Safety wheel with oppositely-opened type aluminum-alloy wheel rim with large offset distance for special vehicle

Abstract

The invention relates to a safety wheel and particularly relates to a safety wheel with an oppositely-opened type aluminum-alloy wheel rim with large offset distance for a special vehicle. The problems that a traditional wheel has large weight and is also inconvenient to assemble are solved. The safety wheel with the oppositely-opened type aluminum-alloy wheel rim with the large offset distance for the special vehicle comprises a tubeless tyre, a hard supporting body and an oppositely-opened type aluminum-alloy wheel rim with large offset distance, wherein the structure of the hard supporting body is the structure of a supporting body which is a three-section type detachable structure, and the offset distance of the wheel is not smaller than 90mm. The material of the hard supporting body is hard nylon. Compared with a steel wheel rim with the same specification, the weight of the safety wheel is reduced by more than 50 percent; compared with a rubber supporting body with the same specification, the weight of the hard supporting body is reduced by about 55 percent, so that the weight of an entire wheel assembly is greatly decreased; and the safety wheel with the oppositely-opened type aluminum-alloy wheel rim with the large offset distance for the special vehicle is beneficial to enhancing the operating and controlling performance of a vehicle and lowering the energy loss of the vehicle. The safe running mileage can be obviously enhanced. The assembling process is simple, the assembly and the disassembly of the wheel assembly can be carried out without exclusive tyre pressing and installing equipment, the assembling process is simplified, the assembling time is shortened, and the cost of logistic guarantee is also lowered.

Description

Technical field: [0001] The invention relates to a run-flat safety wheel suitable for special vehicles, in particular to a run-flat safety wheel using a split-type aluminum alloy rim with a large offset distance. Background technique: [0002] The wheel assembly is the running part of the vehicle, and the force and moment transmitted by the wheel assembly realize the bearing and motion functions of the vehicle. It has important functions such as carrying the vehicle, reducing driving resistance, alleviating driving impact, protecting the vehicle and the road surface, and to a large extent affects the handling stability, occupant comfort and ride comfort of the vehicle. [0003] Based on the importance of wheels to various performances of vehicles, various wheel components have been developed on the market. There are: [0004] 1. Tires are gradually going tubeless. Tubeless tires have low heat generation, light weight, good balance, no instant loss of air, good high-speed ...

AI Technical Summary

Problems solved by technology

The rubber support body has good elasticity, which can cushion the impact of the wheel to a certain extent, but the friction between it and the tire is large, and it is easy to cause the tire to burn due to friction and heat.

[0007] Military vehicles and some other special vehicles, due to high mobility requirements, poor road conditions, and difficult maintenance guarantees in the fi
