Problems solved by technology

For example, the application publication number is the patent application CN110091669A: a kind of airless tire with good cushioning and shock absorption performance. The spoke plates distributed in the circumferential direction are arranged between the inner and outer rims in the airless tire. The outer rim, the spokes in the patent The plates are all made of steel, and the inner rim and hub are integrally formed with aluminum alloy. This kind of airless tire made of metal material still has the following disadvantages in the use test: the whole tire is heavy, which increases the overall weight. The weight of the car will increase fuel consumption or reduce battery life; the mechanical vibration will be large, and the ride comfort will be reduced; after the tire is deformed due to pressure, the recovery ability is not enough

Embodiment 1

[0033] This embodiment 1 discloses a composite material, which is composed of the following components in terms of mass percentage: carbon fiber: 1-5%, graphite powder: 0.5-3%, catalyst NaOH solid: 0.1-1%, co-catalyst acetyl caprolactam: 0.1~1%, the rest is caprolactam.

Embodiment 2

[0035] see Figure 1 to Figure 3 .

[0036] Embodiment 2 discloses an airless tire, which includes a tire tread 1 , an inner hub 2 and an outer rim 4 . Tire tread 1 adopts rubber tread, and it is sleeved on the outer rim 4. The inner hub 2 is connected to the outer rim 4 through spoke plates 3 distributed along the circumferential direction. The outer rim 4 is made of the composite material described in Embodiment 1, and the mechanical strength, impact resistance, toughness and weight of the outer rim made of the composite material are better than those of strip steel.

[0037] In addition, the inner hub 2 is made of traditional aluminum or the composite material described in Embodiment 1. It is found through actual production tests that the performance of the inner hub 2 made of composite material is better than that of aluminum and the inner hub made of composite material is more convenient for subsequent assembly, so in this embodiment 2, the inner hub 2 is also made of ...

Embodiment 3

[0048] see Image 6 , a kind of airless tire is also disclosed in this embodiment 3, and the difference with embodiment 2 is: these three parts of inner hub 2, outer rim 4 and spoke plate 3 are all made of the composite material in embodiment 1, Moreover, during production and processing, the three parts are integrally formed by pouring, so the two ends of the spoke plate 3 do not need to be provided with the hook structure described in embodiment 2. In this embodiment 3, the spoke plate 3 is arc-shaped, " Any one of 3" font or S shape is acceptable.

[0049] In this embodiment 3, the integrated tire body supporting part used to support the tire tread made of the inner hub 2, the outer rim 4 and the spoke plate 3 has greatly improved performance, including cushioning performance, mechanical Strength, impact resistance, toughness and weight are all better than existing airless tires.

[0050] In present embodiment 3, the assembly method of airless tire is:

[0051] Firstly, ...

Abstract

The invention relates to a composite material, an airless tire with the composite material and an assembly method of the airless tire. The composite material is prepared from the following componentsin percentage by mass: 1-5% of carbon fiber, 0.5-3% of graphite powder, 0.1-1% of catalyst NaOH solid, 0.1-1% of cocatalyst acetyl caprolactam and the balance of caprolactam. The airless tire comprises a tire tread, an inner hub and an outer wheel rim, the outer wheel rim is sleeved with the tire tread, the inner hub is connected with the outer wheel rim through spoke plates distributed in the circumferential direction, and the outer wheel rim is made of the composite material. The mechanical strength, the impact resistance, the toughness and the weight of the composite material are far superior to those of traditional aluminum alloy and strip steel; an inner wheel hub, an outer wheel rim and a spoke plate which are made of the composite material are assembled together, and an airless tiremanufactured by combining a rubber tire tread is more excellent in buffer performance.

Description

technical field [0001] The invention relates to the technical field of tires, in particular to a composite material, an airless tire with the material and an assembly method thereof. Background technique [0002] Tires are circular elastic rubber products that are rolled on the ground and rolled on various vehicles or machinery. Usually installed on metal rims, it can support the body, buffer external impact, realize contact with the road surface and ensure the driving performance of the vehicle. Tires are often used under complex and harsh conditions, and they are subjected to various deformations, loads, forces, and high and low temperature effects during driving, so they must have high load-bearing performance, traction performance, and cushioning performance. At the same time, it is also required to have high wear resistance and flex resistance, as well as low rolling resistance and heat generation. [0003] At present, most of the tires used on vehicles are pneumatic ...
