 A schematic diagram of the cooperation of the rubber sheath (3) with the rim (1) and the bead (2) according to the present invention is shown. Such as figure 1 As shown, the sheath (3) is arranged between the port bead (2) and the rim (1) to prevent the rim (1) from being worn and to prevent the tire from slipping.

[0014] Such as figure 2 Said, the jacket (3) according to the invention comprises: two substrates (5); and a fiber ply (4) sandwiched between the two substrates. Preferably, said substrate is made of rubber. The substrate needs to be formed by multiple raw materials (natural rubber, carbon black, sulfur, etc.) in an open mill after being mixed for many times, and at the same time, a fiber ply with a width of about 1 / 3 of the sheath length ( Nylon 6-930d / tex), the fiber ply layer is clamped in the base sh...

Abstract

The invention relates to a rubber sheath (3). The rubber sheath (3) is used on a port tire ring (2), and can prevent a rim (1) from being worn and prevent a tire from sliding. The sheath is arranged between the port tire ring (2) and the rim (1) and comprises two substrates (5) and a fiber cord fabric (4) clamped between the two substrates; and the two substrates (5) and the fiber cord fabric (4)are jointed by vulcanization at high temperature and high pressure. The two substrates (5) are made of rubber. The fiber cord fabric (4) comprises two fiber cord fabric layers. The rubber comprises the following components in percentage by weight: 30-40% of natural rubber, 12-18% of butadiene rubber, 3.5-4% of vulcanizing activator, 3-3.5% of rubber antioxidant, 1.5-3% of rubber vulcanizing agent, 35-40% of N550 and 2.5% of aromatic oil.

Description

technical field [0001] The invention relates to a rubber sheath used on a bead of a port, which can prevent wheel rims from wearing and tires from slipping. The sheath will be assembled between the bead of the tire and the rim, mainly to solve the problems of bead cracking and slippage between the tire and the rim caused by the front stacker vehicle during operation. Background technique [0002] With the improvement of port construction and container carrying capacity, the load-carrying capacity requirements of port reachstacker tires have also increased accordingly, but tires will have bead deformation under heavy load conditions, resulting in cutting of tire bead and rim edge, on the other hand In the case of heavy load, the tire will slip between the rim and the tire during starting and braking, which reduces the operation accuracy of equipment operation and stacking containers. Contents of the invention [0003] In order to solve the technical problems described in t...
