Background
In the running process of the automobile, the steel ring rotates along with the tire, no matter the steel ring rotates or brakes, the friction of all parts in the steel ring and the friction generated by air can both cause the temperature rise of the steel ring and the temperature rise of the steel ring connecting piece. This temperature rise needs to be effectively suppressed to effectively dissipate the internal heat to keep the mechanical accessories operating well and to ensure a long service life. If the heat dissipation is not good, safety accidents such as tire burning or brake failure can be caused. Usually, the spoke part of the steel ring is provided with uniformly distributed air holes, and one of the functions of the air holes is to enhance air convection and radiate heat. The wind hole in the current steel ring is the circular ventilation hole of diameter at 20 ~ 45mm generally, and its radiating effect is not good, and air convection effect is not strong, moreover because the special position requirement of inflating valve, generally will set up the through-hole that supplies the inflating valve to pass again alone outside the ventilation hole, and the technology is loaded down with trivial details relatively.
Disclosure of Invention
To the above problem, an object of the utility model is to provide a big ventilation hole steel ring that radiating effect is good and the air convection is strong does not have an inner tube to solve in the current steel ring because of the ventilation hole aperture is little and lead to the not good and not strong technical problem of air convection effect of radiating effect.
In order to realize the purpose, the utility model discloses a technical scheme as follows:
the utility model provides a large vent hole tubeless steel ring, includes rim and spoke, spoke and rim welding are as an organic whole. The spoke include the dull and stereotyped and be located the cone barrel of the dull and stereotyped one side of installation, the centre bore has been seted up in the dull and stereotyped center department of installation, the installation is dull and stereotyped to be in a plurality of screw has evenly been seted up along circumference in the outside of centre bore. The conical cylinder body is evenly provided with a plurality of oval vent holes along the circumferential direction, the length of the long axis of each oval vent hole is 110-114 mm, and the length of the short axis is 76-80 mm.
Further, the distance between the center of each oval vent hole and the outer surface of the mounting plate is 58-65 mm in consideration of the influence of the position of the vent hole on the strength of the whole spoke.
Further, the edge of each oval vent hole is chamfered on the inner surface and the outer surface of the conical cylinder respectively.
Furthermore, the wheel hub further comprises an inflating valve, wherein an inflating valve mounting hole is formed in the side wall of the wheel hub, one end of the inflating valve is fixedly mounted on the inflating valve mounting hole, and the other end of the inflating valve penetrates out of one of the oval ventilation holes of the spoke.
Further, the number of the oval vent holes is 5-7.
Furthermore, the number of screw holes is 8 ~ 12.
Furthermore, the installation flat plate and the conical cylinder are of a stamping and integral forming structure.
Further, in order to ensure that the rim has enough strength, the rim is made of steel with the tensile strength being more than or equal to 590 MPa.
Furthermore, in order to ensure that the spoke has enough strength, the spoke is made of steel with the tensile strength of more than or equal to 400 MPa.
The utility model discloses following beneficial effect has: compared with the conventional steel ring, the large-ventilation-hole tubeless steel ring has the advantages that the shape of the ventilation hole is larger, the heat dissipation effect is better, the weight of the steel ring can be effectively reduced, the oil consumption of an automobile is reduced, and the cost is reduced. The valve can directly penetrate out of one of the air holes of the spoke, so that the convenience of installing the valve is improved. The utility model discloses a big venthole tubeless steel ring has characteristics workable, low cost, use extensively, that the practicality is strong, crushing resistance is strong.

Detailed Description
The present invention will be further described with reference to the accompanying drawings and the following detailed description.
As shown in figures 1-3, the tubeless steel ring with the large vent hole comprises a spoke 1, a rim 2 and an inflating valve 3, wherein the spoke 1 and the rim 2 are welded into a whole. The spoke 1 comprises a mounting flat plate 11 and a conical cylinder 12 positioned on one side of the mounting flat plate 11, wherein the mounting flat plate 11 and the conical cylinder 12 are of a punching and integrally-formed structure.
