Abstract
The invention discloses a novel inner supporting device for a tire, which is characterized by comprising an annular belt-shaped structure body axially sleeved on the outer ring surface of a rim in a cavity of the tire. The invention adopts a large-size and axial dismounting/mounting mode, obtains the good effect of simple and convenient operation and really ensuring the tire burst safety.
Description
Technical Field
The invention relates to a safe explosion-proof tire supporting device, in particular to an inner supporting body without an inner tube.
Background
The current widely used tubeless tires are all pneumatic tires, and once the tires are punctured, scratched and the like by sharp objects, air leakage, knocking over and even tire burst can occur, so that great potential safety hazards are caused. With the relevant data statistics, 46% of traffic accidents are caused by tires, of which 70% of the accidents occur, and the mortality rate of the accidents of tire burst is extremely high when the vehicle runs at high speed. And the inner support structure who exists among the prior art mostly uses the fixed mode of axle to connect after articulated or voussoir inserts, and this kind of connected mode is to the impact of supporter when can't reducing the tire burst effectively, easily causes the decomposition of supporter.
Therefore, a tire support structure that can alleviate the impact force after a sudden pressure loss of the tire, and maintain proper tire deflection and vehicle ride capacity, would be highly desirable to those skilled in the art.
The invention adopts a large-size and rim axial dismounting/mounting mode, and obtains good effects of simple operation, practicality and reliability.
Disclosure of Invention
The novel tire inner supporting device is an annular belt-shaped structure body which is axially sleeved on the outer annular surface of a rim in a tire cavity.
The material of the annular belt-shaped structure body is macromolecule, metal or a combination of macromolecule and metal.
The annular belt-shaped structural body is formed by splicing the whole body or multiple sections without interfaces, so that the strength is ensured, the support is uniform, and the disassembly and the assembly are convenient.
The performance indexes of the annular belt-shaped structure body such as the elastic modulus, the radial height of a wheel rim, the width of an inner ring surface and an outer ring surface are determined according to the requirement of the tire, the support of the tire tread is ensured when the tire is in a short of air or flat, and the tire is prevented from knocking over.
The diameter of the inner ring of the annular belt-shaped structure body is smaller than that of the outer ring surface of the rim, and the annular belt-shaped structure body is firmly combined with the rim by interference fit and displacement is prevented.
The annular belt-shaped structure body can be provided with an axial through hole, so that the requirements of weight reduction and elastic modulus adjustment are met.
The inner and outer ring surfaces of the annular belt-shaped structure are flat surfaces and can also be concave-convex surfaces.
A plurality of annular belt-shaped structures can be arranged on one rim in parallel, so that the application of super single tires is met.
