technical field

The utility model relates to a two-way elastic radial plate type honeycomb structure safety wheel, which belongs to the technical field of safety tire design.

Background technique

When vehicles equipped with rubber pneumatic tires run on off-road roads, there are potential safety hazards such as punctures, deflation, and tire blowouts, which will cause the vehicles to lose mobility. When the vehicle is running at high speed, a blown tire can easily cause major traffic accidents. Safety tire technology has a good application prospect in vehicles under special operating environments such as military vehicles, off-road vehicles, and engineering vehicles.

There are two main technical solutions for existing safety tires: one is the improvement on the basis of the original rubber pneumatic tire structure, that is, adding fillers inside the rubber pneumatic tire or increasing the thickness of the sidewall of the rubber pneumatic tire; the other is The non-pneumatic safety wheel with a new structure generally uses the elasticity of springs or other elastic materials to replace the rubber inflatable elasticity. The safety tire of the first scheme increases the weight of the tire significantly due to the addition of fillers inside, resulting in poor maneuverability of the vehicle and increased fuel consumption; the safety tire that realizes deflated support by increasing the thickness of the sidewall of the rubber pneumatic tire, due to the increase in the thickness of the sidewall , the tire stiffness becomes larger, the ride comfort of the vehicle deteriorates, and there is a matching problem with the vehicle suspension. The spring type safety wheel relies on the spring to realize the damping function of the wheel, but because the spring mainly bears the tension pressure, the wheel is also subjected to a certain lateral force when turning, so the wheel of this structural scheme is often poor in lateral stability. In addition, the spring type safety wheel still has a certain time lag when the vehicle is driven and braked, which affects the steering accuracy of the vehicle.
