Steel wheel without a tube

Abstract

This is a description of a tubeless wheel for vehicles transporting loads or large numbers of passengers, such as trucks or busses, with an external valve (8), as well as the following products rim (1), disk (2) and valve (8) with the disk (2) mounted on the ledge of the rim (4). The parts have such a geometry that through a combination of distributed factors between the rim (1), disk (2) and valve (8), it is possible to place the valve (8) on the outside of the disk (2) being that the valve seating region is defined by two competing planes free from ridges.

Description

technical field [0001] The present invention relates to a tubeless wheel for vehicles used to transport goods or a large number of passengers, for example for trucks and buses. Background technique [0002] All motor vehicles intended to be used for heavy work, cargo, or the transport of large numbers of passengers are classified as trucks and buses. [0003] These vehicles use tubeless steel wheels, which consist of two parts, a rim and a disc, welded at their joints. [0004] A distinct feature present in these models of tubeless wheels is the positioning of the tire core, hereafter simply referred to as the valve. In this way, the valve can be fitted internally or externally, depending on the structure of the parts making up the wheel and the type of brakes used by the vehicle, eg drum or disc brakes. [0005] wheel with internal valve [0006] The steel wheels used on trucks and buses are known as tubeless wheels with internal valves, where the valve is located on th...

Problems solved by technology

This fact also does not facilitate tire changing operations outside of authorized retail outlets or well equipped workshops once the operator is required to do his best to supply the tire above the rim boss during assembly

[0028] vii) Difficulty filling the tire due to the fact that the smaller diameter of the rim nose provides more space to form the protrusion
