Wheel assembly for load-carrying vehicle

Abstract

The invention discloses a wheel assembly for a load-carrying vehicle. The wheel assembly comprises a tubeless tyre and a rim. The wheel assembly is characterized by further comprising an inner tube installed in a cavity of the tubeless tyre and a blanket, wherein the inner tube is located between the blanket and the tubeless tyre. The rim is a one-piece 15 degree deep groove rim or an independently designed multi-piece 15 degree deep groove rim. The blanket is designed according to dimensions of the rim and the inner contour of the tubeless tyre. The inner tube is designed according to dimension of inner contours of the tubeless tyre, the rim and the blanket. According to the wheel assembly for the load-carrying vehicle disclosed by the invention, the overall loading capacity, the durability, the impact puncture resistance and the gas protecting performance of the tyre assembly are improved, applicability of the tubeless tyre on various road conditions is expanded, and the problem that the rim of the tubeless tyre is easy to deform or air leakage in mine lots or bad roads caused by the upwarp of the tire bead and the bead toe is solved.

Description

technical field [0001] The invention relates to a wheel assembly for a load-carrying vehicle, in particular to a wheel assembly for a load-carrying vehicle with a pneumatic inner tube. Background technique [0002] figure 1 It is prior art to have inner tube truck tire and wheel rim combination, such as figure 1 As shown, its disadvantage is that the assembly interference between the tire and the rim is small. During the use of heavy loads, there is a circumferential and axial slip between the tire and the rim mating surface, resulting in the tire rim. Increased heat generation, easy to early damage. [0003] If the interference fit between the tire rims is simply increased, it will inevitably lead to difficulty in assembling the tire rims and damage to the rim of the tire; at the same time, after the tire is punctured, it will quickly leak air, and the lack of air will cause the vehicle to be out of control, which will affect the driving safety of the vehicle. There is a...

Problems solved by technology

But on the one hand, due to the shallow depth of the radial contact groove between the tire and the rim, the overall load capacity of the tire is reduced, and its load capacity is not particularly ideal; It cannot effectively ensure that the tires, inner tubes, pads and rims are always in a tight fit state, and it is prone to relative movement or relative movement between the tires, inner tubes and pads and the rim during the rolling of the wheel, which will cause wear and tear and shorten the service life. shortening; in addition, this kind of material mainly relies on simple material improvement, enhancement or reinforcement measures, and its manufacturing cost is also high
