Embodiment 1

[0049] Embodiment one, refer to figure 2 , one of the preferred ways, including but not limited to figure 2 The embedding method in the polyurethane rubber layer is embedded with a heat-conducting member 400. The heat-conducting member is preferably a composite structure of heat-conducting rubber and graphene fiber filaments, or a composite structure of heat-conducting rubber and steel mesh cylinder. Regarding the composite structure and style, detailed below.

[0050] combine image 3 and Figure 4 , the structure of the present invention can be understood in more detail through the manufacturing process of the heat conducting member.

[0051] The heat conduction member is composited by guiding rubber and graphene fiber filaments, and the composition ratio of the heat conduction rubber is as follows: the following raw materials in terms of mass percentage: polyurethane resin 45-55%, heat conduction powder 40-20%, 10-20% of the flame retardant, and the remaining foaming ...

Embodiment 2

[0062] refer to Figure 6 , a composite reinforcement layer 500 is provided on the surface of the rim, and cords are provided in the reinforcement layer. The cords can be non-metallic cords or stainless steel wire mesh cords, which have the same effect.

Embodiment 3

[0064] refer to Figure 7 , in this embodiment, there is no heat sink or expansion in the heat conduction member, that is to say, the heat dissipation path only exists between the serious heat generation part and the rim, and the heat dissipation performance of the rim can also be used for partial heat dissipation. Effect.

Abstract

The invention discloses a polyurethane solid tire and a corresponding manufacturing method. It includes a rim, a hub and a polyurethane rubber layer, wherein the polyurethane rubber layer is attached to the outer surface of the rim through an adhesive process, and is characterized in that it also includes a heat conducting member built inside the polyurethane rubber layer, and the heat conducting member is at least partly Located in the center of the heat generating area of ​​the polyurethane rubber layer, at least partly attached to the surface of the rim, the process of adding a heat conducting member is added in the manufacturing process, and the present invention has more excellent heat dissipation performance.

Description

technical field [0001] The invention relates to the technical field of solid tires, in particular to solid tires used on engineering vehicles in industrial and mining situations. Background technique [0002] Taking engineering forklifts as an example, polyurethane solid tires are usually used in factories, mines, etc. Solid tires can better meet special requirements such as puncture resistance, tear resistance, no need to inflate, high utilization rate, and low maintenance rate. [0003] Among them, polyurethane solid tires can be subdivided into bonded and non-bonded types according to the combination with the rim. Among them, the bonded structure refers to the direct pouring of polyurethane and vulcanization on the rim to form an integrated structure. The non-adhesive structure means that the polyurethane elastomer is fixed on the rim by mechanical set. In either form, there is a problem of heat generation inside the polyurethane elastomer. [0004] With regard to the i...
